Our RAM configuration isn't that simple, though. Although the board
posts just fine with 4GB, running a 32-bit windows OS doesn't quite
give you full access to the RAM. Check Windows XP and it'll report
only 3.25GB free. So is the other .75GB wasted? Not quite. It's a
complicated issue, but Microsoft argues that even if the
applications cannot use all 4GB of RAM, the OS, and even the
drivers, will, so the additional headroom does help.

Side question on this. If I had 8GB of RAM, and 32 bit XP, could I
create a 5GB RAM drive, and use it for temp and swap files while
still using the other 3GB for Windows? Wouldn't that give me, in
effect, the advantage of 8GB of RAM since I'd be paging at RAM speed?
