512GB DDR5 ECC RDIMM Kit

This 512GB kit comprises four 128GB DDR5 4800MHz registered DIMMs built for Dell PowerEdge R760xa servers. It targets IT teams upgrading memory capacity in compatible rack-mounted platforms. ECC and registered buffering protect data integrity in mission-critical workloads.

Capacity and headroom

The 512GB total (4 x 128GB) provides substantial headroom for virtualisation, large databases and in-memory analytics. Four 4Rx4 ranks per module maximise density within the 288-pin form factor. Workloads exceeding 512GB will require additional DIMM slots or higher-capacity modules not included in this kit.

DDR5 4800 interface limits

The PC5-38400 standard delivers 4800MT/s at 1.1V with CL40 latency. Bandwidth and latency are fixed by the DDR5 4800 specification; faster speeds or lower latencies need memory controllers and modules rated beyond PC5-38400. Systems locked to 4800MT/s cannot utilise higher-speed DDR5 grades.

Points forts

  • 512GB total capacity powers memory-intensive server workloads
  • Four 128GB modules populate quad-channel architecture efficiently
  • DDR5 4800 speed delivers high-throughput data transfer
  • ECC registered design corrects errors for mission-critical reliability
  • 1V operation reduces power draw per module

Questions sur cet article

Will the 4Rx4 DDR5 4800 registered modules work with other RDIMMs already installed in a PowerEdge R760xa?

The kit provides four 128 GB DDR5 4800 CL40 1.1 V 4Rx4 registered DIMMs; Dell's memory population rules for the R760xa require identical rank and speed per channel, so mixing different ranks or speeds is not supported.

How can I confirm the 512 GB kit is running at DDR5 4800 with ECC active after installation?

Enter the system BIOS or iDRAC and verify the memory speed shows 4800 MT/s, total capacity reads 512 GB, and ECC status reports enabled for each of the four modules.

Does the MR38400-744K4 box contain only the four 288-pin RDIMMs or are cables or brackets included?

The package includes four 128 GB DDR5 288-pin ECC registered RDIMMs; no cables, brackets or additional hardware are supplied.
