The kernel added support for realtime tuning of the frequencies a while ago, so I was pondering if the default setup may have led to excess overclocking. I left a console to watch the file /sys/kernel/debug/dri/0/amdgpu_pm_info which I understand contains the video card frequencies. The maximum "power level" I seem to reach is 4, at sclk 101500 and mclk 140000. I'm attaching the peak output of this file here. My video card is supposed to run at 1015 MHz (core clock) + 5600 MHz (memory clock). I don't fully understand how those numbers translate to frequencies, but from what I heard that represents the MHz * 100. If such is the case, my GPU clock is just right whereas my VRAM is actually under-clocked to a quarter of its default frequency! Can anyone confirm this so at least the hypothesis of bad clocks is out of the way? I may try testing with the kernel parameters "radeon.dpm=0 amdgpu.dpm=0" later: I tried doing so briefly but the performance is too horrible to play a game, so I'll instead leave a bot match running in spectator mode while I'm away.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
