That was/is going to be my next upgrade. I went to the store here in
Kingston and couldn't get any pairs of DDR2-800. It was just after the
price had dropped and they couldn't get any. I'll have to try again.
Actually, I figure that while I'm at it, I'll make it a pair of 2 GB
sticks, unless of course a set of 4 is on a great sale
