    dfi ultra d cmos checksum error?

    ever since clearing my cmos and updating my bios i get this all the time and cant seem to shift it.

    9 times out of ten i cant boot into windows if i change anything in the bios it wont have it and just reboots and when i clear the cmos i get the error or a bsod.

    ive tried the latest bios`s but with no luck still the checksum error each time.

    is it time to rma my board only had it for 3 weeks.

    thanks.

    I'm on my second SLI-D board and this is what was happening to me. In the end each time i booted it just said Bios checksum error and i couldn't enter the bios or boot windows. I rma'd and got a new one.

    i can enter the bios but it wont update it after i change any settings it just goes into a infinate boot cycle then wont boot at all.

    only time i can get it into windows if i clear the cmos then i get the checksum error itll go into windows but next time i boot it wont and just restarts over and over.

    think i`ll try and rma it as ive only had it for 3 weeks.

    some may disagree with me and thats fine. Once you start getting that error it's the beginning of the end for these boards. RMA while you still can is my advice.
