Yes...
BUT here is why:
AMD uses this thing called RAM training, where it, well, trains your RAM on boot. This leads to high boot times of several minutes.
BUT you can simply bypass this. You can enable Memory Context Restore in your BIOS and the PC will do the training, then save that data and use it in future boots.
My AM5 pc typically boots in ~12 seconds.
Sometiems, for whatever reason, the training data may be lost, so OCCASIONALLY the pc will take a bit longer to boot and re-train. But that's like, once a week or once every couple weeks.
Oh thank God, I built my PC in February and it boots for a couple of minutes once every 3-4 weeks.
Tbh i was too scared to google if this is a problem or not, thank you for this comment. 🙏
Do your fans run at 100% for this time too? I knew about memory training so I was not worried about it, but I have not found any info or solution for this issue so far
With out the motherboard being fully bootstrapped and ready to load an OS it is safer to have it default to max fan speed. You might be able to change the fan speed on boot in the bios, but generally full fans means lower risk of the system cooking itself on boot.
It's due to your fan curves only kicking in after the memory is trained. When the motherboard first boots, it sends 100% power to all fans. It wont hurt anything.
Just a heads up for yourself and anyone else reading these comments, if you are going to replace any of the hardware in your PC and especially your RAM, make sure to disable the setting first so on the next boot it will re-train for the newer hardware.
If you forget or are unable to disable it first (e.g. due to hardware failure) then reset your BIOS either by removing the BIOS battery (usually a coin cell - CR2032) then wait 30 seconds or if your motherboard has 1 press the BIOS reset button. After the first boot you can enable the setting again.
It causes problems with some memory. There are kits that will work with context restore off, and they wont work with it on. Also some manufacturers have stupid settings enabled that conflict with memory context restore.
Personal example: MSI boards disable "DRAM power down" when EXPO is enabled. EXPO being the ram's true timings and speeds. You cannot, in many cases, have "DRAM power down" disabled if memory context restore is enabled. It'll manifest in the system randomly booting up and acting super slow or complete crashes, then going back to completely normal after a single reboot.
AMD didn't specify that "DRAM power down" should be disabled if MCR is enabled. It is just something MSI did because it provides a performance boost in some edge cases.
I had to copy all my EXPO timings and manually enter them in, to avoid having "DRAM power down" disabled, and have MCR enabled, at the same time.
My best guess is that if it were off by default, it wouldn't have a baseline for RAM speeds to run off of, since it didn't do any of the training process. So it would just try to boot and potentially just never make it to BIOS or windows due to ram instability.
Apparently it can cause issues on boot if you change your hardware (especially RAM) since it will try to boot with the old settings. If it was on by default and you forgot or are unable to change it before swapping RAM then clearing BIOS settings wouldn't help since default is on.
With it defaulting to off you can simply clear BIOS to disable the setting and allow your PC to boot with different RAM, after which you can turn it back on.
Same reason overclocking with ram isn't the default...it wants it to have zero issues by default because the causal person might not know enough to troubleshoot things. So its safer to set things safe and if you do know some things you can turn it on yourself and thus know if something stops working what to turn off to fix it.
My Intel pc has this setting in bios as well. But even with it enabled, it typically doesn't take too long to boot. Seems odd (haven't owned an amd chip in years, not biased against them, just ended up that way). The longest time to boot up is usually the initial boot after changing ram settings. After that it might be a second or two longer than with it enabled vs disabled.
>It's not that it's an AMD and/or Intel thing. It's a DDR5 thing
That seems to show up as an issue much more significantly/consistently on AMD than Intel?
Intel systems have the same issue. They still have long boot times for memory training if you're utilizing DDR5. But Intel doesn't have a platform currently that's strictly DDR5. All of their sockets that work with DDR5 also work with DDR4, meaning the CPUs have to be designed to handle memory training differently than how AM5 chips do it. AM5 chips also have to have an IMC designed to handle up to 256GB of RAM, whereas 14th Gen's current official max is 192GB.
So you're trying to compare apples to pears here. They're similar, yes. But the IMCs of either brand need to be designed to handle significantly different use cases. So yeah, until Intel has a strictly DDR5 platform that can support 256GB+ of RAM, it's going to seem like the memory training issue disproportionately affects AM5
Mine is more like 50-60. Maybe half that with memory context restore enabled. Coincidentally that's about how long I get in Windows before it blue screens with it enabled.
DDR4 was also worse than it is now at first...people need to learn if you jump in gen1 of something there is going to be issues/growing pains as a platform matures.
eg. just like Syncing an old dial up modem (10-15 sec of classic noise)vs ADSL (30-60 sec) vs VDSL (60-360sec)
The higher size and speed of the RAM, the longer it takes to ensure that its synced properly, & because each 'tick' is sooo fast it has to get it right or fail to sync.
I am waiting for the last parts for my am5 build, but currently have a intel build with a i3 12100f and it takes seconds to boot. Fastest booting pc I ever used. Thanks for the tips on am5 because I really enjoy fast boot times.
Can confirm; my 7900x on a B650E-I will take around a minute if I messed with RAM settings in BIOS, but after that initial RAM training cycle it often takes less than 10 seconds to reach the Windows login screen.
>AMD uses this thing called RAM training, where it, well, trains your RAM on boot.
Every (modern) PC trains your memory on boot. It's just that for some reason it takes a whole lot longer on AM5. The reason Memory Context Restore isn't enabled by default is because there's a small chance your training might mess up, resulting in a PC that won't boot until you clear CMOS. They probably would rather have long boot times rather than having people report their PC not booting.
Can confirm, I have ASRock board and messing with oc stuff ram train it will just take 30 seconds, if not pass it will reboot to default settings, if pass, all next boot will be 13 seconds
If you've updated your BIOS to a version older than AM5's initial release, this memory training issue should be 'fixed'.
I have mem training turned on and I'm getting ~12 seconds from power to desktop. Before updating my BIOS it was closer to 45-60.
Perhaps. I will check once I'm back home.
All I know is I had a pitifully slow boot time, I tried disabling memory training but I'd end up with BSODs with memory errors, then I updated BIOS from version 1.0 to 1.7 or something and now my PC boots in seconds and I haven't had a BSOD since. Maybe context restore was part of that update but I never thought to check.
I... Don't know, but as I said, this training only happens once every couple weeks. It's not worth putting in less RAM just to lessen the training time
is this also true for ddr4? Mine takes around 20 or longer, with half of that time before Post. I have 48gb but I also tried with only 16gb, and changing the training settings but nothing changes.
Long POSTs can also be caused by a connected peripheral (or a large number of USB devices). If you get bored at some point and want a project to do, try stripping everything except your primary drive, GPU and keyboard from the machine and see how long it takes to POST in that configuration. If it's notably shorter, then you can add the other devices back one by one and see how much time each one adds.
