Description Rune Petersen 2018-07-06 18:15:47 UTC 
OverDrive volt and frequency table(pp_od_clk_voltage) is reset every time on power on.
For most desktop this is not a problem since, the GPU is not powered off until you turn off the computer.

When you use PRIME, the dGPU is powered off every time you stop using it, which again means that next time it is powered all OverDrive table changes will be lost.
