I don't disable the whole C6, that's too much and stresses the CPU. Setting it like above with power supply idle mode is already enough to prevent the freeze, and as I said, it only disables package C6, while leaving core C6 enabled.

Still not ideal, but will do until I'll get Ryzen 2.

Well, that explains the sequence, but not what it is. I suppose package refers to the whole set of cores in this case. Anyway, as I said, if it's all in the CPU, getting new one like Ryzen 2 can potentially provide one that works with PC6.

Is PC6 - package C6? That document doesn't give any details about what it is.

And you have what version of a firmware?


I'm using latest firmware 4.60. There is no explicit package C6 option. I only commented what I observe with zenstates.py after changing Power Supply Idle Control option. Apparently it affects package C6.

So what exactly is package C6? Does it refer to CPU package or something on the motherboard?

UPDATE: I found some info here, though it's talking about Intel: https://software.intel.com/en-us/articles/power-management-states-p-states-c-states-and-package-c-states#_Toc383778911

I suppose AMD uses similar terminology. So package C states still refers to the processor. If that's correct, there is a chance Ryzen 2 will fix this mess

That C-state 0x0 not supported by HW happens now always, so it's not related to my test above.

With Advanced > AMD CBS > Zen Common Options > Power Supply Idle Control set to "Common current idle" (instead of auto), I didn't get any freezes in a while, so I assume it's a valid workaround.

I noticed what changes after it's set in the firmware, using zenstates.py:

When set to auto (freezes happen):

C6 State - Package - Enabled
C6 State - Core - Enabled


when set to Common current idle (no freezes so far):

C6 State - Package - Disabled
C6 State - Core - Enabled


So apparently it disables package C6 state (while keeping core C6 state enabled)! Hopefully it can shed some light on what the problem is. I wonder if Ryzen 2 will be free of this issue.

What exactly is "package" in this context? Is it still part of CPU, or it's something on the motherboard?
