iMac and Mac Mini memory kit
This 16 GB kit contains two 8 GB DDR4 2666 MHz SODIMM modules built for Apple iMac and Mac Mini systems. It targets owners who need more memory for everyday multitasking or heavier workloads.
260-pin unbuffered non-ECC build
Modules use major OEM chips from Samsung, Micron or Hynix and run at 1.2 V with CL19 latency. The 260-pin SODIMM form factor fits the factory slots without adapters or heat spreaders.
DDR4 2666 ceiling
Speed is fixed at DDR4 2666 (PC4-21300) so the memory cannot run faster than the platform allows. Buyers who want higher frequencies or ECC error correction must choose a different kit.