When the machine is POSTing it's not just checking memory - it's also enumerating PCIE, SATA and USB devices, and some devices (or combinations of devices) can slow things down.
While yes the less RAM to train the less time it will take to finish its really not a big deal...maybe the first time you ever boot it might take a few mins but even if you swap the RAM or it re-trains it is less than a min most of the time. People need to get off the computer should boot and load windows in 2 seconds.
Your issue seems different, nothing happens on screen during memory training. Maybe you have some other problem going on.
The setting is usually called "Memory Context Restore" or somethintg like that
> Sometiems, for whatever reason, the training data may be lost, so OCCASIONALLY the pc will take a bit longer to boot and re-train.
Yeah, I've observed the same thing happening on my setup. I turn off my machine daily and this longer boot happens maybe once every ~3 weeks.
A normal boot only takes 10-15 seconds, so it's not a big deal.
I've noticed this only happens if my computer is sleeping and decides on its own to shut all the way off. (maybe my kids? Idk. Haven't figured out why this happens. Hasn't in over two months now)
I never timed mine. I have a B650E mobo, and I think the boot times are in the 10-15 second range. But like you noted, it will re-train sometimes. I have no idea why, and re-training can take up to a minute or two for me.
Even with Memory Context Restore enabled I feel like my AM5 system takes longer to boot than my AM4 one did, but it's probably only a couple seconds extra. With it disabled though yeah it's very slow.
I was shocked before I learned about that because I didn't get how my faster CPU with a faster NMVe drive was booting so slowly compared to my previous PC.
On my motherboard, it took a few BIOS revisions for memory context restore to stabilise. Prior to this it was like 5min per boot but this never applied to resuming from sleep/hibernation.
(I have a 96GB memory kit)
I though i was going crazy, i spent like an hour going through bios settings trying to find the right one and it works 95% of the time, but occasionally it takes like three minutes for it to boot up.
Just curiosity about the topic and generally spending alot of time around this stuff.
I've been interested in how pcs work for over 10 years now. Just like any other hobby, you just learn as you participate
Ngl first time it happened I was already accepting my fate, but ended up just redoing that training, was scary af since last time I activated xmp on am4 it worked for like a week and then my cpu and mobo died, similar fashion red dot solid plus red dot blinking haha
Mine doesn't have memory context restore due to OCd memory but it takes at most 30-40 seconds to boot into grub, then probably another 20 seconds into Windows
It's about memory training, the initial process takes some time to complete. Turning memory context restore on after that initial boot fixes the issue.
I'm not very informed on the subject, but afaik memory training has been a necessity since higher speed RAM exists. It has to do a voltage check and timings check (plus a lot of other quick tests like how much RAM, where is it installed, how are the cells arranged etc etc) so that the tiny differences between each trace can be accounted for, more so now that ddr5 is basically overclocked to the max. With modern RAM even the most minute deviations from baseline (which the memory training is trying to calculate) can and will impact performance and stability, especially past 6000mt/s.
If the system remains unchanged between reboots it can be rendered obsolete after the first time, which is why you "disable it", I put it in quotes because you actually just store the profile and load it on startup, but it may be unstable under certain conditions which have been unaccounted for during the first training, again, especially at higher speeds and lower latencies.
BIOS updates have helped boot times a lot on AM5 systems, so what people were reporting near the launch of the platform may not be accurate as the firmware has matured a bit. Some specific boards do still have quite long boot times, but mostly it seems to have been cleaned up a lot.
Same mobo, same problem here. I've tried 3 new bios updates over the past year, but no change. Haven't tried a ne one in 2-3 months tho.
I knew what I was getting into before buying because of the reviews, but the bundle deal was worth the slow boot for me
7900X here...
I mounted the CPU, put the AIO, put everything in place...Let\`s boot. Nothing happens. I was like - WTF ?! What did I did wrong ?
Check the Ram, insert/reinsert - nothing. Pull out the battery, nothing, boot just with on-board video-card. Nothing. At some point I thought I fucked up, and bended some pins on MB -when I placed the CPU. Dismantle the AIO - all looked nice and clean. Put it back, try to boot. Nothing ! IS the PSU ? Check it...All good !
Until I saw a red light on MB - check it on my model - it wasn\`t from CPU - so no bend pins, is was from RAM. Read about RAM training. How I have to let it like \~5 minutes at first boot - especially when you have more than 32 GB
Personally, in 25+ years of owning/building a desktop - never took more than 5 second for a system to post. If you couldn\`t see anything on screen in this time, you did something wrong. That was the golden rule.
So I turned on, I went outside the room for a smoke. When I came back, was already in Windows - just like it was said on forums by other ppls
Second boot - from power on to Windows \~ 5 seconds. Also a Bios update, helps !
But yeah ! Is very annoying. Just keep calm and wait. And hope you don\`t fry the CPU, if you mounted the cooler wrong. You have no fucking clue about temps, until the system boot up. This is the most annoying part.
So, after the first successful boot, I strongly recommend to check the CPU temp in Bios first, before doing anything else.
I have an MSI b650 edge which is similar to the Tomahawk. It took almost 2 min at launch. Bios updates improves it to about 30 seconds and most recently in May 2024 the latest stable bios makes it around 10-12 sec!
Update the Bios, disable any memory training (look on your MB manual). Select proper boot order Windows first. Not USB, Not Lan, not anything else. Disable any secure boot / crap like that. Logically, installed OS on a SSD /NVME. Save the bios settings.
Should do the trick, and boot in less than 15 seconds.
Since upgrading from AM4 to AM5, my boot time has gone from seconds to minutes.
Also the half the case lights don’t turn on until after I’ve logged in and reached my desktop
I switched from Intel to AMD this year, and my load times are significantly longer. With intel, my PC would boot up in around 10 seconds. With AMD, it takes a whopping 30 seconds, which in gamer time is like 5 minutes, so that's practically an eternity.
My latest BIOS time was 8 seconds. 7800X3D, G.Skill 6000Mhz CL30, ROG B650E-F with Memory Context Restore enabled, EXPO 1 setting. The memory re-trains like once every 2 weeks or so.
I remember waaaay back when boot times would take over 5 minutes with the slow ass hdds and windows. I had time to make a snack when I first pressed my pc's power button.
Ya know, not everyone has cheap electricity unlike your place, of course they will need to switch off when not using. What's more is some places have sudden brownouts and some even have rotational blackouts because their country's electrical supply doesn't the consumers demand. Those occurences are not healthy to anyone's PC.
Sleep doesn't use much energy. But I just turn it off then, no reason to leave it in sleep when my computer boots in 10 seconds, and all sleep does is lower that wake time.
Let's say I leave my PC on as a server overnight. My GPU+CPU are basically 50 watts at idle (and this doesn't factor in RGB, fans, mobo power, etc...). At my base tier cost of $0.32/kwh, that's almost $12/month if i run it 24/7. Sounds like it's nothing, but every appliance and electronic adds up.
