Are you sure it was your GPU that got fried? From experience it is always either the PSU or PCIE riser that will burn first. PSUs will pop because of overload and risers will burn because of poor SATA/molex connections.
Given that your GPU is only 1 month old i also doubt it would just spontaneously give out. Unless its a lemon. Could you provide more details to help us learn more?
Hi, pretty sure it is GPU, i will investigate it deeper later but riser/cables has no sign of damage, and GPU itself has strong strong smell... And yes it is only 1 month old.
Thanks everyone for advices, i will clear thing a bit:
1. All my rigs are NVIDIA based 1060,1070/ti,1080,1080ti
2. All set up to 73C max and ~65-75 PowerLimit (and actually running 55-70C)
3. Cards has a lot of space between 10-15 cm at least (6-7GPU rig is 90cm long)
4. Almost all risers are the same manufacturer and looks like pretty quality one. Thats why they are all the same.
5. GPU OC is +50 on GPU max and 300-500 on memory depending on stock clocks, but no extremes
6. PSUs takes up to 85% of their max from the wall, so if it is 1000W it takes about 850 from the wall (and thats gives + -10-15% beacuse of effeciency so it is about 750 actual load on PSU).
7. Maybe PSU load could be a problem, but they are all EVGA/Seasonic/Corsair and has some spare power.
8. All rigs are pretty stable, some may reboots each once 7-10 days, but if it happens often i look at them closer until they are stable.
So far that much from me.
Thanks everyone involved!
