    Run IBT. See if your proc is stable. Also what your GFLOPS are. ( Run the standard test) You should get 27.5+ GFLOPS at that speed. Anything less and your vcore is too low.

    You could have a chip stable at a low voltage, but drastically reducing its GLOPS output by under-volting.

    For instance. I had my E8400 at 1.30v Load and was only pulling 26 FLOPS. I did nothing but raise my vcore to 1.328v and now Im pulling 28.2+ GFLOPS.

    And IBT testing means really little I can IBT test 10 passes even and get stability at max setting but it won't run on 6 hours of prime 95 blend
    So for me IBT is not very for sure

    My comment has nothing to do with stability. Its to see if your E8400 at 4.0Ghz is actually performing like it should. If you run the "standard" IBT and get less then 27 Gflops, you need to bump up your vcore slightly.

    If you aren't getting 27+ Gflops at 4.0Ghz, then its all glow and no show. You might as well clock it back down to 3.6Ghz. Cause thats how your chip is actually performing. Make sense?

    Looks good! Bet if you bump your vcore a notch or two you might get to 28 Gflops :P

    Thumbs up Re: Ud3p & e8400

    With a dual core cpu, using THREADS = 2 will increase the GFlops score and complete the test sooner.
    With 4GB of memory, I test my 32-bit w2k o/s using MEMORY = 2047 for a more rigorous test.
    10 loops instead of 5 loops is a more thorough test.
    Note: I've passed many IBT 10 loop tests, only to have Prime95 tests fail, usually after 4 - 8 hours or more.

    A 30 - 60 minute run using OCCT PSU test is another good stress test that will really heat up your system.

    **edit** Your current memory settings are somewhat loose which means that your overall system performance is about 1 - 3 % lower than optimal.
    I wouldn't tweak your memory settings until you've reached your final stable settings.
    Naturally you will need to repeat your stress tests when performing your memory tweaks.
    Looking good so far.

    As an example. I bumped my cpu vcore "1" notch in the bios and look and increased the Stress Level for a more rigorous test :P

    I got +0.5000 Gflops increase!

    So don't be afraid to bump your vcore a bit, as long as temps are good. Then run IBT to see if your Gflops increases. Then once you notice your Gflops are NOT increasing anymore. Then go back into the bios and drop your vcore "down" one notch.
