3GB of RAM showing up as 2GB

3GB of RAM showing up as 2GB Last year I built a Core i7 920 system based on the ASUS P6T Deluxe motherboard. I have 3x1GB of DDR3 (triple-channel configuration), but only 2GB is being reported by: Windows XP, CPU-Z, the BIOS. Is this a hardware problem, or is the third gigabyte of RAM being reserved by the system for video card-related stuff? The video card has 512MB of RAM.

"If the BIOS is reporting 2Gb, then it's a hardware or BIOS problem, nothing to do with XP.

First thing I'd do is try the RAM two sticks at a time to see whether they're all good. Second thing would be checking if a BIOS upgrade is available."

I have used a XP Machine (32 bit) with 4 GB so i know that it supoprts upto 4 GB. since you are saying that BIOS is also reporting it as 2 GB , this should be a hardware problem, you probably need to test the slots or do some switching of the RAM modules to identify the faulty one.
