48 GB DDR5 6400 RDIMM

This 48 GB DDR5 6400 registered DIMM delivers ECC protection and a 1.1 V operating voltage for server platforms that require registered memory. The single-module kit uses a 2Rx8 organisation and conforms to the PC5-51200 standard with CL52 latency. It is intended for installation in compatible server motherboards that support DDR5 RDIMMs.

Who this suits and who it does not

This module suits administrators upgrading or populating servers that specify DDR5 6400 registered ECC memory with a 288-pin interface. It is not for desktop PCs, workstations that require unbuffered UDIMMs, or systems limited to lower DDR5 speeds or non-ECC configurations. Buyers needing multiple modules to fill all channels should order additional units separately.

Capacity and headroom

The 48 GB capacity provides substantial memory headroom for virtualisation hosts, database nodes and compute-intensive workloads running on supported DDR5 server platforms. Performance scales with the number of populated channels, so a single module leaves bandwidth unused on multi-channel architectures. Workloads that exceed 48 GB per socket will require additional modules or higher-capacity RDIMMs.

Questions about this item

Does this module require a server motherboard with DDR5 6400 RDIMM slots?

Yes, it needs a 288-pin DDR5 RDIMM socket that supports 1.1 V operation and ECC registered memory at 6400 MT/s.

Will the 2Rx8 rank layout work if I keep existing 1Rx8 DDR5 modules in the same channel?

Mixing 2Rx8 and 1Rx8 ranks in one channel is not recommended; the memory controller may downclock or disable ECC for that channel.

How can I verify the module runs at 6400 MT/s with CL52 after installation?

Check the BIOS memory information screen or run a tool such as dmidecode; it should report 6400 MT/s, CAS 52, 1.1 V and registered ECC status.
