Hello. I have ASRock B450M Pro4-f motherboard with Ryzen 9 3900x. This CPU has 5th core malfunctioning. It's able to boot OS if i disable this specific core in linux kernel options. I want to use Windows, in which same is tricky, if possible at all. Is there any way to lock or disable specific CPU core or CCX in BIOS/UEFI in this motherboard? |

Thank you for the replies, both were very helpful.
Indeed, in the manual there should be Advanced->AMD CBS->Zen common options->Downcore control. But on my system there is no "Zen common options" for some reason, so can't boot windows, so can't use ryzen master...
I think this is my option, now waiting for the answer from RMA team. |
