16GB DDR4 2666MHz dual-channel kit

This 16GB kit comprises two 8GB DDR4 DIMMs rated at 2666MHz with CL19 timings. It is built specifically for MSI B365M and B450M motherboards including the B365M PRO-VD, B365M PRO-VH, B450I GAMING PLUS AC and B450M GAMING PLUS. The modules run at 1.2V and use unbuffered non-ECC chips.

Sustained-load behaviour

Under continuous workloads the memory operates at its rated 2666MHz speed and 19-19-19 timings without a heat spreader. All installed modules will run at the speed of the slowest module or the processor's memory controller limit. A 64-bit operating system is required to address the full 16GB capacity.

Two-slot maximum capacity constraint

The supported motherboards provide only two DIMM sockets with a maximum system capacity of 32GB. This 16GB kit occupies both slots, leaving no room for further expansion. Builders who need more than 32GB of memory must choose a different platform.

Questions about this item

How much heat and power will the 1.2V DDR4 2666MHz kit draw when the system runs all day?

The modules operate at a standard 1.2V DDR4 voltage with no heat spreader, so they run cool and draw minimal power under continuous load.

What must my motherboard provide for these two 288-pin DIMMs to work?

Your board needs two DDR4 DIMM slots that support 2666MHz (PC4-21300) unbuffered, non-ECC memory at 1.2V; the kit is validated for MSI B365M and B450M models listed in the compatibility data.

If I keep slower DDR4 modules in the other slots, what speed will the whole system run at?

All installed memory will run at the speed of the slowest modules or the CPU’s maximum supported rate, so adding this 2666MHz kit alongside slower sticks will drop the faster pair to that lower frequency.
