Blaaaaaaaah this motherboard
Now I can't even get past the Bios screen, doesn't even let me enter win10 with 0 GPU's installed.
?? Anyone
Mine was finicky until I manually set the RAM speed to 2133. Also if you use a single stick make sure it's in the 2nd slot from the CPU.
I can't even get the board to run with more than 4 GPU. If I add a 5th GPU then 3 of the 5 GPU's give error code 12 in device manager.
I have spent literally 3 days trying to get this working and I am sick of this motherboard already. I feel like I have tried everything.
Tried several bios versions, 4g encoding, PCI Auto, Gen1, Gen2, Gen 3, diff risers, swapped ram, swapped cards, changed order of USB risers, tried everything listed in this thread and nothing works.
And I have 2 of them.

About to just write it off as a loss at this point. All because I wanted to run 7 GPUs. Bleh.
