Why are GFlops so inconsistent? - Page 2

post #11 of 12
No higher vcore is needed to stabalise higher speeds, its impossible that more voltage will make a chip slower. On the other hand higher temps might bring instability which results in lower gflops, and those higher temps may be caused by higher vcore, if cooling is inadequate. I hit 77C tops, after 20 runs intel burn test, using 1.39vcore and 1.21. Vtt. Everything else auto. Bclk 190 x 21 via turbo enabled. Turning c states of stops it from going higher than 21 on an i5.

make sure you are running the same problem size all the time as different problem sizes lead to different results
