I have ASUS P5KC currently with 4GB RAM (two Corsair CM2X2048-6400C5 DDR2 modules) see below. I've then bought two additional modules which seem to me identical apart from the version (3.3 as opposed to 3.1). When I added to the slots 2 and 4 on the mobo, the initial start screen says 8096MB RAM and finds all other devices etc but the boot process stops is restarted a few times and finally I get the "BOOTMGR image is corrupt. The system cannot boot." I'm wondering are there any settings I could try to adjust (btw I have trouble even getting into SETUP/BIOS), e.g. speeds, voltages, etc. or are the two sets of RAM modules not compatible and I'm out of luck and should buy a set of 4. If so, would this one, for example, work - Komputerbay 8GB 4x 2GB DDR2 800MHz PC2-6300 6400 RAM Blue Heat Spreaders 8 GB Thank you
