Capacity and configuration

This kit provides 6GB of DDR2 memory in a matched pair of one 4GB module and one 2GB module. Both sticks are 200-pin SODIMM format running at 667MHz with CL5 timing and 1.8V operation. The unbuffered, non-ECC design is built for notebook slots that accept PC2-5300 memory.

Compatibility guarantee

Computer Memory Solutions tests each kit against the Apple MacBook "Core 2 Duo" 2.1 13" (White-08) MB402LL/A so the modules install and post without further configuration. The two-stick package fills both available sockets and reaches the system's 6GB maximum. A limited lifetime warranty covers exchange when purchased directly from the manufacturer.

Ideal for legacy MacBook owners

Owners of the Early 2008 MacBook4,1 A1181 model who need the full 6GB ceiling will find this kit a direct fit. Builders working on any other platform, including later DDR3 MacBooks or Windows laptops requiring 204-pin DDR3 SODIMMs, should look elsewhere because the pin count, voltage and signalling are not compatible.

Questions about this item

Will the 200-pin DDR2 SODIMM sticks need replacement after a certain period?

The modules carry a limited lifetime warranty when purchased directly from Computer Memory Solutions, indicating no scheduled replacement interval.

What limit appears first when the MacBook runs the 6 GB kit at 667 MHz continuously?

The platform caps total memory at 6 GB across its two sockets, so capacity is the hard ceiling once both slots are filled.

How much heat and power do the 1.8 V unbuffered modules produce during all-day use?

Operating at 1.8 V without a heat spreader, the DDR2 SODIMMs draw modest power and run cool enough for the MacBook's standard cooling.
