    Exclamation Strange BIOS issue with GA-X38-DQ6

    Hi All,
    I've noticed a strange behaviour with by GB Mobo.
    I have a Q6600 on this & usually run this board on 400x7=2.8Ghz but wanted to try to push this higher.
    Started with reducing the mem speed and increasing the CPU/FSB slowly. The thing I notice is that whatever I try to set it to the machine always boots at 2.13Ghz.
    Even if I load the saved profile of 2.8Ghz when it boots, it starts at 2.13.
    The only profile which works correctly is the 2.4Ghz base profile I saved when I first installed this machine a few years back.
    Now, for the really strange, even If I boot and the machine shows 2.13Ghz on the POST screen, when I enter the BIOS, it shows be 400x7 = 2.8Ghz.
    Why is the BIOS not showing the values being applied ?

    For a test, I also tried letting it boot into Mem test just to make sure that it's not just the BIOS screen showing higher that applied values - memtest shows 2133Mhz.

    Anyone hit this issue before ?

    When you enter BIOS do you get a red warning message?
    If you do have you read it?
    Try clearing CMOS, both battery out and the CLR_CMOS pins shorted for 20-30 minutes.
    Be sure to do it when the PSU is off or unplugged from the wall and discharge the capacitors by pressing the power button once after you turn the PSU off.

    I don't see any warning when entering BIOS - Should it appear on any particular screen ?
    I will try clearing CMOS - do you know if doing so will remove my saved profiles ?

    When you enter M.I.T there shouldbe red warning at the center of the screen.
    Clearing CMOS does not clear saved profiles.

    No special/new red warning on the screen. There's the usual "System voltage not optimized" message which ironic as it seems is normal when you select manual voltage control for any kind of overclock or even to set the DDR to 2.1v.

    ok, after clearing CMOS, I'm able to change frequencies now. Maybe it's time to replace the CMOS battery ?

    Won't do any harm, but I don't think that's the issue, it jus seem that sometimes the BIOS need to be cleared to function properly, no idea why.

    Maybe the BIOS just needed a kick :) I think I'll replace the battery anyway, it's old now 3+ years.
    Hey I have noticed one more strange thing - I've set the BIOS to 360FSB multiplier 6 which should yield 2160Mhz - This is reported in the POST screen and also in CPU-Z, but Windows reports "Intel(R) Core(TM)2 Quad CPU Q6600 @2.4Ghz 3.24Ghz" - Why is it reporting 3.24 ?
    I don't have much faith in windows, but I checked MemTest86 v4 & v3.5 also they both report 3240Mhz when testing.
    Is the BIOS still reporting incorrect values, which are being read by windows/memtest but CPU-Z actually measures the value hence showing the correct 2160.1Mhz ?

    Edit: Add to this I ran a benchmark on Prime95 and the results.txt file has - CPU Speed: 3239.90Mhz, 4 Cores...
    No way !!!
    On Max load HWMonitor shows 51 degrees and CPU vCore is 1.22v - There's no way this is running on 3.2Ghz ! Something is odd here.

    Seems that some software get confused and just use the max multiplier times FSB (360x9=3240).
    Isthat with Windows 7, Vista or both?

    Both - I booted into each OS. Also Memtest86 v4 &v3.5 and Prime95.
    I checked memtest 2.11 - this is showing the correct speed - Might be software after all.