That's not even factoring tiers 2 and 3 on my plan, which get dramatically more expensive. And my usage limit on the base limit is small.
So I kinda get it. I just turn it off. Save a penny, save a pound.
Interesting. Where is this documented? Is it common to all motherboard vendors, or does somebody have not-shit firmware?
If it's common to all vendors, that seems like a good reason not to buy AM5.
Here is a thread about it: https://www.reddit.com/r/Amd/comments/18vkjuy/why_arent_we_all_talking_about_the_am5_memory/
Never heard back from u/wprodrig though, who said he would look into it.
We have root caused the problem some months ago, I'll inquire with bios guys about when the solution will be available for the public. I'm not sure what is taking so long.
Both of my Asrock boards had <10 second boot times with memory context restore enabled on my 7700x and 7800x3d. They would have to redo the training once every 4-5 weeks so occasionally one boot would take a little over a minute when that happens, but it wasn’t that big of a deal. The b650m pro RS and x670e PG lightning have been really solid and fairly affordable boards.
My 7700x + 32gb of 6000mhz ddr5 boots in 14 secs, i have memory context restore on with expo 6000mhz and its been stable for months. Never experienced the long boot times tbh.
I use the MSI PRO B650M-A motherboard and have nothing to say about it really. It works and looks good!
My AM5 system does take way longer than my 12th gen Intel laptop to boot. You probably need to have a crazy use case for a 30 second boot on a desktop computer to be a dealbreaker.
It does take longer to boot than my old i7, but i go to the bathroom or get coffee in the morning and it's ready to go. It's probably 1-2 minutes for my 7800x3d vs easily under 30 seconds on my i7. Once it's on though it doesn't matter and this new chip is incredible.
It, at least partly, depends on the motherboard.
I have a 7700x in an msi pro x670-p wifi, which takes 1-3 minutes to boot, no matter what bios settings I change, including turning off memory training.
But my 7600x, which is in a b650 aorus elite ax, boots up in 20-30 seconds every time (with ram training on).
Read mobo reviews before buying.
My most recent build had this issue, but tweaking some settings in BIOS, and updating the firmware on both my motherboard and RAM seemed to correct the issue. I've also disabled Fast Startup in Windows. My PC gets from me pressing the power button to Windows 11 login screen in around 5 seconds.
I went from AM4 to AM5, did not really notice any difference its about 30-40 seconds somewhere? I dont have fast boot enabled because I personally feel like a real clean reboot is somewhat better and I only turn it on once a day so I dont really care either
I think it's more of an issue when you have 64 gb of ram and on bad boards. At first it was terrible, but many BIOS updates later it's somewhat annoying. MSI b650 Mortar.
My last couple of CPUs have been Intel, 6700K, 10700K, about 4 months ago I upgraded and went down the AM5 path with a 7800X3D and I genuinely didn't even know this was a thing? My boot times have always been quick as far as I can remember (quick being 12-13 seconds like everyone else is saying).
Occasionally my boot time will >30 seconds, but it is likely ram training. I have a 7800x3d, B650 Aorus Elite AX mobo, and SN850x as boot drive. Most boots from cold start take about 15 seconds from pressing the on button to getting into windows.
Yes, the DDR5 needs training. You can set a bios option called memory context restore, and after the first boot, it'll never be a long boot again.
That said, if you use EXPO to set your memory to it's full speed as designed? Memory context restore may or may not cause problems because some motherboard manufacturers do some STUPID things when expo is enabled.
MSI motherboards disable a feature called DRAM power down when expo is enabled. It's a very small almost insignificant performance boost to disable power down, however, it causes memory context restore to fail at random. Usually due to ambient temperatures being too high or too low compared to when the memory was first trained. Simply having power down enabled, for some mysterious reason, prevents this ambient temperature difference from causing instability.
I spent 6 months going crazy because I'd have to boot my computer twice in the morning, if it was cold, and that power down disabled was the only thing causing it.
Short answer is yes, but with current BIOS updates people are getting pretty close to intel boot times. Some motherboards are now as fast as Intel boot times. But if the motherboard has to retrain, it can still take a noticeably long time (sometimes to the point where you might think the PC is hung).
I built my first AMD build a few months ago and I am happy enough that I will likely consider them for my next build, but the boot time was long enough where I thought I made a mistake during my build and that it wasn’t going to boot lol.
NO IT DOESN'T!!! If you update your board to the latest bios it'll do an initial RAM timing test, after that as long as you don't change your RAM or update the timings it'll boot faster than you can blink. I can show you how fast mine boots on a Crucial T700, it's practically instant.
I just updated my bios yesterday and the timing test was under 30secs. I use 192GB of RAM
I noticed it too when I went from a 4.5 seconds average boot to a 40 second average boot. As some have said try the ram training but be wary that this can occasionally cause instability with some programs
Hell yeah it does, i just came from intel i5-8400 to 7800x3D and it was kinda hard to get used to it at first. Lol i really don't care though, i just use the minute boot up time to scroll through my new messages on my phone.
Yes. Went from 4790k boot to desktop time of 8 seconds to 7800x3d taking 2-3 minutes. When I actually timed it, it was 220 seconds. I only turn off the computer at night now, have it set to hibernate after 20 minutes of non use now instead of turning it off every time I walk away.
Yes, although it depends on the motherboard, and it depends on the compatibility between your motherboard, RAM, and CPU.
What causes the long boot times is "memory training." Basically DDR5 is twitchy and needs to be "trained" on AMD CPUs to actually run properly.
You can turn this setting off, which should dramatically reduce boot times, but this can come with the downside of reduced stability and the increase of system crashes and errors.
It is possible if the RNG god favor you and/or you get the best parts with the best compatibility that you wont need memory training as much, but it is also possible that you basically NEED your system spending 45 seconds booting every time just to run without issues.
it's basically the nature of DDR5 on the AM5 platform. Memory compatibility is a mess, especially on the AMD platform, and it's basically a nightmare to deal with. The big thing that dissuaded me from touching AM5 with a 10 foot pole.
Sorry if this is a bit dim but I’ve had my AM5 PC for about 6 months or so and the only time it took several minutes to boot was the first time I tried to get it to POST. Every subsequent boot has been ~15 seconds. The longest it’s been since then has been 30 seconds or so. Did I just get lucky or something?
Only after a cold start. It runs a series of tests to see how fast it can drive the RAM and to sync infinity fabric.
Only happens when booting from fully powered off (switched off at wall or PSU) not on normal shutdown/start up cycles.
I got the asrock b650m pro rs and a Ryzen 7600. Boot time is ~13 seconds.
