Go to HERE and run the Crucial online scanner.
This will give you the exact memory configuration for your system.
You do not have to buy the memory from there, but write down the information and if you need assistance in purchasing the upgrade memory GTG can assist with suggestions also.

Maximum Memory: 1536MB
Slots: 3 (3 banks of 1)
Standard Memory: 256, 512, or 1024MB removable
USB Support: 2.x Compliant
Q: Will my system recognize the maximum upgrade?
A: Possibly
The amount of memory your Windows computer will recognize depends on two factors:
the maximum capacity your computer hardware can handle and the version of Windows your computer uses.
The most memory the 32-bit versions of Windows will see (and utilize) is only 3GB or 3.5GB, if your computure hardware can handle it. The 64-bit version of Windows can address even more memory. Find out more at http://www.crucial.c....aspx?qid=4251.
Q: What memory goes into my computer, and will a faster speed be backward-compatible?
A: DDR memory with support for DDR PC2700 speeds.
Because DDR memory is backward-compatible, you can safely upgrade your system with any of the guaranteed-compatible DDR speeds listed below, even if your manual calls for PC1600 or PC2100 speeds.
Q: How much memory can my computer handle?
A: 1536MB.
Adding the maximum amount of memory will improve performance and help extend the useful life of your system as you run increasingly demanding software applications in the future.
Q: Do I have to install matching pairs?
A: No.
No, you can install modules one at a time, and you can mix different densities of modules in your computer. But if your computer supports dual-channel memory configurations, you should install in identical pairs (preferably in kits) for optimal performance.
Q: Does my computer support dual-channel memory?
A: No.
Your system does not support dual channel.
Q: Does my computer support ECC memory?
A: No.
Your system does not support ECC. Because ECC and non-ECC modules should not be mixed within a system, install the same type of modules that are already in your system.

I have a 512 MB 2100--Can I mix speeds and add 2 2700's?

You can go to the max as the XP 32 bit version will utilize up to 3.5 gigs. Your system maxes out at 1.5 gigs.
Your memory needs to be DDR PC2700 speeds.

I'm taking it this is a desktop system correct?

Any of the memory on this list HERE will work for a desktop system.
Personal preference for me would be Crucial or Corsair.
