MacBook Pro 13.3" memory kit

This 8GB kit from Computer Memory Solutions contains two 4GB DDR3L SODIMM modules rated at 1600MHz with CL11 timings. It runs at 1.35V and uses the 204-pin form factor required by the specified Apple notebook.

Suitable for the MD101LL/A model

The kit matches the factory specification for the MacBook Pro 13.3" 2.5GHz Core i5 MD101LL/A, which accepts two SODIMMs up to 8GB total. It is not for machines that only support a single module, require registered or ECC memory, or operate at a different voltage.

DDR3L 1600 CL11 1.35V specification

The decisive figure is the DDR3L 1600 (PC3L 12800) speed at 1.35V with 11-11-11 timing. Systems needing a different DDR generation, a higher voltage, or a different CAS latency will not work with these modules.

Questions about this item

How can I confirm the DDR3L 1600 modules are running at 1.35V after installation?

Open System Report in macOS and check the Memory section; each 4 GB stick should show 1600 MHz speed, 11-11-11 timing and 1.35 V voltage.

What exactly ships in the box and is anything else required?

The package contains two 4 GB 204-pin DDR3L SODIMM sticks; no tools or extra parts are needed for the MacBook Pro 13.3" MD101LL/A upgrade.

Is the 8 GB kit (2×4 GB) the right choice for the MD101LL/A that supports a maximum of 8 GB across two slots?

Yes — the MacBook Pro 13.3" 2.5 GHz Core i5 MD101LL/A caps at 8 GB with two sockets, so this 2×4 GB kit fills both slots to the limit.
