32GB DDR4 Kit for 2017 iMac 27-inch

This 32GB kit contains four 8GB DDR4 2400 SODIMM modules built for the 2017 iMac 27-inch with Retina 5K display (model ID iMac 18,3). It runs at 1.2V with CL17 latency and uses 260-pin unbuffered non-ECC memory. The kit targets owners of this specific iMac who want the maximum supported memory configuration.

Suits iMac 18,3 owners; not for other Macs or PCs

The modules are validated for the iMac 18,3 configurations listed, including 3.4 GHz, 3.5 GHz, 3.8 GHz Core i5 and 4.2 GHz Core i9 models. Buyers with different iMac years, smaller screen sizes, MacBook models, or Windows laptops requiring DDR4 SODIMM should look elsewhere because the compatibility testing is specific to this 2017 27-inch Retina 5K iMac.

260-pin DDR4 2400 SODIMM form factor decides fit

The memory uses the 260-pin DDR4 SO-DIMM physical interface operating at 2400MHz (PC4-19200) with CL17 timing at 1.2V. If your system requires a different pin count, DDR generation, voltage, or form factor, this kit will not install or function correctly.

商品問答

Does this 32 GB kit fit the four SO-DIMM slots of an iMac 18,3?

Yes, the kit contains four 8 GB modules that match the 260-pin DDR4 SO-DIMM form factor used in the 27-inch 2017 iMac 18,3.

Will these CL17 modules run stably alongside the original Apple memory if I keep some of it?

The iMac 18,3 has four slots; this kit fills all of them, so no original modules remain installed.

How can I confirm the memory is recognised at 2400 MHz after installation?

Open About This Mac or System Report and verify the speed shows 2400 MHz for each of the four 8 GB modules.
