iMac 27" Late 2015 32GB DDR3 Kit
This 32GB kit contains two 16GB DDR3 1866 SODIMM modules built for the Apple iMac 27-inch Late 2015 with Retina 5K display. It runs at 1.35V with CL13 latency and uses 204-pin unbuffered non-ECC chips from major OEM suppliers.
Suits owners of that specific iMac model
The kit matches the factory speed and voltage for the Late 2015 27-inch iMac, so it installs directly into the two SODIMM slots. Systems that require ECC, registered modules, a different pin count or a different DDR generation will not accept this memory.
Deciding spec: 1866MHz DDR3 204-pin SODIMM
The modules operate at DDR3 1866 (PC3-14900) in the 204-pin SODIMM form factor. If your Mac calls for that exact speed and pin layout, the kit fits; if the machine needs another speed, voltage or form factor, this memory will not work.

Questions about this item
Will my iMac 27" Late 2015 need a firmware update before it recognises the 1866 MHz DDR3 SODIMMs?
No firmware update is required; the Mac's memory controller detects the 1866 MHz DDR3 modules at boot and configures them automatically.
Can I keep one of the original 8 GB sticks and add a single 16 GB module from this kit?
The kit is validated as a matched 2 x 16 GB pair; mixing capacities or ranks can prevent dual-channel operation and may cause instability.
How do I confirm the memory is running at 1866 MHz with CL13 timing after installation?
Open About This Mac → System Report → Memory; each slot should show 16 GB, DDR3, 1866 MHz, and the timing will read CL13.
