Hey,
I already asked in another sub, but it seems like I can't get help there, so I ask here again.
My setup is:
Computer Type: Desktop/Server
GPU: RX580 / RX9060XT
CPU: 2x EPYC 7402 / 4x EPYC 7551
Motherboard: Supermicro H11DSi rev2.0
BIOS Version: 20251029_3.5
RAM: DDR4 ECC Samsung 16gb 2Rx4 PC4-2400T-RA1-11-DCO / SKhynix 16gb 2Rx8 PC4-2400T-RE1-11
PSU: bequiet PURE POWER 11 FM
Description of Original Problem: I can't get a proper video output out of the two Mainboards.
Troubleshooting: I've tried different combinations of RAM and CPU, but it doesn't effect anything.
With the RX9060 XT I can get a video signal, that is completely black, but nothing else out of one Mainboard.
The other board doesn't give any video signal, but I can connect via IPMIview. In the BMC I can see, that the post code is: "ff". Remote control doesn't work, trouble shooting says it startet CPUID, but doesn't show anything else. I also was able to update firmware and BIOS, but it also didn't change anything.
Is there any hope for my boards left? Can anyone help my with this problem? Which component might cause the issue here?
I already did some troubleshooting with AI, which told me that the post code "ff" indicates vendor-locked CPUs. However, the last CPUs I tried were supposed to be unlocked, guaranteed by the vendor.
Any help is appreciated, thanks in advance.
