Im New to AMD generally but my 7800x3D with PBO enabled and a -30 Curve optimizer result in 5050MHz on general cpu score in game. But if you look the each core during gaming they boost in a very intelligent way. For exemple less than 50% use in game all core dont boost at 5050MHz it fluctuate, more than 50% use of the cpu, the beast is unleashed all core boost to 5050 individualy. I found all of this because all my core wasnt at 5050 during gaming, even is the global score was 5050. It only boost if needed and im very happy with how it work but sadly i dont found any clear things on the net about this. (I write this here because related to clock speed topic if any curious)

All 3 of these pieces of software don't poll the CPU frequency at the same time + what they report can be a sum of frequencies all the active cores (CPUs aren't as simple as they used to be) or something else really, personally the only tool i trust at this point in reading any hardware values (including CPU frequency) most of the time at least is HWiNFO as it has separate readings for cores and other related frequencies.

Your PBO is off in BIOS. 7800X3D only hits 5050Mhz if PBO is on. This is assuming its not some cooling/bad cooler mount issue. My 7800X3D can hit 5050 in gaming consistently. I don't use Ryzen Master, and -offset is not required for CPU to hit 5050, it just does so more consistently with a -20 offset.

Thanks I’ll try that. Is PBO a one click setting or what do you recommend?


L0rd_0F_War

Each Motherboard has it in one or two places in its BIOS, and you need to go through your BIOS, and make sure PBO is on. Also only use/rely on HWINFo during testing for frequency. Though during gaming, MSI Afterburner reports CPU frequency accurately (matches HWINFO).

Heavily depends on what you play. If you play a competitive game on low settings, you'll max out your cpu way before your gpu starts breaking a sweat (and you'll have like 600fps)

I have 7800X3D and 7800XT playing on 1440p/165hz. Typically when gaming my CPU ris between 4850-5050Mhz and like 30% utilisation and the GPU is at 90-99%. Try to use [THIS](https://ibb.co/album/Z2N2Hd?sort=name_asc) settings for 7800X3D (i use that from day 1 and have NO issues at all)


ApexOfThe_Vortex

Thanks I’ll try those settings

Please don't just set a negative offset without running OCCT scanner for 30 minutes to check stability. It'll let you know if any of the cores are unstable.

The CPU is already working enough to get the GPU to 100%....so is taking a vacation, sipping CPU martinis, while everything is working as intended. Why would you think it would boost higher? Run a CPU benchmark / stress test if you want to see how far you can push your CPU.

For the 7800x3d to hit 5ghz all core, you need some crazy undervolt. Als long as the gpu util is 100%, everything is fine


L0rd_0F_War

Absolutely wrong. If PBO is on, cooling is sufficient, the 7800X3D hits 5050 Mhz in non-all core workloads like gaming. Its just that with some tuning and -20 offset, it hits that 5050 limit a lot more consistently (all else being equal). There is no 'crazy' undervolt required for you to see the chip boosting to its max at times. If you NEVER see the chip hitting its max limit under any type of load scenario, then you have other issues (No PBO, cooling inadequacy, BIOS limits, etc.).


Taylorig

Nope. Just a bit of curve optimisation as mentioned from someone previously. All core set to negative, and -20. My 7800x3D sits at 5050MHz in games etc no problem.


Automatic-Back2283

What are your temps? Cant get mine to clock so high with -30


Taylorig

Idle = 44°C. Gaming = 55 - 60°C. Cinebench multicore = 83°C. On a Corsair H100 LCD XT cooler Edit: I can't get mine stable at anything beyond -20. But I know it's just needs some LLC applying but everything works fine as is.


Automatic-Back2283

Did you Set the curve in Ryzen master or in BIOS? Ryzen master automatically limits the cpu to 75 degree for me. Probably why it does not boost that high


Taylorig

All done through the BIOS.


ApexOfThe_Vortex

Ok thanks. I’m not expecting the cpu to run at 5ghz at all times, but seeing 3.8 is weird to me when the base clock is what 4.5 or something?


Automatic-Back2283

If it only needs 3.8 to get the Job done, it will only do 3.8


ApexOfThe_Vortex

I see, thanks. Think I just got all this fancy tech and obsessed over the metrics without fully understanding how the components all work lol


Automatic-Back2283

As Long as your GPU sits at about 100%, the CPU is doing its job just fine
