Maximum Memory: The original iMac running DDR2-667Mhz memory has a system maximum of 2GB to 6GB, depending on model. The original Intel Core Duo (Model ID 4,1 and 4,1) has a 2GB max. The 1.83Ghz Core 2 Duo also has a 2GB maximum, all other early models (Model ID 5,1 and 6,1) all have a 4GB max, and the later versions, (Model ID 7,1) have a 6GB max.

Non-Stacked IC's: Ramjet uses a Non-stacked module for the 4GB DDR2-667 module for the iMac. The cheaper stacked IC variety of 4GB SO-DIMM draws more power, which increases heat and can cause increased errors. Ramjet ONLY uses premium non-stacked chips.

OSX Lion: The new OSX Lion requires a minimum of 2GB, and for optimal performance Apple recommends 4GB minimum. For graphic/audio/video work, or if you are running a virtual machine (Parallels or VMware), then 6GB is appropriate.

Trade-In Rebate: Your Apple original memory can be returned to Ramjet for a trade-in rebate. Please check our Rebate Page for details.

Trade-In Rebate!
Up to $15 for your old DDR3 Memory!

Motherboard RAM: 0mb
Sockets: 2 or 4
RAM Type: DDR3-1333Mhz SO-DIMMs

Overview: The latest model (ID 11,2 +) iMac Intel runs DDR3-1333 memory.
What type of RAM do you need? more information


Maximum Memory: The DDR3-1333 based iMac Intel can use up to 8GB in each of four slots slot for a system maximum of 32GB. The 2-slot versions can use two 8GB SO-DIMMs for a system maximum of 16GB.

12GB Limitation: Many DDR3-1333 4GB and 8GB modules on the market do not meet the Apple spec, and limit you to 12GB maximum. However, using Ramjet 4GB or 8GB SO-DIMMs, you can upgrade to the full 16GB to 32GB system maximum.

Non-Stacked IC's: Ramjet uses a Non-stacked module for the 4GB and 8GB DDR3-1333 module for the iMac. The cheaper stacked IC variety of 4GB SO-DIMM draws more power, which increases heat and can cause increased errors. Ramjet ONLY uses premium non-stacked chips.
