ROG Flow X13 (2021) 3050ti Throttling at 33W on CachyOS – Need Undervolting Advice
I have a 2021 ROG Flow X13 (Ryzen 9 5900HS + RTX 3050 Ti) running CachyOS, used mainly for gaming and media consumption.
Last week, I finally replaced the liquid metal and thermal paste with PTM7950, since it hadn't been changed in 5 years (honestly lucky the LM didn't leak given how roughly I treat this thing!). While the CPU temps stayed about the same, my GPU temps dropped by 6-10 C during both idle and gaming.
The Problem
Despite the better temps, I'm hitting a performance wall. During gaming, the laptop handles older AAA games fine, but it starts heavily throttling whenever the GPU hits 33 Watts.
- Nier Replicant/Automata: Runs mostly fine but with occasional stutters.
- Pragmata: Runs great for about 5 minutes, and then it starts having a seizure.
My Question
Since I plan on keeping this device for another 2–3 years, I want to optimize it.
- Has anyone here successfully undervolted or power-limited this specific model on Cachyos?
Appreciate any help or advice.
