Manually Set CPU Scaling Frequencies

Post by visseroth »

I'm running the Ryzen 3950x (and loving it I might add) set to auto so the CPU scales as needed but I've noticed that when running Windoze the CPU will scale MUCH lower than when in Linux.
In Linux it'll scale down to about 1.8 to 2.1Ghz but in Windows cores will scale all the way down to something like 300 to 600Mhz, some cores will even go to sleep, or at least the Ryzen Master tool says they do.
Is there any way to manually set the CPU scaling governor to allow the cores to at least scale down in the 500Mhz range?
I figure until the kernels catch up that it's highly unlikely they'll go to sleep, if ever, or does anyone have any better suggestions (other than to run Windoze)?

After doing some research I don't think it's possible nor even if I did manually set the CPU scaling frequencies would the CPU report the appropriate frequencies as seen in this thread.....
