256 GB DDR5 4800 ECC RDIMM kit for Dell PowerEdge

This sixteen-module kit delivers 256 GB of DDR5 4800 registered ECC memory for the Dell PowerEdge XE9640 rack server. Each 16 GB module operates at 1.1 V with CL40 latency and a 1Rx8 organisation. The 288-pin RDIMM form factor fits the server's registered DIMM slots. Modules use major OEM Samsung, Micron or Hynix chips.

Server administrators expanding XE9640 capacity

The kit suits IT teams scaling memory in Dell PowerEdge XE9640 servers for virtualisation, database or HPC workloads that demand registered ECC reliability. Buyers needing unbuffered UDIMM modules for workstations or consumer motherboards cannot use this registered kit. Systems limited to lower DDR5 speeds or different pin counts are also incompatible.

Registered ECC RDIMM requirement

The single specification that decides fit is the registered ECC RDIMM interface; the XE9640 memory controller only accepts registered modules with error-correcting code. Unbuffered or non-ECC DDR5 DIMMs will not function in this platform.

商品問答

Does the Dell PowerEdge XE9640 need a specific BIOS revision before the 16 modules can be recognised?

The kit is built to Dell XE9640 specifications; follow the server manual for any required firmware update before installing the 16 modules.

Will the 1.1 V CL40 registered ECC modules run alongside any existing RDIMMs already installed in the server?

Mixing ranks or speeds is not recommended; for stable operation populate all slots with identical 1Rx8 4800 modules from this kit.

How can I confirm the full 256 GB is running at 4800 MT/s with ECC active after installation?

Check the system BIOS or iDRAC memory inventory — it should show 16 × 16 GB, 4800 MT/s, ECC enabled, registered.