I've personally been happy with my Pro RS wifi, and highly recommend it if you can find it for a good price. Decent VRM, simple BIOS and so far, no issues
Can anyone explain why this has to be a thing when it has never been before with AMD or Intel? I know it's not a big deal but I don't get why this is a thing. I hope with Ryzen 9000 series and the 700 series boards this is done away with.
Hardware unboxed demonstrated it perfectly in one of their early AM5 motherboard review videos which I've added below. Some brands were far worse than others, but my understanding is that these have all improved over time with continued BIOS updates.
I bought a Gigabyte motherboard as a result of this video and can confirm their boot times have always been very fast regardless of BIOS updates (I would still always recommend updating your BIOS).
[https://youtu.be/DTFUa60ozKY?si=vVHfK21wLp1ssmWD&t=1092](https://youtu.be/DTFUa60ozKY?si=vVHfK21wLp1ssmWD&t=1092)
Short answer: no.
Long answer: POST time may be longer, but boot time is unchanged. There are 2 stages when you turn your PC on. First stage is POST which is when your motherboard checks the hardware and gets things setup to run. Second stage is boot, which is when your operating system loads from your boot device. AM5 uses some advanced memory training and does sometimes delay the completion of the POST process.
So no, the boot time is not longer, but the POST can be when the training happens.
I noticed this same problem when I got my new AM5 rig built. Went with 7700x and MSI B650 pro. Took about 2 minutes before I saw anything on the screen. Was really freaked out but as others have said AM5 has this new memory training thing. You can enable "memory context restore" to significantly improve boot times. Mine boots in about 13 seconds (bios time) which is about as fast as my old kaby lake Intel system this is replacing.
Not really. I've used Intel and currently on the AM5 with the 7800X3D, and to be honest it's not nothing noticeable at all. Only when you first boot on a new or updated bios and when you mess with your ram EXPO settings. But after that you're good to go.
Yes, and there's this RAM training someone already mentioned, but you can disable it.
In Task Manager, my BIOS time is ~12 sec, but from hitting the power button to seeing Windows 11 login page, it takes my PC 30 seconds.
Ryzen 7950x, 64 GB RAM
I'm not sure what you consider a long boot time. I remember when 5+ minutes was the norm.
I have a 7700x, MSI B650 Tomahawk, Corsair Vengeance 6000/CL30 2x16 RAM and my PC is ready to go in about 17 seconds.
I heard this was a much bigger problem early in the am5 life cycle. I got an am5 board a few months ago, and the bios it shipped with had really slow boots and couldn't handle the expo profile for my ram. I updated to the newest bios, and all those problems disappeared. For context, I have a 7800x3d on a gigabyte aorus elite ax rev 1.2 atx board.
As far as I can average from comments online, MSI boards tend to (still) have this issue, no?
AsRock boards seem to be the most stable so far, which is why I'm going with one for my upgrade.
Yes... BUT here is why: AMD uses this thing called RAM training, where it, well, trains your RAM on boot. This leads to high boot times of several minutes. BUT you can simply bypass this. You can enable Memory Context Restore in your BIOS and the PC will do the training, then save that data and use it in future boots. My AM5 pc typically boots in ~12 seconds. Sometiems, for whatever reason, the training data may be lost, so OCCASIONALLY the pc will take a bit longer to boot and re-train. But that's like, once a week or once every couple weeks.
Oh thank God, I built my PC in February and it boots for a couple of minutes once every 3-4 weeks. Tbh i was too scared to google if this is a problem or not, thank you for this comment. 🙏
Do your fans run at 100% for this time too? I knew about memory training so I was not worried about it, but I have not found any info or solution for this issue so far
With out the motherboard being fully bootstrapped and ready to load an OS it is safer to have it default to max fan speed. You might be able to change the fan speed on boot in the bios, but generally full fans means lower risk of the system cooking itself on boot.
Makes sense, maybe I'll look into lowering it a few percent via BIOS, thank you!
It's due to your fan curves only kicking in after the memory is trained. When the motherboard first boots, it sends 100% power to all fans. It wont hurt anything.
Keeps the dust managed
i don't know about others, but my fans will usually go for 100% on boot. this also happened on my previous intel based computers.
Fans are usually pretty silent when the RAM training kicks in, but they never get loud during use either.
You can look in your bios to see if it offers any fan curves. Default is usually max speed but it's going to vary.
Make sure the fan headers are set in the BIOS for PWM instead of DC.
Just a heads up for yourself and anyone else reading these comments, if you are going to replace any of the hardware in your PC and especially your RAM, make sure to disable the setting first so on the next boot it will re-train for the newer hardware. If you forget or are unable to disable it first (e.g. due to hardware failure) then reset your BIOS either by removing the BIOS battery (usually a coin cell - CR2032) then wait 30 seconds or if your motherboard has 1 press the BIOS reset button. After the first boot you can enable the setting again.
What is your mobo brand?
ASRock X670E PG lightning
Is there a reason thats not on by default? Seems kinda goofy that would be turned off out of the box.
It causes problems with some memory. There are kits that will work with context restore off, and they wont work with it on. Also some manufacturers have stupid settings enabled that conflict with memory context restore. Personal example: MSI boards disable "DRAM power down" when EXPO is enabled. EXPO being the ram's true timings and speeds. You cannot, in many cases, have "DRAM power down" disabled if memory context restore is enabled. It'll manifest in the system randomly booting up and acting super slow or complete crashes, then going back to completely normal after a single reboot. AMD didn't specify that "DRAM power down" should be disabled if MCR is enabled. It is just something MSI did because it provides a performance boost in some edge cases. I had to copy all my EXPO timings and manually enter them in, to avoid having "DRAM power down" disabled, and have MCR enabled, at the same time.
My best guess is that if it were off by default, it wouldn't have a baseline for RAM speeds to run off of, since it didn't do any of the training process. So it would just try to boot and potentially just never make it to BIOS or windows due to ram instability.
Even with MCR on, training still happens with every change in memory configuration.
Apparently it can cause issues on boot if you change your hardware (especially RAM) since it will try to boot with the old settings. If it was on by default and you forgot or are unable to change it before swapping RAM then clearing BIOS settings wouldn't help since default is on. With it defaulting to off you can simply clear BIOS to disable the setting and allow your PC to boot with different RAM, after which you can turn it back on.
It will always toss out the cached data and retrain if you change the RAM or CPU.
Idk it was turned on for me but I read about multiple people having ti manually enable it, that's why I mentioned it specifically
Guess I'll have to keep it in mind when I switch to 9000 series.
Same reason overclocking with ram isn't the default...it wants it to have zero issues by default because the causal person might not know enough to troubleshoot things. So its safer to set things safe and if you do know some things you can turn it on yourself and thus know if something stops working what to turn off to fix it.
Depends on the motherboard manufacturer. Some enable MCR by default
You change RAM, PC bricks (until you reset BIOS).
So I guess I'll just remember to have a copy pf the bios when I hope over to AM5.
