I have a series on nightly jobs running on a Ryzen 9 3900X. These jobs have very low CPU demands, they ping several URLs at intervals of one minute and download a few kilobytes. I would like to set the computer to minimum consumption during this time. I got AMD Ryzen Master which allows to set the clock maximum speed as low as 650Mhz although the voltage is still set at 1.36875.
My question is, will lowering the voltage reduce power consumption even further? And if so, how much is it safe to lower the voltage for a clock speed under 1Ghz?
