Quad-channel 64 GB DDR4 kit for 2017 iMac

This 64 GB kit contains four 16 GB DDR4 2400 SO-DIMM modules built to the PC4-19200 standard with CL17 latency and 1.2 V operation. It targets owners of the 27-inch 2017 iMac with Retina 5K display (model identifier iMac 18,3) who need the maximum memory capacity the platform accepts. The unbuffered, non-ECC design matches the factory specification for these machines.

Sustained load behaviour on DDR4 2400 CL17

At the rated 2400 MT/s speed and CL17 timings the modules deliver consistent bandwidth during extended workloads such as video rendering, large dataset analysis or virtual machine hosting. The quad-channel population fills all four slots of the iMac 18,3, allowing the memory controller to interleave accesses across the full 64 GB without down-clocking or throttling under prolonged pressure.

Thermals, noise and power draw

Each module operates at a nominal 1.2 V within a 1.14 V to 1.26 V tolerance, drawing minimal power and producing no audible noise because the parts are purely solid-state. The low-voltage DDR4 design keeps heat output modest inside the compact iMac chassis, and the standard 30 mm by 69.6 mm form factor fits the factory SO-DIMM slots without requiring additional cooling.

この商品に関する質問

How much power and heat does the 1.2V DDR4 2400 kit produce when running all day in a 27-inch iMac?

Each module runs at 1.2V with a tolerance of 1.14V to 1.26V, so total power draw stays low and heat output is minimal inside the slim 27-inch chassis.

What must the iMac already have for this 4×16GB 260-pin kit to work?

The iMac must be a 2017 27-inch Retina 5K model (iMac 18,3) with four free SODIMM slots and firmware that accepts DDR4 2400 CL17 unbuffered non-ECC memory.

Will this quad-channel 64GB kit run alongside the original 8GB or 16GB Apple modules I keep installed?

The kit is validated for iMac 18,3 models using DDR4 2400 CL17 1.2V 260-pin SODIMMs; mixing with original modules of the same spec works, but different speeds or voltages will force the system to run at the lowest common settings.
