48GB DDR5 Registered Server Memory

This Kingston KSM56R46BS4PMI-48HMI module delivers 48GB of DDR5 5600 registered ECC memory for server and workstation motherboards. It operates at 1.10V with CL46 latency and a single-rank 1Rx4 organisation. The 288-pin RDIMM form factor fits compatible DDR5 registered DIMM slots. On-die ECC and x80 ECC provide data-integrity features for mission-critical workloads.

Suited for servers needing registered ECC DDR5.

This module suits servers and workstations that require registered DDR5 memory with ECC for stability. Builders using consumer desktop motherboards that accept only unbuffered non-ECC DIMMs cannot use this part. Systems lacking DDR5 registered DIMM support should look at alternative memory types. The 48GB capacity fits high-density configurations where registered buffering is mandatory.

Deciding spec: registered DDR5 ECC RDIMM

The single specification that decides fitment is the registered DDR5 ECC RDIMM interface. Only motherboards with DDR5 registered DIMM slots supporting ECC can accept this module. Unbuffered or non-ECC platforms will not work. Verify your platform documentation for registered DDR5 ECC support before purchase.

Questions about this item

Does my motherboard need to support 288-pin DDR5 RDIMM slots and registered memory for this 48GB module to work?

Yes, the module is a 288-pin DDR5 RDIMM with registered buffering, so the motherboard must provide DDR5 RDIMM slots that accept registered DIMMs and operate at 1.10V.

Can I mix this CL46 5600MT/s registered ECC module with older DDR5 ECC UDIMMs running at 4800MT/s?

No, registered RDIMMs and unbuffered UDIMMs cannot be mixed on the same platform; the motherboard must support registered memory exclusively for this 1Rx4 module to function.

How can I verify the module is running at 5600MT/s with CL46 timings and ECC active after installation?

Check the BIOS memory information or use a tool such as dmidecode to confirm the speed shows 5600MT/s, timings read 46-45-45, and ECC status reports as enabled for this 48GB DIMM.
