Targeted MacBook Pro upgrade

This 8 GB kit contains two 4 GB DDR3 1333 MHz SODIMM modules built for the Apple MacBook Pro "Core i7" 2.8 13" Late 2011. Each stick uses a 204-pin layout, runs at 1.5 V and carries CL7 7-7-7 timings. The unbuffered non-ECC design matches the factory specification for this notebook.

Replaces the original 4 GB or 8 GB configuration

The machine ships with two slots and a 16 GB ceiling, so this kit fills both sockets and doubles the stock 4 GB amount. Builders who already run 8 GB in a mismatched pair gain matched 2Rx8 ranks and guaranteed CMS compatibility. The jump is worth it when the system slows under multitasking or virtual machines.

Fits the 13-inch Late 2011 logic board directly

No heat spreader means the modules sit low under the keyboard deck without clearance issues. The 1.5 V rating draws standard power from the existing regulator. Buyers who need more than 16 GB total capacity or who use a different MacBook generation cannot use this kit.

Questions about this item

Will these 204-pin DDR3 SO-DIMM modules fit the two memory slots in my MacBook Pro 13-inch Late 2011?

Yes, the kit matches the 204-pin DDR3 SO-DIMM form factor and the system has two slots supporting up to 16 GB total, so both 4 GB sticks install directly.

What is the correct way to seat the modules so the Mac recognises the full 8 GB?

Insert each stick at an angle into the slot, then press firmly until the side clips click; the common mistake is stopping before the clips engage, which leaves the module partially connected.

When should I expect to replace these CL7 1.5 V modules?

They carry a limited lifetime warranty from CMS and have no moving parts; replacement is only needed if a stick fails or you upgrade beyond the 16 GB maximum the machine accepts.
