MacBook Pro Mid 2007 upgrade

This 4GB DDR2 667MHz SODIMM module is built for Apple MacBook Pro models from Mid 2007 and Early 2008. It also fits the 13-inch MacBook from Late 2007 through Early 2009 and the Mid 2007 iMac. The 200-pin unbuffered design uses major-brand chips at 1.80V.

Replaces factory 667MHz modules

It upgrades systems originally shipped with lower-capacity DDR2 667 PC2-5300 memory. The jump is worthwhile when the Mac supports a 4GB module in a single slot and the workload needs more headroom for multitasking. Machines limited to 2GB or 3GB total will not benefit.

Installs in the user-accessible slot

The SODIMM seats in the standard memory door on these Macs with no tools beyond a screwdriver. Ensure the notch aligns with the keyed socket. The most common issue is inserting a module into a machine whose firmware caps usable memory below 4GB.

Questions about this item

Will this 200-pin SODIMM fit the memory slot on my Mid 2007 iMac?

Yes, the module uses the 200-pin DDR2 SODIMM form factor required by the Mid 2007 iMac and the other listed MacBook and MacBook Pro models.

What is the correct way to seat the module so the Mac recognises the full 4 GB?

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

Does this DDR2 667 MHz stick need any periodic cleaning or replacement?

No routine maintenance is required; the memory has no moving parts and no heat spreader, so it runs for the life of the system unless a fault develops.
