Gflops degrading in Intel Burn Test... Why?!

[lanjiaozxx]

I have an i3770k overclocked to 4.5ghz at 45x multiplier, 100mhz base clock and 1.240v vcore. Everything else on auto. I have done a 25 hours stress test on prime95 and I would assume it's pretty stable as of now.

I did another test yesterday using IBT and here's the result.

My question: Why is the gflops decreasing as the test progressed? I did a 30 runs and it went down as low as 72 gflops. Any idea why is this happening?

Here's the temps when I run the IBT:

Thank you!

My spec:
i3770k 4.5ghz
16gb 1600 kingston hyperx
250gb ssd hyperx
GIGABYTE Z77 HD3
COOLED BY Cooler Master seidon 240m
600w xigmatek bronze

Thermal Throttling.

No, it's not thermal throttling. Your cores never went above 90C and Ivy Bridge starts throttling at 105C.

And I don't think your results are out of the ordinary. Pretty sure that each round of tests is different, and they get progressively more difficult for the CPU/RAM to complete.
