Overview

The Kingston Server Premier KSM56R46BS8-16HA is a 16GB registered DDR5 module for servers and workstations. It runs at 5600 MT/s, carries the PC5-5600 rating and uses SK hynix A-die DRAM.

A 1Rx8 layout means one rank built from x8 chips. Organization is 2G x 80-bit (EC8) across 288 pins, and error correction works at two levels: ECC on the module and on-die ECC within each DDR5 device.

Electrically it runs at 1.1 V with CAS latency 46 and timings of 46-45-45. Kingston rates it for 0 to 95 °C.

At 16GB, it fits builds that populate many channels at a moderate total, or a like-for-like swap for a failed DIMM with the same part number.

Conditions: New and Refurbished, each with 1 year or 3 years of warranty, and Used with 90 days.
