[SOLVED] Strange issue with i7-6700 and GTX cards ?

[wasiup]

hi.
i am not a beginner in hardware, but i have strange issue and need help to resolve it.
i have i7-7700k and i7-6700 both tested on the same board msi z170a gaming pro carbon.
i use two benchmarks to test stability and the results are:

asus real bench stress test 30 min: i7-7700K + gtx 660 - pass
asus real bench stress test 30 min: i7-6700 + gtx 660 -fail, crash after 1-3 min
asus real bench stress test 30 min: i7-6700 + gtx 2060 - pass
furmark: i7-7700K + gtx 660 - pass
furmark: i7-6700 + gtx 660 - fail, crash after 20-40 min
furmark: i7-6700 + gtx 2060 - pass

it's strange. it seems that i7-6700 has some compatibilty issue with gtx 660, but i7-7700k runs with it flawlessly.
which component is faulty: i7 6700 or gtx 660? any idea how to check it?

tried to update the bios to the latest, and force the pcie to pcie 2.0?

Usually i do DDU before changing gpu and install the gpu driver with the gpu that's inserted (even if the same nvidia but different series) since their installation differs.

Based on your results, the corporate seems to be the gtx 660. Furmark is fine for testing gpus. It should fail relatively quickly if it's defective....
