It seems that I have the same problem as described in the SPCR review:
At default fan profile it is rock stable during a Furmark stress test (also combined with Prime95). Unfortunately when I set a quiet temperature/fan curve it crashes the system after two minutes or so. Around 75-80 C.Typically I try to shoot for a standard GPU temperature of 85°C but unfortunately an odd bug that caused our test system to crash the moment the GPU temperature reached 77°C with the GTX 960. However, this seems to be an isolated problem as it easily handled temperatures of 90°C and above when tested in two different systems.
It's the same on last two driver versions. Any thoughts what can be done to fix this? My first idea was that maybe the poer section or memory section gets too hot, but if it's an issue that is present only on some systems, that it should not be the case.
My setups is as follows:
i5-4690k
Asus Z97 Pro
Asus GTX 960 Strix OC Edition
Team Vulcan 2x4GB 2400 MHz 11 CL
Be Quiet! Dark Power Pro 10 550 W
Crucial MX 100 SSD
WD Red 3TB
R5 case
Windows 7 Prof with all updates
