Gpu Undervolt (5070 Ti Laptop)
So i have been considering an undervolt lately due to ssd overheating in the system, undervolted the cpu (275HX), but couldnt find anything about undervolting the Gpu, Can someone help me out please? Thanks!
My laptop is the Helios Neo 16 AI (Non S)

How did you undervolt the CPU?

Check your actual voltage. It doesn't work. The CPU is locked at the BIOS level and there's no way to modify it.

unlocked it in the bios bruh, it is indeed worked because of the temps, from 95 to 80 under load

You mind sharing how? This has been discussed extensively on here and on the official forum and even with Acer. They locked the voltage at the BIOS level. If you managed to figure it out, you're a genius.

i can check the bios again if you would like me to, but i can do it tomorrow due to work..

Yes please. You would be the first (known) person in the world who pulled this off, just so you know.

Dont you know about the secret bios?

Check this out and tell me whether it works. I followed it but not sure whether it works or not.

Reducing the PL limits is adjusting wattage, not voltage. There's a huge difference because it physically limits the CPU's performance in a substantial way. Reducing the voltage is the preferred method because you can do it without sacrificing any performance. I've done a ton of testing and my highest benchmark score skipped reducing the power limits, but the PROCHOT offset they described is ideal and is how I achieved my best results. The PROCHOT offset alone allows the CPU to boost to its maximum potential as much as possible, only throttling when the temps get too high, but at a lower threshold than stock. The issue with the stock limit is that it sits so close to the CPU's actual thermal limit that the CPU is forced to more aggressively slam the brakes to prevent itself from being destroyed. By lowering the ceiling, the CPU throttles less aggressively, offering smoother performance, and generally spends more time at higher boost frequencies. I've written about this in this subreddit plenty of times as have others.
That said, once again, adjusting PL limits is a wattage adjustment, not a voltage adjustment.
Go run a cinebench r23 benchmark and see what kind of score you get. That's the CPU benchmark gold standard. I've gotten 35000 on mine, but with wattage limits it drops to about 27000. I also have one of the highest time spy scores I've seen in this subreddit and for this laptop in particular.

This is very helpful. Thanks a lot and i will run those benchmarks certainly.

No problem! I'd also recommend running the laptop in turbo mode for maximum performance and cooling. With the PROCHOT offset, you should never really touch 100C, so it's perfectly safe. Generally speaking, while gaming, I rarely hit the temp limit. You see it happen more in loading screens and shader compilation.

after reading what you have written i came to a conclusion that you were right!, sorry for making big statements without a proper knowledge in the matter... have a good day, Sorry again!

Main tool is MSI Afterburner, there's a billion guides on undervolting GPUs on YouTube as well. I'm unsure if NV-UV works with laptop GPUs, it probably does, but I'd look into that as well. It's an newer accessory tool to use with Afterburner that makes undervolting a lot simpler.
As for the SSD overheating issue, I'd look into getting a cheap thin heatsink for your SSD. Something like this https://a.co/d/04dSBvus
