Forum Question: How Can I Determine Which Non-Apple RAM Is Compatible With My I-Mac 24?

I have an I-Mac 24 purchased in 2007 and I am running LION 10.7.3 OS. My I-Mac has two memory slots. I had 2 ea. 1 GB memory modules, but one “died”. Can I increase the RAM with 2 ea. 4GB memory modules? If so, how do I know I am ordering a “good” non-Mac replacement? Where is a reputable company to order from?
Current Memory Module is as follows:
Size: 1 GB
Type: DDR2 SDRAM
Speed: 667 MHz
Status: OK
Manufacturer: 0x2CFFFFFFFFFFFFFF
Part Number: 0x3136485446313238363448592D3636374433
Thank You, Rusch

    So with Lion it is easier than ever before. Go to the Apple Menu, About This Mac and then click on More Information. Then click on Memory. It will tell you what you currently have. You need to use the exact same type of memory. So as you already saw, you need DDR2 SDRAM, 667 MHz.
    So now it is a matter of going to Apple’s site and looking up the tech specs for your Mac. That will list what the maximum amount of memory each slot can take. See http://macmost.com/looking-up-apple-tech-specs.html for a how-to video.
    For instance, the “early 2009 iMac” lists “2GB (two 1GB SO-DIMMs) or 4GB (two 2GB SO-DIMMs) of 1066MHz DDR3 SDRAM; two SO-DIMM slots support up to 8GB.” But a “mid 2007 iMac” supports “1GB (one SO-DIMM) 667MHz DDR2 SDRAM (PC2-5300), supports up to 4GB.” So make sure you look yourself and find the exact model.
    Another option is to go to memory sale sites like Crucial.com or The Chip Merchant and they often have a series of forms where they can help you find your memory and how much your Mac can take. See: http://macmost.com/upgrading-the-memory-on-your-mac.html

    I upgraded my 2007 IMAc 24″ , from 2 gig to 4 gig thru Crucial.com , there they will want to scan your system to determin the type of memory your machine will accept . It’s that simple . Also It’s so much cheaper .
