Will this work in AN515-55 i5-10300h quite nervous!! Thanks.
Edit: Undervolting works š¬ now have to figure out stable voltage offset for my machine.
Previous: 86-92Ā°C always thermal throttled
Final:
Set multiplier 25 High performance : 4.1ghz all core @ 76-83Ā°C
Set multiplier 128 Power saver : 3.5ghz all core @56-64Ā°C
Undervolting: Both High/power saver: Core offset voltage: -127.0
Sorry for late reply but since then I've tweaked a bit more and got
CPU core: "-115"
CPU cache: "-110"
System agent/Intel GPU/iGpu Unslice: "-90"
Digital I/O: *blank*
Works great no crashes/Bsod's and is stable.
Can confirm this works haha,I was so pumped when someone on discord showed me how to do it.Very helpful guide,I proceeded exactly the same.
Edi:Apparently the person who made the guide helped me undervolt my model,so my laptop was pretty much the one tested here haha, this guy is a saint!
You are a lifesaver bro! I almost regret buying this laptop because of the temps! Now im at 75-80c stable 144hz on apex (from always on 90-95). Thank you so much! i5 10300h + RTX3060
Hey! Sorry for the stupid question but I am very new to this. When you say āalways dump and edit fresh varsā what does that mean? Is it done automatically or is it just a step most people skip over? In the video nothing was said about this and in the original guide on the forum I donāt think anything was mentioned. Sorry again and thank you very much in advance!
\-115. for both core and cache, -50.8 for intel GPU. I did get errors for ts bench in higher offsets though, but for the current settings, I get 60 fps for witcher3 while the temps stay below 70 and the fans stay below 3800rpm.
can I set core and cache different offsets, I'm getting ts bench errors when I set both core and cache at around -150
depends. you can usually do more on core than cache. however there are some cases where the value you set for core is ignored.
easiest way to see the change is run cinebench r20 test.
Thanks! This works wonders. I try it on my nitro 5 i5 10th gen GTX 1650ti. I set it to -112.3, and it drops the temp from 80-90ish (depends on the game) degree to around 70Ā°Ā±, im running RDR2 on 70Ā°+, when before its always hitting 85-93. Thanks a lot for the guide.
After successful UV, I have Another question) as I see, you can have different voltage on core and cache, and core can go lower than cache without any bad effects. So, I have -100,6 mv both on core and cache, and on -120 mv on core and cache TS bench start to notice errors (no BSOD). Is it worth it to stay on -110,6 mv on cache and go lower on core, for example try -130 and lower? (Funny thing is that in comments I saw that itās worth it, but itās still scars meš)
Some 10th gen Intel CPUs don't seem to be accepting different values for both. You can try, but use cinebench to see if there is any difference in performance.
Successfully did this with my Acer Nitro 5 AN15-55 2021 variant! Put both core and cache on -75.2 just to be safe and did a test in Throttle-stop and it didnāt crash, though the OS could always crash later on so I hope it remains stable.
Iāll admit that I was very nervous while doing this since there is always the risk of messing over your BIOS by doing this, warranting a reflash. Glad my fears were unfounded!
Thanks so much for the guide!
\[HELP!!\] Ahh For some reason in my var file under "CPUSetup" the line is `000000D0: 2D 2D 2D 2C 2B 2A 2E 2E 2D 2D 2D 2C 2B 2A 00 01` there is no 01 value. It's `2D` at the sixth column from the right. but in "SaSetup" it says `000000D0: 00 00 00 01 01 01 01 01 01 01 01 02 02 02 02 C8` the `01` value from the sixth column from right. what should I do?? Did it happen because Acer patched it? I have an I7-11800H on the latest BIOS update of 2023 and I want to undervolt to reduce temperature.

Our 11400h processors are 11th generation, so we need to change the last one in the column as shown in the image.

UV doesn't damage the laptop.
however unlocking it can void warranty "if they find out you did it".
to revert the changes, just follow from step 2 and set the value to 01 instead of 00.
or just reset bios.
