P5B wifi deluxe RAM max only 3GB???

post #1 of 6
Thread Starter 
It can recognize max 3072mb while I install 4GB. I have 4x1GB Crucial balistix PC8000, 2x1GB Crucial balistix PC6400, 2x1GB G.skill (black heatsink). Whatever config, It MAX out 3072mb. Anyone experience with this?
Thanks.
PS: my Abit quadGT just doing fine with 4x1GB RAM!!!!

I assume you are using a 32-bit OS. 32-bit OS's only support 3 GB max( something around 3082Gb). The only way to utilize 4 gigs or ram is to use a 64-bit OS like XP Pro 64-bit or Vista.
