Need help with adding Ram to old computer

Hi- I have an old HP desktop, and it is rather inefficient due to having only 1 GB ram. It says I can install 4 X 1Gb (it currently has 2 X 512mb). However, I cannot find the exact ram anywhere-due to old age i guess. Anyway-can someone tell me what I can use on this computer to speed it up?
The specs now are: PC2-3200 DDR2 SDRAM

I am presuming the "3200" speed could be upgraded, but I am unsure...HELP!

That's not enough detail.

Since it is an HP some models demanded what is called LOW DENSITY RAM. Not to explain what that is, you can avoid all the trouble by going to and putting in the make and model number there.

BEWARE GOING PAST 2GB. Most of these machines can with 32 bit Windows and consumers complain when 4GB reports from 2.25GB to about 3.5GB. Even worse, apps in this version can only use 2.0GB (each app.)

still confused...

thanks for the info. My computer is the HP Media Center model m1170n running Windows XP(3). Does that explain anything any better? I see the ram cards on the Crucial site, but they seem kind of expensive. I was hoping maybe I could find something on Amazon, etc. Also, is it possible to change the "speed" of the cards? I know when I updated the ram cards on my laptop there was a difference in the "clock speed" I think it was called, yet the ones I purchased were what was recommended and seem to work great. Obviously I am a novice in this area-sorry to be so uneducated!

Armed with the Mfg name, series and model #... I found

RAM at this link....

Lots of could add 2@512 to the existing RAM for a total of 2GB or 2 @ 1GB to the existing RAM for a total of 3GB. Best to add RAM for your system in matched pairs to give best performance and compatibility. Unfortunately DDR is way more expensive than DDR2 or DDR3.

Let us know how it goes.

Looking at the HP website it says your model of PC uses PC3200 DDR SDRAM DIMMs.
Looking at ebay. com, there is a auction for two 512mb dimms for less than $20 shipped, and it says it's HP memory. Plus you can return it if it doesn't work.
ebay item number:300555832547
