Dell PowerEdge XR4000w upgrade kit

This 64 GB kit contains two 32 GB DDR4 3200 registered DIMMs built for Dell PowerEdge XR4000w, XR4510c and XR4520c rack servers. ECC and registered buffering protect data integrity in mission-critical workloads. The modules run at 1.2 V with CL22 latency and use a 2Rx8 organisation.

IT teams running virtualisation or databases

Administrators who need maximum capacity per slot in the supported PowerEdge models will benefit from the 32 GB density. Buyers who want unbuffered UDIMMs, non-ECC memory or speeds above DDR4 3200 cannot use this kit. Systems outside the listed Dell series are not validated.

Tool-free DIMM installation in minutes

Each 288-pin RDIMM seats directly into the server memory slots without cables or adapters. The most common issue is mixing registered and unbuffered modules, which prevents boot. Always populate slots according to the Dell service manual for the specific XR chassis.

Questions about this item

What Dell server models are required to use this 64 GB DDR4 3200 ECC RDIMM kit?

This kit is validated for Dell PowerEdge XR4000w, XR4510c and XR4520c rack servers.

How will this CL22 3200 MHz registered memory interact with any existing 3200 MHz RDIMMs already installed in those servers?

All modules will operate at the common 3200 MHz speed and CL22 latency; the registered design ensures stable operation when mixed with identical-spec RDIMMs.

After installation, how can I confirm the kit is running at the rated 3200 MHz with ECC active?

Check the system BIOS or iDRAC memory configuration screen; it should show 64 GB total, 3200 MT/s, ECC enabled and registered mode.
