While I'm in here, the latest 2.20 BIOS beta breaks Cool 'n' Quiet ... again. And yes wardog, I read your post about the azz whooping of the VRM. My VRM needs a good azz whooping. And as before, disabling C 'n' Q in BIOS allows normal overclocking. Looks like I won't bother turning that back on.

I stated 2.20, but I meant 2.22 beta is broken. You can overclock with either, but in 2.22 beta with Cool 'n' Quiet enabled, booting into windows will lock your clock to 1200MHz or around there regardless of the BIOS setting; actually as before task manager shows maximum CPU clock as what is set in BIOS, e.g. 3.8GHz, but actual running clock shown in the same panel maxes out in the lower 1100-1200MHz.

There might be a UEFI issue with that version, I don't have that board so I can't verify that either way.

What is your VCore mode set to, Auto? I have mine set to Offset, with the Offset value left on Auto. I have C n Q enabled, and C6 enabled. All cores at 38.25 to compensate for the BCLK droop. Using the AMD Ryzen Power Plan. The result:



Processor speed of 3.8GHz, which stays there due to the Ryzen Power Plan disabling core parking. If you check the VCore in the lower right side, you can see it ranges from 1.360V to 0.384V, so C n Q is active. We can also see the Core powers are varying quite a bit. Differences in CPU temperature also indicate it is working.