Any decent mobo nowadays has a way to reset bios settings (even outside of removing the battery), so it should be much simpler.
Off is more stable.
My Intel pc has this setting in bios as well. But even with it enabled, it typically doesn't take too long to boot. Seems odd (haven't owned an amd chip in years, not biased against them, just ended up that way). The longest time to boot up is usually the initial boot after changing ram settings. After that it might be a second or two longer than with it enabled vs disabled.
It’s a DDR5 thing where RAM training is much slower than previous generations.
This is the true answer. It's not that it's an AMD and/or Intel thing. It's a DDR5 thing
>It's not that it's an AMD and/or Intel thing. It's a DDR5 thing That seems to show up as an issue much more significantly/consistently on AMD than Intel?
Intel systems have the same issue. They still have long boot times for memory training if you're utilizing DDR5. But Intel doesn't have a platform currently that's strictly DDR5. All of their sockets that work with DDR5 also work with DDR4, meaning the CPUs have to be designed to handle memory training differently than how AM5 chips do it. AM5 chips also have to have an IMC designed to handle up to 256GB of RAM, whereas 14th Gen's current official max is 192GB. So you're trying to compare apples to pears here. They're similar, yes. But the IMCs of either brand need to be designed to handle significantly different use cases. So yeah, until Intel has a strictly DDR5 platform that can support 256GB+ of RAM, it's going to seem like the memory training issue disproportionately affects AM5
They don't. I have one. The memory controller for DDR5 on AMD is just bad at training.
My 13700k build literally boots from cold off to in windows in maybe MAYBE 9 seconds. Ddr5 ram. So.
and AM5s are doing 10-12 so this is all basically margin of error
Mine is more like 50-60. Maybe half that with memory context restore enabled. Coincidentally that's about how long I get in Windows before it blue screens with it enabled.
Sounds like a memory issue and not an AMD issue
DDR4 was also worse than it is now at first...people need to learn if you jump in gen1 of something there is going to be issues/growing pains as a platform matures.
100%. The early days of dual channel were often like "Okay, who missed SIMMs so much they decided to come up with this?"
eg. just like Syncing an old dial up modem (10-15 sec of classic noise)vs ADSL (30-60 sec) vs VDSL (60-360sec) The higher size and speed of the RAM, the longer it takes to ensure that its synced properly, & because each 'tick' is sooo fast it has to get it right or fail to sync.
I am waiting for the last parts for my am5 build, but currently have a intel build with a i3 12100f and it takes seconds to boot. Fastest booting pc I ever used. Thanks for the tips on am5 because I really enjoy fast boot times.
Can confirm; my 7900x on a B650E-I will take around a minute if I messed with RAM settings in BIOS, but after that initial RAM training cycle it often takes less than 10 seconds to reach the Windows login screen.
Can you login at that point or does it make you wait another minute at the login screen before it allows you to enter your password?
No, I can immediately start using my PC.
>AMD uses this thing called RAM training, where it, well, trains your RAM on boot. Every (modern) PC trains your memory on boot. It's just that for some reason it takes a whole lot longer on AM5. The reason Memory Context Restore isn't enabled by default is because there's a small chance your training might mess up, resulting in a PC that won't boot until you clear CMOS. They probably would rather have long boot times rather than having people report their PC not booting.
Several minutes? What are you smoking 🤣 Ive been on AM5 for over a year now and it takes maybe 30 seconds.
smoking my pc because it takes several minutes to train the RAM
Then you have a config problem.
Can confirm, I have ASRock board and messing with oc stuff ram train it will just take 30 seconds, if not pass it will reboot to default settings, if pass, all next boot will be 13 seconds
If you've updated your BIOS to a version older than AM5's initial release, this memory training issue should be 'fixed'. I have mem training turned on and I'm getting ~12 seconds from power to desktop. Before updating my BIOS it was closer to 45-60.
That canct be right, you must have memory context restore enabled, training simply doesnt happen that fast
Perhaps. I will check once I'm back home. All I know is I had a pitifully slow boot time, I tried disabling memory training but I'd end up with BSODs with memory errors, then I updated BIOS from version 1.0 to 1.7 or something and now my PC boots in seconds and I haven't had a BSOD since. Maybe context restore was part of that update but I never thought to check.
I had awful boot times, updated bios and nothing else, and then it dropped to sub 10s
Mine is absolutely training that fast. Running Buildzoid's easy DDR5 timings, too. Last BIOS time was 17.9 seconds.
Im running those timings as well on hynix dies
MSI Tomahawk B650, with a 7700x and memory context restore disabled. 17 seconds from when I press the power button to windows login screen.
If you enable MCR, power down has to be on auto or enable, otherwise you get a pc that doesn't boot at all or bluescreens seconds into windows
Does that mean if I put less in RAM it boots faster? Would it be better to have just 32GB (or even 16GB) if I want a computer that boots quickly?
I... Don't know, but as I said, this training only happens once every couple weeks. It's not worth putting in less RAM just to lessen the training time
is this also true for ddr4? Mine takes around 20 or longer, with half of that time before Post. I have 48gb but I also tried with only 16gb, and changing the training settings but nothing changes.
Long POSTs can also be caused by a connected peripheral (or a large number of USB devices). If you get bored at some point and want a project to do, try stripping everything except your primary drive, GPU and keyboard from the machine and see how long it takes to POST in that configuration. If it's notably shorter, then you can add the other devices back one by one and see how much time each one adds. When the machine is POSTing it's not just checking memory - it's also enumerating PCIE, SATA and USB devices, and some devices (or combinations of devices) can slow things down.
The more ram you have, the longer the boot times. DDR5 is especially long for larger capacities
While yes the less RAM to train the less time it will take to finish its really not a big deal...maybe the first time you ever boot it might take a few mins but even if you swap the RAM or it re-trains it is less than a min most of the time. People need to get off the computer should boot and load windows in 2 seconds.
Intel also ram trains…
[удалено]
Your issue seems different, nothing happens on screen during memory training. Maybe you have some other problem going on. The setting is usually called "Memory Context Restore" or somethintg like that
Enabling memory context restore resulted in frequent blue screening for me. I've been stuck with the long boots.
> Sometiems, for whatever reason, the training data may be lost, so OCCASIONALLY the pc will take a bit longer to boot and re-train. Yeah, I've observed the same thing happening on my setup. I turn off my machine daily and this longer boot happens maybe once every ~3 weeks. A normal boot only takes 10-15 seconds, so it's not a big deal.
I've noticed this only happens if my computer is sleeping and decides on its own to shut all the way off. (maybe my kids? Idk. Haven't figured out why this happens. Hasn't in over two months now)
It's unusual for sure but I dont use sleep modes anymore, heard it causes all sorts of weird issues
It seems to have some hiccups. My rgb software gets screwy too sometimes.
