I am totally off the deep end and don't know where else to turn for help/advice. I am trying to get 16 GPU's on one motherboard.
Hmmmm. Yet another crypto currencies miner. ;-)
Whenever I attach more then 3~5 GPU's to a single motherboard, it fails to post. To make matters worse, my post code reader(s) don't seem to give me any good error codes. Or at least nothing I can go on.
You should have at minimum 1KW PSU for this job. At least... I guess, even more (for 16 discrete GPUs) 2 x 1KW would be reasonable.

I am using PLX PEX8614 chips (PCIe 12X switch) to take 4 lanes and pass them to 8 GPU's, 1 lane per GPU. Bandwidth is not an issues as all my code runs native on the GPUs. Depending on the motherboard, I can get up to 5 GPU's to post. After many hours of debugging, googling, and trouble shooting, I am out of ideas.
At this point I have no clue. I think there is a hardware, and a BIOS component? Can you help me understand the post process and where the hang up is occurring? Do you think Coreboot will get around this hangup and, if so, can you advise a motherboard for me to test with?
Its been a long time sense I last compiled linuxbios. ;-)
Thanks -Adam
