GPU Vega 56 not showing up in device manager

Hello,

I just bought two more Vega 56s, I installed the drivers seperatly by only having one card plugged in. It mines fine, but when I put multiple GPUs in, it only detects the one. What am I doing wrong? I uninstalled the drivers and installed blockchain drivers on both.

Thanks,

Ethan

I have a EX-B250-V7 Motherboard… I have it set on mining mode with 4g enabled. Not too sure what else to do :frowning:

Try this, unplug the one that is working and plug in the other one. See if it recognizes it. If it does. You may have a bad riser.

Both Work individually when I plug them in seperately , but just not recognizing them when both plugged in at the same time.
