    Oh yes! You are right off course! Here is an update. I have just finished prime95 Blend Test running for 1 hour without errors. That's my best.
    I used 1.66 Ram vcore, 1.26 CPU Termination and 1.34 MCH core!!
    I am doing another run of prime to make sure and then I am gonna tru your settings! Thanks!

    MCH Core 1.34 is a bit too much, can't u\you set it lower?
    No changes made to MCH Reference?

    MCH Reference left it to auto! (I am afraid of it a little!) After I finish the second run I will lower MCH voltage to test it because you are probaly right, it is too much! At last I found a sweet spot.
    I had tried RAM Vcore this low but with higher MCH and CPU Termination voltages and wasn't stable off course!

    Usually not more than 1,26v MCH Core is needed for 4GB at your current FSB.
    There is nothing to fear of Reference voltages, just follow the instructions on how to set them in the links I have posted.

    EDIT: http://www.edgeofstability.com/artic.../gtl/gtl1.html explains the role of CPU Reference.

    Well, I tried 1344MHz: 1,26 VTT, 1,26 AND 1,30 MCH voltage with 1.66 RAM vcore and both failed in one hour. MCH reference is auto.
    I will try to get 1400MHz stable with 8-8-8-24. Any suggestions?

    Why 1400 should be good with 7-7-7-18/20.
    Can you post full settings you had in post #11?

    EDIT: and a screen capture of MemSet main window only if you can.

    I was a bit off about tRAS, you may need 21 or 22.
    Please post the settings again when you are done, failed or succeed.

    EDIT: tRFC 78 was actually right for 1400, I'd leave it on auto untill things are stable then see how low can it go.

    Ok I will lower it (tRFS) if it fail Prime95. Currently I am stable (55 minutes so far) at 7-7-7-20-76, 1400MHz 3.33D strapping. Strange thing is that on Everest Memory benchmark I 'm a little faster at 1344MHz 8-8-8-24 than 1400 7-7-7-20 WTF??!

    EDIT: My chipset is cooking at 37 C degrees!! Running Prime almost all day!
    EDIT2: Prime failed at exactly 1 Hour again.

    Higher tRFC actually, never mind if it works it works.
    We'll look into performance later when everything is stable with lower MCH Core hopefully.

    35c is cannot be considered cooking, check my signature, that's IBT temps though, Prime get "only" up to 65c or so.
    What temps are you reading, core temos or CPU temps?

    What size FFT? Blend as it's name combined of small, medium, and large FFTs.
