Micron 64GB DDR4 2666MHz SODIMM Kit

This Micron memory kit provides 64GB of DDR4 capacity across two 32GB SO-DIMM modules. It operates at 2666MHz with a CL19 latency rating and uses the standard 260-pin unbuffered form factor. The kit is designed to upgrade compatible systems with a straightforward installation process.

Suits 2019 to 2020 27-inch iMac Retina 5K models

The modules are validated for iMac19,1 and iMac20,1 or iMac20,2 model identifiers covering 3.0GHz through 3.8GHz processor configurations. Builders working on other desktop or laptop platforms should verify their specific model requirements before purchase. This kit does not address needs for registered or buffered memory architectures.

260-Pin DDR4 SO-DIMM Form Factor

The 260-pin DDR4 SO-DIMM interface is the single specification that determines physical and electrical compatibility with the target iMac logic boards. Systems requiring a different pin count, memory generation or module height cannot use these modules. No other specification in the data overrides this fundamental fitting requirement.

商品問答

Should I choose the 64GB kit with two 32GB modules or a different capacity for my 27-inch iMac?

The kit provides 64GB total as two 32GB modules, matching the maximum supported memory for compatible 2019-2020 27-inch iMac models iMac19,1, iMac20,1 and iMac20,2.

What does the 2666MHz speed mean for actual performance in my iMac?

The DDR4 2666MHz (PC4-21300) modules run at the native memory speed supported by the listed iMac models, allowing faster application loading and smoother multitasking without exceeding the system's memory controller limit.

Will the 260-pin SODIMM form factor and DDR4 standard work in my 27-inch iMac?

Yes, the 260-pin DDR4 SO-DIMM modules are the correct physical and electrical interface for the compatible 27-inch iMac models iMac19,1, iMac20,1 and iMac20,2.
