Dell PowerEdge XR7620 DDR5 kit

This 256GB kit contains eight 32GB DDR5 4800 CL40 ECC registered DIMMs built for the Dell PowerEdge XR7620 rack server. The modules run at 1.1V and use a 2Rx8 organisation with 288-pin connectors. They are designed for enterprise workloads that require error correction and registered signalling.

Compatibility checklist

Verify that your XR7620 currently accepts DDR5 4800 registered ECC memory and that eight DIMM slots are free for this 8x32GB configuration. Confirm the system BIOS supports 2Rx8 modules at this density before ordering. Ensure the server’s memory population rules allow filling all selected channels with registered DIMMs.

What the kit changes

Installing the full 256GB set expands the server’s memory capacity in a single step and maintains ECC protection across all populated slots. The matched 2Rx8 modules keep timing consistent at CL40 without mixing ranks. No heat spreaders are included, so airflow in the chassis must handle thermal management.

Questions about this item

Does the kit include all eight 32 GB modules or must I buy them separately?

The package contains the full 256 GB kit with eight 32 GB DDR5 RDIMM modules so nothing else needs to be purchased for this upgrade.

Should I choose the 2Rx8 rank option or is a different rank available for the PowerEdge XR7620?

This kit uses 2Rx8 organisation and is the configuration validated for the Dell PowerEdge XR7620; no alternative rank is offered in this part number.

What does the 4800 CL40 rating mean for actual server performance?

The modules run at 4800 MT/s with CAS latency 40 at 1.1 V, delivering the standard DDR5 bandwidth and error-correction required by the XR7620 memory controller.
