Try Buy.com at the following link for an example (you will want to make sure the exact type of memory you need; if you write back with your exact computer specifications, we can check for you, although most memory sellers have a way of entering your iMac into their system and they will tell you what you need). BTW: Kingston has always done well for me, but everyone has their preferences when buying memory.

Currently Being ModeratedJan 1, 2008 11:18 AM (in response to Testemonial MAC convert)Unless I'm missing something, the link you gave was to a single 3gb chip, which will NOT work with your iMac, from what I have researched.
Your iMac can take up to 2gb in each slot, but can only handle up to 3gb total. It came with each slot having 512mb in it, so these will have to be removed and sold or trashed.
You could put a 2gb chip on one side and leave a 512mb in the other for a total of 2.5gb. Many people will tell you to use only matched pairs, which has a slight benefit, but the greater benefit is from having more RAM overall!
Or, you could put 1gb on one side and 2gb on the other side for a total of 3gb. You decide.
Here is a link to a page with your iMac's specifications: http://www.everymac.com/systems/apple/imac/stats/imac-core-2-duo-2.16-20-inch-sp ecs.html
Here is another one that explains why 3gb is the maximum RAM for your system: http://www.memory-up.com/Memory/AppleiMac14834.htmliMac 17" 1.8GHz PowerPC G5, 1.5gb SDRAM, 80gb hd, Mac OS X (10.5.1)
No, the link is for a 3gig kit, with 2 gig and 1 gig chips. I want to make sure that the iMac can handle that. According to the manufacturer's website, it can. But i have read in the past that it is best to use the same size pairs in the slots which makes no sense since the imac can handle up to 3 gig and there are no 1.5 gig chipsiMAC 20", Mac OS X (10.4.7)
Currently Being ModeratedJan 1, 2008 11:41 AM (in response to Testemonial MAC convert)It looks like Buy.com is in error listing that 3GB upgrade, here is the same upgrade # from another supplier that shows the upgrade as 1x1GB and 1x2GB modules.

Currently Being ModeratedJan 1, 2008 12:14 PM (in response to Testemonial MAC convert)Yes, I googled: Corsair VSA3GSDSKIT667D2 from your Buy.com link to find other suppliers selling that upgrade kit. At the time I was more concerned that someone was trying to mislead and(or) sell us a 3GB module than the price. Most folks won't have any use for a 3GB kit in there new iMac, it already has a 1GB module. They need a 2GB module to bring there system up to 3GB or 2x2GB to bring there system up to 4GB.
By the way look down at my post to the OP, the 4GB kit from newegg is a better deal!17" iMac Intel Core Duo - 2GB Ram -, Mac OS X (10.5.1), - Maxtor 300GB FireWire - 2G Nano
*I have had great experiences with OWC* (aka MacSales.com). My last 4 Macs were all upgraded with memory from OWC.
*I would avoid Buy.com*
They have the worst reputation for service.
Don't take my word for it, just surf to http://www.resellerratings.com/store/Buy and what their customers/victims have to say.iMac (2.8GHz), iMac (2.16), MacBook (2.16), MacBook (2.0), Mac OS X (10.5.1), Brother HL-4070CDW, 3 iPods, G-Tech FW drives, OWC FW drive
Yes have a look at the tech spec's!
