Looks to be 4GB in XP Pro, but here is a link to a MS page that may explain it better. http://www.microsoft.com/whdc/system/platform/server/PAE/PAEmem.mspx

You have 2 DIMM slots in that to achieve 2GB of RAM. Have you looked to see what PC3200 1GB DIMMs cost? 1GB is more than enough for most people using XP. If you are doing server work or RAM previews in AE then go for those big 1GB sticks. You will need to get identical sticks to run 800 FSB on that board. Get a pair of Mushkin, that stuff rocks!

There was a problem years ago with a thing called "cacheable RAM." Due to the nature of operating systems, an actual slowdown would occur if too much RAM was installed. I have not looked into this for quite some time. Type "cacheable RAM" into google...

There still are some problems if you use too much. Mostly it's a problem that your system can't address all that memory at once so there is a bit of a slowdown when using more than you actually utilize.

I have noticed that there isn't any noticeable increase in performance above 512 MB RAM. I've had up to 1GB and it doesn't run any faster than 512 MB.

The biggest 'memory-hog' on my computer is Adobe After Effects and the only program I notice a difference in. In that program you have an option to view your project using 'RAM Preview' (real-time preview). Having 1 GB of ram gives me about 3 seconds more 'RAM preview'. But that is the only difference I have noticed.
