Acceptable Overclock?

[Rowan88]

Hi,

I was playing around a bit with my overclock settings as I was noticing some random blue screen errors and crashes, anyway after reformatting my PC and testing out my new overclock settings I got this:

Cooling Options: BeQuiet! Shadow Rock SR1 Pro CPU Cooler, 2x NZXT Case fans (top and rear), 2x Thermaltake Case Fans (front), NZXT S340 Elite Case.

Stock: 3.4GHz @ stock / GPU 975mhz
Overclock: 4.2GHz @ 1.185v / GPU 1150mhz


Results:
RealBench - Up to 4gb RAM, 1hour test max temperature was 69 degree
OCCT - Large Data, 1792mb RAM, 1 hour test max temperature was 75 degree.
Unigine Superposition - 1080p Medium (1299/2048mb VRAM) Min 29, Avg 36 Max 46 FPS, GPU 77 degree, 4914 Score


After these tests is it safe to assume this is a stable overclock to use and I should not have any problems using it like this?

Thanks

Sorry it was in my signature: Intel Core i5-4670K. I will set vcore to 1.25v and test 44/45 but im pretty sure when I tried before I was hitting max temps.

44 @ 1.25v restarted on OCCT about 10mins in
43 @ 1.25v had been running for around 3 hours then restarted PC


From here I don't want to increase past 1.250 with my current cooling so I will drop to 4.2 @ 1.250 and raise uncore to 41 @ 1.20 and see how that goes, then slowly lower both uncore ring and vcore volts till I get a stable 8 hour pass.
