Apple notebook upgrade

This 8 GB kit contains two 4 GB SO-DIMM modules built for Apple notebooks that accept DDR3 1600 memory. It is intended for owners of compatible Mac portables who want to increase installed memory without compatibility guesswork.

204-pin SO-DIMM build

Each module uses the 204-pin SO-DIMM form factor and operates at the standard 1.5 V for DDR3 1600. The low-profile design fits the tight confines of Apple notebook slots and the CAS latency of 11 matches the timing expected by those systems.

Replaces lower-capacity DDR3 kits

The kit upgrades machines that shipped with 4 GB or 6 GB of DDR3 memory, letting the operating system keep more applications and browser tabs resident. The jump is worthwhile when the current configuration forces frequent paging to storage.

Questions about this item

What speed does the DDR3 1600 SO-DIMM run at in an Apple notebook?

The modules operate at 1600 MT/s (PC3-12800) with CL11 timing at 1.5 V, the standard DDR3 voltage for these Mac models.

Will the 204-pin SO-DIMM fit my MacBook Pro or iMac memory slot?

Yes, the 204-pin DDR3 SO-DIMM form factor matches the factory slots in compatible Apple notebooks and all-in-ones.

Do I need to install the two 4 GB sticks as a matched pair?

Install both modules together; the kit is tested as a matched pair so the memory controller can run in dual-channel mode.
