    Try 3.7GHz first, 436FSB.
    It's not all memory settings. For high FSB you will probably need to tweak:
    CPU Termination,
    CPU PLL,
    CPU/MCH Reference,
    possibley CPU/MCH Clock Skew,
    and of course vcore.

    It takes time and a lot of patience. Make one change at a time so you'd know which settings it was that made change for better or worse.

    When you need advise about failed settings, post the full failed settings.

    Hi chike, thanks for you reply.

    I'm using memtest86+ only.

    I change the timmings between (5-5-5-18 & 6-6-6-18) &...

    the MCH core between (1.24-1.26 & 1.28)

    The other settings are equal.

    Regards.

    memtest86+ is not enogh. It can detect bad memory and horrible memory settings but that's about it.
    At least 6 hours of Prime95 blend are needed before you move to a higher OC, and 8+ hours if you want to save a stable OC profile. A couple of hours small FFT are recommended also.
    It will help to find the required changes along the way.

    As I said, there are other settings to deal with, it is not just MCH and memory.

    Please repost your settings in question.

    If you want higher FSB just save it in BIOS profile(F11) like it is, you can tweak it more later.
    Try FSB 436 for 3.7GHz

    Code:
    Static tRead Value.....................:8 [11] <<< set it down 9 or 8 later
    
    CPU Vcore….……….........:1.25000V....:[1.26875] << may need more
    CPU Termination…....... 1.200V*.......: [1.200V] << try 1.2 to 1.26
    CPU PLL…………………......1.500V*.......: [1.500V] << try 1.5 to 1.6
    
    MCH Core…………….....1.100V...........:[1.24v] <<< try 1.24-1.28
    Try combinations of the above settings, and timings as you tried before.
    You may also try Clock Skew if the above do not work
    Code:
    CPU Clock Skew (ps)....................: 0  <<< try 50 with MCH Clock Skew 0
    MCH Clock Skew (ps)...................: 0  <<< try 50 with CPU Clock Skew 0
