6gb of memory. But only 1.98gb useable?

Hi everyone.

I've just upgraded my memory from 2gb to 6gb. In the system menu it shows 6gb. With only 1.98gb useable. I thought this would have been an easy upgrade but this has stumped me.

Any help or advice would be great. Need any more information then please ask.

Thanks. Dave.

There's 2x 1gb sticks installed that work fine (Nanya pc2 6400 666)'it's an old system but still works well, its my current project, the motherboard is a HP 437795. The new sticks I bought were 2x PC2-6400 800 MHz 2gb each. I may have Miss matched them and need more Nanya?

Thank you. Dave.
