16GB DDR3 SODIMM for iMac Late 2015
This 16 GB DDR3 1866 MHz module is built specifically for the Apple iMac Late 2015 27-inch Retina model 17,1. It targets owners who need a single high-density stick to reach the platform maximum without mixing densities. The 204-pin SO-DIMM form factor and 1.35 V operation match the factory specification exactly.
CL13 timing and 2Rx8 organisation
The module runs at CAS latency 13 with a dual-rank 2Rx8 layout, which the iMac memory controller expects for stable operation at PC3-14900 speed. Major-brand Samsung, Micron or Hynix ICs are used, and every stick is stress-tested under load before shipping. No extra software or heat spreader is included because the system manages thermals internally.
Unbuffered non-ECC 204-pin build
The bare green PCB carries no heat spreader, keeping the profile thin enough for the tight iMac SO-DIMM slot. Gold-edge contacts on the 204-pin connector resist oxidation during the upgrade process. Non-ECC unbuffered design means the module works only in consumer Macs that do not require error-correcting or registered memory.

Questions about this item
Will the 16GB SODIMM need any maintenance or replacement later?
DDR3 modules have no moving parts and require no scheduled maintenance; they are replaced only if a fault develops.
What limit appears first during sustained use?
The 1866MHz speed and CL13 latency set the throughput ceiling; the 1.35V supply defines the thermal boundary under continuous load.
How much noise, heat or power does the module produce running all day?
It draws 1.35V with no heat spreader, so it runs silently and adds minimal heat to the iMac Late 2015 27" enclosure.
