Hi! I have a ASUS Z10PE-D8 WS with one Intel Xeon E5-2687W V3 3.10Ghz and Corsair 1500 PCU. I have two Titan-X and one 1080 GTX.

I can only get two GPUs running i Windows 10 64-bit no matter what i do. Change postions or try different BIOS settings.
I also have an AMFELTEC rig, but my system wont find any GPUs with that either.

Do i have wrong MB/CPU to get more than two GPUs running? Any suggestions welcome before a set my rig on fire.

The one marked CPU_1 on the MB.

I have that MB but with 2 CPUs and all works fine (i have occupied slots 1,3,4,7) but frpm Manual description i think you can't use all PCI-E slots for single CPU , just liek RAM slots are spread among CPUs that's how PCI-E is also split between CPU 1 and 2.

Quote from Manuals:

2.5.4
PCI Express x16 slot (x16 link)
The onboard PCIE 1 and 3 provide one x16 Gen3 link to CPU1
(Auto switch to x8 link if PCIE
2 and 4 are occupied)
; The onboard PCIE 5 and 7 provide one x16 Gen3 link to CPU2. These
slots support VGA cards and various server class high performance add-on cards.

2.5.5
PCI Express x16 slot (x8 link)
The onboard PCIE 6 provides one x8 Gen3 link to CPU2; The onboard PCIE 2 and 4 provide
one x8 Gen3 link to CPU1. These slot support VGA Cards and various server class high
performance add-on cards."

I have the same motherboard with two cpus, I've had two titan X maxwell and a quadro K4000 working and now have one titan X maxwell and two gtx 1070s running. I feel your pain though I had to try multiple configurations to get both setups working. Its a frustrating motherboard I can't remember the slots I currently use but from the top it goes titanx then i have a single slot iofx pcie drive then 1070 and then 1070 if that helps at all.

Thanks for your input! I need to buy a 2500USD Xeon to get the same specs as the CPU i already have. It´s only money
