Disable specific cores on r9 5900x

[Devryd]

Hi, 
For an OC competition on HWBot, I need to validate the highest CPU frequency on my CPU. Is it possible to disable the 10 worst cores of my CPU and just boot with the 2 best? If so, how do I do that?

Oh I was just curious that's all.

 

You should be able to disable cores and SMT in bios. However, I don't think you can shut off certain cores and leave others on. 

 

For max clocks shut off all but 2 cores. Run core 0 and 1.

Actually, you can disable specific cores in ryzen masters. I disabled all, but the best core of each ccd and managed to validate 5100MHz on CCD 0 core 2

Just about maxed out there for ambient cooling. 

 

Cpu-Z validation should be done on core 0. Since it's the only core you cannot shut off.

Oh, I don't use Ryzen Master. I figured bios settings.

 

5.1ghz is pretty good though. Have you considered chilling? Dry Ice maybe?

The competition is on ambient air, so this would be unfair
