I’ve been messing around with overclocking my 7900xt on linux to see if I can use the same settings as I do on windows. Unfortunately, it doesn’t seem nearly as stable on linux. For some reason adjusting the memory clock by about any amount causes a lot of screen flickering. Has anyone had much success overclocking their AMD gpu with the same settings as on windows? I’m running wayland, kernel 6.7.1 with a drm patch fo fix setting power level. Using LACT to do the overclock.
Fedora 39 + Mesa 23.3.2. Yea, the mclk is stable at 2500mhz default and even increasing it say 50mhz seems to cause flickering, that will sometimes go away then come back. Adrenaline version is latest, 23.12.1.
How far are you able to take mclk in Fedora without any voltage offset?
Does 1020 mV pass Vulkan memory test in Windows?
Basically no increase with default voltage either. If I bump mclk +10 it starts to flicker. Set it back to 1250 and no more flickering. I will have to test that on windows when I get some time.
huh, interesting. is the flickering like an intermittent white flash?
Also - sounds good.
