Low IBT GFlops - is it a problem?

post #1 of 6
Thread Starter 
So basically whenever I run IBT I get around 60 GFlops. People on other forums keep telling me I should be getting around double that so around 120 GFlops. I have my CPU overclocked to 4500Mhz and using around 1,4vcore. It is 100% stable using IBT and other stress tests.

I was just wondering, even though I'm getting half of the GFlops, is my CPU still performing as its supposed to?

You need to have SP1 (service pack) for windows and also the newer version of IBT. This enables the use of AVX (the advanced vector extensions) which double the floating point throughput of Sandy Bridge CPUs.

Yeah, installing SP1 and the newest version of IBT brought my GFlops way up... although, I think they should be a bit higher. I'm getting 105-116 at 4.8GHz

Oh, well that solves it.
I don't have SP1 installed.

Installing it now, lets see if it makes a difference.

Yes, do that. AVX will double your gflops. Cheaters.