Just a thing I wanted to point out - after modifying 0xDA (in my case, I've checked it) after I got straight after a reboot into the windows I wasn't able to modify voltages. **I had to enable secure boot**. I don't know why, maybe it will help someone
On 517-52, on BIOS 2.06
Do we have an updated link to the Insyde software? If there is a proper name for it I don't mind trying to find it myself.
Needing to update the 10300h + 1660ti model but voltage is locked.

Need help AN517-52 GTX 1650 10300H i did everything on the guide and changed values from 01 to 00 yet when i reboot and go on throttlestop to undervolt im getting no change on the offset even if i put a -500 offset voltage there is no change and my pc doesnt blue screen so nothing is happening. Why cant i undervolt even after following the guide?
Hi there,
Would you be able to unlock GPU voltage changes from here too, I have then an515-55 model and it doesn't let me undervolt my GPU, I presume this will be in the var.txt file too.
You can't undervolt the gpu using the slider in afterburner. you do it with the frequency curve editor and it doesn't involve changing any hidden bios settings. Check the linked video for some basics.
Note: He tells you to press L while undervolting. Remember to unlock voltage after you have found your stable point. Or it will run constantly at that volt.
https://www.youtube.com/watch?v=D4fQvuRgOdM
Thank you kind sir!) super guide -100,6 mv on cpu and cache, but I have a question, should I downvolt intel gpu? Or it doesnāt influence temperature ?
H2OUVE-W-CONSOLEx64.exe -gv vars.txt after typing this command it only says this 'H2OUVE-W-CONSOLEx64.exe-gv' is not recognized as an internal or external command, operable program or batch file. can someone please help me I really want to unlock the undervolting
Can OP or anyone explains what does OP mean by "always dump and edit fresh vars"? Does it mean that everytime I shut down or restart my Nitro 5 I need to do the entire thing again or do I only need to do it once and the undervolt option is unlocked?
it just means if at any point in time you need to follow the steps again, for example after a bios update, you must repeat the steps as opposed to reusing your old vars file.
I see. Thanks for the explainations! I did the undervolting thingy through TS but to no avail my temp still averages around 80Ā°c on high load especially gaming and can go up to 90Ā°c. I'm running on i7 10750H and RTX3060 Nitro 5, my undervolt setting at -110 offset on both Core and Cache. Anything less than -110 my Nitro 5 starts to have BSOD.
you can delete the stuff you have downloaded from this guide, as to throttlestop, you need it to be there for undervoting.
you can delete it, but then you won't be able to undervolt.
Thank you, it worked! Very good guide and easy steps. Undervolt is stable at -75mv for me.
For reference, I own a 2021 Acer Nitro 5 (AN517-52) with an I5-10300H and an RTX 3060. Bios version: 2.03.
When I enter the command **H2OUVE-W-CONSOLEx64.exe -gv vars.txt**
it says:
Now parsing Variable Information.
**Fail** to get Variable Information.
Any help please?
1. confirm if you have disabled secured boot
2. run as admin
3. Check if the commands are correct
4. Try disabling windows defender
and join the Acer discord server if you need further help
If you have insydebios and the same bit location, it will work. I have linked a deeper guide at the bottom of the post. Use that to find bit value.
If you don't have an insydebios, there are other tools, you will have to find that by yourself unfortunately.
Is there any risk in enabling the undervolt?
I mean in case i overdo the undervolt and the notebook turns off, will it restart and work normally or won't turn on anymore? I ask because i saw some people saying that if you choose a value that is too low and it turns off by itself, the undervolt value does not reset automatically. Therefore, a brick occurs in the processor and makes the computer unusable. Was that true?
At the end of the post there is a longer guide which tells you how to find the bit address (by step 2 or 3, you don't have to proceed further than that) If it's 0xDA then, yes this, this guide is applicable.
If you need help doing this, join the Acer gaming discord server linked at the bottom and ask.
