Dell PowerEdge XR7620 DDR5 ECC RDIMM Kit

This 32GB kit contains two 16GB DDR5 4800 CL40 registered DIMMs built for the Dell PowerEdge XR7620 rack server. ECC and registered buffering protect data integrity in mission-critical workloads. The modules operate at 1.1V and use 288-pin DDR5 RDIMM form factor.

Installation and common issues

Installation follows the server manual and typically takes minutes per module. The registered design requires motherboard support for RDIMM; mixing with unbuffered DIMMs will prevent boot. Ensure all slots are populated per Dell's population rules for the XR7620.

DDR5 4800 interface limits

DDR5 4800 (PC5-38400) sets the maximum transfer rate; the memory controller cannot exceed this speed without overclocking, which servers typically disable. CL40 latency is fixed at this data rate. Capacity per channel is limited by the number of 288-pin slots the XR7620 provides.

Perguntas sobre este artigo

How do I confirm the NEMIX RAM kit is running at DDR5 4800 CL40 after installing it in my PowerEdge XR7620?

Enter the system BIOS or use a hardware-monitoring utility to verify the reported speed shows 4800 MT/s and the CAS latency reads CL40; ECC and registered status should also be listed as active.

What does the package contain and do I need any extra parts for the Dell PowerEdge XR7620?

The box includes two 16 GB DDR5 4800 CL40 1.10 V 288-pin ECC RDIMM modules (32 GB total); no additional components are required for installation in the compatible server.

Which capacity kit should I choose if I want 32 GB total for the XR7620?

Select the 32 GB kit (2 × 16 GB, part number MR38400-618K2) — it delivers the full 32 GB in a matched pair validated for the PowerEdge XR7620.
