hiya dudes,

i want to max out my ram but dont know which one to buy. here's my spec (i got this using a program called belarc advisor)

Operating System System Model Windows XP Professional Service Pack 2 (build 2600) Enclosure Type: Desktop Processor a Main Circuit Board b 1.80 gigahertz AMD Athlon 64

Slot 'A0' has 1024 MB
Slot 'A1' has 1024 MB

i use software packages such as adobe after effects, photoshop etc so ideally i want to stick 4gb in but i dont think that will work on XP - is that true? what would be the maximum gb i could put in for that spec and what memory speed, etc?

cheers!
