Computer Memory Solutions CM1024642666DIMM 16GB 2x8GB DDR4 2666 CL19 1.2V

Kit purpose and audience

This 16 GB dual-channel kit uses two 8 GB DDR4 DIMMs running at 2666 MHz with CL19 timings at 1.2 V. It is built for owners of the listed Gigabyte B365M HD3, B450M S2H, H310 D3, H310M A 2.0, H310M DS2 2.0 and H310M DS2 boards who want a straightforward capacity increase without ECC or registration overhead. Builders needing registered or ECC modules, or boards with more than two slots, should look elsewhere.

Capacity and headroom

The paired sticks give 16 GB total and the platform supports up to 32 GB across its two sockets, so one more identical kit would reach the ceiling. At CL19 the modules deliver standard JEDEC bandwidth for everyday workloads and light content creation, but latency-sensitive tasks or heavy multitasking beyond 16 GB will hit the socket limit before the speed limit.

Build integration

Each stick is a 288-pin unbuffered DIMM with no heat spreader, so clearance is minimal and airflow is unrestricted in compact cases. The 1.2 V rating matches default DDR4 voltage, requiring no manual BIOS adjustment on the supported Gigabyte boards. Mixing with slower or faster modules is possible, though the system will run all memory at the lowest common speed.
