XP Pro can only access 2GB memory per application. If running 2 and 3 apps at same time, would having 4GB memory be useful? If using 4GB memory, is it better to buy 2-2GB sticks or 4-1GB sticks?
How do I match Memory to CPU, by the Bandwidth or FSB or other spec? What spec is most important? Case in point is matching or optimizing RAM with a E6850 and a Q6600 processor, P5K motherboard and Win XP Pro 32.
