My new 3.2 GHz Quad Core has 4 RAM slots with 3 filled with 2GB modules. If I want to increase to 8GBs, can I simply add a 2GB module to the empty RAM slot or do I need to add only matched pairs or sets?
If matched, what get's matched? All 4 slots, so I have to buy 4x2GB modules? Or perhaps just for slots 3 and 4 and buy only 2x2GB modules?
Thanks,

OWC sells 4 and 8GB DIMM that you can just add to what you have.
You could pull one and buy 2 x 4GB also. 8GB is not a whole lot and if you think you need more than 6GB might want to consider larger capacity DIMM

Hi Hatter,
To be clear, 3 of my 4 slots came filled each with a 2 GB module. So slot 4 is empty which I was wondering if I could buy a single 2GB module and install in slot 4. That would bring me from 6GB to 8GB.
But I wasn't sure if I could do this. Cruicial tech support states that they have never tested their RAM working in conjunction with Apple RAM, so don't have any info on whether there will be issues adding just 1 Cruicial 2GB module to my exiting 3x2GB Apple modules.
I am waiting to hear back from them whether I need to for example replace slots 3 and 4 with a matched pair of 2GB RAM modules and remove the Apple 2GB module in slot 3.
But in adddition you are saying I could install 2 x 4 GB modules in slots 3 and 4 (total 8GB), leaving Apple's 2 x 2GB modules in slots 1 and 2 (total 4GB), for a grand total of 12 GBs?
yes of course you can do the 4th 2GB!
I guess I should have included the tech note for installing RAM

I really think 12GB for now makes sense, yes. $70 for 2x4GB.
The difference between "triple" and any other mix is minimal to none in real world, with more always trumping.
Amazing how cheap RAM and hard drives are now.
Yes $70 is affordable. So the move would be then:
slot 1 - 2GB (Apple original)
slot 2 - 2GB (Apple original)
slot 3 - 4GB (Crucial)
slot 4 - 4GB (Crucial)
