Compatible Apple Mac models

This kit supplies two 200-pin DDR2 SODIMM modules rated at 667 MHz PC2-5300 for select Apple MacBook Pro, MacBook and iMac systems released in 2007, 2008 and 2009. It targets owners of those machines who want to reach the 4 GB maximum supported by the platform.

Upgrade from factory 2 GB

Most listed models shipped with two 1 GB modules or a single 2 GB stick, leaving one slot empty or both slots underfilled. Replacing the original memory with this matched pair restores dual-channel operation and eliminates the swapping that slows everyday tasks on the older architecture.

DDR2 platform ceiling

The DDR2 667 interface and the Intel chipsets in these Macs cap usable memory at 4 GB regardless of module density. Builders who need more capacity or modern memory standards must move to a later platform because the socket and controller cannot address anything beyond this kit.

Questions about this item

Does the 200-pin SODIMM form factor fit the memory slots in a Mid 2007 iMac?

Yes, the 200-pin SODIMM modules are the correct form factor for the iMac (20-inch, Mid 2007) and iMac (24-inch, Mid 2007) listed in the compatibility data.

What is the correct way to seat both 2GB modules in a MacBook Pro 15-inch Mid 2007?

Insert each module at an angle into the SODIMM slot until the gold contacts are hidden, then press down firmly until the side clips click into place on both sides.

Will the DDR2 667MHz chips require any firmware updates or replacement over time?

No firmware updates are needed for the memory itself; the modules are validated for the listed Apple systems and carry a lifetime warranty from A-Tech.
