I have one of the Intel motherboards (S2600CP) with dual Xeon E5-2670 CPUs that are sold by Natex. It has six PCI-E Gen 3 x8 slots. I'm trying to run two GPUs in this board (GTX 970). I have a Rosewill 850W power supply, and the board is populated with 64 gb of RAM.
The longer PCI-E slot (x16) closer to the memory banks is not really usable since a graphics card with any length at all will not fit because of the memory banks below it will interfere with the card. This slot is only x8 electrically (with a x16 length), so it's not really any different from the two open-ended slots.
If I populate only one of the open-ended slots with a GTX 970, the computer boots fine. However, if I plug another GTX 970 into the other x8 open-ended slot, I get an error in the BIOS saying something like "PCI resource error 146." Has anyone ever gotten multiple GPUs to work with this motherboard?
