AMD GPU overclocking - eviltoast

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.

    I just tested memtest_vulkan on linux, everything default but set Mclk to 1300, and it passed. But, there was still some flickering, not non-stop, but every once in a while I would get a flicker.

      Is this with a single display? Do you think you could capture a video of this flicker?

        I’ve got 3 displays. I just noticed something interesting; if I apply my settings in LACT I notice some flicker, if I then logout of my gnome session and relogin it seems fine, no flickering yet. I’ll do some more testing.
