SuperMicro X11DPG-QT: which PCI-E slots for 2x GPU?

Peter83 · Mar 25, 2019

Hi all,
I’m want to put two GTX1080Ti into SuperMicro 7049GP-TRT (SuperMicro X11DPG-QT motherboard with 6 PCI-E 3.0 x16). There are 4 PCI-E slots dedicated for GPUs; two assigned to CPU2 (slot 6 and 8) and two assigned to CPU1 (slot 2 and 4). Looking forward to your advice on how I should arrange my cards and which slots to use?
I was planning to use slot 8 (which is the first slot out of the four, closest to CPUs) and slot 4 (third) to keep good ventilation.
Sorry if the question is naive or trivial but it’s the first time for me to install twin GPUs.

6 PCI-E 3.0 x16,
1 PCI-E 3.0 x4 (in x8 slot)

Literally any x16 slot. Testing yourself is the only way to learn.

Since it is a dual CPU system should I put one of the cards to a slot assigned to CPU1 and the other one to a PCI-E slot assigned to CPU2?

What is it you ate trying to achieve?

Games really are only single cpu aware.

Are you trying to SLI the cards? Won't work unless you driver mod/patch them, and then would need to be running of the same CPU

The machine will be used for computational purposes and it’s running under Ubuntu 16.04. Therefore, I’m not going to SLI bridge the cards.
