OWC 16GB DDR4 2666MHz PC4-21300

Increase system headroom where it matters most: multitasking, large application loads, and memory-bound workflows. This OWC 16 GB DDR4 module runs at 2,666 MHz and is specified as PC4-21300, giving compatible desktops and workstations the bandwidth they need for responsive operation under sustained use. Built as a 288-pin DIMM with CL19 latency, 1.20 V operating voltage, and non-ECC unbuffered architecture, it fits the requirements of standard desktop memory platforms that call for DDR4 UDIMM support. That makes it a practical upgrade path for IT teams refreshing aging systems or standardizing memory across user fleets. For procurement teams, the value is straightforward: a single 16 GB module can extend the useful life of a desktop without replacing the platform. For technical buyers, the appeal is in the specification discipline — DDR4, 2,666 MHz, CL19, and lifetime warranty coverage. It is a clean-fit component for environments that need predictable compatibility and dependable capacity, not marketing claims.
