OWC 16GB DDR4 for HP EliteDesk

This 16GB DDR4 module is built for HP EliteDesk 705 G3 and 800 G2 small-form-factor and tower systems. It targets owners of those desktops who need more memory for everyday workloads. Buyers with other platforms or laptops cannot use this UDIMM.

Straightforward UDIMM installation

The 288-pin unbuffered DIMM drops into a standard desktop slot without tools or configuration changes. Common issues arise only when mixing speeds or exceeding the board’s slot count, so verify free slots before purchase.

DDR4 2133 sets the practical ceiling

The module runs at 2133 MHz with CL15 latency and 1.2 V, so the system cannot operate the memory faster than that JEDEC rate. Builders needing higher bandwidth or ECC error correction must choose a different specification.
