Dell PowerEdge XR8000 series ECC RDIMM kit

This 64 GB kit contains two 32 GB DDR5 4800 registered DIMMs built for Dell PowerEdge XR8000 XR8610t and XR8620t rack servers. ECC and registered buffering protect data integrity in mission-critical workloads. System administrators who need validated compatibility for these platforms can install the kit without guesswork. Builders targeting consumer motherboards or non-Dell servers cannot use this memory.

Capacity and headroom

Two ranks per module at CL40 latency deliver 64 GB of registered capacity for virtualisation, database and high-thread-count tasks. The 1.1 V operating voltage keeps power draw low while the DDR5 4800 interface provides baseline bandwidth for current server CPUs. Workloads that scale beyond 64 GB per channel or demand lower latency than CL40 will exceed this kit’s headroom.

Bundled value

The package supplies a matched pair tested together for dual-channel operation, eliminating the risk of mixing loose modules. NEMIX RAM stress-tests each kit under load before shipment, reducing early-life failures in production racks. A lifetime replacement warranty backs the modules, so failed sticks can be swapped without purchasing new kits. No software utilities or additional accessories are included.

Questions about this item

Will these DDR5 4800 CL40 modules run alongside existing DDR5 4800 memory in a Dell PowerEdge XR8610t?

Yes, matched speed and latency let them operate together, but the server requires identical rank and ECC configuration across all populated slots for stable operation.

How can I verify the 2Rx8 ECC registered DIMMs are detected correctly after installation?

Check the system BIOS or iDRAC interface; it will show 64 GB total, DDR5 4800 MT/s, registered ECC mode, and two 32 GB dual-rank modules per channel.

Does the kit include heat spreaders or any extra cables for the XR8620t?

The package contains only the two 32 GB 288-pin DDR5 RDIMMs; no heat spreaders, cables or additional accessories are supplied.
