16GB Dual-Channel DDR4 Kit

This OWC kit provides 16GB of desktop memory as two 8GB modules. It is built for standard desktop PCs, workstations and compatible NAS systems that accept unbuffered DDR4 DIMMs. The modules run at the JEDEC-standard 1.2V.

DDR4 2133MHz JEDEC Standard

The memory operates at 2133MHz with a CAS latency of 15, matching the PC4-17000 JEDEC specification. As an unbuffered, non-ECC design it follows the baseline DDR4 standard without extended profiles or higher-voltage operation.

Unbuffered Non-ECC 288-Pin Form Factor

These are 288-pin UDIMMs without error correction or registered buffers. That form factor determines whether the modules fit and function in a given desktop or workstation motherboard.

Questions about this item

Should I pick the 16GB dual-channel kit or a single 16GB module?

The 16GB kit contains two 8GB modules that run together in dual-channel mode, doubling the data path compared with a single stick of the same total capacity.

What does the 2133MHz CL15 rating deliver in everyday use?

At 2133MHz with CL15 timing the modules transfer data at the PC4-17000 rate, giving responsive multitasking and faster application loading on compatible desktop platforms.

Will the 288-pin DDR4 interface limit the speed on my motherboard?

The 288-pin unbuffered DDR4 design follows the JEDEC PC4-17000 standard, so the memory will operate at 2133MHz on any board that supports that specification.
