16 GB DDR3L kit for iMac 27-inch Late 2015

This 16 GB kit contains two 8 GB SODIMM modules built to the DDR3L 1866 standard at 1.35 V. The 204-pin unbuffered design matches the memory slots fitted to the iMac Retina 5K 27-inch Late 2015 model. Computer Memory Solutions tests each kit for direct compatibility with that system.

Suits owners of the specified iMac who need

The CL13 timing and 2Rx8 organisation follow the platform requirements, so the modules install without configuration changes. Buyers whose iMac already holds 32 GB across four slots cannot add more capacity. Systems that demand ECC or registered DIMMs will not accept this kit, and any computer outside the named model should be checked against its own service manual first.

Two slots free equals simple 16 GB upgrade

The iMac Late 2015 27-inch ships with four SODIMM sockets and a 32 GB ceiling. If two sockets are still vacant, this 16 GB pair fills them and reaches the halfway mark. When all four sockets are occupied the only path to more memory is replacing existing modules, which this kit does not address.

Questions about this item

How can I confirm the 16GB kit is running at 1866MHz with CL13 timings after installing it in my iMac?

Open About This Mac and click System Report, then select Memory to verify each 8GB module shows 1866MHz DDR3L and the CAS latency reads 13-13-13.

What is included in the box and do I need any tools or extra parts to install the two SODIMMs?

The package contains two 8GB 204-pin DDR3L SODIMM sticks; no tools or additional components are required for the iMac's user-accessible memory compartment.

Should I choose this 16GB (2x8GB) kit or a different capacity for the 27-inch Late 2015 iMac with four slots and a 32GB maximum?

This 16GB kit fills two of the four slots, leaving room to add another 16GB kit later if you want to reach the 32GB limit.
