16GB DDR4 desktop module

This OWC module adds 16GB of DDR4 memory to a desktop system. It runs at 2133MHz with a CAS latency of 15 and operates at 1.2V. The unbuffered 288-pin UDIMM fits standard desktop DIMM slots. It is a non-ECC part designed for general computing and multitasking.

Sustained load behaviour

Under continuous workloads the module maintains its rated 2133MHz speed and CL15 timings. The 1.2V operating voltage keeps power draw steady during extended sessions. Without a heat spreader the chips rely on case airflow to stay within thermal limits. JEDEC compliance ensures stable operation over long periods.

DDR4 interface limits

The DDR4 standard at 2133MHz delivers a peak transfer rate of PC4-17000. This bandwidth ceiling is set by the memory controller and the JEDEC specification for this speed grade. Higher frequencies would require a different module or platform support. The 288-pin form factor is fixed for DDR4 UDIMMs.

Questions about this item

Will this single 16GB module fit a standard desktop motherboard slot?

Yes, it uses the 288-pin UDIMM form factor that matches every consumer desktop DDR4 slot.

Can I install this alongside my existing DDR4 sticks without changing voltage settings?

The module runs at the standard 1.2V JEDEC voltage, so it will operate at default BIOS settings with other DDR4 memory.

Does the CL15 latency at 2133MHz suit everyday office and multitasking workloads?

CL15 at 2133MHz is the baseline JEDEC timing for DDR4 and provides responsive performance for typical desktop applications.
