I'm currently manually overclocking my 9950X3D, and I have a really strange BIOS issue.

In the first picture, when CPU Ratio Mode = All Core, I can manually enter the CPU clock ratio without any problem.

However, as soon as I switch CPU Ratio Mode = Per CCX (second picture), the CPU Clock Ratio option disappears completely.

Previously, when I selected Per CCX, the BIOS would automatically show separate options for:

CCD0 Ratio :

CCD1 Ratio :

so I could set different multipliers for each CCD.

Now those options are completely gone.

Here's what I've already tried:

  1. Updated the BIOS to the latest version.

It didn't fix the issue, so I flashed back to my previous BIOS version. Still exactly the same problem.

  1. This actually happened on older BIOS versions too. I have several BIOS profiles saved in Favorites for overclocking. Oddly enough, depending on which saved profile I loaded, the Per CCX (CCD0/CCD1 Ratio) options would sometimes appear and sometimes disappear, even on the same BIOS version.

  2. I've cleared CMOS countless times.

No difference.

I have no idea what's causing this anymore.

Has anyone experienced this before or knows what BIOS setting controls whether the CCD0/CCD1 Ratio options appear?

I'm really stuck and would greatly appreciate any help. 🙏

BTW my mainboard is : GIGABYTE AUROS PRO ICE REV 1.0
