Only 1 GPU is detected, but I have 2x 1080ti. Not present in IOMMU groups.

I was running 1x 670 and 1x Firepro.

I swapped the Firepro for a 1080ti and made sure I had it working.

Then swapped the 670 for another 1080ti. 

 

Upon reboot, the second is not detected (which was tested first) and the first is detected.

 

These were both intended to be passed through to a VM.

EDIT ---- I'm blaming lack of power. When building this server it seems I didn't intend to get 1080ti's.

 

EDIT -- I would have been wrong. Seems I didn't click the card in as it didn't show up solo either, which it did originally. I've also switched to a 1060 and 1080ti as power may still be a problem but wasn't the problem.

I did get it working.

 

I placed the first card in the pcie slot 2, I'm sure it clicked in but maybe not it seems, while keeping my old gpu working in slot one for dumping the bios of the new card and testing. Once I placed the other card in slot 1 somehow the slot 2 card had come out of the pcie slot a little and this was no longer visible until I had removed the top card.

 

But in all this, I noticed I only had 650w, not an 850w power supply. So I swapped one of the cards with another pc in the house, now the system has 1060 and 1080ti.

 

-PSU isn't good enough for running both, it would manage since I'm limiting their power usage but as the server is transcoding and cpu often used. I need to replace the PSU to run both in this system.

-Space wise, I had to remove harddrives cages from the system to place the cards in and replace them afterward.

 

Overall not what I had planned, and it really makes a difference the size of the 1080ti vs 1060 mini.

Also, I could not dump the vbios of the 1080ti, GPU-Z didn't support it. I downloaded one and edited that instead.
