Hey all,

Anyone ever deal with this issue?

I've confirmed that CCD parking is working properly in games and otherwise with bios defaults loaded + expo

When I turn on PBO, windows suddenly prioritizes the vcache ccd primarily over the higher frequency ccd. The only way I can get it to work somewhat normally is by disabling PSS support or turning off PBO. I don't want to do that bc as I understand it then windows doesn't know which cores are the preferred cores.

It's like flipping a switch.. if I enable PBO, threads all shoot over to CCD0 first and overflow to CCD1 which I feel is defeating the purpose of curve optimizer. With PBO off, it's the reverse (preferred way).
