MacBook 13" White-08 memory kit

This 4 GB kit contains two 2 GB DDR2 667 MHz SODIMM modules built for the Apple MacBook Core 2 Duo 2.1 13-inch White model from 2008 (MB402LL/A). It targets owners of that specific notebook who want to reach the system’s 6 GB ceiling using both available slots.

Lifetime warranty and guaranteed fit

Computer Memory Solutions backs the kit with a limited lifetime warranty when purchased directly and guarantees compatibility with the listed MacBook model. The package supplies two unbuffered, non-ECC sticks using major-brand chips so the notebook recognises the memory without configuration changes.

4 GB across two slots with 6 GB headroom

Each slot accepts a 2 GB module, giving 4 GB total from this kit while leaving room for a larger 4 GB stick in one slot to reach the 6 GB maximum supported by the MacBook4,1 (A1181). The DDR2 667 specification matches the platform’s native speed, so the memory runs at its rated frequency without downclocking.

Questions about this item

Will the 200-pin DDR2 SODIMM slots on the MacBook 13" White-08 need any future maintenance or replacement?

The memory modules themselves are solid-state with no moving parts and require no maintenance; the MacBook's two SODIMM sockets are fixed on the logic board and are not user-replaceable components.

What limit appears first when the 667 MHz DDR2 kit runs at full load for extended periods?

The 4 GB total capacity (2 × 2 GB) is the hard ceiling — the Early 2008 MacBook4,1 only supports two slots and a 6 GB maximum, so sustained workloads will hit the memory-size limit before thermal or timing constraints.

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

Each stick draws 1.8 V at standard DDR2-5300 speeds with no heat spreader; power draw is low and passive cooling inside the MacBook chassis is sufficient for continuous use.
