Click to expand...

The ram is called PC4200, 240 Pin, 533mhz DDR2 SDRAM, and your machine can take 2.5GB max, and you will need most of that to run games on it :)

However, with 512mb on the mobo, the only way to get there is to buy (1) 2GB chip, which are fairly expensive. A 1GB chip would suffice for most other tasks, giving you 1.5GB, but games are usually ram-hogs....

Instructions for opening it should be @www.apple.com/support :)
 
Back from the thread.

I'm looking to add to the stock ram in my iMac (the same lsited above). I see a few websites That list the 2GB module in the $300 range... the 1GB is much lower at about $100.

Does 1GB help... enough? Any thoughts from someone who has upgraded?
 
a 1 Gb module (1.5 total RAM) helps certainly, over the stock 512 Mb, and is enough for most tasks. It depends what you do though. If you do pro level graphics, video or audio production, (probably gaming as well) you would benefit from the 2 Gb module (2.5 Gb total RAM).
 
There's the rub... I am doing pro level image transformations and rendering. I've always kept in the back of my mind... the time I went from 512 to 1GB in my AMD Thunderbird system and gained very little from it.. I realize that systems have changed a ton since and I don't know why I still think about it.. but I always hesitate on ram upgrades. :)

Two gigs would be the max benefit, so 2GB I must obtain... now I need the cheapest, tested source.
