Triple pro duo setup not booting

Hey guys, i am stuck with a strange problem that is probably not even the fault of the cards themselves but i hope maybe someone here has and idea how to troubleshoot next.

I wanted to have 3 pro duo Polaris in a server so it would have 6 physical GPU's.

All the cards work individually, they all work as a set with one other, they also work in all the slots.

But as soon as i install all three it wont boot.


The motherboard the asrock x399 Taichi with a 2950X just keeps cycling boot codes in a continues loop.

I already contacted there support but no response as of yet.

Cant get a screen nor bios so its stuck in the pre boot check.


Power is not the issue, i switched the PSU with a brand new 1300w.

Same problem.

if i install 2 pro duo's and a wx4100 it works, but if i take a third pro duo it goes haywire.

Hope someone has an idea what to try out next.
