System-Specific 16GB Kit for 27-inch iMac Late 2015

This 16GB kit contains two 8GB DDR3L SO-DIMM modules built for the iMac 3.3GHz quad-core Retina 5K, 27-inch, Late 2015. It targets owners of that specific model who need to reach the factory memory ceiling without guesswork.

DDR3L SO-DIMM limits at 1866 MHz and 1.35V

The iMac Late 2015 accepts DDR3L SO-DIMM at 1866 MHz (PC3L-14900) with CL13 timing and 1.35V operation. Modules that exceed this speed, use standard 1.5V DDR3, or require ECC will not be recognised by the system firmware.

Two 8GB sticks fill half the slots for 16GB total

The computer provides four SO-DIMM sockets with a 32GB maximum. This kit occupies two slots with 2Rx8 unbuffered modules, leaving two sockets free. Buyers who want the full 32GB capacity must add a second matching kit.

商品問答

Should I choose the 16 GB kit or the 32 GB maximum for my Late 2015 iMac 27-inch?

The kit provides 16 GB total in two 8 GB modules; the iMac supports up to 32 GB across its four slots, so you can add another identical kit later if you need the full 32 GB.

What does the 1866 MHz DDR3L rating mean once installed in the iMac?

The modules run at 1866 MHz with CL13 timings at 1.35 V, matching the iMac's memory controller specification for DDR3L 1866 (PC3L-14900) operation.

Does the 204-pin SO-DIMM interface limit speed or capacity in this iMac?

The 204-pin DDR3L SO-DIMM form factor is the native interface for the Late 2015 27-inch iMac, allowing the full 1866 MHz speed and up to 8 GB per module across the four slots.
