Here's one for you hardware wizards...
I have just upgraded my memory from 2gb to 4gb by putting a pair of 1gb Crucial DDR2 modules. I already had 2x1gb Corsair DDR2 modules. Before, when checking the System Info (under XP) it showed 2gb memory. With the 4gb installed it only reports 3.12gb installed.
Could this be because I have mixed modules, the limitiations of XP, or some other suitably obscure problem?
Cheers,
Richard
