Hey guys, just curious as to when you buy your RAM from a separate website other than Apple, are you replacing the RAM that comes with the iMac as well or just buying the extra memory in addition to the RAM that is supplied. In other words, if you want 4GB, do you buy 4GB, or do you keep the 1GB w/ the iMac and just buy 3 additional GB. Sorry if this is confusing, but I heard that it is best to have all RAM matching so I was curious as to what I should do. One more thing, is this a good site to order from http://eshop.macsales.com/MyOWC/Upgrades.cfm?model=274&type=Memory&TI=0819&shoupgrds=Show+Upgrades ? Thanks in advance!

The answer varies from computer to computer, but in the iMac's case, there are only two memory slots. Each one can accept a 512MB, 1GB, or 2GB module. So, the only way to get to 4GB is to buy 2x2GB modules and replace the existing module(s) with them. Does that make sense?

in the CoreDuo and Core2Duo Macs you have 2 sockets, so if you want 4 Gb you have to remove the Apple RAM entirely and purchase 2 x 2 Gb.

Different Mac models come with different stock configurations: in the recent past Apple has installed 2 x 256, 2 x 512, 2 x 1 Gb, 1 x 1Gb depending on the model.

You can check the specifications at Apple.com, or under System Profiler on your own Mac.

Yes that's exactly what I was looking for! Thanks! Also, I'm not slow or anything, but I never physically put RAM in a computer, is it a difficult thing to do? Although I am guessing that it is not. And why the hell does Apple charge so much for memory?!?

Any recommended sites for me to buy from? Thanks again!

It's generally not too hard. Follow the directions, take your time and do it calmly, and make sure particularly to follow the directions to ground yourself.

And Apple charges so much because they can. ;)

As for places to buy from... there is a history that some Macs are picky about memory. In the US, people frequently recommend Crucial. Dealram also identifies memory that was specifically cited as supporting the iMac (they may not have a page for this iMac yet), and so in that case, at the very least, if you have trouble, you have a fallback.
