Chinese BTC-X79-H61 motherboard - only 2 cores

[ivanpop]

Hello,
I have one of these boards, that were used back in the days of the 3060 non-LHR cards.

The problem with these boards is that they only detect 2 cores of whatever CPU is installed on them. I guess it's to prevent overheating and because there was actually no need for more back then.
Now, I want to mine Dynex, but there doesn't seem to be enough CPU power for all the 5 GPU's to reach their maximum speeds. I'm not mining with the CPU. It's just that the algorith is made in such a way that it also uses the CPU.
Has anyone found a way to unlock the rest of the cores, through some bios modding or some hidden option inside the 300 other usless options inside the bios?

Look into bios there must be disabled cores enable option. I remember this option was on servers i could choose any core enable and disable in the bios.
