    Default E7400 Gflops

    What kind of Gflop readings are people getting from E7x00 series processors. I just oc'd my secondary system (E7400 & EP45-UD3LR) to 3.6 GHz (343 * 10.5) and I get results like this
    Attachment 2630

    My quad system pushes about 14 Gflops/GHz, is 6.5 Gflops/GHz ok for a dual core ?

    at those speeds with that cpu looks about right. If you want to make sure they could to right by rerunning the program. If your o.c was not close to stable the program wont load the cpu properly and would result in low or abnormal numbers. Or down clocking or push it harder and see if the numbers move with the speed.

    My I7-920 at 4.5ghz is getting around 63-65 gflops using full memory.

    System seems quite stable, passed that Linx run, passed 12 h of Prime95 small fft's and it's now been running 10 h of in-place fft's, no errors. Gflops do change with oc level but Gflop/GHz ratio is constantly about 6.5, I am mostly interested in hearing if that is normal level of performance for E7x00 series.
