To add to this question, does anyone know the EXACT brand of memory used in the iMac? I have a 20" model on its way to me right now with 512Mb aboard and would like to add an adition 512Mb. I'm a big fan of matched pairs when possible.

my 20" iMac came with Hynix memory and my friends came with
Samsung. Apple also uses Micron memory. Removing the rear cover
to change memory is very simple and involves loosening only 3 screws.

Is any brand of SDRAM OK for use in an iMac?

as with all Macs you should only use quality RAM, you are asking
for problems using the cheap generic stuff.

i bought samsung memory to upgrade my iMac from macsolutions.com
they have good prices and a good reputation.

Crucial is as good a place as any - with a guarantee that it will work (unless faulty).

Just go the new iMac G5, and for those in the UK, I bought a stick of PNY DDR 400 and it worked first time. However, the PNY that I bought for the eMac (which was standard SDRAM) worked, but only half of it was recognised.

I like http://www.newegg.com for buying anything on the internet, their prices are usually the best and their service and shipping is great. Their return policy is also very good.

Don't buy "cheap" or off brand stuff. I use Corsair myself in both my Power Mac G5 and iMac G5 and it works great.

As for getting into the iMac G5, couldn't be easier. Put a soft towel down and lay the iMac monitor down on it. There are only a few screws in the back and the whole back comes off and the slots are right there. Very easy to get at and change.

I read an article (I'll see if I can find it) that said to make sure your RAM matches in the iMacs or else it won't use dual channel mode. Dual channel was shown to get about 5-7% performance boost on the iMac i saw tested.

Ideally you wouldn't just get the same brand, but make sure it was from the same batch.

The 512 in my iMac and the 512 upgrade I bought from apple were both Micron.

hi

i disagree with some of the earlier posts ram is ram
as long as its the same spec generic stuff works just fine
in a mac. lets face it your mac is not gonna explode cos you fitted
a third party brand of memory. if a pee cee can use it then a mac can.

though i would always use matched pairs.

as for fitting its a piece of cake on the imac g5 ( if i can do it
anybody can)

two phillips screws ,slide off back panel, slot memory on board
- no problemo

regards

I guess you are not aware of the problems people had with certain RAM chips, when Apple made a change to several of their systems. Apple products are very picky when it comes to RAM.

I got a imac G5 a week ago, installed a 1024 MB chip from the cheepist deal that i could find on the net. Did a full system check and everything was sweet, worked great for a few days and then the computer went completely dead, did nothing at all. As the computer was only a week old I didn't test it myself to see what was wrong and just took it back to the apple dealer (where it has been for a week now). My apple dealer blamed it on the ram that i had installed, is this possible? the ram was made by 'whitelake'.

I doubt that the memory would have done anything, but they are certainly going to blame anything on you if you tell them you have done anything at all inside the computer.

If the latency on the ram was slightly high it can throw out the clock cycle, causing your mac to hang but otherwise when u take it out it should be fine. I doubt they would blame it on you because of that, apple service has always been very good (IMHO)..., also there is a chance that it could have fryed your northbridge as I have never heard of whitelake ram and it might be dodgy...

the northbridge is the bit that connects the cpu, ram, and graphics card...

Is the northbridge part of the midplane(motherboard) as thats what he said needed replacing?
http://www.white-lake.com is the companys website.
