    Default EP45-UD3P Stability Issue ???

    I'm wanting to tweak on my memory but I'm not sure my system is stable.I ran Prime 95 blend for 10 hrs.(no errors).I ran OCCT 2 times(no errors).I noticed I had voltage drop on the 3,5,and 12 volt readings.I just want make sure my system is stable before I place a thread in the memory section.I also ran Memtest86+ 4.0 twice (no errors).Any help would be much appreciated.

    How much drop you have on the voltages?
    Any questions you have you can post here, we do memory too.
    If you post your settings we'll be able to comment about them. Use a template from this post or the one below.
    For the memory post a screen capture of MemSet main(click >>) and SPD(click spd) windows.

    Settings looks alright. Did you have to use the CPU/MCH Clock Skews at 400 FSB? Usually they are only required at higher FSB frequency.

    My oppinion is use XMP if you have it, profile1 or profile2, and leave timings on auto, at least the advanced memory timings.

    See how low can you set Static tRead Value(a.k.a tRD, Performance Level in MemSet) for both channels, for better memory performance. At 400FSB 8 or even 7 should be possible. Stability test will be needed after changing them.

    Thank you very much Chike.I don't know if I need any settings on the CPU/MCH Clock Skews-I was going off settings LSD gave to joynrg 12/16/2008 for OCing 4.0 and above.The title on the thread was:Please help me overclock my E8600 with EP45-UD3P Mobo.I'll make the changes you recommended - I'll run prime 95 blend for 12 hrs. - Run occt for 3 passes - Run Memtest86+ 4.0 for 3 passes.If I need to do something different please let me know.I really appreciate your help.(ps:I'll get back to this thread soon as I complete the test)

    These are the changes I made in the BIOS:Changed CPU/MCH Clock Skew to 0ps---Changed Memory Profile (X.M.P.) to Profile 1---Changed tRAS to 15---Changed Static Read Value to 7---Auto everything Advance Timing Control.I ran Memtest86+ for 3 passes (no errors).I ran OCCT for 3 passes(no errors).I ran Prime95 Blend for 3 hrs-then ran it for 6 hrs.Everything seems to be workimg GREAT.Thank You very much for your HELP.Wibujo

    How high do core temps get during Prime96 or OCCT?

    While running OCCT the maxium temp was 49c.While running Prime 95 the maxium temp was 52c.While running Memtest the max temp was 50c.