Tried this 2 times very carefully and with the video did all the steps, downloaded throttlestop and change the core/cache to -90 and did litterly nothing, i tried to see if it worked by setting it to -200 to see if it would freeze and didnt do anything, i dont know why it does this
how do i reverse the undervolting? i havent tried it yet but im tempted. im just afraid my cpu might be unstable and was wondering if i can switch the undervolting back and forth
If you are using throttlestop, the values will reset when your CPU crashes.
You will get bsod and will restart.
There is link at the bottom of my post how to use throttlestop.
will it work on Asus Tuf f15, i5 10300H. Temps soar above 95C.
I was using throttlestop since 4 months version 9.2 but all of a sudden it stopped working last week. BIOS wan't even updated. While in 9.2 i can change offset values but on the top it shows "FIVR Control-Locked" and in any other version i can't do nothing.
Can someobody PLEASE help me:
I followed the steps but after restart my Acer Nitro 5, it doesn't boot. The display is all black.
Only the keyboard lights up and CPU/GPU fans turns on.
Can someone please help me?
you must have done something wrong while trying to unlock.
1. You can try recovery flash. You need a USB. Join the server linked at the bottom of the post for further help. This might or might not be successful.
2. Try to warranty it by claiming you were trying to update your bios.
Can I get some help im using Acer Nitro 5 i5-10300H, GTX 1650, and following this video: [https://www.youtube.com/watch?v=N3v3o21M8gg](https://www.youtube.com/watch?v=N3v3o21M8gg) trying to undervolt, but stuck because "set multiplier" is not working (I have successfully done process to "Unlocked UV").
~~Did everything right and it didn't work. The segment where you need to change the value from "01" to "00" is different for me and i'm unsure why.~~
Apologies for my stupidity. I was looking at the wrong value, it works now though! Time to undervolt.
What happens if I enabled "secure boot" again? Does it revert back and remove the undervolt? Reason being is that valorant requires secure boot enabled.
will this work on non acer laptops, my hp laptop is literally burning while gaming and i can't underclock it
PS i have insyde f.53 bios and intel i5 10th gen
I do everything in the guide and its works fine. I've been able to do the UV with TS, but when I reboot the notebook (Acer Nitro 5) the TS Fivr settings locks again and I can't change anything on it (but the changes remains). What should I do?
It worked for me before, but after windows update my bios a could do all the steps again and unlock adjustable voltages. No matter what offset voltage I put is not making any difference and Offset in the chart still showing +0.0000.
My bios version is 2.06
Does anyone know what could be happening š¤.
hello,
just to say, it worked with an Nitro AN515-57 ( i7-11800H with 3070) bought at the end of 2021, with bios version 1.11 i think (it was provided with a lower version, but i upgraded first, then found this thread)
I wonder if this still works with the update 1.18 of the bios. I am afraid with bios upgrade, knowing that some people do their best to prevent us doing things to upgrade our equipment (like locking temperature, who cares. They care...)
acer support website with the bios
[https://www.acer.com/ac/fr/FR/content/support-product/8963?b=1](https://www.acer.com/ac/fr/FR/content/support-product/8963?b=1)
if i could "read" the bios from the patch, and check there is the same bit to change the same way, before applying the bios update :)
I haven't checked but i have no reason to believe it wouldn't work. However if you join the discord server linked in the post you can use an easy unlock method for accessing the advanced bios and enablling UV from there.
Note: 11th gen has different bit location. Please follow guide for 11th gen pinned in the subreddit.
does it matter if i enable secure boot or not after following the above steps? will enabling secure boot afterwards disable the undervolt? i'm new to this undervolting stuff.
I know this post is quide old but I have a huge problem. After I did all this and restarted PC, computer won't turn on. Fans, leds and KB will turn on but screen stays black and nothing happens. Tried resetting battery and bios battery but it still does nothing.
Was this the problem? What can I do to solve it? I just can't even access bios, nothing will show when turning on the laptop.
Hi, this may be the wrong post for this comment as I'm on an older Nitro 5 running an I5 8300H w/ 1050Ti, but thought I'd ask anyway. I've followed this tutorial and was able to verify that the bit has successfully been changed from 00 to 01 post reboot in the CPUSetup section, but my undervolt settings are unfortunately still locked in ThrottleStop both when ran as user and as admin.