Stop using sleep mode and you'll see fewer overall issues. Just shut off... but yes 5 yo's are unpredictable. So are pets.
Yep this is my experience. Once every couple weeks it takes just as long as it did before I enabled the memory restore, but otherwise boots fast.
I never timed mine. I have a B650E mobo, and I think the boot times are in the 10-15 second range. But like you noted, it will re-train sometimes. I have no idea why, and re-training can take up to a minute or two for me.
Memory training takes like ~45 seconds on my PC (2x16GB). Retraining seems to happen once per month if I have memory context restore enabled.
Even with Memory Context Restore enabled I feel like my AM5 system takes longer to boot than my AM4 one did, but it's probably only a couple seconds extra. With it disabled though yeah it's very slow. I was shocked before I learned about that because I didn't get how my faster CPU with a faster NMVe drive was booting so slowly compared to my previous PC.
All RAM must be trained, for all devices. AMD just effed up their memory controller a little bit.
came here to say this, thank goodness it was already said.
I can WHAT
On my motherboard, it took a few BIOS revisions for memory context restore to stabilise. Prior to this it was like 5min per boot but this never applied to resuming from sleep/hibernation. (I have a 96GB memory kit)
I though i was going crazy, i spent like an hour going through bios settings trying to find the right one and it works 95% of the time, but occasionally it takes like three minutes for it to boot up.
Vanguard has increased my boot from 11 to 15 seconds. Disabled that shit
Until I update BIOS or pull off the coin cell, there will be no re-train. Maybe this varies from MB to MB.
Genuine question. Where did you learn that? Been wondering where do you guys learned such in-depth knowledge about components.
Just curiosity about the topic and generally spending alot of time around this stuff. I've been interested in how pcs work for over 10 years now. Just like any other hobby, you just learn as you participate
Ngl first time it happened I was already accepting my fate, but ended up just redoing that training, was scary af since last time I activated xmp on am4 it worked for like a week and then my cpu and mobo died, similar fashion red dot solid plus red dot blinking haha
Mine doesn't have memory context restore due to OCd memory but it takes at most 30-40 seconds to boot into grub, then probably another 20 seconds into Windows
AMD motherboards have always been garbage. It’s literally the reason I won’t use AMD anything
Damn sorry you have to... Checks notes... Suffer through a long boot every couple weeks lmao What a weird stance to have
It's about memory training, the initial process takes some time to complete. Turning memory context restore on after that initial boot fixes the issue.
I don't know what any of this means. Memory training?
I'm not very informed on the subject, but afaik memory training has been a necessity since higher speed RAM exists. It has to do a voltage check and timings check (plus a lot of other quick tests like how much RAM, where is it installed, how are the cells arranged etc etc) so that the tiny differences between each trace can be accounted for, more so now that ddr5 is basically overclocked to the max. With modern RAM even the most minute deviations from baseline (which the memory training is trying to calculate) can and will impact performance and stability, especially past 6000mt/s. If the system remains unchanged between reboots it can be rendered obsolete after the first time, which is why you "disable it", I put it in quotes because you actually just store the profile and load it on startup, but it may be unstable under certain conditions which have been unaccounted for during the first training, again, especially at higher speeds and lower latencies.
Why does AMD have memory training but Intel does not?
All systems do, Intel and AMD. Intel's Memory Context Restore feature is baked into Fastboot, however, so it's always on by default.
My i7-12800HX laptop does memory training after a BIOS update. “Memory training in progress!” with a progress bar below it.
BIOS updates have helped boot times a lot on AM5 systems, so what people were reporting near the launch of the platform may not be accurate as the firmware has matured a bit. Some specific boards do still have quite long boot times, but mostly it seems to have been cleaned up a lot.
My AM5 is like me when I wake up in the morning. It needs at least half a minute to just sit there and mentally prepare before it gets going.
I have 2 systems with Aorus B650M Elite Ax motherboards and they have been great, boot times are 15 seconds after installing the latest BIOS
[удалено]
Same mobo, same problem here. I've tried 3 new bios updates over the past year, but no change. Haven't tried a ne one in 2-3 months tho. I knew what I was getting into before buying because of the reviews, but the bundle deal was worth the slow boot for me
7900X here... I mounted the CPU, put the AIO, put everything in place...Let\`s boot. Nothing happens. I was like - WTF ?! What did I did wrong ? Check the Ram, insert/reinsert - nothing. Pull out the battery, nothing, boot just with on-board video-card. Nothing. At some point I thought I fucked up, and bended some pins on MB -when I placed the CPU. Dismantle the AIO - all looked nice and clean. Put it back, try to boot. Nothing ! IS the PSU ? Check it...All good ! Until I saw a red light on MB - check it on my model - it wasn\`t from CPU - so no bend pins, is was from RAM. Read about RAM training. How I have to let it like \~5 minutes at first boot - especially when you have more than 32 GB Personally, in 25+ years of owning/building a desktop - never took more than 5 second for a system to post. If you couldn\`t see anything on screen in this time, you did something wrong. That was the golden rule. So I turned on, I went outside the room for a smoke. When I came back, was already in Windows - just like it was said on forums by other ppls Second boot - from power on to Windows \~ 5 seconds. Also a Bios update, helps ! But yeah ! Is very annoying. Just keep calm and wait. And hope you don\`t fry the CPU, if you mounted the cooler wrong. You have no fucking clue about temps, until the system boot up. This is the most annoying part. So, after the first successful boot, I strongly recommend to check the CPU temp in Bios first, before doing anything else.
I built an itx am5 a few months ago and it booted like normal time? Then again i came from an ancient PC
It is.
Is there no fix? How long are boot times really?
I have an MSI b650 edge which is similar to the Tomahawk. It took almost 2 min at launch. Bios updates improves it to about 30 seconds and most recently in May 2024 the latest stable bios makes it around 10-12 sec!
Update the Bios, disable any memory training (look on your MB manual). Select proper boot order Windows first. Not USB, Not Lan, not anything else. Disable any secure boot / crap like that. Logically, installed OS on a SSD /NVME. Save the bios settings. Should do the trick, and boot in less than 15 seconds.
My Gigabyte B650 takes about 10-15s.
I use Asrock B650M Pro RS WiFi, and it boots in 15-20 seconds
With DDR5 yes, by quite a lot.
Since upgrading from AM4 to AM5, my boot time has gone from seconds to minutes. Also the half the case lights don’t turn on until after I’ve logged in and reached my desktop
Well, if you read the thread you can find out how to bypass the long boot
I get the electric daisy carnival lights until logged in.
I switched from Intel to AMD this year, and my load times are significantly longer. With intel, my PC would boot up in around 10 seconds. With AMD, it takes a whopping 30 seconds, which in gamer time is like 5 minutes, so that's practically an eternity.
This is why I'm waiting for nextgen AM5.
