Compatible MacBook Pro Memory Kit

This 8 GB kit contains two 4 GB DDR3 SO-DIMM modules built for the Apple MacBook Pro 15-inch Early 2011. The memory runs at 1333 MHz with CL7 timing and operates at 1.5 V. It is an unbuffered, non-ECC design using major-brand components.

Suited for 2011 MacBook Pro upgrades

The kit matches the 204-pin DDR3 specification required by the MacBookPro8,2 and A1286 identifiers listed in the compatibility data. It will not work in systems that need a different pin count, voltage, or memory generation, nor in desktop DIMM slots.

1333 MHz DDR3 speed rating

The decisive specification is the DDR3 1333 (PC3 10600) speed grade combined with the 204-pin SO-DIMM form factor. If the target MacBook Pro requires this exact speed and pin layout, the kit is the correct part.

Questions about this item

Will these 204-pin DDR3 SO-DIMM sticks fit the memory slots in my Early 2011 15-inch MacBook Pro?

Yes, the 204-pin DDR3 SO-DIMM form factor matches the two memory slots in the MacBook Pro 15 Early 2011 (MacBookPro8,2 / A1286).

What is the correct way to seat the modules, and what step do people often miss?

Insert each stick at an angle until the gold contacts disappear, then press down firmly until both side clips click — the click confirms the module is fully locked.

If a module fails years from now, what replacement does the maker provide?

Computer Memory Solutions backs the kit with a limited lifetime warranty when purchased directly from them.
