Zephyrus G16 (2024) GPU Powerlimit resets after reboot

What's wrong?

I have the Zephyrus G16 2024 model with a RTX 4080.
The default powerlimit was set to 90W for balanced mode and I maxed it out with G-Helper to 105W (+default 20W boost).
It worked great and the GPU boosted to around 115W in balanced instead of its usual 90W limit.
The Problem now is that after every windows reboot the setting doesn't apply anymore and the GPU is limited to 90W again.
The slider in G-Helper still sits at 105W, but i have to move it around and back to actually apply the setting again.

How to reproduce the bug?

1. Set profile to balance and adjust GPU powerlimit to max in G-Helper
2. Verify 115W GPU boost
3. Reboot system
4. GPU Boost is back to 90W with maxed powerlimit in G-Helper

Asus Zephyrus G16 GU605MZ

Additional information.

I tryed it with Armoury Crate installed and uninstalled.
Weirdly it seems that without Armoury Crate installed, it doesn't apply the new powerlimit at all but always stays at 90W max boost.
So at the time of my description I had it installed with every Asus Service killed except for the one that got started after Amoury Crate reinstallation.

@thephluxer hello,

On each start app would set all previously saved settings. Including your custom power limits (if you choose so)

08.05.2024 13:20:04: Mode = 0 : OK
08.05.2024 13:20:05: PowerLimit TGP (GPU VAR) = 25 : OK
08.05.2024 13:20:05: PowerLimit C0 (GPU BOOST) = 20 : OK
08.05.2024 13:20:05: PowerLimit C2 (GPU TEMP) = 87 : OK

I see that you have Armoury Crate installed along. Most probably it just overrides limits.

I would advice to uninstall AC, if you don't use it.

Thanks

@thephluxer P.S. If custom power limits did not work before by some reason, I would advice to click "Apply" under power limits section.

As some devices require all limits to be set in order to trigger "manual" mode where these settings work in a first place.

[thephluxer]

Thanks for the quick response.
I don't have "Apply" under the power limits section, just for the fancurve under the graphs.

I'll try to test it with AC uninstalled and create fresh logs from the attempt.

Cheers

@thephluxer I meant Apply under CPU part.

My point is that when you set "manual" in AC you can't selectively apply some settings, and not apply others.

So try to also Apply CPU power limits (pick something reasonable here). For example PL1/PL2 = 40W for gaming is usually good enough.

[thephluxer]

Ok i don't really understand what's going on.
According to GPU-Z the powerlimit without AC is effective and the GPU is using basically the same amount of power as with AC running and effective powerlimit.
But i just get consistently alot higher scores in Time Spy with AC running IF i apply G-Helper power limits afterwards. (~12250 vs. ~13500)

But it doesn't seem like an issue with G-Helper, AC just seems to apply some other magic settings i have to figure out.
So i'm closing the ticket, thank you very much for the help!

[seerge]

@thephluxer there is no magic.

• If you use AC default modes (i.e. not manual) it doesn't apply absolutely anything at all.
• If you use AC manual mode, you need to replicate it's settings in G-Helper as well - then you will get same result

My general advice is either use AC or G-Helper. If you use both in some strange combination, you only confuse yourself.

[seerge]

@thephluxer also on a side note.

If you use Turbo (or Manual) mode in AC. It by default applies some basic overclocking to GPU (i.e. core / memory offsets)

So you may want to set same in G-Helper (for example +200 core / +300 memory or so)

[thephluxer]

@seerge Ye i'm afraid i'm allready confused because I am just using the default profiles.

GPU mode standard and performance or windows as profiles (doesn't seem to matter).
So yeah, it shouldn't apply anything, but it apparently does because just having it installed or not changes my benchmark scores in a consistent and significant way without me configuring basically anything in AC.

I have to play around with it some more but yeah... i'm kinda lost. Seems pretty magical to me.

@thephluxer did you check my last comment about Core/Memory clocks ? :)

Check this topic and comments there https://www.reddit.com/r/ZephyrusG14/comments/1cmnbot/comment/l33bomz/

People seem get quite decent scores using same laptop as you do

[thephluxer]

@thephluxer did you check my last comment about Core/Memory clocks ? :)

Yeah i read that but i don't use turbo mode so it would not apply.
I'll have a look at the post and try to duplicate the settings and work from there.
Thanks for all your support!

[seerge]

@thephluxer but were you able to sort out your initial problem ? I.e setting custom GPU power limit using G-Helper alone ?

[thephluxer]

Yeah it looks like it.
Might have been the leftover service vom AC still running.
I'm experimenting with undervolting now to figure out if i can get back the performance.

[seerge]

@thephluxer you can check for leftovers from windows Services app.

As for GPU settings - I would still advice to set some Core/Memory clock offsets for GPU (it's literally undervolting). As you gain free performance for same power
