Title: Rx vega m gl undervolt and overclock pp_od_clk_voltage values cannot be changed using echo Status in Linux: New Status in linux package in Ubuntu: New Bug description: GPU=Rx vega m gl Release=Focal, 20.04 (development) xserver-xorg-video-amdgpu version=19.1.0-1 (active development) /sys/class/drm/card1/device/pp_od_clk_voltage cannot be change beyond the parameters stated at the bottom of this file within the title OD_RANGE, as follows: OD_RANGE: SCLK: 225MHz 1011MHz MCLK: 300MHz 700MHz VDDC: 750mV 750mV The parameters in OD_RANGE are too constrictive and do not allow practicable overclocking/undervolting. Please could these values be changed to the following?: OD_RANGE: SCLK: 225MHz 1500MHz MCLK: 300MHz 850MHz VDDC: 300mV 1500mV This bug was also found here; https://gitlab.freedesktop.org/drm/amd/issues/574 The voltages and clock speeds cannot be amended above 1011Mhz, the HBM2 cannot exceed 700MHz and all voltages can only equal 750mV.
