Just updating this thread, I still have stability issues with Multiple GPUs enabled on my x99 WS-E motherboard. Nvidia still has this listed as a known issue in there release docs for the latest driver: 398.36

Check if your 2 GPUs are on PCI-E slot 1 and 5. In this configuration, each GPU will be attached to a different PLX PEX8747 PCI-E switch. If you've alread instelled the GPUs as above and it doesn't work, try Slots 1 and 3, i.e. on the same PCI-E PLX switch. My GPUs are installed in PCI-E slot 1 and 3. I could try switching to 1 and 5, but If I disable my non-display card, so far I have a stable system. I'd rather not switch all of my PCI-E cards around if I don't need to. Obviously I will do this if it helps Nvidia get to the fixing this. But right now in production this just isn't really practical at the moment.

this is not what I was hoping to hear. I have 6 machines built off of the x99 e ws and multiple GPUs. The problem does persist with less than 3 pascal cards, however. My system with 2 1080 cards still exhibits the same behavior. For now I will have to limit the system to one card and hope that it stays stable. As I need CUDA 9.1 for Octane render.

PC crashing - BSOD Watchdog violation 1x133 (possibly nVidia issue)

Recently I have built a 3D rendering station for a client of mine. The machine runs, but crashes about once or twice a day with a BSOD (watchdog violation 1x133. Blue Screen View mentions either nvlddmkm.sys or ntoskrnl.exe as culprit.

Things I have tried so far:

Clean install Windows 10
Clean install Windows 7
DDU removal of graphics drivers
latest nVidia drivers
older nVidia drivers
extensive RAM testing

Specs:

Asus X99-WS 10G E
Intel 6850K
7x Zotac 1080ti Blower Edition (transformed to water cooling)
64GB RAM
Samsung 960 Pro 512GB (system drive)
3x WD Red in RAID 0 (data drive)
2x Cooler Master V1200 PSU
Custom EK watercooling loop
Obsidian 900D
