32GB DDR5 RDIMM server module

This 32GB DDR5 RDIMM module operates at 4800 MT/s with a CAS latency of CL40 and runs at 1.10V. It uses a Samsung chipset in a 2Rx8 registered ECC configuration. The part is designed for server platforms that require registered memory with error correction.

Who this suits and who should look elsewhere

This module suits administrators upgrading or populating servers that accept DDR5 RDIMM memory with ECC. It is not for systems that require unbuffered UDIMM modules, for builds needing non-ECC memory, or for platforms that only support lower DDR5 speeds without registered support.

The specification that decides fit

The registered RDIMM form factor with ECC and a 2Rx8 organisation is the single specification that determines whether this module will work in a given server. Verify that the target platform supports registered DDR5 memory with this rank configuration before purchase.

Questions about this item

How much power does the 1.10V DDR5 4800 RDIMM draw when the server runs continuously?

The module operates at 1.10V, which is the standard DDR5 voltage, so power draw stays within the platform's registered DIMM budget for all-day workloads.

What motherboard feature must my system already have to use this registered ECC memory?

The board needs DDR5 RDIMM slots with registered ECC support; the 2Rx8 organisation and CL40 timing are handled by the memory controller once that slot type is present.

Can I add this 32GB 2Rx8 DDR5 4800 stick alongside slower DDR5 modules I already own?

The memory controller will down-clock all modules to the speed of the slowest installed DIMM, so the 4800 MT/s stick will run at that lower rate when mixed.
