I'm building a machine right now based around a Pentium D 820 processor and an Intel D945Pvs motherboard. &nbsp;Right now I have 2GB of DDR2 memory on there, and I'd like to install another 2GB. &nbsp;I've heard that Win XP SP2 has a limit of 2GB though -- is that true? &nbsp;The motherboard supports up to 4GB . . .<br />
<br />
Also the 2GB I have right now is running dual channel -- do I have to buy the exact same modules to run all 4GB dual channel? &nbsp;Or is it enough to match the speed/latency?<br />
<br />
Thanks!

4GB of memory on WinXP SP2?

A desktop computer is a personal computer designed for use at a single location due to its size and power requirements, usually by one person. The most common configuration has a case that houses the power supply, motherboard, disk storage (usually one or more hard disk drives and optical disc drives); a keyboard and mouse for input; and computer monitor and printer for output. The case may be oriented horizontally and placed atop a desk or vertically and placed underneath or beside a desk.
