I noticed yesterday that my 5950X never goes into C6 state, as Powertop only shows C0 C1 and C2. I know there have been issues with Zen and Zen+ regarding C6 states but it shouldn’t be a problem from Zen2 forwards? I tried running zenstates --c6-enable but that didn’t seem to work and I couldn’t find any settings in the bios of my Gigabyte X570 Ultra.

Is there a way to enable C6 states? I’m running Arch on the Zen kernel with ZFS modules. (I also notice the same behaviour on my Proxmox server which has a 5700X)

    Are you sure there’s no setting in your MoBo? It’s usually well hidden and perhaps under an unintuitive name.
