4GB DDR3 1333 SODIMM for select 2010–2011 Macs

This module is a 4GB DDR3 1333 MHz (PC3-10600) SO-DIMM with 204 pins, unbuffered, non-ECC, 1.50V, 2Rx8 organisation, built with major-brand chips. It is engineered specifically for the Apple systems listed in the compatibility data.

Suits owners of listed MacBook Pro.

Buyers with MacBook Pro 13-inch, 15-inch or 17-inch from Early or Late 2011, iMac 21.5-inch or 27-inch from Mid 2010 or Mid/Late 2011, or Mac mini Mid 2011 can install this module directly. Anyone whose Mac requires a different DDR generation, a different pin count, registered or ECC memory, or a voltage other than 1.50V will not be able to use this part.

DDR3 1333 MHz (PC3-10600) speed rating

The memory operates at DDR3 1333 MHz, labelled PC3-10600, which is the exact speed specification the supported Macs expect. If a system demands a higher or lower DDR3 data rate, this module will not match the required timing and should not be purchased.
