Finding out exact RAM to buy

[samsalmanu]

Obviously a newbie here.. And my apologies for what may be a very silly question for most of you ..

I'm planning to get a 2GB ram module to add to the 1 GB thats already present ..

How do I find out exact specifications.. going thru System Profiler I got the following
667 MHz DDR2 SDRAM.. but wud that b 200pin or 240 pin .. how do i find that out>

Also , a related query .. Is the performance better if I have 2 1 GB sticks or is it okay to have 1 1 GB and 1 2 GB module in place ?

What Mac do you have?

200 pins are for notebooks (PPC/Intel) and the iMac/MacMini (Intel) and 240 pins are for MacPros and iMacs (PPC) if I'm not mistaken.

And maybe the Apple Store can help.

iMacs use laptop ram. Also check out Curcial or OWC, the prices are cheaper than the kingston ram you were looking at.
