Daz Studio dual RTX Titan causes abrupt computer reboot.

Hi all,
So I’ve encountered a rather nasty problem with Daz studio. It started after I installed Nicehash to mine on my computer. It’s taken me a few months to notice several patterns and for the life of me, I can’t get it to stop now- short of reformatting. I don’t want to reformat due to how much customization I’d have to go through…but that’s looking like the case. I’m hoping that in the next 24 hours or so, someone online can say ‘hey, do this’ and it’s fixed.

Essentially, every time I try to use both of my RTX titans to render out an image from Daz studio- at some point in the render, it triggers a system restart. No error codes, no BSOD, an abrupt restart as if you pressed the restart button on the front of the machine. It's so abrupt that event viewer doesn't even get the chance to display a log until after the system reboots.

This problem started after I started using Nicehash to mine as a passive income. Now most people would say ‘uninstall and you should be good.’ Yeah, I did that and it hasn’t solved the problem. Nicehash isn’t on the system right now and it still abruptly reboots.
Faulty hardware? Not likely. I’ve stress tested the CPU, GPUs both individually and together and memtested the RAM and the PSU indicates all is good. I've stressed the entire system and nothing caused any issues. Essentially every test gives me the green light. So my only possibility is software- short of buying new parts to test...and I don't have that kind of capital.

I’ve uninstalled and reinstalled Daz three times, no go. I’ve updated drivers, taken off all software that I installed in the same month as this problem started. I've taken off all Visual basica C++ packages and let Daz reinstall what it needed. No go.  I’ve posted this in multiple facebook forums and those that responded, have run out of ideas because I’ve tried everything they’re suggesting.  I don’t post in forums or on facebook unless I’ve exhausted every option short of a format- I strongly, strongly believe in using google before asking for help.

These are my specs:
AMD Ryzen Threadripper 1950x (no overclock)
X399 Taichi motherboard
2x RTX Titans (no overclock)
128 GB of RAM (quad channel)
Corsair AX 1500i PSU (1500 watts)
Windows 7 Ultimate x64 SP1 with all updates.

For various reasons, both personal and professional, I will not migrate to a newer version of Windows nor Daz studio.  I’ve run Daz Studio for 3 to 4 years prior to Nicehash with absolutely no issues. I’ve run up to 20 instances with no issues. I’ve rendered out 6 different images across 6 different instances with no issues. I’ve run 48 hour renders a maximum GPU utilization with no issues.
But now…If I use both GPUs, it reboots. If I use a singular one, it doesn’t (oddly). I bought these GPUs to speed up renders and now I can’t use them both. I’ve also tried two different sessions of daz studio, one for each card, still reboots.
Something has changed on my system and I can’t figure out what it is. If no solution is found by Thursday night, Friday morning I start fresh and spend an entire day rebuilding from the ground up- testing Daz studio's rendering until I find what threw a monkey wrench into the mix...then remove said wrench and ban it from my computer.

Please admins, approve this post rather quickly- I really want to get back to rendering...i'm starting to have a back log of ideals, projects and things I want to test and try out.

A system restart nevertheless sounds like hardware - Iray is very demanding so it might well be heat or power issues causing the restart. It's possible that the stress of the mining aplication was enough to strain soemthing so that it became more failure-prone, but it may simply be a matter of the age of the components.

Are you trying to run your crypto-hashing server software at the same time?

https://en.wikipedia.org/wiki/NiceHash

Judging only by what I've been able to google in the last few minutes, I wouldn't trust NiceHash.

You will most likely not be able to run both DS and the mining server at the same time.

Yes, it's one of multiple things I've tried; I used Cinebench and Prime95 on the CPU. no issues.  I used OCCT, furmark and Nicehash on the GPUs. the stress testers came back fine, nicehash ran for 7 hours without an issue.  My system only abruptly reboots with Daz Studio renders, which are less intensive than mining.

Edited the quoting bracket. I forget it's a W.Y.S.I.W.Y.G. environment.

 

No. I'm not trying to run them simultaneously- one card mining, one card rendering. I did so for testing purposes, but I don't do it because I want maximum performance: two cards for rendering or two cards for mining.

As for the trust with Nicehash- they have been more transparent about things than 99% of the other companies that I've dealt with the last 8 months. Bungie had a catastrophic season release, leaving hundreds of thousands of people in the dark while they repaired an 'oopsie' because they literally didn't test something (and they threatened to ban anyone that used a third part fix that worked, vs their eventualy update that half worked). Microsoft quietly rolled back various updates and OS upgrades due to catastrophic data failures, losses and computer crashes.  Nicehash is the only company that I've encountered that is 99% transparent- even to the point of where they wrote an article on their CEO/Founder, a convicted white collar fellon whom makes sure the strictest of security measures are used (including two factor authentication using a random key generator powered by another company).

I could run both Daz and the mining software, but i'd rather not for performance reasons...I did talk to someone on facebook who accidently did that at one point with a 3080...everything was extremely slow.

I currently have a working theory in place and it's sustained several renders thus far.

Well, it turns out that A- the video cards no longer liked the dynamic voltage/watt changing being supplied through daisy chain PCIe cables or B- the little 'u' part of the daisy chain PCIe power cables weren't functioning properly. Why they worked with Nicehash but not Daz studio, beats me. I swapped those two out for 4 one to one cables and things are back to normal.

ie, my bad for blaming Daz Studio.  this thread can be locked if necessary since the problem was solved.
