    Vcore is at stock default, it may need some more, try 1.25-1.35v.

    Which test did you run (small/laege/blend)?
    Please post BIOS settings for the test.

    Try more vcore.
    If your temperatures permits, run IBT or LinX 1024-2048MB 5-10 runs, test. Expected GFlops are 24+, while significantly less or test fails you need more vcore, keep increasing up to 1.3v.
    If not, run small FFT for 2 hours first and increase vcore if it fails.
    And finally, 8+ hours Prime95 blend.

    I tried runnig linx like 10 times or so, with different vcore [1.250-1.300] and it failed every single time. Then I tried with ibt only with vcore at 1.300V and succeeded on standard but failed on maximum. should I try to adjust anything else besides vcore?
    Results of linx & ibt:

    Default Re: Overclocking E8500 on EP45-DS3

    GFlops looks OK at 24.9 IBT and 25.6 LinX, no need for vcore higher than that give those results.
    tRD 8 should be ok, but maybe need to be higher, try 9.
    Try ram at 2.12-2.16v, try MCH Core 1.24v and 1.28v, try VTT 1.26v.

    I am not familiar with dirt2, how do you mean twiches?
    I run DDR-800 with CAS 7 at 400MHz FSB bur i saw an early rebiew they required CAS 8 so I figured maybe CAS 5 may require 9.
    What are core tems during IBT?
    Have you ran Prime95 blend?
