Comment # 16
on bug 108493
from Timur Kristóf
Hi, After some more experimentation it seems that increasing the highest mclk voltage above 900 mV and setting all other voltages in pp_od_clk_voltage in such a way that they remain below 1000 mV, is a viable workaround that makes the GPU stable. Here is what I do to achieve this: echo "2" > /sys/class/drm/card0/device/pp_sclk_od echo "2" > /sys/class/drm/card0/device/pp_mclk_od echo "s 0 300 750" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "s 1 588 765" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "s 2 952 900" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "s 3 1041 970" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "s 4 1106 970" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "s 5 1168 970" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "s 6 1209 970" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "s 7 1244 970" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "c" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "m 0 300 750" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "m 1 1000 850" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "m 2 1750 970" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "c" > /sys/class/drm/card0/device/pp_od_clk_voltage After running this script, I can play on the GPU for several hours and I don't see the hang happening anymore.
