Back story:
I build used gaming rigs on the side from used parts. I sold a guy a machine and he reported artifacting issues with it in games. Games would crash, hang, stutter, artifact etc.
He was pretty decent and supplied various videos of it failing, I tried some things over video call with him and had some success but eventually the problem returned.
Since I'm not out to do people out of their hard earned cash I replaced the whole machine and took the faulty one back. I suspected GPU like most probably would so was interested to confirm it.
The Hardware:
Zotac GTX 1080ti AMP! Extreme Core Edition
7700k, 16GB, MSI B250 (original 'faulty' machine)
8700k, 16GB, Gigabyte Z370 (my test rig not my personal gaming rig)
Corsair RM1000x (test psu I use)
When I originally purchased the card:
The gpu is a Zotac GTX 1080ti AMP! Extreme Core Edition. I tested it at the buyers address using Furmark till it reached its max temp during the test and monitored it for a few minutes followed by a few runs of superposition. It had no issues. I paid + left.
Back to testing today:
Back with the faulty card/machine (7700k, 16GB, MSI B250).
Fresh install of windows / drivers / BIOS update etc, start testing the card.
Furmark passes without any issues.
Superposition passes without issues.
I'm wondering how to replicate the issues he showed me.
Unigene heaven is where the issues start.
1min into loop (not benching) exhibits the same issues, artifacts, stuttering, momentary black screens and the application eventually crashes to the desktop.
I swap to a known good Corsair RM1000x psu and the problem persists.
Swap the card to another machine (8700k, 16GB, Gigabyte Z370) and the problem persists.
Swap the 1080ti for a 1070 to cross reference and the problem is gone heaven runs fine continuously.
So I'm 99.9% the 1080ti is faulty.

Questions:
Why is the card not failing in Superposition or Valley or OCCT but failing in Heaven?
What is different with heaven vs all the other unigene benchmarks?
Why is Furmark not failing? (I've always assumed Furmark to be brutal and most likely to exhibit errors)
Have I just been lucky all along? I've built many many machines. Have I unknowingly omitted crucial testing when purchasing used GPUs?
Is this card even faulty? (you know when you've been testing something strange for so long you don't even know what your name is any longer... I think that's where I am)
Just looking for thoughts on it all as I'm sat here watching Valley benchmark pass loop after loop at ultra settings with no issues and that 0.01% of doubt is creeping in telling me the card is fine but obviously something is wrong as heaven is exhibiting all the signs of a faulty gpu.
Edit:
I've just found this. I shall do some testing.

heaven is not a tough benchmark. The GPU will consume far less power then in other benchmarks or the games you tested. less power consumption also means that your gpu runs colder. both will allow the GPU to clock higher than usual, thats why it crashes.
solve this problem by overclocking via the curve editor in MSI Afterburner. this way you can forbid the gpu to clock very high like it is happening in heaven benchmark.
