Quad 1080Ti + ASUS X299 + F@H > DPC_WATCHDOG_VIOLATION

It seems that a lot of GPU problems revolve around specific versions of drivers. Though NVidia has their own support structure, you can often learn from information reported by others who fold.

I can't speak to what you might need for rendering. We're a FAH support forum, and this discussion is rapidly going off-topic except if it's somehow related to FAH.

According to the best information we have, There was a problem is the nVidia 397.31 driver when running FAH (and BOINC, for that matter). OpenCL and CUDA computing works for a while and then dies. It was enough of an issue that nVidia released a hotfix version 397.55 which may work and 397.64 has also been released. Be sure to do a clean install.

If your 730 worked before, it should still work, but the 1060 is going to run circles around it.

bruce, this is a very special issue for people using mainboard with plx pcie switch chip PEX8747. There FAH crashes with newer nvidia drivers and last good version is nvidia 382.53

NEWS UPDATE

We are many professionals who, since last year, we are finding this problem.

In case there is anyone with any doubt we can confirm that the problem is the motherboards with PLX processor exclusively in a multi-GPU system.

The good news:

nVidia knows the problem and is working on it since version 397.93.

Code: Select all
http://us.download.nvidia.com/Windows/397.93/397.93-win10-win8-win7-desktop-release-notes.pdf


-----
"Open Issues in Version 397.93 WHQL
This section includes lists of issues
that are either not fixed or not implemented in this version. Some problems listed may
not have been thoroughly researched and, in fact, may not be NVIDIA issues. Others
may have workaround solutions.
► Random DPC watchdog violation errors occur when using multiple GPUs on
motherboards with PLX chips. [2079538] "
-----

The bad news:

The problem was not solved in version 398.11.

Code: Select all

And it still has no solution in the current version 398.36.

I recommend that those affected, before updating drivers, check the Release Notes to see if they have solved the problem.

Code: Select all
http://us.download.nvidia.com/Windows/***.**/***.**-win10-win8-win7-desktop-release-notes.pdf


Change the asterisks by the version number

Greetings.
