See: <a href="https://wiki.archlinux.org/index.php/AMDGPU#Overclocking">https://wiki.archlinux.org/index.php/AMDGPU#Overclocking</a> Yes, I use "c" to commit changes, the GPU frequency can always be modified, but the voltage does not take effect. I use parameters: # echo s 1 974 825 > /sys/class/drm/card0/device/pp_od_clk_voltage # echo s 2 1096 850 > /sys/class/drm/card0/device/pp_od_clk_voltage # echo s 3 1218 875 > /sys/class/drm/card0/device/pp_od_clk_voltage # echo s 4 1340 900 > /sys/class/drm/card0/device/pp_od_clk_voltage # echo s 5 1462 925 > /sys/class/drm/card0/device/pp_od_clk_voltage # echo s 6 1584 950 > /sys/class/drm/card0/device/pp_od_clk_voltage # echo s 7 1584 950 > /sys/class/drm/card0/device/pp_od_clk_voltage # echo c > /sys/class/drm/card0/device/pp_od_clk_voltage</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
