Compatible Dell PowerEdge XR8610t

This 128GB kit contains two 64GB DDR5 4800 RDIMM modules built for Dell PowerEdge XR8610t and XR8620t rack servers. The registered ECC design with 2Rx4 organisation targets IT teams running virtualisation, database or edge workloads that require error correction and high density.

Straightforward DIMM installation

Installation follows the standard 288-pin DDR5 RDIMM procedure and typically takes minutes per module. The server manual must be consulted for supported population rules, maximum capacity per CPU and any BIOS version requirements before the upgrade is attempted.

DDR5 4800 registered ECC limits

The DDR5 4800 interface delivers 38400 MT/s throughput with CL40 latency at 1.1V. Registered operation adds a clock cycle for signal integrity, and the 2Rx4 rank layout constrains maximum module density on platforms with rank-per-channel limits.

Questions about this item

How can I confirm the 128GB kit is running at 4800MHz with CL40 after installing it in my Dell PowerEdge XR8610t?

Enter the system BIOS or iDRAC interface after boot and verify the memory speed shows 4800MHz and CAS latency reads CL40 for the installed 2Rx4 modules.

What exactly ships in the box and do I need any extra brackets or cables for the XR8620t?

The package contains two 64GB 288-pin DDR5 ECC RDIMM modules totalling 128GB; no additional brackets, cables or heat spreaders are required for installation.

Should I choose the 2Rx4 128GB kit or a different rank configuration for my XR8610t?

This 2Rx4 128GB (2x64GB) kit matches the Dell-qualified specification for the XR8610t and XR8620t; select it when you need the full 128GB capacity at 4800MHz.
