MacBook Pro 2007 memory upgrade

This 4 GB DDR2 SODIMM module is built for the Apple MacBook Pro "Core 2 Duo" 2.4 15-inch (SR) 2007 model. It uses a 200-pin SO-DIMM form factor that matches the laptop's two memory sockets. The stick is unbuffered, non-ECC and runs at 1.8 V, matching the original specification.

Single-stick kit simplifies installation

The package contains one 4 GB stick, allowing you to fill one slot while leaving the other for a 2 GB module to reach the 6 GB maximum. CL5 5-5-5 timings and DDR2 667 (PC2 5300) speed are factory set, so the Mac recognises the memory automatically without BIOS changes.

Major-brand chips on a plain green PCB

No heat spreader is fitted, keeping the module thin enough for the tight MacBook Pro chassis. The 2Rx8 rank organisation uses major-brand chipsets for stability. Limited lifetime warranty from Computer Memory Solutions covers the stick when purchased directly from them.

Questions about this item

Will the 1.8 V DDR2 SODIMM need any firmware updates or re-seating after long-term use in the 2007 MacBook Pro?

The module is a standard 200-pin DDR2 SO-DIMM with no firmware; reseating is only needed if a contact issue appears after years of thermal cycling.

What stops me from adding more than 4 GB in the single slot of this MacBook Pro?

The MacBook Pro 15-inch 2.4 GHz (2007) accepts a maximum of 6 GB total — 4 GB in one slot plus 2 GB in the other — so this 4 GB stick leaves one slot for a 2 GB module.

Does the unbuffered CL5 module run hot or draw extra power during all-day workloads?

Rated at 1.8 V with no heat spreader, it operates within normal DDR2 thermal limits for continuous use in the supported MacBook Pro.