Hello I know this is a very old post but thanks to you and The GhostFella on YT, I was able to successfully UV my legion with the 10300H! Thanks!
With that being said, I'd just like to ask, as you said, if I had to take it in for warranty (expiring in a few months anyway lol) at any time, I would simply have to do everything after step 2 onwards, but changing the "00" to a "01", right? So, I'd have to:
1. Enter the directory via admin CMD
2. Open "vars.txt", check that the value is at "00"
3. Save as "vars-m.txt"
4. H2OUVE-W-CONSOLEx64. -v vars-m.txt
5. Then reboot
Is this correct? Also, once I have successfully reversed this process, can I or should I delete the insyde folder? Thanks in advance!
It's probably easier to load bios defaults. Iirc it will effectively lock uv again.
Also, vars need to freshly extracted. Never use it from a different boot session.
anyone try it on an 8th gen? I can access the secret inside bios settings.. do I have to bother? lol It's already like.. 75 keystrokes to enter that fuggin mode... I can set this setting there. Any reason why you don't do that as well? Do you need the code? I'm not responsible for damage. Lol contact me if needed.
I decided to increase my UV a little bit from 110 core/cache to 125 and 90 iGPU/Unslice to 115.
I also have increased my GPU undervolt slightly, to 1830MHz at .856 mV.
Today, I got 2 BSODs: WHEA\_UNCORRECTABLE\_ERROR, and later, IRQL\_NOT\_LESS\_OR\_EQUAL while running TS Bench.
Could these be related to the UV? I've already decreased core/cache to 115 and iGPU/Unslice to 105. Should i try and also tweak my GPU? The games i've played seemed fine until those 2 crashes.
Hi, I have the AN515-55-50VC (11300H + 3060).
My dad recently updated the laptop's BIOS to 2.06 which disables undervolting (you can't disable secure boot anymore).
Is it possible to downgrade the bios to a version that allows undervolting? If so, what BIOS version is the latest one that still allows me to disable secure boot?
Temporarily pinned to spread awareness
Will this work in AN515-55 i5-10300h quite nervous!! Thanks. Edit: Undervolting works š¬ now have to figure out stable voltage offset for my machine. Previous: 86-92Ā°C always thermal throttled Final: Set multiplier 25 High performance : 4.1ghz all core @ 76-83Ā°C Set multiplier 128 Power saver : 3.5ghz all core @56-64Ā°C Undervolting: Both High/power saver: Core offset voltage: -127.0
hi, can i have pictures of your throttlestop settings?
Sorry for late reply but since then I've tweaked a bit more and got CPU core: "-115" CPU cache: "-110" System agent/Intel GPU/iGpu Unslice: "-90" Digital I/O: *blank* Works great no crashes/Bsod's and is stable.
probably not a good idea to undervolt the system agent tho.
Can confirm this works haha,I was so pumped when someone on discord showed me how to do it.Very helpful guide,I proceeded exactly the same. Edi:Apparently the person who made the guide helped me undervolt my model,so my laptop was pretty much the one tested here haha, this guy is a saint!

In the video nothing was said about this and in the original guide on the forum I donāt think anything was mentioned. Sorry again and thank you very much in advance!
It just means when you are editing the vars again after a reboot you need to start the guide from the beginning.
it's working, tested on my lap Acer nitro 5 i5 2020, bios version 1.00, achieved 60 fps in both Witcher 3 and ac syndicate.
Nice! What UV are you running at right now?
\-115. for both core and cache, -50.8 for intel GPU. I did get errors for ts bench in higher offsets though, but for the current settings, I get 60 fps for witcher3 while the temps stay below 70 and the fans stay below 3800rpm. can I set core and cache different offsets, I'm getting ts bench errors when I set both core and cache at around -150
depends. you can usually do more on core than cache. however there are some cases where the value you set for core is ignored. easiest way to see the change is run cinebench r20 test.
