I have been running this motherboard for a long time with 4MB (2x2 Corsair CM2X2048-6400C5) with no issues at all.

I am trying to add two more identical modules for 8MB, but it will not boot into the OS.

I am running Windows 7 64 Bit. I have tried setting the Memory Remapping on, no help.

When I put in all 4 modules, at boot I get the Windows Loading Files screen, and it asks to run repair, which does nothing.

Turn off, go back to two modules, works fine. I have tried combinations of two modules in all slots, using both the two original and the two new ones, all work, so the modules and slots are all good.

Any suggestions?

Are you using 800MHZ DDR2? I used to have a similar Asus MB (P5N-E SLI) that was really fussy about memory if I populated all 4 slots with the fastest memory it would accept. I finally had to dial back the memory in BIOS to 667MHZ to make the board happy. Have you tried that?
