I undervolted my AMD 6600xt and sometimes it would crash (maybe the undervolt was unstable) as I watched from a video.
In the video after he undervolted by increment, he increased the vram speed and changed the vram timing which I replicated. Today, my pc turned on but the monitor says no signal. I tried reseating, clearing the cmos and reseating the ram as well as reseating the GPU. I thought before that this was a ram issue so I bought a replacement pair of 2x8gb ram to my 1x16gb ram.
System specs:
AMD Ryzen 6600XT
Asus Prime B550M-K
Kingston Fury 3200mhz Cl16 2x8gb
Asus Dual OC 6600XT
650W Bronze PSU
