It has 2x 1GB 1Rx8 PC2 -6400U-666-12 memory dimms in it.. I want to upgrade the memory now..
My question is what should I be looking for to figure out if a particular Memory card is compatible or not to my system/existing memory.


From HP website:
Standard memory
512 MB 800 MHz DDR2 SDRAM
1 GB 800 MHz DDR2 SDRAM
2 GB 800 MHz DDR2 SDRAM
4 GB 800 MHz DDR2 SDRAM
