Overclock Validation and testing (Intel Core i7 5930K)

[gabby131]

Greetings!

I am in need of your assistance....
As per my sig, for quite a while, my 5930K has been overclocked to 4.5 ghz @ 1.275 volts.
It's doing fine for as long as I have it on this setting on games and a little video rendering.
Running cool at 70 degrees C at max and average of 65 degrees C.

This one night, I randomly checked to see what my current Cinebench R15 score. I have records kept but figured a most updated one will be best.

I ran the benchmark and as the image is being rendered, the image momentarily freezes for about 2-5 secs then continue. I confirmed this is happening almost 4 out of 5 runs. The application nor the whole system crashes but just the freeze on the image.

Does this mean my overclock is not as stable as I assumed it is?

Months back, my OC validation includes 30-60 mins of ASUS realbench, 60-120 mins of AIDA64 (CPU, CPU/RAM/FPU testing), 30-60 mins of Prime 95, 60 mins of OCCT, and 1-4 hrs of Intel XTU CPU/RAM stress tests - I have no luxury of running the tests on extended periods. I even have the system doing some protein folding via Folding@Home for 8-24 hrs a day. With my setting (4.5ghz@1.275v) all test have passed with no errors, freezes, nor reboots/BSODs.

I greatly appreciate your input.

Best regards,

I used to have this problem with my 4670K at 4.5 GHz and the Passmark CPU benchmark fluctuating around, the only thing that would make it crash incidentally was extended periods of CS:GO. Both were fixed by raising the voltage from 1.30 to 1.32V, so I assumed it was just correctable micro instabilities or something. MAybe you're getting the same thing, try raising the voltage to 1.29 or 1.30 and see if anything changes.

Dayum.....yep, that makes sense. However, I needed more voltage to remove the freeze. It was able to run Cinebench without the freeze at 1.32v. As expected, my temps got higher ('bout 70-75 degrees C average on extreme stress tests) but still in my comfy zone.

I got a WHEA_UNCORRECTABLE_ERROR BSOD on 15 mins of OCCT but was fixed when I change the CPU Input voltage back to default (Auto).....

Thank you for your assistance.
