Is it worth going from 2gb to 3gb memory? For those who have done this, is there much difference? I see the 2gb modual is pretty cheap so thought I would ask. I have the 1st generation 24 inch iMac. tnks

The answer to this question is always the same: you can never have too much memory. Get as much as you can afford, and then later, you'll still want more. With a modern OS like OS X, the more memory you have, the better the performance in all areas because there's no need to touch the hard drive.

I just upgraded my aluminum 20" iMac to 4GB from 2GB. There is a very distinct improvement in app loading time, and in a lot of things it's "snappier™®". As Steve says, it's not possible to have "too much RAM". Go for it!

Wish I could bump it up to 4 gb but since I have a 1st generation iMac, my max is 3gb. Wasn't sure if I would get a performance hit by not using matched pairs. Was looking at the speed test chart on OWC web site and from what I have seen, there is a little bump up in performance. Anyone put 4gb in a 1st generation iMac even though only 3gb will be recognized?

I repeatedly have read about matched RAM here on MacNN. From what I have heard, it's completely insignificant with iMacs. So don't worry. Max out your iMac with 3Gb. It will work great.

Oh, it's possible. If you have an iMac, and three 2GB RAM modules. "Damn", you can say,"I've got too much RAM. Can't slosh it all in."

I'm still running my 24-inch imac (aluminum) with a measly 1 GB. I've had more RAM since about two days after I had the mac itself, and there are times it is SO SLOW!!! I was just thinking today is the day to finally unplug everything and put it in.
Glenn -- how long did it take?

After you find a screwdriver that fits, the process is very quick and easy. I removed two 1GB sticks and installed two 2GB sticks in about 5 minutes. There is a video somewhere on this website that I followed.

Less than 10 minutes, including finding a nice fluffy towel to put down on the table for a screen cushion. I highly recommend using an anti-static wrist cuff if you have one (or getting one if you don't-they're dirt cheap) just to be on the safe side. Changing out the RAM in my iMac was both easier and quicker than changing RAM on my MBP; no problem with "am I pushing too hard or not hard enough" or any of that stuff. It pops out and pops right back in. The two things that were not perfect were finding a screwdriver that fit the screw properly and getting the little pull tab for one of the SO-DIMMs to go back where it belonged when I had the new piece in.

I had the impression it was different to put RAM into the G5 iMac. There you had to kind of put it in at an angle. Pushing it in completely parallel in a G5 didn't make it snap so well.
With the new machines, you have to really push it in completely parallel, or it'll get stuck.

The aluminum iMacs use a different socket-a superior one from the user's perspective. The G5s had basically the same sort of socket as in MacBook Pros, which is a pain to use, even if it is very secure.
