CPU cores disabled after BIOS update?

Hello,

I have the AsRock Steel Legend B650 Wifi and today I updated my motherboard to UEFI version 3.16. After closer inspection, I noticed that XMP is disabled for the RAM and only 6/12 processors are active. I have a Ryzen 9 9900x.

I tried to select the 12 cores via msconfig under Advanced, but only 6 are displayed.

I have seen the XMP for the Ram is deactivated

Normally after a BIOS update. The BIOS is returned to the original state (you don’t know if the old settings are running with the new version)

and also only 6 / 12 processors are active

Probably you have only 6 cores with 12 threads. Zb the 9600x would be such a candidate.

I have over msconfig over Expanded tries to select the 12 cores

Keep your fingers off.

I have the Ryzen 9 9000x.

See if it really is a 9900x

There is no ryzen 9 9000x. There is a ryzen 9 9900x – and yes it actually has 12 cores.

So much for that.

with the Ryzen Master

Well, that explains…

What is called gaming mode is questionable

Probably improves the single core performance. The more important in gaming than the number of cores. But it’s only a presumption on my part. Had no ryzen 9xxx in the hands.

All right.

Well, the main thing you have is the mistake.

At your point, however, I would uninstall ryzen master and then reset the BIOS again. This usually makes more crap than it helps.
