Dell PowerEdge XR8000-series server memory

This 64GB kit contains four 16GB DDR5 RDIMMs built for Dell PowerEdge XR8000, XR8610t and XR8620t rack servers. Registered ECC operation protects data integrity in mission-critical workloads. Modules run at 4800MT/s with CL40 latency at 1.1V.

Verify registered ECC RDIMM support

Confirm the server accepts 288-pin DDR5 RDIMMs with ECC and registered buffering before ordering. Check the system manual for approved population rules and maximum capacity per channel. Ensure the platform firmware is current for DDR5 4800 operation.

Kit delivers matched quad-channel capacity out

Four identical 1Rx8 modules enable quad-channel bandwidth without mixing batches. Factory stress testing under load reduces the risk of DOA sticks. No heat spreaders are fitted, so airflow in the server chassis handles cooling.

Questions about this item

What comes in the box and does anything else need to be purchased for installation?

The box contains four 16 GB DDR5 4800 ECC RDIMM modules for a total of 64 GB. No extra parts are required; the modules install directly into the server's 288-pin DDR5 slots.

How do I decide between the available capacity or speed options for this kit?

This kit is a single 64 GB configuration running at DDR5 4800 with CL40 latency. If a different capacity or speed is needed, a separate kit matching the server's qualified vendor list must be selected.

What does the DDR5 4800 rating mean once the memory is installed in a Dell PowerEdge XR8610t or XR8620t?

The modules will operate at 4800 MT/s with ECC error correction and registered buffering, delivering the rated PC5-38400 bandwidth at 1.10 V for stable server workloads.
