48GB DDR5 RDIMM for servers

This Kingston KSM56R46BD8PMI-48HMI module provides 48GB of DDR5 5600 registered ECC memory. It operates at 1.10V with CL46 latency and a 2Rx8 rank structure. The 288-pin RDIMM form factor is built for enterprise motherboards that require registered, error-correcting DIMMs.

Suited for registered ECC platforms.

This memory targets servers and workstations that mandate registered ECC DDR5 RDIMMs. Systems needing unbuffered UDIMMs, non-ECC modules or SO-DIMM form factors cannot use this part. Buyers without registered ECC support in their platform should look elsewhere.

48GB capacity per module

Each DIMM delivers a single 48GB DDR5 5600 registered ECC rank configuration. This density determines how many modules are required to reach a target system memory total. Verify the motherboard's maximum capacity per slot and total supported memory before purchase.

  • DDR5 5600MT/s speed delivers high data throughput
  • CL46 latency with 46-45-45 timing optimises response

Questions about this item

How can I verify the 48GB DDR5 5600MT/s CL46 module is running at its rated 5600 MT/s speed and 1.10V voltage after installation?

Enter the server BIOS or UEFI and confirm the memory frequency shows 5600 MT/s (PC5-44800) with timings 46-45-45 at 1.10V; the registered ECC RDIMM will also report its 2Rx8 rank and on-die ECC status in the memory information screen.

What ships with the KSM56R46BD8PMI-48HMI 48GB DDR5 RDIMM and what extra parts are required?

The box contains the single 288-pin DDR5 registered DIMM only; no heat spreader is included and no separate components are needed — the module draws power from the server DIMM slot at VDD 1.1V, VDDQ 1.1V, VPP 1.8V and VDDSPD 1.8–2.0V.

When should I choose this 48GB 2Rx8 DDR5-5600 CL46 registered ECC module over other capacities or ranks?

Select this 48GB dual-rank x8 module when your server requires maximum capacity per slot with registered ECC at DDR5-5600 CL46; the 2Rx8 organisation and on-die ECC suit platforms that populate each channel with two ranks for optimal bandwidth.
