Apple MacBook Pro DDR2 SODIMM kit

This 4 GB kit contains two 2 GB DDR2-667 SO-DIMMs built to PC2-5300 specification. The modules are unbuffered, non-ECC and run at 1.8 V with CL5 5-5-5 timing. They use a 200-pin form factor and carry the Computer Memory Solutions CM256645300SO part number for Apple MacBook and MacBook Pro systems.

200-pin DDR2 upgrade for mid-2007 Macs

The kit suits owners of mid-2007 Apple Mac mini (model MB138LL/A, A1176, Macmini2,1) and compatible MacBook Pro units that accept DDR2-667 SO-DIMMs. Buyers whose machines require a different pin count, voltage or DDR generation cannot use this memory.

DDR2-667 (PC2-5300) speed rating

The decisive specification is the DDR2-667 speed rated as PC2-5300; the system must support this exact data rate and 200-pin SO-DIMM slot type for the modules to function.

Questions about this item

Will these 200-pin DDR2 SO-DIMM modules fit the memory slots in a Mac mini model A1176?

Yes, the kit is listed as compatible with the Mac mini A1176 (model MB138LL/A, Macmini2,1) from mid-2007, which uses 200-pin DDR2 SO-DIMM slots.

What is the correct way to seat the 200-pin modules so they lock into the MacBook Pro slots?

Insert each module at an angle until the gold contacts are fully hidden, then press down firmly until the side retention clips click into the notches on both edges.

When should the two 2 GB sticks be replaced if the system becomes unstable?

Test with a memory diagnostic tool if crashes or corruption appear; these unbuffered DDR2 modules have no heat spreader and run at 1.8 V, so they can last many years under normal use.
