System-specific DDR3 SO-DIMM kit

This 8 GB kit contains two 4 GB modules built to the DDR3 1333 standard with CL7 timing and 1.5 V operation. It is assembled for the 21.5" Intel Core i3/i5 iMac and uses 204-pin unbuffered, non-ECC SO-DIMMs from a major brand chipset.

The kit matches the factory slot count and maximum per-slot capacity for that model. Builders working on any other Mac, on a PC laptop, or on a desktop that requires registered or ECC memory should look elsewhere.

204-pin DDR3 1333 SO-DIMM interface

Only systems that accept 204-pin DDR3 1333 unbuffered non-ECC modules can use this kit; the pin count, voltage and signalling standard are fixed and not interchangeable with other memory generations.
