Model Micron, Full Lock

  • 16 GB DDR5 5600 MT/s for high server throughput
  • ECC registered design protects data integrity in critical workloads
  • CL46 latency at 1.10 V balances speed with efficiency
  • Single-rank 1Rx8 layout simplifies memory population rules

16 GB DDR5 RDIMM for servers

This 16 GB registered DDR5 module is built for server and workstation platforms that require ECC protection. It targets administrators and integrators who need reliable memory for multi-socket systems or virtualization hosts.

Capacity headroom at 5600 MT/s

A single 16 GB rank handles typical virtualization workloads and database buffers with room for additional modules to scale capacity. The CL46 timing and 1.10 V operation deliver standard DDR5 throughput, while the 1Rx8 organization limits maximum density per channel compared to dual-rank alternatives.

Registered ECC with on-die correction

The module combines registered signalling, standard ECC and on-die ECC to detect and correct errors before they reach the CPU. Systems that require unbuffered memory or non-ECC operation cannot use this part.

Questions about this item

Will this 288-pin DDR5 5600 RDIMM work in a system that currently runs DDR5 4800 registered modules?

The module runs at 5600 MT/s with CL46 timing at 1.10 V. The memory controller will negotiate the highest common speed; if the platform supports DDR5 5600 it will operate at that rate, otherwise it will drop to the highest shared JEDEC speed.

How can I verify the ECC and registered functions are active after installation?

Check the BIOS memory information screen — it should report 16 GB, 1Rx8 organisation, ECC enabled and Registered DIMM type. Operating-system tools such as dmidecode or CPU-Z will also show the x80 ECC capability and on-die ECC status.

What ships with the KSM56R46BS8PMI-16MDI and what must be sourced separately?

The box contains the single 16 GB 288-pin DDR5 RDIMM with no heat spreader. No cables, brackets or additional cooling are included; the motherboard must provide a DDR5 RDIMM slot and 1.10 V VDD/VDDQ supply.
