Apple iMac and Mac Mini compatible kit

This 32GB kit contains four 8GB DDR4 SODIMM modules built for Apple iMac and Mac Mini systems. It runs at 2666MHz with a CAS latency of 19 and operates at 1.2V. The unbuffered, non-ECC design suits standard desktop workloads in those machines.

260-pin SODIMM form factor for slotted systems

Each module uses the 260-pin DDR4 SODIMM layout found in compatible iMac and Mac Mini models. The kit fills four slots to reach 32GB total capacity. No heat spreaders are fitted, so the modules fit tight spaces without added height. Rank is 1Rx8 per module.

Tested under sustained load for stability

Modules are stress tested under continuous load to verify reliable operation over time. The 1.2V rating keeps power draw steady during extended sessions. Chips come from major OEM sources such as Samsung, Micron or Hynix. This kit does not serve systems requiring ECC or registered memory.

Questions about this item

Will the CL19 latency become a bottleneck during sustained heavy workloads?

CL19 is the rated CAS latency for these DDR4 2666 modules; it sets the baseline access delay for every memory operation under load.

How much heat or noise should I expect from this kit when running continuously?

These SODIMMs have no heat spreader and operate at 1.20 V, so they add minimal thermal load and produce no audible noise themselves.

Does my Mac already have four free 260-pin SODIMM slots for this 32 GB kit?

The kit contains four 8 GB modules that each plug into a 260-pin DDR4 SODIMM slot; your system must provide four available slots.
