Asus ROG Flow Z13 GZ302EA 2025 - Undervolt option?

[sebdotffs]

Hello! I just switched from a Vivobook S16 with 370 HX to the Z13 and I noticed that for the 395+ there are no options for Undervolting as there were for the Vivobook.

Is this something that you're thinking of implementing in the future?

I know there are other tools there but I'd rather use G-helper as it's already almost the only app I use for tweaking and I suspect many of us feel the same.

Thanks!

@sebdotffs hello,

Can you check if undervolting via UXTU works? I.e. if it gives real gains / better scores, etc.

If so - I can try to migrate latest CPU details from UXTU, as G-Helper uses UXTU's library for undervolting anyway.

Hello @seerge ! Thanks for getting back to me! I just fiddled with the UXTU application a little and noticed that they also have a Per Core curve optimizer. I plan on undervolting the champion cores more later using this to see the gains, but do you think this mode could also be added to G-Helper?

I just did a quick test in Cinnebench multicore with stock vs using UXTU at -35 across all cores.
I used a simple 65W USB C charger with the Turbo mode. I think better numbers can be achieved with the stock charger.

Stock test:
The CPU clock was at a constant 3.7 GHz with sporadic jumps to 4.2 GHz for the entire 10minute duration - 1630 Points.

-35 MV Undervolt:
The CPU clock was at a constant 3.95-4GHz with sporadic jumps to 5 GHz for the entire 10minute duration - 1689 Points. - roughly 10% performance increase.

Stock:

-35 MV Undervolt:

I can do more tests if you need anything else specific later today, let me know.

Seconded.
I fiddled with UXTU some time last week, and it looks like two of my cores get unstable at around -25, but the other six can easily go down past -40. It would be nice to have that option in G-helper, even if its only implemented without GUI in json.

@sebdotffs @fricy latest release should allow you to undervolt both CPU and iGPU

alesx75 says "igpu CO not working, not on the Z13 as for the rest of the strix point family's"
Is this true? i seem some conflicting info around.
Im getting my Z13 tomorrow.

Who is that ? I don't have a Z13, but people who were asking to add iGPU undervolting mentioned that it seem to work for them :) You are free to try.

Last 2 posts seem to suggest something else:
#3871 (reply in thread)

But I will try this weekend if i get around it.
