    Looks good to me. The only item I see that might be a little shaky is the tRAS, but if Memtest86+ runs without errors at that setting, you're golden.

    I would see if you can lower the voltages any and still be stable, that will help your system live longer. In particular you should not need to boost the PCI-E voltage at all.

    I'm lucky enough to have a Q6600 system on a P45 based board that runs 3.0GHz at stock voltages. In fact my FSB (CPU Termination) and MCH core are undervolted! But then I'm running 800MHz DDR2 and not 1066.

    Thanks mate will try your advice not sure what you mean shaky for tras that's set at 15 as labeled on the stick.
    But you do have something here system wouldn't start at first only when set at 18 more tweaking in the advanced section then let it boot i think it was Refresh to ACT Delay_________________ 52 [56]
    But i maybe wrong are you saying revert back to 18?
    Thanks

    I'd suggest the Corsair support forums for advice on your particular memory. tRAS of 15 is pretty aggressive for DDR2 @ 1066, those would have to be really good devices to work at that setting. But if it works... great!!

    Is that 2 x 2GB or 4 x 1GB? If they're 2GB sticks, from what I have seen on the OCZ support forums, your Refresh to ACT Delay is probably on the low side. They usually recommend 72 or more. Give it a try and let us know.

    Thanks again,
    I take it you suggest changing to 18 even though it's designed to run at 15?
    Also will alter the ACT delay and pci voltage.
    This is a 2x2GB set.
    Cheers

    I tend to be pretty conservative about overclocking. If there's even a hint of instability, I usually back off.

    The only way to know if tRAS=15 is stable is to test it. I usually check my memory timings by running the free memory test suite Memtest86+ overnight. If you get 0 errors, your timings are fine.

    Memtest86+ can be downloaded as a .iso file. Burn it to a CD and you can boot the test from the CD. That way your hard drive won't get corrupted if your timings aren't stable.

    I have i ran that test for 10 hours and no errors.
    Just downloaded linpack i don't have the 64bit system and it ran it on section 3rd memory but figures wern't equal they should be i think.
    Cheers

    10 hours of Memtest without errors is plenty stable in my book!

    Linpack will definitely stress your cooling more than any other test I know of. I get core temperatures 6-10C higher than prime tests. Watch your core temps!
