Apple MacBook Pro 13" Early 2011 upgrade

This 16GB kit contains two 8GB DDR3 SODIMM modules built for the Apple MacBook Pro 13" Early 2011. It targets owners of the MC700LL/A or A1278 models who need the full 16GB capacity Apple officially supports. The unbuffered, non-ECC design matches the notebook's memory controller requirements.

1333MHz CL9 DDR3 specification

Each module runs at 1333MHz (PC3-10600) with a CAS latency of CL9 and a 9-9-9 timing sequence. The 1.5V operating voltage and 204-pin SO-DIMM form factor are the decisive electrical and mechanical match for this system. A different speed, voltage or pin count will not seat or boot correctly.

Sustained workload behaviour

Under continuous load the modules operate at the rated 1.5V without a heat spreader, relying on the notebook's internal airflow. The dual-rank 2Rx8 organisation delivers stable throughput for long compile, render or virtualisation sessions. Buyers needing 32GB total capacity or registered ECC memory should look elsewhere.

Questions about this item

How does the 1333 MHz speed affect performance in my Early 2011 MacBook Pro?

The modules run at the 1333 MHz DDR3 rate the Early 2011 MacBook Pro 13" uses natively, so the full 16 GB kit operates at the system's standard memory bandwidth without downclocking.

What does the PC3-10600 rating mean for compatibility?

PC3-10600 is the JEDEC designation for DDR3 1333 MHz SODIMMs; it confirms the kit matches the 204-pin unbuffered non-ECC specification the Early 2011 MacBook Pro 13" requires.

Will the 204-pin SODIMM sticks fit the Early 2011 MacBook Pro 13" slots?

Yes, each 8 GB module is a standard 204-pin DDR3 SODIMM, the exact form factor used in the two memory slots of the Early 2011 MacBook Pro 13".