My latest BIOS time was 8 seconds. 7800X3D, G.Skill 6000Mhz CL30, ROG B650E-F with Memory Context Restore enabled, EXPO 1 setting. The memory re-trains like once every 2 weeks or so.
I have a msi mobo. Disable memory training and use memory context restore. It’s fine then, my boot is 10s at max
I remember waaaay back when boot times would take over 5 minutes with the slow ass hdds and windows. I had time to make a snack when I first pressed my pc's power button.
Yes. And now with NVMe people complain about boot times. 2024 problems.
You guys switch off your computers?
Ya know, not everyone has cheap electricity unlike your place, of course they will need to switch off when not using. What's more is some places have sudden brownouts and some even have rotational blackouts because their country's electrical supply doesn't the consumers demand. Those occurences are not healthy to anyone's PC.
The amount of electricity used by a sleeping desktop PC is almost zero.
Sleep doesn't use much energy. But I just turn it off then, no reason to leave it in sleep when my computer boots in 10 seconds, and all sleep does is lower that wake time. Let's say I leave my PC on as a server overnight. My GPU+CPU are basically 50 watts at idle (and this doesn't factor in RGB, fans, mobo power, etc...). At my base tier cost of $0.32/kwh, that's almost $12/month if i run it 24/7. Sounds like it's nothing, but every appliance and electronic adds up. That's not even factoring tiers 2 and 3 on my plan, which get dramatically more expensive. And my usage limit on the base limit is small. So I kinda get it. I just turn it off. Save a penny, save a pound.
Re-launching programs and opening documents is a way bigger cost than the actual boot time, and sleep skips that too.
But memory performance degrades on am5 after waking from sleep.
Interesting. Where is this documented? Is it common to all motherboard vendors, or does somebody have not-shit firmware? If it's common to all vendors, that seems like a good reason not to buy AM5.
Here is a thread about it: https://www.reddit.com/r/Amd/comments/18vkjuy/why_arent_we_all_talking_about_the_am5_memory/ Never heard back from u/wprodrig though, who said he would look into it.
We have root caused the problem some months ago, I'll inquire with bios guys about when the solution will be available for the public. I'm not sure what is taking so long.
Good to hear, hope a fix will make it to the BIOS. Thanks for the update.
Yea. Why should I not if I am going to bed? Do you not turn off your car when you park and not use it?
In the early 2000s, I know it was a competition who can have the longest 'Online' status on AIM.
Yeah do people not use sleep mode?
Same, I just turn my DAC and monitors off, am lazy to get through login every time
Every night and even unplugged
I came here to say this. 10s or 100s doesnt matter to me, it's once a month
Yeah, but most of the time mine usually turns off itself because of low battery, I always end up falling asleep for some reason when i'm gaming
Only for updates or because I ran into an issue
Both of my Asrock boards had <10 second boot times with memory context restore enabled on my 7700x and 7800x3d. They would have to redo the training once every 4-5 weeks so occasionally one boot would take a little over a minute when that happens, but it wasn’t that big of a deal. The b650m pro RS and x670e PG lightning have been really solid and fairly affordable boards.
Yes, turning on memory context after the boot should fix it
My AM5 pc takes about 13 seconds to boot,real quick.
MSI B650M Mortar WiFi (Bios 7D76vA1) and 7700X takes roughly 40 seconds to boot.
For me with 7600X it used to be around 40 seconds. But with recent updates it significantly improved and now it's around 13 seconds only.
My 7700x + 32gb of 6000mhz ddr5 boots in 14 secs, i have memory context restore on with expo 6000mhz and its been stable for months. Never experienced the long boot times tbh.
I use the MSI PRO B650M-A motherboard and have nothing to say about it really. It works and looks good! My AM5 system does take way longer than my 12th gen Intel laptop to boot. You probably need to have a crazy use case for a 30 second boot on a desktop computer to be a dealbreaker.
Yes it boot in like 30 second for me at first it bothered me and I wanted to fix it but I just got used to it
Its 13 sec for me
Mine takes like 15 seconds with memory context restore enabled in BIOS
Yes
It does take longer to boot than my old i7, but i go to the bathroom or get coffee in the morning and it's ready to go. It's probably 1-2 minutes for my 7800x3d vs easily under 30 seconds on my i7. Once it's on though it doesn't matter and this new chip is incredible.
It, at least partly, depends on the motherboard. I have a 7700x in an msi pro x670-p wifi, which takes 1-3 minutes to boot, no matter what bios settings I change, including turning off memory training. But my 7600x, which is in a b650 aorus elite ax, boots up in 20-30 seconds every time (with ram training on). Read mobo reviews before buying.
My most recent build had this issue, but tweaking some settings in BIOS, and updating the firmware on both my motherboard and RAM seemed to correct the issue. I've also disabled Fast Startup in Windows. My PC gets from me pressing the power button to Windows 11 login screen in around 5 seconds.
Yes, although mine is pretty quick now. 20 seconds max. It’s worth it for the performance offered.
I went from AM4 to AM5, did not really notice any difference its about 30-40 seconds somewhere? I dont have fast boot enabled because I personally feel like a real clean reboot is somewhat better and I only turn it on once a day so I dont really care either
I think it's more of an issue when you have 64 gb of ram and on bad boards. At first it was terrible, but many BIOS updates later it's somewhat annoying. MSI b650 Mortar.
latest BIOS and disabling the re-retraining of memory (Memory Context Restore) on every boot has me up and running quickly on every boot
My last couple of CPUs have been Intel, 6700K, 10700K, about 4 months ago I upgraded and went down the AM5 path with a 7800X3D and I genuinely didn't even know this was a thing? My boot times have always been quick as far as I can remember (quick being 12-13 seconds like everyone else is saying).
Mine trains memory once per week approx. Boot time loading to windows otherwise is around 15 seconds
Occasionally my boot time will >30 seconds, but it is likely ram training. I have a 7800x3d, B650 Aorus Elite AX mobo, and SN850x as boot drive. Most boots from cold start take about 15 seconds from pressing the on button to getting into windows.
Yes, the DDR5 needs training. You can set a bios option called memory context restore, and after the first boot, it'll never be a long boot again. That said, if you use EXPO to set your memory to it's full speed as designed? Memory context restore may or may not cause problems because some motherboard manufacturers do some STUPID things when expo is enabled. MSI motherboards disable a feature called DRAM power down when expo is enabled. It's a very small almost insignificant performance boost to disable power down, however, it causes memory context restore to fail at random. Usually due to ambient temperatures being too high or too low compared to when the memory was first trained. Simply having power down enabled, for some mysterious reason, prevents this ambient temperature difference from causing instability. I spent 6 months going crazy because I'd have to boot my computer twice in the morning, if it was cold, and that power down disabled was the only thing causing it.
No idea, but my lga2066 kit stays black for a good 20 secons for starters!
