8 GB DDR2 800 MHz SODIMM kit for MacBook Mid 2009

This 8 GB kit contains two 4 GB unbuffered non-ECC SODIMM modules that run at DDR2 800 MHz (PC2-6400) and 1.80 V. It is built to the 200-pin SO-DIMM form factor and uses major-brand chips qualified for Apple Mac systems. The kit targets owners of the 13-inch MacBook (Mid 2009) identified by model ID MacBook5,2 and order number MC240LL/A.

Suits MacBook Mid 2009 owners restoring

The modules match the exact DDR2 800 specification and 200-pin layout required by the MacBook5,2 platform, so installation is a direct swap. Buyers whose systems demand a different DDR generation, a higher voltage, ECC or registered memory, or a capacity beyond 8 GB cannot use this kit.

Deciding specification: DDR2 800 MHz 200-pin SO-DIMM

The memory must be DDR2 800 (PC2-6400) in a 200-pin SO-DIMM package at 1.80 V; any other speed, pin count, voltage or DDR generation will not fit or function in the MacBook (Mid 2009). Verify the model ID MacBook5,2 before ordering.

Questions about this item

Will the DDR2 800MHz speed limit bandwidth on a MacBook5,2 running all day?

The modules run at 800 MHz PC2-6400, which is the native speed the MacBook5,2 memory controller supports, so sustained use stays at that ceiling.

How much heat or noise do the 1.80V unbuffered SODIMMs add during continuous operation?

They operate at 1.80 V without a heat spreader and draw only the power the DDR2 slot supplies, adding negligible heat and zero audible noise.

Does my MacBook5,2 need a specific firmware version before installing these 2Rx8 modules?

The kit is validated for MacBook5,2 (A1181 EMC 2330) and MC240LL/A order numbers; no extra firmware step is required beyond the standard Apple EFI.
