    Win7 x64 only sees 3 gigs of ram!

    I'm using the 64bit version of windows 7 build 7100, and it only sees 4 gigs of ram, but only 3 is usable. I thought this was only an issue with 32 bit OS.
    i got an
    -Asus p5b-E motherboard
    -intel 6600 dual core
    -2 gigs of OCZ, Ram
    -2 gigs Crucial, Ram
    -Radeon 1950XT

    Any ideas as to why it cant access the other 1 gig? i will upload screen shots later, but im at work right now.

    What test did you run to determine it was only using 3GB?
    New gold bowtie with trunk
    release in the glovebox.
    Pinstriping around bowtie is next.

    I fixed the issue. My BIOS required me to turn on the 'memory remap feature' and now the post screen and windows see the full four GIGS of RAM
