    Keep DMI Data is shown in the Qflash options at the top, use PgUp/PgDn keys to enable/disable.

    If your Qflash version does not have it then just clear the CMOS after you flash

    I would use the F6, it's the latest and it was posted here by Stasio

    Update: flashed to f6 using Qflash and disabled keep DMI data.
    Reinstalled windows, but after installing the chipset driver and rebooting, the computer locked with the flashing colors on the screen. :(

    Did you again reboot after that?

    Did you start by loading optimized after the flash, then set your ram settings and voltages, ect?

    I loaded optimized and increased the Ram voltage to 1.66V, but didn't adjust the QPI. I'll try uping that to 1.21 and see if it makes a diff.

    Any other BIOS setting I should adjust? I am using 2 x 2Gb RAM

    QPI/Vtt Voltage 1.050V [1.21.V]

    CPU PLL 1.800 [Auto]

    Ya, go ahead and try QPI/Vtt 1.2-1.3

    PCH maybe a notch or so, but usually not needed

    The systems seems a bit more stable. I can get into windows now, but it crashes when I try to install any more drivers.

    Update: I increased the PCH one tic and so far I have been able to update all drivers. cross my fingers...

    nope, crashed during windows update.

    my tRFC is set to 60 [Auto]
    I have read before to try 80 and 88. Could this make any difference?

    What you see on the left of the BIOS is not what auto is using, you would need to use CPU-z, memset, cpu tweaker, or everest to see actual tRFC in used if you leave auto set.

    4GB at 1333 may need 62-72, try 72 out and see if it helps, if it does then you can try to lower until things fail again then raise it back up

    Nope still crashes.

    I have noticed that if I am using one stick of ram or if I turn the voltage down to 1.5V, the system is more stable. It also seems to crash under high load circumstances. Is it possible it is the PSU?
    ...as you can tell, I am getting desperate.

    It very well could be, I have seen a few issues with that type but on P55/X58, of course that doesn't mean it wouldn't happen on this chipset though.

    Can you borrow another one to test with to see? How about Ram, can you borrow or do you have another stick, different brand?

    Are you starting from Optimized defaults, not fail safe?
