Mac Memory Upgrade

This 4 GB DDR3 SO-DIMM is built for Apple notebooks that accept 204-pin modules at 1333 MT/s. It installs without tools and meets the voltage and timing specifications those systems expect.

Buyer Fit

Suits owners of compatible Mac laptops who need a single 4 GB stick to replace a failed module or fill an empty slot. Not for machines that require a different pin count, voltage range, or memory generation than the one specified here.

Deciding Spec

The module runs at DDR3 1333 (PC3-10600) with CAS latency 9 and dual-voltage 1.35 V/1.5 V operation; if your Mac calls for that exact speed and timing, this part will work.
