32GB DDR5 ECC RDIMM for Samsung servers

This 32GB DDR5 4800 registered DIMM is built for Samsung server and workstation platforms that require ECC memory. The module operates at 1.1V with a CL40 latency and a single 1Rx4 rank configuration. IT professionals select it for mission-critical environments where data integrity and system stability are mandatory.

Single-module upgrade with major OEM components

The package delivers one 288-pin RDIMM assembled with Samsung, Micron or Hynix components and stress-tested under load before shipment. No heat spreader is included, allowing dense slot population in compatible chassis. Registered buffering reduces electrical load on the memory controller for reliable operation in multi-DIMM configurations.

CL40 latency at DDR5 4800 speed

The CAS latency of CL40 at 4800 MT/s determines the module's timing profile for the memory controller. Systems that demand a different latency or voltage will not support this part. Buyers who need non-ECC unbuffered memory or a different rank structure must choose another product.

Questions about this item

Will the 1Rx4 ECC RDIMM require any firmware updates or periodic reseating during its service life?

The module is a standard 288-pin DDR5 registered DIMM with on-die ECC; once seated in a compatible slot it operates without firmware intervention and does not need scheduled reseating.

Which electrical or thermal limit is reached first when the DIMM runs continuously at 4800 MT/s and CL40?

The JEDEC-specified 1.10 V operating voltage and the 4800 MT/s data rate are the primary electrical limits; sustained loads stay within these parameters without triggering throttling.

How much extra heat and acoustic load does a single 32 GB DDR5 4800 RDIMM add to a rack server running all day?

At 1.1 V the module draws only a few watts, producing minimal heat that is handled by normal chassis airflow and adding no audible noise.
