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
