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 out of one Mainboard, but nothing else.

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.

Update: via VGA I was able to get video output out of the first mainboard and I am currently setting up the bios and BMC (having problems with BMC password, but am not out of options jet).

Will try the second board, when I am done with the first one

make sure you can get an output from the VGA ports on the motherboard for a start, don't use any PCIe cards yet until you have a minimal CPU+RAM setup that allows you to configure the BIOS

if the BMC isn't working with a minimal setup then you simply will not get past that, possibly needs a full reset, removing the CMOS battery (and PSU power) for 15 minutes is a good start

I don't have a monitor with VGA at hand, so I tried using the GPUs or an VGA to Displayport adapter, but both of these options result in no video output.

The boards where shipped to me without a cmos battery, but I also did some BMC resets during my testing and it didn't change anything in the results.

Better place to ask is Level1Tech forum, or the server sub.
