have you used the usb flashback to put the newest bios file on the mb. does one dimm work?? if your still getting the error check the cpu for bent pins under it or a seating issue.

I not sure how to the flashback. I have never got it to boot to bios yet. I check the cpu could not see problems there.
I did try each dimm one at a time. Stile have code 55. Thanks

look at your mb serial number the last 4 number is the bios rev.
1602 is the last bios file for your mb.

what you do to use the usb flashback is download the bios file and the bios renamer under bios tools. then copy the file to a usb stick. with the power off and mb showing power good. plug the usb stick into the usb flahsback port and hold the button in for a few seconds. (uab flahback button). the button will go into a blinking mode for a few min as it reads and flashes the bios for you. when it done the usb flashback led will turn off.

Make sure you are insterting the memory modules fully - they should click on both sides of the slot. Some users don't push the EZ side of the modules down properly into the slot.

If it's not that, try one module only in each slot and see if the board will POST after you clear CMOS.
