  • 16 GB kit upgrades iMac to 16 GB total
  • DDR3L 1600 speed matches Late 2013 iMac spec

Tailored for Apple iMac 27-Inch Late 2013

This 16 GB kit is built specifically for the Apple iMac "Core i7" 3.5 27-Inch (Late 2013). It matches the factory slot layout and electrical requirements so the system recognises the memory immediately. Buyers upgrading other iMac models or non-Apple laptops should look elsewhere because the pin-out and voltage are tuned for this platform.

DDR3L 1600 at 1.35 V with CL11 timing

The modules run at DDR3L 1600 (PC3L 12800) with a CAS latency of 11-11-11 at 1.35 V. That exact speed and voltage combination is the deciding factor; a standard 1.5 V DDR3 stick will not operate correctly in this iMac. The 204-pin SO-DIMM form factor and unbuffered, non-ECC design complete the compatibility profile.

Two matched 8 GB sticks enable dual-channel

The kit contains two 8 GB sticks (2Rx8) that install as a pair, allowing the memory controller to run in dual-channel mode for higher bandwidth. No heat spreaders are included, keeping the low profile required by the slim iMac chassis. The package supplies only the memory modules; no tools, adapters or software are bundled.

Questions about this item

Will the 1600 MHz speed actually run at that rate in the Late 2013 iMac?

The Late 2013 27-inch iMac supports DDR3-1600 memory, so these modules will operate at their rated 1600 MHz speed.

Does the DDR3L 1.35 V specification work with the iMac's memory slots?

Yes, the iMac's DDR3 slots accept 1.35 V DDR3L modules; the lower voltage is fully compatible and runs without changes.

Will the 204-pin SO-DIMM sticks fit the four memory slots in the 27-inch Late 2013 iMac?

The 27-inch Late 2013 iMac has four 204-pin SO-DIMM slots, and this 2x8 GB kit occupies two of them for a 16 GB total.
