What this kit is and who it fits

This 4 GB kit contains two 2 GB DDR3 SO-DIMM modules rated at 1066 MHz with CL7 timings. It is built for the Apple MacBook "Core 2 Duo" 2.4 13-inch Mid-2010 model MC516LL/A and uses the 204-pin form factor required by that system.

Check your MacBook before ordering

Verify your MacBook is the Mid-2010 13-inch model identified as MC516LL/A or MacBook7,1 with the A1342 enclosure. The machine has two memory slots and Apple officially supports up to 8 GB, so this kit fills both slots at half the official maximum.

Thermals noise and power in normal use

The modules run at the standard 1.5 V DDR3 voltage without a heat spreader, relying on the MacBook's internal airflow. Unbuffered non-ECC chips at CL7 produce no audible noise and add minimal power draw during typical workloads.
