MacBook Pro 13.3" memory upgrade

This 8GB kit supplies two 4GB DDR3 SO-DIMM modules rated at 1066MHz CL7 for the Apple MacBook Pro 13.3" Intel Core 2 Duo 2.26 MC207LL/A. It is built for owners of that specific notebook who need the factory maximum of 8GB across its two slots. Builders working on any other platform cannot use this memory.

Low-voltage unbuffered operation

Each stick runs at 1.5V without ECC or registered buffering, so the memory controller sees standard DDR3 signalling and draws only the power the original design expects. The modules have no heat spreader, relying on the MacBook’s existing airflow to keep temperatures in the normal range. No extra cooling or fan changes are required.

Two matched sticks in the box

The package contains exactly two 204-pin SO-DIMMs from a major-brand chipset, giving a ready-to-install pair that fills both sockets. There is no software, driver disc or configuration utility included; the Mac recognises the memory automatically at boot. Buyers who want a single module or a different capacity must look elsewhere.

この商品に関する質問

How do I install the 204-pin DDR3 SODIMM modules in the MacBook Pro 13.3" MC207LL/A, and what step do people often get wrong?

Power off the MacBook, remove the bottom case, release the retaining clips on both slots, insert each 4GB module at an angle until the gold contacts are fully seated, then press down firmly until the clips click — the step most often missed is pressing down hard enough to engage both clips on each stick.

What maintenance or replacement will the CM512648500SODRH kit need later?

No scheduled maintenance is required; the unbuffered non-ECC DDR3 modules have no moving parts or batteries, so replacement is only necessary if a stick fails or the system is upgraded beyond the 8GB maximum supported by the MC207LL/A.

What limit appears first under sustained heavy workloads with these CL7 1066MHz modules?

The memory controller in the 2.26GHz Core 2 Duo caps usable bandwidth at the PC3-8500 rate, so the 1066MHz CL7 timing ceiling is reached before thermal or voltage limits become a factor.
