Question about Intel Motherboard

CMOS checksum bad 0085

I have installed a ECS 945p-a v1.1 motherboard and a 3.2 gig celeron D processor, trying to build myself a computer. When I boot the computer it gives me a message saying CMOS is invalid 0085 or overclocking failed, one of the 2 messages showes up and wont let me go any further. I have replaced the batt. and it did not fix the problem.

    When i change bios settings and then hit F10 to save and exit the computer reboots back to the settings befor i changed them, back to square one.

    This worked.

    1. With just a USB keyboard, VGA monitor and power plugged, power on
    the computer and enter the BIOS when prompt (after the 'date not set'
    message). Once in, just exit and SAVE settings. I mention save because
    using the 'discard settings' caused the system to be inoperable and
    requires the CMOS to be cleared.


    2. After exiting BIOS, the pc should restart. During this period,
    unplug the keyboard. Now, watch the screen and see if the pc bypasses
    the the "CMOS checksum bad", "Over-clocking failed !!!" and the message
    to enter setup. Right after those lines, a new message along the lines
    of "NVRam...." will appear and it will proceed to boot, only to stop
    due to no bootable device. Insert a Windows cd and power off (and
    unplug) the pc and clear the CMOS.


    3. Now, power on the computer and follow the procedure in step 2 with
    the keyboard. After the "NV...." message, the pc should begin to boot
    into the Windows installation. I recommend to partition the HD to 5gb
    and quick format in NTFS to reduce time waste, since this will just be
    a temporary install. After the Windows install restarts the pc, power
    down the pc and clear the CMOS again. Turn on the PC as in step 2 and
    continue the install, with every restart acompanied by the clearing of
    the CMOS.


    4. After Windows is installed and you are able to boot into Windows,
    update the motherboard's firmware in Windows according to ECS'
    instruction. I recommend burning the bios and flashing program from
    another pc to transfer to the ECS machine. After the reflash, restart
    the computer. This time, leave the keyboard plugged. The pc should now
    boot up without error. If an error occurs, clear the CMOS and try
    again. It should be working now.


    Well, that should be most of the information there. Reading it may be
    difficult since I jumped around inputing the steps and each step isn't
    exactly a one liner command. Hopefully this helps. Maybe when the sale
    comes again, you can try this out and get it to work.

The problem might lie in the fact that the mother board and cpu cannot be handled at the speed

or it requires the jumpers to be set by so that the cpu can be clocked properly if you got a mother board spec guide follow the guide for *********** board to set up 3.2

you might also have to set the bios to the cpu speed cause if mother board doesnt do jumpers no more the setting would be in bios
hit the delete key direct are power up this will take you to bios
its not the battery

Has the motherboard got a new BIOS battery?
Check the voltage of the battery, if it is a lithium battery CR2032 then the voltage should be 3 volts, if it is less than 2.98 volts then replace the battery.
