Just curious. My ASRock AB350M Pro4 micro-ATX AM4 mobo, has an option in the BIOS, something like "Core Disablement".
It offers various core config options to choose from, INCLUDING "4 + 0".
Which is really interesting, since I have a Ryzen 5 1600, which, supposedly, has cores disabled symmetrically across the CCXs. (3 + 3).
If the 4+0 setting WORKS, then that means that, one of the CCXs with the disabled core, can be re-enabled.
So if that works, then assuming that the BIOS can offer a 4+4 core disablement option, then you could (theoretically!) cause a 6C/12T Ryzen to enabled all cores in both CCXs, turning it into an 8C/16T part.
So... let me try this!
Edit: Hmm, doesn't seem to work. I tried 4+0, still ended up with 6C/12T in both Task Manager and CPU-Z. Then I tried 2+2, and got 4C/8T, then I tried 2+0, still 4C/8T.
So, it looks like the PSP is preventing the N+0 modes from working. Too bad.
