From this prompt, the key pieces of information to look at are:

Location: DIMM0

Size: 1024MB

Form Factor: SODIMM

Type: DDR2

Speed: 667MHz

The prompt tells you that you have a SODIMM module with a frequency of *667*MHz occupying the first slot in your motherboard. Since the speed is 667MHz, that likely coincides with the maximum support memory clock frequency for your motherboard.

The # of pins in a DDR2 SODIMM module is 200. For questions like this, I always consult with Google. All you have to do is plug in the relevant information (i.e type, form factor).

Note: check how many SODIMM slots are available, and the maximum memory supported by your OS, and motherboard BEFORE you purchase.

Tip: If you're using a 32-bit flavour of *nix, you're going to be limited to 4GB of RAM.
