My ubuntu 64-bit 11.10 installed box has 6GB RAM but Ubuntu only uses 4.1GB.
I have read various things about the 4GB limit etc, but all those talk about using less than 4GB.
What could be causing this?
- Asus P5Q Pro
- Intel Core 2 Quad Q6600 @ 2.40GHz x4
- GeForce 9600GT (1024MB) Card not integrated
- 3x 2GB DDR2 RAM Modules - PC-6400