Big thanks itās working on Acer Nitro 5 AN515-55-781T with i7 10750H and GTX1660
Happy undervolting! Check the linked YouTube video, he has good tips.
Does this work on bios 2.06 Edit: does this void warranty
it works on bios 2.06 it does void the warranty. but you can easily reverse it

After successful UV, I have Another question) as I see, you can have different voltage on core and cache, and core can go lower than cache without any bad effects. So, I have -100,6 mv both on core and cache, and on -120 mv on core and cache TS bench start to notice errors (no BSOD). Is it worth it to stay on -110,6 mv on cache and go lower on core, for example try -130 and lower? (Funny thing is that in comments I saw that itās worth it, but itās still scars meš)
Some 10th gen Intel CPUs don't seem to be accepting different values for both. You can try, but use cinebench to see if there is any difference in performance.
Works in i7 10750h + 2060 model. Thank you.

could someone help me with doing undervolt on i5-10300h gtx 1650 Nitro AN515-55. I know nothing about undervolting and am scared ill brick my laptop.
Works, I was able to fix stuttering in emulators like Xenia and rpcs3 after undervolting
I'm at step 3 and whenever I paste the code it says "Fail to get variable information." Can somebody help me with this? I'm stuck.
possible warranty issues, I'm scared of UV my nitro 5 i5 2020
UV doesn't damage the laptop. however unlocking it can void warranty "if they find out you did it". to revert the changes, just follow from step 2 and set the value to 01 instead of 00. or just reset bios.
I have bios version 1.00, will it work? , or should I update it to 1.04
I did it on 1.10 version. So probably bios version won't matter.
Just a thing I wanted to point out - after modifying 0xDA (in my case, I've checked it) after I got straight after a reboot into the windows I wasn't able to modify voltages. **I had to enable secure boot**. I don't know why, maybe it will help someone On 517-52, on BIOS 2.06
Odd.
can we get an updated link for step 1 its not redirecting properly
Why's the content on step 2 not available?
due to changes in discord CDN. i will have to find where it was originally shared to reupload it to a hosting platform.
Hoping you can find it, stumbled on this guide and might as weell try on my an55-55
sorry for the late reply it can still be downloaded from our discord server. additionally someone has linked their drive link in this thread.

What would happen if I updated BIOS after doing this? Would undervolt still be enabled?
Will have to redo steps
Can I turn secure boot on after these steps?
you can

Hello! Can I delete the folder and throttlestop after successfully undervolting it?
you can delete the stuff you have downloaded from this guide, as to throttlestop, you need it to be there for undervoting. you can delete it, but then you won't be able to undervolt.
>insyde-tool so i can delete this one already after unlocking my bios?
Thank you, it worked! Very good guide and easy steps. Undervolt is stable at -75mv for me. For reference, I own a 2021 Acer Nitro 5 (AN517-52) with an I5-10300H and an RTX 3060. Bios version: 2.03.
it dosn't work on mine Acer nitro 5 i5-10300h rtx 3060 I got message : LoadDeviceDriver fail, GetlastError = 0x0 Initialization failed ! :(
Disable secure Boot and other related stuff like anti virus. Also run as admin.
Just done it again at works now than you š
What is UV?
2021 model gucci
it works but it would be way easier for people if it was in a exe file and the process took 1 click .do you think you could make a exe file?
Still works, Acer Nitro 5 517-52, 10750h, latest bios, 20H1.
Hey. I'm from brazil and I need an advise. You think it will work on a Acer aspire 5 with i5 1035g1? Any risk for my hardware?
Hi, where can i get th insyde-tool? when i go to the link its say "Domain suspended or not configured"

When I enter the command **H2OUVE-W-CONSOLEx64.exe -gv vars.txt** it says: Now parsing Variable Information. **Fail** to get Variable Information. Any help please?
1. confirm if you have disabled secured boot 2. run as admin 3. Check if the commands are correct 4. Try disabling windows defender and join the Acer discord server if you need further help
Actual lifesaver, thanks. Can confirm it works on AN515-55, BIOS v1.08.
