GPU Power limits for 2024 models

[seerge]

Hello,

Recently I have discovered that in 2024 models next to already existing GPU Dynamic Boost (ranging from 5W to 25W usually) new devices also have adjustable GPU power slider (!)

It's a "base" power, so your total GPU power limit will be GPU Power + Dynamic Boost (as it always have been)

Please keep in mind, that next to this setting, your GPU is also limited internally by it's own VBIOS (Video BIOS). And if your GPU has for exaple 125W VBIOS, it won't go above that no matter what :)

Best way to test limit is to download latest version of FURMARK and HWinfo. Run benchmark in a window and just monitor GPU power draw via HWinfo

If you are providing feedback, or believe something is not working as it should, please either post a new issue or include full app logs and clear scenario to reproduce as a comment here

Changes are live in latest releases

Is this not suitable for the 2023 model?

[seerge]

@famhu it's based on a new functionality asus has added in 2024 devices :) you can try this build - if you won't see a power slider - it means your device doesn't support it

[famhu]

I tried it, but I can't control the power consumption of the GPU on my computer. My model is G834JZ

[xSimone]

G834JZ is 2023 model not 2024 :x

[redlock81]

it does not work on my Strix G18 (2024) 14900hx 4080 it stays at 150w, AC keeps it boosted to 175w dynamic boost needs work, of course i thank you for your efforts!!!!!

[seerge]

Base power will be in range up to 150W, and with boost (+25W) it's total 175W. You can check that in Furmark.

This endpoints are SAME for all devices. Even without setting any GPU power limits, it will be maximized under Turbo mode.

P.S. This comment provides 0 helpful information. If you believe something is not working as it should, you need to provide a clear scenario to reproduce and upload logs as explained in issue template

[ModrnJosh]

Thank you Seerge, this is incredible!!! This essentially gives us functionality similar to the TGP slider in MSI Afterburner. Tested on the 4090 G16 and I can now achieve the full 125W even in Turbo or Balanced modes instead of being restricted to Manual mode for full TGP, wow!!

Also, this could be useful for vbios mods, which I will also test. This could mean potentially that I could load up a 175W vbios on the 2024 G16 and run it at maybe 150W instead to keep things cooler without having to limit clock speeds or anything. That would put the 2024 G16 at essentially the same power level as the 2023 Zephyrus M16, which is thicker and heavier.

[seerge]

@ModrnJosh great news. So everything is working as it should in this build ? In what range can you set GPU power and what happens if you go above (i assume you are locked with 125W) ?

Does it work for G14 ?

[ModrnJosh]

Hey, I know we’ve chatted about this a bit now but for anyone else reading, going above 125W doesn’t seem to boost the wattage any higher. It may or may not change the way the CPU acts towards dynamic boost, but I’ll be playing with it more. For now in the limited testing I’ve done, there doesn’t seem to be a difference between 105W + 20W dynamic boost and 125W + 25W dynamic boost as the machine maxes out at 125W regardless. And then I know you’ve tested it now a bit yourself on the G14, but I haven’t had much time to yet.

[xSimone]

Yay :3

[seerge]

Thanks for testing :)

[SylvesZhou]

4060 G14 2024 seem not have the GPU Power limits function.

[seerge]

It does:) as I have G14 2024. Do you use latest release?

[alex450]

maybe 4070 laptop got a wrong GPU POWER?（should be 115+25=140W）
tested at TX5pro (tuf gaming a16 chinese special version)
asus offically claims 140w for its 4070,and when using previous build and went furmark,it could reach more than 130watts
when v0.158, its locked at 110watts

[xSimone]

Yes. This is a very weird Laptop. :<

[seerge]

@alex450 great, does the build I linked work as intended?

[seerge]

@alex450 @ModrnJosh

I have changed logic of Max GPU Power setting a bit. So instead of just hardcoding it for each model, app would simply read it from nvidia-smi --query-gpu=power.max_limit --format csv,noheader,nounits command. (i.e. show "actual" power limit , based on what nvidia reports)

This should also accommodate situations when people use custom VBIOS (as @ModrnJosh does)

[alex450]

after solving this issue i would upload it

[seerge]

@alex450 what ?

GHelper.zip

this build works even better than former version!
when going furmark,it went straightly 140watts instead of floating between 120w and 140w

[seerge]

Great news, thanks for testing

[alex450]

stably running

[ModrnJosh]

Thank you!!!

[l0pl0p]

This is a great feature! I just grabbed a G14 today and am testing it--it isn't working for me. With GHelper installed and all ASUS services stopped/disabled/no armory crate, I am locked at 55W actual GPU no matter what I set it at in GHelper.

With armory crate turbo, I get ~90W.

Let me know if there's anything you'd like me to test!

[seerge]

@l0pl0p it's working absolutely fine, and tested very thoughtfully on G14. There is no "G-helper's" Turbo, all modes are baked in BIOS and are absolutely same.

You have apparently dragged power slider to 55w or did something wrong to your device.

If you want to apply custom limits, don't forget to check Apply. If you want to go back to all defaults how it was set by Asus - click Factory Defaults

[seerge]

@l0pl0p if you are interested, you may do same as another user in this comment #2141 (reply in thread) (reinstall latest nvidia driver), as this is likely driver issue rather g-helper's

[vansonffff]

when the G14(2024) resume from sleep，the GPU will be limited on 55W.
changing the batterymode（eco，balance，power) is not helpful，unless restart the laptop.

[seerge]

@vansonffff can you post a log as I was asking? Thanks

%APPDATA%\GHelper\log.txt

Also I see that GPU power slider shows 80w, while it can’t reach 65w on G14 2024. Do you use custom VBIOS or something like that?

[vansonffff]

NO，the bios is original.
I assume that could be a software conflict between ARMOURY CRATE）？

[seerge]

@vansonffff if you still have AC it can interfere of course

[vansonffff]

sorry，i can‘t get your point.
i use original ASUS AC adapter while using the G14(2024)

[vansonffff]

or it might a BUG on bios?
someone reflects same thing on G14(2023) about GPU55W

[vansonffff]

I‘ve uninstall ARMOURY CRATE，but GPU still limited on 55w

[seerge]

@vansonffff you have been explicitly asked to provide logs twice. Since you ignore this request all the time, it's impossible to assist you further. Thanks.

I have the same device as you claim to have (G14 2024) and can not reproduce behavior you indicate.

[vansonffff]

I'm sorry, I check the nvidia-msi ，I hope the new screenshoots may help，really appreciate .

[seerge]

@vansonffff G-Helper is not setting any limits on a driver level, and your screenshots show that nvidia-smi see a driver level limitation. It's some other software or Nvidia setting (like whisper mode or so that does it for you.

[vansonffff]

Thank you！
Follow your advice，I install the old versioin of Nvidia drive，and uninstall the NV EXP，it seems the problem has been solved.
and GPU power limits on the latest version of ghelper is working.

[seerge]

@vansonffff ok, thanks for confirming that it was Nvidia driver issue.
