4GB DDR2-1066 Installed... Win7x64 Not Booting
I have four identical 1GB sticks of G.Skill PC2-8500 memory, and I cannot seem to get Windows 7 to boot with all of them installed. I am using a ASUS Rampage Formula board in which I have successfully used 4GB of PC2-6400 memory in the past. I've done a BIOS update to the latest version and still Windows will not boot. I know the RAM sticks are good and I can use any of them in a 2 to 3GB configuration, and load Windows fine, but once 4GB installed it will hang at the loading screen and throw a quick BSOD (much to quick to read any info); then just restart.
This is a 64-bit OS so I have no idea why this isn't working, but it's obviously a Windows side issue. The hardware is good and no BIOS settings affect the hang or crash. Safe Mode does not work with 4GB installed either and I cannot seem to set any maximum memory settings using MSCONFIG. Windows also states that only 2.00GB is usable which isn't right either... I installed the OS several months ago with only 2GB installed, but I figured adding another 2GB, using identical modules, would work just fine. At first the board didn't seem to like it but flashing BIOS seemed to help fix any instability.
Can anybody tell me why this isn't working; have I overlooked something simple? I've never experienced this problem before...
*EDIT*
Blue Screen info is as follows:
PFN_LIST_CORRUPT
STOP: 0x0000004E