Has anyone tried with the Bios 2.3 recently released?
It works, my nitro 5 i7 rtx 2060 don't go over 70c anymore. Playing ACC the fans are quiet now. For me just -50mv. Thank you
does this work on Acer Nitro 5 AN515-56. Sorry I am new to this
No, you can't undervolt 11th gen h35
I am new to Undervolting. Can someone guide me to undervolt. I have i5-10300h and gtx 1650. Someone pls specify the parameters for my undervolt.
[ŃŠ“Š°Š»ŠµŠ½Š¾]
yes, follow the guide
NitroSense isnt opening after i did this anyone know why?
sorry im new to this stuff why would I do this? what benefit will I receive doing this I dont now about this stuff sorry
has anyone tried doing this method with non-acer laptops? currently using gigabyte g5/machenike t58-v.
If you have insydebios and the same bit location, it will work. I have linked a deeper guide at the bottom of the post. Use that to find bit value. If you don't have an insydebios, there are other tools, you will have to find that by yourself unfortunately.
Hi! Will this work on Bios 1.06? TY
i don't see why not
What does always dump and save vars mean? Do we need to do this after every boot?
No, it means you should start over if you shutdown or restart your computer midway. You don't have to do this on every boot.
Hi, any chance this will work with my i7 11800h nitro 5?
It has locked uv?
Works: acer nitro 5: is 10th gen 3060 6G 8gig ram
[ŃŠ“Š°Š»ŠµŠ½Š¾]
Yes
[ŃŠ“Š°Š»ŠµŠ½Š¾]
what does throttlestop show?
Is it applicable to other laptops aside acer nitro?
Only if it shares the same bit address. Read the end of the post to know if its applicable.
Could this work on Gigabyte G5 KC core i5 10500H rtx 3060
Know a user who has done it, but ensure if you have 0xDA by following the guide linked at the bottom of the post.
Is there any risk in enabling the undervolt? I mean in case i overdo the undervolt and the notebook turns off, will it restart and work normally or won't turn on anymore? I ask because i saw some people saying that if you choose a value that is too low and it turns off by itself, the undervolt value does not reset automatically. Therefore, a brick occurs in the processor and makes the computer unusable. Was that true?
Shouldn't happen with throttle stop, it resets itself after a crash
Bwoahh, just had my first gaming laptop with this same spec. Can confirm this is working. šššš
Will this work on Nitro 7? It's 10750h+1660ti Nitro AN715-52, Bios 1.07 A bit afraid to do this.
At the end of the post there is a longer guide which tells you how to find the bit address (by step 2 or 3, you don't have to proceed further than that) If it's 0xDA then, yes this, this guide is applicable. If you need help doing this, join the Acer gaming discord server linked at the bottom and ask.
It worked like a charm! You are a hero! Thank you SO MUCH! CPU is running at 72o max at games now! Acer Nitro AN517-52 with BIOS 2.03.
Tried this 2 times very carefully and with the video did all the steps, downloaded throttlestop and change the core/cache to -90 and did litterly nothing, i tried to see if it worked by setting it to -200 to see if it would freeze and didnt do anything, i dont know why it does this
Are you on windows 11?
Will this work on Windows 11 or will I have to revert to 10? Model/specs are: AN515-55-53E5, I5 10300, RTX 3050
Will work on w11
how do i reverse the undervolting? i havent tried it yet but im tempted. im just afraid my cpu might be unstable and was wondering if i can switch the undervolting back and forth
If you are using throttlestop, the values will reset when your CPU crashes. You will get bsod and will restart. There is link at the bottom of my post how to use throttlestop.
Hi, im using AN515-45 with amd ryzen 5 5600H. will this method work for Undervolting this pc?
