Zenith II Extreme - Load VGA Bios
I'm currently trying to run a 3 GPU setup with my zenith board to pass through gpus to virtual machines via unraid.
I've had no issue with 2 GPUs thus far + a mellanox 10GBps card, however, whenever i plug in more than 2 gpus of any kind i get a d4 bootcode and a load vga bios error.
From what I can tell, this isn't the only time a Zenith board has exhibited these issues. Scouring ASUS's forums, it looks like people with previous gen TR have had this boot code error for sometimes different reasons.
Does anyone have some sort of idea how to go about troubleshooting this? I've tried 5 different combinations of gpus in different PCI express slots (in groups of 3) with and without riser cards to no avail. I'm hoping I'm just doing something wrong here, but I'm worried that I'm at ASUS's mercy right now for some sort of bios update to fix this issue.
If it helps here are the specs of my setup:
AMD Ryzen Threadripper 3960x
asus rog zenith II
32GB G-skill flare-x
128 GB m2 ssd
500 GB samsung 970 plus
1 TB sabrent m2 ssd
8 TB WD white drive
Asus gtx 2080
The different combinations of GPUs I've tried are as follows: rtx 2080, gtx 1070, amd 6850, ati 5670, gtx 1030. Any combination of 3 seems to prevent my ability to boot showing boot code d4 and load vga bios.
