    Updated Sig for you.

    I have gradually raised the Vcore as high as 1.49V and I see no increase in GFlops in IBT, I always get around 19.5.

    I have also managed to set the tRD @ 7 and it is running stable.

    Very odd, I had 20.8 at 3.16GHz with 333MHz FSB, try to set threads manually to 2 and see if it's any better.

    I have set threads to 2 and still no luck. I am using V2.4 of IBT.
    I have raised the Vcore up to 1.47V as seen in CPUID HW monitor and the cores were at 70C with the CPU at 61C, and IBT failed on the 2nd test.

    Maybe more FSB needed, not sure about safe values, wait for Lsdmeasap opinion.

    Meantime, try pressing Ctrl+F1 in main BIOS screen and see if it adds GTLREF options in MIT, and what are their options if it does.

    Ctrl + F1 no longer adds anything since the newer bios updates, and there is no GTLREF option in the bios.
    At 1.33 Vcore it will clear all 5 IBT passes.
    Will wait for Lsdmesasap regarding raising the FSB voltage, thanks again Chike.

    BTW on Sandra Arithmetic performance benchmark I achieve;
    Whetstone 21.7 Gflops
    Dhrystone 27.7 Gflops

    Were there GTLREF options before?

    No I don't remember ever seeing them

    Hey Lsdmeasap, is there a maximum FSB overvoltage that I should stop at, the MB will allow me to add a max of +0.3V and currently I am at +0.1V?
    Thanks..

    +0.3 is likely not needed until 500+ FSB, and if you use it I do advise you put a fan on the NB heatsink.

    +0.1-0.2 should be all you would need, if that, under 500 FSB