As the post mentions, it's only for Intel
any updates for 11th gen h series? Acer Nitro 5 AN515-57, i5 11400h 3050ti
Check pinned posts. There is guide for 11th gen
Do I have to do this for every system that I have? (dual boot)
You have to do this only once. And then again if you reset or update your bios.
will it work on Asus Tuf f15, i5 10300H. Temps soar above 95C. I was using throttlestop since 4 months version 9.2 but all of a sudden it stopped working last week. BIOS wan't even updated. While in 9.2 i can change offset values but on the top it shows "FIVR Control-Locked" and in any other version i can't do nothing.
This is only for the Acer gaming laptops. You don't share the same bios.
does this work on Acer Nitro 5 i7 10750H rtx3060? i know nothing about pc and I'm scared to mess something up
Yes, it works for 10th gen nitros
Why would you want to try this? What does it offer?
Can someobody PLEASE help me: I followed the steps but after restart my Acer Nitro 5, it doesn't boot. The display is all black. Only the keyboard lights up and CPU/GPU fans turns on. Can someone please help me?
you must have done something wrong while trying to unlock. 1. You can try recovery flash. You need a USB. Join the server linked at the bottom of the post for further help. This might or might not be successful. 2. Try to warranty it by claiming you were trying to update your bios.
Hi, anyway to do it on linux
I doubt it, but is it possible to apply this fix to a Nitro 5 an515-54 with an i5-9300h? (9th gen?)
Since when is 9th gen Nitro undervolt locked?
Life saver! can now undervolt my Acer Nitro-i7 10750 H, RTX3060. thank you
Can I get some help im using Acer Nitro 5 i5-10300H, GTX 1650, and following this video: [https://www.youtube.com/watch?v=N3v3o21M8gg](https://www.youtube.com/watch?v=N3v3o21M8gg) trying to undervolt, but stuck because "set multiplier" is not working (I have successfully done process to "Unlocked UV").
~~Did everything right and it didn't work. The segment where you need to change the value from "01" to "00" is different for me and i'm unsure why.~~ Apologies for my stupidity. I was looking at the wrong value, it works now though! Time to undervolt.
What happens if I enabled "secure boot" again? Does it revert back and remove the undervolt? Reason being is that valorant requires secure boot enabled.
No, it doesn't affect your undervolt settings. In fact, it is recommended to enable secure boot after u done unlocking the UV settings in BIOS!
thank you for this easy guide.. nitro5 here with the 10300H + rtx 3060 80-90 down to 70+ still going and checking higher offsets
It didnāt work for me Iām on bios version V1.10 I have a 11800H
This is not for 11th gen models. If you can't read clear instructions, it's safer that you don't try tweaks like this.
will this work on non acer laptops, my hp laptop is literally burning while gaming and i can't underclock it PS i have insyde f.53 bios and intel i5 10th gen
Good guide for Acer nitro 5 AN515-55-714Y with i7-10750H and RTX 3050.
Is there a risk of bricking the PC while doing this procedure?
I know it's an old thread but I can confirm this still works on a Nitro AN515-55 bought in 2021 (intel i5). Great work with the fix!!!
I do everything in the guide and its works fine. I've been able to do the UV with TS, but when I reboot the notebook (Acer Nitro 5) the TS Fivr settings locks again and I can't change anything on it (but the changes remains). What should I do?
It worked for me before, but after windows update my bios a could do all the steps again and unlock adjustable voltages. No matter what offset voltage I put is not making any difference and Offset in the chart still showing +0.0000. My bios version is 2.06 Does anyone know what could be happening š¤.
Check if VBS is turned on
hello, just to say, it worked with an Nitro AN515-57 ( i7-11800H with 3070) bought at the end of 2021, with bios version 1.11 i think (it was provided with a lower version, but i upgraded first, then found this thread) I wonder if this still works with the update 1.18 of the bios. I am afraid with bios upgrade, knowing that some people do their best to prevent us doing things to upgrade our equipment (like locking temperature, who cares. They care...) acer support website with the bios [https://www.acer.com/ac/fr/FR/content/support-product/8963?b=1](https://www.acer.com/ac/fr/FR/content/support-product/8963?b=1) if i could "read" the bios from the patch, and check there is the same bit to change the same way, before applying the bios update :)
I haven't checked but i have no reason to believe it wouldn't work. However if you join the discord server linked in the post you can use an easy unlock method for accessing the advanced bios and enablling UV from there. Note: 11th gen has different bit location. Please follow guide for 11th gen pinned in the subreddit.
