I just upgraded to 4GB Ram. Just added 2 of the same chips I already had. I am currently running XP Pro and it shows 3.67GB Total in Task Manager and 3.5GB in Computer Properties. BIOS shows 4096 and so does CPU-Z. Thats more than I thought I would get on XP Pro 32bit. Will upgrade to Vista 64bit soon. I have noticed\felt better performance in Unreal Tournament 3. I got 2*1GB Patriot PC2-6400 kit at Frys for $59.00. Very Fast!!
