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 :) Doug. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
