System-specific DDR2 SODIMM kit

This 4 GB kit contains two 2 GB unbuffered DDR2-667 SODIMM modules built to the PC2-5300 standard with CL5 5-5-5 timings at 1.8 V. Computer Memory Solutions guarantees compatibility with the listed Apple MacBook Pro 17-inch Core 2 Duo 2.33 GHz system using part number MA611LL/A.

Apple MacBook Pro 17-inch Core 2 Duo owners

The kit matches the exact DDR2 SO-DIMM specification required by the MA611LL/A notebook, so it installs directly into the two 200-pin slots without configuration changes. Builders working on any other platform, or anyone needing ECC, registered modules, higher frequencies or a different pin count, should select a different product.

DDR2-667 (PC2-5300) speed rating

The memory runs at 667 MHz with a CAS latency of 5 and 5-5-5 timings, which is the single specification that determines whether the MacBook Pro will recognise and run the modules at the correct rate.

Questions about this item

Does my MacBook Pro 17-inch Core 2 Duo 2.33 GHz already have a free 200-pin DDR2 SO-DIMM slot for this kit?

The kit fits the MacBook Pro 17-inch Core 2 Duo 2.33 GHz (MA611LL/A) that uses 200-pin DDR2-667 SO-DIMM slots; verify your current slot count before installing.

Will these 1.8 V DDR2-667 modules run stably alongside any original 1.8 V DDR2 memory I keep in the other slot?

Yes, both run at 1.8 V and DDR2-667 (PC2-5300) speeds, so mixing with identical-voltage DDR2 modules is electrically compatible.

How can I confirm the system sees the full 4 GB after I install the two 2 GB sticks?

Open About This Mac or System Profiler; it should report 4 GB total memory at 667 MHz DDR2.
