Unzip all of the files into a folder
Open the folder

When the box opens clicl on the SPD tab
Get the exact type that is in it [not neccessarily brand but type]

You will then know what you need.

Alternate approach: Simply go to a RAM vendor (e.g., Crucial) and use their memory configurator to see what RAM they suggest and have available for your system.

I went to Office Max and got 3 sticks, 1G each. I got home and noticed the stick in there was actually 2 sticks of 512 MB. Fooled me. There are 4 slots and the 2 512's were staggered, slot 1 and slot 3. My guess is 2 slots per processor? I called a guy here in my area that works on computers and builds them and he told me to put a 1G stick in slots 1 and 3, and a 512 in the slots 2 and 4. I did so and started the computer and "all systems go" I guess. Everything works and the system shows 3 G of RAM. Thanks for the help, appreciated.
Btw, the slots were:
slot 1...gray
slot 2...blue
slot 3...gray
slot 4...blue
Thanks again.

yes, some motherboards do it that way, because ddr2 stands for dual data rate, and the 2 is for dual channels. for best performance (and some motherboards require 2 at a time) you need 2 sticks, and they have to be in the correct slots. some motherboard manufacturers have them 2 and 2 (the 2 slots next to each other) and others stagger them, 1 and 3 and 2 and 4 like in your case. In all actuality, it wouldnt matter if you had the 2 1 gs in the 1 and 3 and the 512s in the 2 and 4, or vise versa, as long as the 2 of the same size and type were in the correct slots, other then one being OCD, which in the case of computer building, I think its good if the techs a bit OCD it means theyre gonna be doin a good job. :D glad it worked out for ya :D

The guy I talked to said the same as you. It didn't matter if I went 512, 1G, 512, 1G or just the opposite, 1G, 512, 1G, 512...
as long as the 2 of the same size and type were in the correct slots. Thanks.
