Target System

This 16 GB kit is built for the Apple iMac Retina 5K 27-inch (Late 2015) MK472LL/A. It delivers two 8 GB DDR3L SODIMM modules rated at 1866 MHz with CL13 timing. The kit suits owners who want to maximise the factory memory slots in this specific all-in-one desktop.

Build Integration

Each stick uses the 204-pin SO-DIMM form factor and runs at 1.35 V without ECC or buffering. The system accepts up to 64 GB across four sockets, so this pair leaves two slots free for future expansion. Buyers who need the full 64 GB capacity will require two additional modules of the same specification.

Thermals and Power

The modules operate at the standard DDR3L voltage of 1.35 V and have no heat spreader. Power draw stays low in normal desktop workloads, and the bare PCB design relies on the iMac’s internal airflow for cooling. Acoustic impact is negligible because the memory adds no moving parts.

Questions about this item

How many SO-DIMM slots does the compatible iMac have and what is its maximum memory capacity?

The supported iMac has 4 slots and accepts up to 64 GB total.

Does this unbuffered DDR3L kit generate noticeable heat or fan noise during all-day use?

No heat spreader is fitted and the modules run at 1.35 V, so thermal output stays low in normal operation.

Which specific Apple model must I already own for this 204-pin DDR3L 1866 MHz kit to work?

It is validated for the iMac Retina 5K 27-inch Late 2015 MK472LL/A.
