I searched before posting and came up with nothing so...

I have an 24" iMac that I purchased in late 2007 (model ID 7,1) with 2 gb (1x1) of memory. I want to upgrade to either 4 or 6 gb, but I am having some difficulty finding a good site that I can buy it from (other than Apple). I've checked out OWC and saw that they have a variety of different combinations for prices from $100-200. This is my first time upgrading my memory so I am not sure what to look for. I would like to keep the cost to $200 if I choose to get 6gb, but I also want to buy the correct one that will perform best.

Can anyone point me in any direction/website and recommend a specific combination to get? I use my computer for video/photo editing and encoding, word processing, web surfing, and basically everything else...and I always have multiple applications running at the same time. I appreciate any suggestions anyone can provide

The two best places to buy memory from are either OWC or Crucial. Both are very reliable with good customer support. You may pay a bit more but you'll be assured of getting the correct memory. Also good quality memory.

Here's some info that you have to know:
iMac (Mid 2007): Memory Specifications

To sum it up, your system can support no more then 4gb of ram, and it's specs should be PC2-5300, 667 MHz DDR2 SDRAM.

As for the manufacturer, Crucial is good, but you are safe with pretty much anything that meets the criteria above.

Visit Apple iMac Memory Upgrades for 17", 20", and 24" Models equipped with Intel Core 2 Duo 1.83GHz, 2.0GHz, 2.16GHz, 2.33GHz, 2.4GHz or Core 2 Extreme 2.8GHz and choose your poison..

If you have a late 2007 model, you can go up to the 6GB, otherwise go for the 4GB (2GB x 2)..I've used OWC memory on my Mac Mini and when it comes time to upgrade my 27" iMac, I'll go with OWC memory again, cheaper than Micron, Crucial, Samsung, etc., but no real issues seen yet..

thanks for all the replies. I want to get 6gb instead of 4gb, but can my iMac support that? From what MacKeeper posted, it looks like I can only support 4gb, but is that only because that was the largest option on Apple's website when I bought it?

@gnotti211, if you follow my link to OWC..they have the 6GB available and note that it will only work with a late 2007 model..so as long as you have that (you can always call them and confirm), you should be good to go.

thanks raz0redge...i contacted OWC and they weren't much help though, probably just didn't get lucky with getting a good person on the other end. However, I searched a little more in depth here and found this site: iMac "Core 2 Extreme" 2.8 24-Inch (Al) Specs (Mid-2007 - 24", N/A, A1225, 2134, iMac7,1) @ EveryMac.com which says that my particular iMac can support up to 6gb, and even lists OWC as a place to buy it from.

Are there any drawbacks to putting 6gb in my iMac when Apple only lists 4gb as the maximum?

There isn't any actual drawback, its a simple matter of whether it will or will not work.
If your model is a later 2007 one and it supports up to 6, then 6 will do.
If it is the earlier, it should not boot up at all.
Get the exact model serial number, do a search with it or maybe even contact Apple support to clarify this, since this is crucial and has to be verified before buying any upgrades.

thank you everyone for the replies. i went ahead and ordered the 6gb...if it doesnt work out well, i'll send it back but i'm pretty sure everything will work out fine.

Pursued iMac 2007 and 2008 can be upgraded to 6GB RAM regardless of specified 4GB limit and ended up getting the following immediate reply from Justin Leskovsky at Edge Tech: Below is a link to a page that contains the 4GB and 2GB you would need to attempt the 6GB setup. We were aware of this possible upgrade, but chose to remove the 4GB+2GB kit from our site, due to how often systems cannot take the upgrade and remain stable over time. Please be aware that you have no guarantee that that attempting this update will work.

Loved their correct response in light of problem(s) with the, so called, sure thing claimed by others and am ordering their standard 4GB Kit 4GB (2X2GB) PC25300 NONECC UNBUFFERED 200PIN DDR2 today.
