    I have an 8gpnxp-duo with 2 corsair DDR2-PC5400 Modules(2X512Mb-matched
    In the manual Gigabyte discribes how to set the memory frequency to 3 times
    host clock, but in my bios (F5) I only see 1.66, 2.00 2.66 and AUTO.
    When set to AUTO the frequency is 2.66 x hostclock(200Mhz) and not 3.00
    The memory SPD reads 333Mhz tiomings 4-4-4-12.
    So the memory supports 666Mhz, but I can't even get it to 600Mhz while the
    Does anyone know how too solve this problem?
    The Gigabyte support site tells me that they don't support overclocking!

    Only a new bios can help u or try EasyTune5 - maybe it helps?

    Thanks Steve,

    From the support site Gigabyte gave me a link where I could download a
    modified bios, but I can't discover any change in the modified F5 bios and
    the normal one. It is still not possible to set memory frequency to 3 times
    host clock.
    When I set FSB to 225Mhz, the processor (a Pentium 3,4 Ghz model 550) runs
    at 3,8 Ghz and memory runs at 600Mhz; I have to set memory frequency to
    When I set memory frequency to AUTO and FSB to 225Mhz the memory frequency
    drops to 2.00 times hostclock (memory then runs at 450Mhz).
    So the motherboard will overclock great, but at FSB 225Mhz the CPU heats up
    and also system temp.
    I would like to run the FSB at 200Mhz and Memory at 3 times 200Mhz.
    While the memory supports 666Mhz, I still have room to use the C.I.A from
    Have to say that the support site answers my questions every time, but the
    answers didn't solve the problem so far.

    Well, what's a support answer(s) worth when it does not help/ fix a thing? -
    such support is pretty useless. We both have to wait for a bios update that
    may come or not. So far we both are stuck with brand new but flawed
    hardware. I am a bit appalled about the apparent decline in gigabyte's mobo
    quality. Does Gigabyte care at the end of the day? - we'll find out!
