I bought a new alum 20" iMac back in January and it had only 1 gig of ram and I would like to add another 2 gigs in the empty slot. I checked the crucial website and this is the ram suggested:

Part #: CT715173 DDR2 PC2-5300 CL=5 Unbuffered NON-ECC DDR2-667 1.8V 256Meg x 64 more details


Is this the correct ram for my 2.4 iMac? I am a new switcher to the Mac.
Thanks for a reply.

The specs for your iMac. Looks like you have the right one.

Supports 667 MHz PC2-5300 DDR2 SDRAM.

Thanks for these two replies, but then in the first link that Soulwar gave me it said this:


"Internally, some "Aluminum Core 2 Duo" models have faster processors than their predecessors, but all have a faster "Santa Rosa" motherboard design with an 800 MHz frontside bus (up from 667 MHz), additional RAM capacity, and both a Firewire "400" port and Firewire "800" port"

See where it mentions 800MHz instead of the 667MHz though? Which one would be the right one then or it doesn't matter? Thanks

iMacs with support for 800MHz RAM were released starting in April 2008, so you don't have to worry about that. The RAM you listed above (667Mhz DDR2 SO-DIMM) is correct.

One thing I would check is to see if your iMac shipped with a single 1GB stick, or two 512MB sticks. If it shipped with two 512MBs, then the practical implication is that you would have to replace one of them with the 2GB stick, giving you 2.5GB as opposed to 3GB (if you had a single 1GB stick and added the 2GB into the empty slot).

Edit: Reading more closely, that doesn't seem to be your question, but the ultimate answer remains the same. The speed of the FSB is sometimes independent of the speed of the RAM, so a pre-April iMac may have an 800Mhz FSB, but still only supports 667Mhz RAM. The post-April iMacs actually have a 1066Mhz FSB, but only support 800Mhz RAM. Confused yet?

Does the difference in the 800MHz and the 667MHz matter?

Sorry for the double post. I wasn't sure it went thru the first time. Okay I understand now, thanks Dartholomew for clearing that up for me. Yes I have the 1 gig of ram installed now with an empty slot for the 2 gig module.
Thanks to the three of you.
