Overview: The Early 2009, Mid 2009, and Late 2009 iMac Intel (Model Identifier 9,1 through 11,1) runs DDR3-1066 memory.

Maximum Memory: The DDR3-1066 based iMac Intel has a system maximum of 8-16GB. The 2 slot versions (Model ID 9,1) have a 8GB max, and the 4 slot versions (Model ID 10,1 through 11,1) have a 16GB max.

Non-Stacked IC's: Ramjet uses a Non-Stacked module for the DDR3-1066 modules for the iMac. The cheaper stacked IC variety of SO-DIMM draws more power, which increases heat and can cause increased errors. Ramjet ONLY uses premium non-stacked chips.

1066 vs. 1067? The correct name for this memory is DDR3-1066. But since it runs at 1066.66Mhz, the Apple System Profiler reports it as 1067Mhz.

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