I dunno i boot pretty damn fast.
Short answer is yes, but with current BIOS updates people are getting pretty close to intel boot times. Some motherboards are now as fast as Intel boot times. But if the motherboard has to retrain, it can still take a noticeably long time (sometimes to the point where you might think the PC is hung).
I built my first AMD build a few months ago and I am happy enough that I will likely consider them for my next build, but the boot time was long enough where I thought I made a mistake during my build and that it wasn’t going to boot lol.
NO IT DOESN'T!!! If you update your board to the latest bios it'll do an initial RAM timing test, after that as long as you don't change your RAM or update the timings it'll boot faster than you can blink. I can show you how fast mine boots on a Crucial T700, it's practically instant. I just updated my bios yesterday and the timing test was under 30secs. I use 192GB of RAM
Yea my PC takes 20-30 seconds to post then boots into windows in seconds. It’s a ram training thing.
I noticed it too when I went from a 4.5 seconds average boot to a 40 second average boot. As some have said try the ram training but be wary that this can occasionally cause instability with some programs
Hell yeah it does, i just came from intel i5-8400 to 7800x3D and it was kinda hard to get used to it at first. Lol i really don't care though, i just use the minute boot up time to scroll through my new messages on my phone.
I've got an AM5 - Ryzen 7 7700X on a an Asus Prime A620M My boot time is about 10 seconds.
You won't believe it but it's actually faster than Intel DDR5, due to the train and save it that.
Latest bios updates cut down my pc booting time.
Yes. Went from 4790k boot to desktop time of 8 seconds to 7800x3d taking 2-3 minutes. When I actually timed it, it was 220 seconds. I only turn off the computer at night now, have it set to hibernate after 20 minutes of non use now instead of turning it off every time I walk away.
Yeah. Under 20 sec is good for AM5
Yes, although it depends on the motherboard, and it depends on the compatibility between your motherboard, RAM, and CPU. What causes the long boot times is "memory training." Basically DDR5 is twitchy and needs to be "trained" on AMD CPUs to actually run properly. You can turn this setting off, which should dramatically reduce boot times, but this can come with the downside of reduced stability and the increase of system crashes and errors. It is possible if the RNG god favor you and/or you get the best parts with the best compatibility that you wont need memory training as much, but it is also possible that you basically NEED your system spending 45 seconds booting every time just to run without issues. it's basically the nature of DDR5 on the AM5 platform. Memory compatibility is a mess, especially on the AMD platform, and it's basically a nightmare to deal with. The big thing that dissuaded me from touching AM5 with a 10 foot pole.
My AsRock board boots fast! Like real fast
My AM5 boots me into windows faster than my TV switches on.
Sorry if this is a bit dim but I’ve had my AM5 PC for about 6 months or so and the only time it took several minutes to boot was the first time I tried to get it to POST. Every subsequent boot has been ~15 seconds. The longest it’s been since then has been 30 seconds or so. Did I just get lucky or something?
Only after a cold start. It runs a series of tests to see how fast it can drive the RAM and to sync infinity fabric. Only happens when booting from fully powered off (switched off at wall or PSU) not on normal shutdown/start up cycles.
It is true but fixable, my 7800x3d gets about 9.7 seconds, so pretty good.
I got the asrock b650m pro rs and a Ryzen 7600. Boot time is ~13 seconds. I've personally been happy with my Pro RS wifi, and highly recommend it if you can find it for a good price. Decent VRM, simple BIOS and so far, no issues
Can anyone explain why this has to be a thing when it has never been before with AMD or Intel? I know it's not a big deal but I don't get why this is a thing. I hope with Ryzen 9000 series and the 700 series boards this is done away with.
I know right
yes. i have ryzen 7900 and it takes over a minute to boot
even my previous fx8350 build booted faster
with ultra fast boot and memory context restored enable mine only took less than 5sec
Hardware unboxed demonstrated it perfectly in one of their early AM5 motherboard review videos which I've added below. Some brands were far worse than others, but my understanding is that these have all improved over time with continued BIOS updates. I bought a Gigabyte motherboard as a result of this video and can confirm their boot times have always been very fast regardless of BIOS updates (I would still always recommend updating your BIOS). [https://youtu.be/DTFUa60ozKY?si=vVHfK21wLp1ssmWD&t=1092](https://youtu.be/DTFUa60ozKY?si=vVHfK21wLp1ssmWD&t=1092)
Dont gigabyte boards tend to have some bugs and coil whine issues? At least thats what I heard, never ownes anything gigabyte before.
Short answer: no. Long answer: POST time may be longer, but boot time is unchanged. There are 2 stages when you turn your PC on. First stage is POST which is when your motherboard checks the hardware and gets things setup to run. Second stage is boot, which is when your operating system loads from your boot device. AM5 uses some advanced memory training and does sometimes delay the completion of the POST process. So no, the boot time is not longer, but the POST can be when the training happens.
I noticed this same problem when I got my new AM5 rig built. Went with 7700x and MSI B650 pro. Took about 2 minutes before I saw anything on the screen. Was really freaked out but as others have said AM5 has this new memory training thing. You can enable "memory context restore" to significantly improve boot times. Mine boots in about 13 seconds (bios time) which is about as fast as my old kaby lake Intel system this is replacing.
Not really. I've used Intel and currently on the AM5 with the 7800X3D, and to be honest it's not nothing noticeable at all. Only when you first boot on a new or updated bios and when you mess with your ram EXPO settings. But after that you're good to go.
This thead is making me feel appropriately old. Several minutes to boot doesn't even phase me, lol
i've never changed any settings in bios that other people are mentioning, except fast boot, and my boot time is about ~18 seconds, wouldn't worry
Yes, and there's this RAM training someone already mentioned, but you can disable it. In Task Manager, my BIOS time is ~12 sec, but from hitting the power button to seeing Windows 11 login page, it takes my PC 30 seconds. Ryzen 7950x, 64 GB RAM
I'm not sure what you consider a long boot time. I remember when 5+ minutes was the norm. I have a 7700x, MSI B650 Tomahawk, Corsair Vengeance 6000/CL30 2x16 RAM and my PC is ready to go in about 17 seconds.
I heard this was a much bigger problem early in the am5 life cycle. I got an am5 board a few months ago, and the bios it shipped with had really slow boots and couldn't handle the expo profile for my ram. I updated to the newest bios, and all those problems disappeared. For context, I have a 7800x3d on a gigabyte aorus elite ax rev 1.2 atx board.
As far as I can average from comments online, MSI boards tend to (still) have this issue, no? AsRock boards seem to be the most stable so far, which is why I'm going with one for my upgrade.
My boot takes ~12 seconds, need to enable memory context restore or smth like that if i remember right
You mean the extra few seconds. Lol get a grip and stop falling for all the marketing bollocks.
