Luxmark.exe crashing

Ok so when I run the stress test in RealBench I keep getting a black screen, the driver stopped responding message and Luxmark.exe stopped working.

My initial thought was instability, however with my whole system at stock I'd still get the same thing happening.

Anyway after much experimentation it turns out when I don't run certain monitoring software I don't get the crash.

Monitoring software such aida64 causes the crash. When I close aida64 and then run the stress test, RealBench shows "Result Hash Match!"

So my question to you is, is my system unstable? Or can I just simply assume for whatever reason that certain monitoring software causes a conflict?

Surely if my system was really unstable I'd get the crash regardless? But the other side of me thinks that I should be able to have monitoring software work in the background .

I'd be curious to know if this is a known bug, perhaps monitoring software polling gpu readings causes a crash in luxmark, but in saying that EVGA precision X runs fine in the background.

Here goes an update...

I have been redoing my OC in BIOS starting from default settings... well, spent a lot of time at default settings...
Luxmark.exe was crashing with the nvlddmkm event all the time...
Just could not commprehend - RB benchmark is passing, 3DMark FireStrike is passing at every level, even the new Superposition has passed with no issues... then RB stresstest is crashing again...
Start thinking that this can not be a hardware error... something is messing up RB - so started to kill applications running in the background...

And I have found something: STUPID GPU TWEAK II!!! Two Asus (related) softwares don't play nice with each other on an Asus board...

Well, before I noticed the RB stress-crashing problem, I have set GPU Tweak II to start with the OS, minimized to be available if needed... I've had a custom fan curve setup, more aggressive than its default - and it was doing it job as shown with other benchmarks...

If I set GPU Tweak II to open only when I click on it, set the max fan speed (tried only this), then close it - the fans will keep the setting, and RB stresstest will go on for at least one hour (the max I had time to try) without problems! :cool:

Edit: I never used OSD on this system...

You have a very good config,
I'm never tried stress test without MSI Afterburner, I also use it for the speed of the fan,
And for overclock I use a script that works with Nvidia Inspector,
As soon as I can I would do a test without msi and I would post the result.

Use the MSI Afterburner to speed up the fans (I am doing 100% fan speed when benchmarking), then close it - make sure that it is not in the System Tray...

I removed "MSI Afterburner" from auto startup,
I set the fan speed to max with nvidia inspector,
I did a stress test of 2 hours, no problem appeared from the beginning to the end,
Thank you for the information,
Now we need another software for the adjustment of the fan...

Nah, you can still use the MSI Afterburner if you like it - do your setting, hit apply, then quit... it will hold the settings...
Again, just make sure that you un-check the thing in its preferences about keeping it in the System Tray, and for that matter, also un-check the start with OS thing...
That way it's there when you need it, but won't interfere with RB...

I tried but whenever I leave "MSI", the fan speed decreases

Oh, I see... then maybe try GPU Tweak...

Zka17 can you try and test if this also happens with GPU Tweak monitoring disabled?

That will take a while... I took apart my TestBench and my new system isn't ready yet. Will do as soon as possible!
