Dell PowerEdge XR-series ECC RDIMM

This 64GB DDR4 3200 registered module is built for Dell PowerEdge XR4000w, XR4510c and XR4520c rack servers that require ECC RDIMM memory. It delivers 64GB in a single 288-pin DIMM running at 1.2V with CL22 latency.

ECC registration and 2Rx4 organisation

Error-correcting code and registered buffering protect data integrity under sustained server workloads. The dual-rank 2Rx4 layout allows the memory controller to address higher density per channel without adding extra modules.

Standard 288-pin DDR4 installation

The DIMM seats in any compatible DDR4 RDIMM slot; no extra cables or drivers are required. Servers that do not support registered ECC DDR4 or that limit rank population per channel will not accept this module.

Questions about this item

Will the 64 GB 2Rx4 RDIMM ever need a firmware update or chip replacement?

No firmware or chip replacement is required; the module is a fixed hardware component validated for the listed Dell servers.

What thermal limit appears first when the module runs at 3200 MHz continuously in a Dell PowerEdge XR4510c?

The 1.2 V DDR4 DRAM is rated for standard JEDEC operating temperatures; sustained loads stay within that envelope without throttling.

How much extra heat and power does a single 64 GB stick add when the server runs all day?

At 1.20 V the module draws nominal DDR4 power and has no heat spreader, so it relies on the chassis airflow already designed for the XR4000w series.
