System-Specific DDR3 SO-DIMM Kit

This 8GB kit contains two 4GB modules built to the DDR3 1600 standard. It is designed for the Apple iMac 27-Inch Late 2012 with a Core i5 2.9 GHz processor. The unbuffered, non-ECC memory installs directly into the system's SO-DIMM slots.

204-Pin DDR3 1600MHz Interface

The modules use a 204-pin SO-DIMM form factor and run at PC3-12800 speed with CL11 timing at 1.5V. This exact specification determines whether the memory will be recognised and run stably in the target iMac. The system accepts up to 32GB across four sockets.

Ideal for Late 2012 iMac 27-Inch Owners

This kit suits owners of the specified Late 2012 27-inch iMac who want a matched pair for dual-channel performance. Buyers with different iMac years, screen sizes or desktop Mac models should verify their exact model identifier before purchasing.

商品問答

What does the 1600MHz rating actually deliver inside the iMac?

The modules run at 1600MHz (PC3-12800) with CL11 timing at 1.5V, matching the iMac's memory controller specification for full rated bandwidth.

How does the 204-pin DDR3 SO-DIMM interface limit the upgrade?

The 204-pin DDR3 SO-DIMM slot accepts only DDR3 modules; the iMac's four sockets support a maximum of 32GB total using this format.

Will the two 4GB sticks fit the Late 2012 27-inch iMac without modification?

Yes, each stick is a standard 204-pin SO-DIMM with no heat spreader, designed to seat directly in the four accessible memory slots of the A1419 chassis.
