Dell PowerEdge XE9640 RDIMM upgrade

This 16 GB DDR5 registered DIMM is built for the Dell PowerEdge XE9640 server platform. It delivers ECC protection and registered signalling for multi-socket stability in enterprise workloads. The module operates at 1.1 V with a CAS latency of CL40.

Sustained-load behaviour with ECC RDIMM

Registered buffering reduces electrical load on the memory controller during continuous throughput. ECC corrects single-bit errors in real time, preventing silent data corruption under long-running compute tasks. The 4800 MT/s data rate maintains consistent bandwidth across extended sessions.

Replacing slower or non-ECC memory in Dell servers

This module upgrades from lower-speed DDR5 or non-ECC unbuffered DIMMs that lack error correction. The jump is worth it when workloads demand data integrity and the platform requires registered modules for memory capacity scaling.

Questions about this item

How much power does this 1.1 V DDR5 RDIMM draw when the server runs continuously?

The module operates at 1.1 V, the standard DDR5 voltage, so power draw stays within the platform's registered DIMM budget for all-day workloads.

What server configuration is required before installing this 288-pin ECC registered module?

A Dell PowerEdge XE9640 with an available DDR5 RDIMM slot and BIOS that supports 4800 MT/s registered ECC memory.

Will this CL40 1Rx8 module run alongside other DDR5 RDIMMs already in my Dell server?

Yes, it matches the DDR5 4800 RDIMM specification; populate remaining slots with identical speed, rank and ECC type for optimal stability.
