8 GB DDR3 1333 MHz kit for MacBook Pro

This 8 GB kit contains two 4 GB DDR3 1333 MHz SO-DIMM modules built to the PC3-10600 standard. It is engineered for the Apple MacBook Pro "Core i7" 2.2 15-inch Early 2011 (model MC723LL/A, MacBookPro8,2, A1286). The unbuffered, non-ECC sticks run at 1.5 V with CL7 7-7-7 timings.

Suits owners of the named 2011 MacBook Pro.

The kit matches the exact 204-pin DDR3 SO-DIMM slot layout and voltage of that specific MacBook Pro. Buyers with a different Mac model, a Windows laptop, or a desktop motherboard should look elsewhere because the firmware compatibility guarantee covers only the listed Apple system.

204-pin DDR3 SO-DIMM form factor decides fit

The modules use the 204-pin DDR3 SO-DIMM interface required by the Early 2011 15-inch MacBook Pro. If your device uses a different pin count, a different DDR generation, or a DIMM instead of SO-DIMM, this kit will not install.

Questions about this item

Will the 204-pin SO-DIMM modules fit the memory slots in the MacBook Pro 15-inch Early 2011?

Yes, the kit uses 204-pin DDR3 SO-DIMMs which match the slot type used in the MacBook Pro 15-inch Early 2011.

What is the correct way to seat both 4GB sticks so the MacBook Pro 15-inch Early 2011 recognises the full 8GB?

Insert each module at an angle until the gold contacts disappear, then press down firmly until the side clips click into place on both sticks.

If a module fails years later, what replacement does the lifetime warranty from Computer Memory Solutions cover?

The lifetime warranty from Computer Memory Solutions covers a replacement module of the same 4GB DDR3 1333MHz CL7 specification.
