I have the DP45SG with 8GB of Cosair memory, Q9550 Processor. The Probelm is that after a reset the bios loops around and around and never posts, therefore the OS won't boot. These are the things I have done:
1. RMA the board and had the same issue after the bios flash with the new board
2. Flash the new board and get the same issue.
3. I have to wait several hours to get it to boot.
I have followed Intels instructions for flashing the bios and clearing the CMOS.
