    Ok read edit put that number in your bios...if test fails raise one or two notches. If that fails raise up MCH core one notch. But it should work on the stock speeds.

    failed at 3minutes 33s for LinX
    and 65 seconds for IBT

    Could you run P95 small FFT's and see what you get. Also you need to check Round off checking under advanced tab if you didn't know.

    Please post your current bios also.

    Also lifted from a thread of mine on Prime 95 tests and what they mean by Psycho101

    Small FFT
    This test uses data that fits completely into your CPU's level 2 cache, it stresses the processor intensely but does not stress the RAM or the link between the RAM and the processor. It will error out because of:
    Not enough vCore
    Possibly low CPU Termination (VTT)
    Possibly low/high CPU ref
    Possibly low PLL (clock generator) voltage

    Large FFT
    This test uses large "pieces" of data that require information to be moved in and out of RAM quite intensely to constantly feed the processor. The data in these calculations doesn't fit completely in CPU onboard cache, so the work load on the MCH and RAM is huge. It will error out because of:
    Not enough vDIMM (RAM voltage)
    Not enough (and rarely too much) MCH core voltage
    Incorrect MCH ref voltage
    Unstable memory timings (includes both main timings ie 5-5-5-15, and also tRead and tRFC.
    Only fails because of processor when vCore is waaaaaay too low!

    Blend
    This alternates between small and large data sets, and although it is a useful "last test" when run for say 24 hours after you believe you have everything dialed in and it passes Large and Small seperately, it's confusing for fault finding.
    If Blend fails it could be for any reason mentioned for small FFT and large FFT leaving you with no indication what to do to stablise the system.

    Ok I gotta hit the sack work comes early for me. G/L

    Increased the core once, all tests failed. I did a Prime95 small FTT test went on for 7 hrs no errors overnight all temperatures are normal under 60.

    This probably means vcore is not your problem. Which tests failed?
    What are your current settings?

    I used Conners setting template and uped the Vcore by one to like 1.21850V (not quite sure right now I will be home later to check). I failed the IBT, LinX, OCCT tests but running the small FTT tests I have not gotten any error so I think the problem is either the ram or the mchcore voltage like Conner's guide to Prime95 testing says. What should I try to do now?

    Let's see what your bios says first. But probably MCH Core +1 notch, VDram(unlikely if you have it set to 2.1) and or MCH Reference voltages.

    Have you checked all MCH Core options between 1.16-1.26v and then under 1.1v if thosese failed?
    Another course you can take is try use the memory as DDR-800 and if it's stable thighten the timing to something like 4-4-4-12 Those still may require changes in MCH Core. My memory isn't stable below 1.2v MCH Core with those timings at 333FSB and I only have 2x1GB.
