the problem started about a year ago when I installed a second pair of 1gb memory dimms (total of 4x1gb).
everything was fine and dandy in windows xp x64 but when I tried to install windows 7 x64 I got a BSOD with the statement "ACPI non compliant".
so after a lot of adjusting things I figured out the memory was the problem. so I installed windows with only 3x1GB installed.
last week I decided I needed to update my pc and I thougt the problem was having 4 dimms installed, since 3 dimms worked just fine.
so I bought 4x2gb evo one geil dimms, and installed only three.
result: BSOD on startup(just when the windows loading logo appears). removed another memory unit resulting in 2x2gb and got the same problem.
tried it with only one unit installed= no problems at all!
so I can state the problem is in having 4gb or more installed. before anyone askes, I checked swapping the memory units and the problem is not in the dimms or the slots. windows 7 just doesn't allow me installing 4gb or more of memory.
I checked the problem all over the internet and the problem is around since the release of vista and probably has something to do with the combination between the MOBO and win7.
hope somebody can help me with this problem, running on 3gb off memory when I got a fresh quad channeld 8gb lying around seems like a waste
2x4=8 geil evo one 800mhz 4-4-4-12
1x4=4 corsair XMS2 8000mhz 5-5-5-18
asus M2N32-SLI (supports up to 8gb off memory)
