System-specific DDR4 upgrade

This 8 GB DDR4-2666 module is built for MSI Z370 motherboards including Krait Gaming, PC Pro, SLI Plus, Tomahawk, M Gaming Pro AC and M Mortar. It fits 288-pin DIMM slots and runs at 1.2 V without ECC or buffering. Buyers who need more than 8 GB per slot or want registered memory cannot use this kit.

Sustained-load behaviour

Rated at CL19 with 19-19-19 timings, the module operates at its specified latency continuously rather than only in short bursts. The unbuffered 2Rx8 organisation and major-brand chipset maintain stable throughput during extended workloads. Systems that demand lower latency or ECC error correction will not meet those requirements with this stick.

DDR4 platform limits

Four slots on the supported boards allow a maximum of 64 GB total capacity when populated with matched modules. All installed memory runs at the speed of the slowest module or the CPU's memory controller limit. A 64-bit operating system is required to address more than 4 GB of installed RAM.

Questions about this item

How much heat does the 1.2V DDR4 2666MHz CL19 module produce when running all day?

The 1.2V DDR4 2666MHz CL19 module operates at standard DDR4 voltage without a heat spreader, so it runs cool enough for continuous use inside a typical desktop case with normal airflow.

Which motherboard must I already own for this CMS CM1024642666DIMM stick to work?

This module is validated for MSI Z370 KRAIT GAMING, Z370 PC PRO, Z370 SLI PLUS, Z370 TOMAHAWK, Z370M GAMING PRO AC and Z370M MORTAR boards with 288-pin DDR4 slots.

If I add this 2666MHz CL19 stick to slower DDR4 modules already installed, what speed will the system run at?

All memory in the system will run at the slowest installed module speed or the CPU capability, so this 2666MHz CL19 stick will downclock to match your existing slower DDR4.
