16GB (1x16GB) Dual Rank

HPE 672631-S21-RFB is a 16GB server memory module supplied as one 16GB DIMM. Its single-module configuration provides a straightforward way to add memory capacity to a compatible system.

The module uses DDR3-1600 / PC3-12800R memory and has a 1600 MHz clock speed. It is registered (buffered) and supports ECC, with CAS latency 11. This combination is intended for server and enterprise workstation environments that use registered DDR3 memory.

Its dual-rank x4 design and 240-pin DIMM form factor describe the module’s configuration and physical interface. This part is a focused memory upgrade for systems designed for this class of memory.