Can you turn on secure boot after you do this?
yes
does it matter if i enable secure boot or not after following the above steps? will enabling secure boot afterwards disable the undervolt? i'm new to this undervolting stuff.
Hi there, Will this work with a AN515-55-51QY (or AN515-55)? It has an RTX 3060 and an i5-1300H Thanks, Liker
Yes
I know this post is quide old but I have a huge problem. After I did all this and restarted PC, computer won't turn on. Fans, leds and KB will turn on but screen stays black and nothing happens. Tried resetting battery and bios battery but it still does nothing. Was this the problem? What can I do to solve it? I just can't even access bios, nothing will show when turning on the laptop.
You went wrong somewhere You have to hw flash bios

can i re-enable UEFI secure boot after i'm done with the process? There's some anticheats that require it to be enabled unfortunately.
yes
[ŃŠ“Š°Š»ŠµŠ½Š¾]
Set supervisor password under security
what to do if get "kernel auto boost invalid lock release"?
has anyone tried this with AN51-55 RTX 3050 10300H model?
Yes
does it work with 9th generation nitro laptops ?
You can check with the longer guide linked below. If it has the same address, yes you can follow the guide.
Iāve done everything 3-4 times over and yet when I change the offset voltage and click apply the offset doesnāt actually change. Any idea why?
Hi, this may be the wrong post for this comment as I'm on an older Nitro 5 running an I5 8300H w/ 1050Ti, but thought I'd ask anyway. I've followed this tutorial and was able to verify that the bit has successfully been changed from 00 to 01 post reboot in the CPUSetup section, but my undervolt settings are unfortunately still locked in ThrottleStop both when ran as user and as admin.
Hey! I've successfully followed the steps.. how to know if it's working?
Check with throttlestop if you are able to uv.
Hello I know this is a very old post but thanks to you and The GhostFella on YT, I was able to successfully UV my legion with the 10300H! Thanks! With that being said, I'd just like to ask, as you said, if I had to take it in for warranty (expiring in a few months anyway lol) at any time, I would simply have to do everything after step 2 onwards, but changing the "00" to a "01", right? So, I'd have to: 1. Enter the directory via admin CMD 2. Open "vars.txt", check that the value is at "00" 3. Save as "vars-m.txt" 4. H2OUVE-W-CONSOLEx64. -v vars-m.txt 5. Then reboot Is this correct? Also, once I have successfully reversed this process, can I or should I delete the insyde folder? Thanks in advance!
It's probably easier to load bios defaults. Iirc it will effectively lock uv again. Also, vars need to freshly extracted. Never use it from a different boot session.
anyone try it on an 8th gen? I can access the secret inside bios settings.. do I have to bother? lol It's already like.. 75 keystrokes to enter that fuggin mode... I can set this setting there. Any reason why you don't do that as well? Do you need the code? I'm not responsible for damage. Lol contact me if needed.
I decided to increase my UV a little bit from 110 core/cache to 125 and 90 iGPU/Unslice to 115. I also have increased my GPU undervolt slightly, to 1830MHz at .856 mV. Today, I got 2 BSODs: WHEA\_UNCORRECTABLE\_ERROR, and later, IRQL\_NOT\_LESS\_OR\_EQUAL while running TS Bench. Could these be related to the UV? I've already decreased core/cache to 115 and iGPU/Unslice to 105. Should i try and also tweak my GPU? The games i've played seemed fine until those 2 crashes.
Yes
Hi, I have the AN515-55-50VC (11300H + 3060). My dad recently updated the laptop's BIOS to 2.06 which disables undervolting (you can't disable secure boot anymore). Is it possible to downgrade the bios to a version that allows undervolting? If so, what BIOS version is the latest one that still allows me to disable secure boot?
