Hello,

A lot of us here have been dealing with BSOD watchdog stability issues with Asus X99 mobos (running windows 10) with it's PLX feature that prevent us from using any of the Cuda 9 drivers. Nvidia drivers are to blame and they themselves have admitted to this non-app-specific problem . Would it be possible for Otoy to report this as well to add more pressure? I have already contacted Asus , and I'm trying to get everyone together here, and on the RedShift forums to keep adding support ticket, as they are dealing with this on their end as well. A large number of us use these boards because they have been highly recommended across all forums and have not had a problem until somewhat recently. I literally clean installed every single driver since then, and still only able to use driver 382.33 which is very old.

Open Issues...
"Random DPC watchdog violation errors occur when using multiple GPUs on motherboards with PLX chips. [2079538]" -Nvidia

http://us.download.nvidia.com/Windows/3 ... -notes.pdf

“We can confirm we do have a bug tracking this issue and we’re currently investigating. Although we have not been able to trigger the BugCheck “DPC_WATCHDOG_VIOLATION”, just system freeze/hang when there is high DPC latency. This was tested on ASUS X99E-WS with 4*GTX1080Ti. We are conducting more tests but the freeze/hang observed will be investigated by our development team."

I'll be damned if I can't use Octane 4! :)
Thanks guys!

PUSH PUSH PUSH

Same setup here. Same issues. Talked to a lot of people aound the globe consisdering these problems. Always comes down to the PLX chips.
Great idea. Maybe otoy and redshift both could report and directly contact nvidia.
This would be huge.

Best regards!

Because of this issue I had to quit to use Octane Render. I had to switch to another NON GPU render engine, purchase new licenses, and a new CPU node to speed up the rendering. This NVIDIA shit (please allow me this word in this context) it has already costed be thousands of euros.
I have no expectations that this will be fixed in the near future.

We've spent money, invested in hardware and licensed software.
This is not only affecting my business, but also Otoy's one.
Can we have a statement from an official Otoy representative about this issue?
What are we supposed to do as licensed customer which can't use the product anymore?

Same issue here!
Octane is pretty much impossible to use when rendering out image seqencies right now.
126 frames and then crash. 40 frames and crash....and so on.
I'm on 391.35 which seems to be the most stable 39x driver for me.

Nvidia really need to improve their QA work on drivers.
I wonder if the quadro drivers are equally bad.

same here! random bsod, with any drivers past 382.53
we need a solution, we invested a lot money in software and hardware and countless hours learning octane.
sorry but we cant just stay quiet.

so far the only things that helped a little is move displays to the 2nd or 3rd GPU
and change tdr delay to 60 seconds.

but the issues are still here

I've un update for everybody affected with the issue.
Puget Systems is handling the bug management directly with Nvidia and they have got the following update:

Update 6/13/2018

Nivida has stated that the watchdog BSOD w/ multi GPU on X99-E 10G WS is now a "blocking issue", which means they cannot release a new driver unless it contains a fix.

 For further information check the original post:

BTW, thank you OTOY for ignoring us.

Hey Guys!

It would be great if anybody who has any news on this topic could let everybody know.
I myself will keep you posted.

Best regards!

OTOY does not ignore You by any means, this is know issue, but at the same time it's under NVIDIAs, Microsoft competence.

W7 by the way are quite a bit more stable & some users already pointed that amount of BSODs were minimized.

Guys would be very helpful if You would list Your configurations (Hardware + OS + drivers) as we noticed that there are systems without PLX chip that are influenced as well.

Running an X99-E ws usb 3.1 here with Windows 10 and the higher the driver used, the faster the crash seems to happen. This happens as well on ASUS X99-E-10G WS. The funny thing is that this is the exact board Nvidia uses in their quad-gpu DGX workstations with no issues (not running W10 obviously). Slowly going down to the 38X branch to test stability. As of 398.36, this will happen at boot sometimes, and even faster once windows 10 initializes is main UI after logging in.

Photoshop as well as other apps appear to suffer from this as well (no bsod, just random memory leaks for CUDA apps), so PLX (the company who makes the onboard PCIe switches) and nvidia need to collaborate to solve this. I am on the 390.xx branch and this happens less frequently, so will likely keep going backward to find stability. Props to the post by ThomasHeun90 on the stable 382.53 driver to date.

Downstream port containment issues are scary and the driver is to blame mostly. Lets hope Nvidia fixes this!
