Like many here I have been having watchdog violation errors over the last few months with the most recent Nvidia drivers (prior to then rock solid machine). My machine is basically unusable with any Nvidia driver other than 382 or prior. However, with the massive improvements of Octane 4 I can't just sit on driver 382 as it requires Cuda 9. I think I may have read just about every forum on the internet regarding this issue trying to find some fix. I have read the Octane Render public group threads on this, the Octane reddit forums, the Redshift forums (yes they are having this problem as well), the Microsoft complaint forums, and some fairly obscure hacker forums.
What appears to be common to everyone having the problems is an Asus WS X99 board of some flavor, in combination with 4 cards with some Nvidia driver after 382. My build is below. I have updated bios, Windows, Nvidia drivers, tried different CRD versions, Windows fresh installs, played with bios setting, changed the Nvidia power consumption defaults, changed Octane versions, updated random drivers of every program on my machine and a other things as well. Nothing will give me a stable build, except Nvidia driver 382. I would greatly prefer not to go to Windows 7, as I have other things that need Windows 10.
So what can I do? I can wait and hope that Nvidia cares enough about our little niche world to spend the time to address this. I can hope that nonexistent support at Asus would take the time to address this. The only thing that seems to be a real fix is getting a different motherboard and just embracing all the plug in reinstallation's issues.
For people with 4 1080tis running well on their machines with the latest drivers, what is your mobo (especially x99 mobos)? I know this is the expensive solution, but I just am tired of this issue and want something that works. Any other ideas? Thanks.
X99 E WS/USB 3.1
64gb DDR4
4 1080ti Hybrid
Windows 10 1709 (tried many others)
Nvidia 391.05 (tried many others, 382 works)
Octane for C4D (r17 or 19) 3.07 R2 (and tried 3.08 and 3.06)
