System-Specific DDR5 ECC RDIMM Kit

This 64 GB kit contains two 32 GB DDR5 4800 registered DIMMs built for the Dell PowerEdge R760xa. Each module runs at 1.1 V with CL40 latency and provides ECC error correction for server workloads. The 2Rx8 organisation and 288-pin form factor match the platform's memory slots.

Suited For And Not Suited For

IT teams expanding a compatible Dell rack server with validated ECC registered memory will find this kit matches the required specification. Systems that need unbuffered DIMMs, non-ECC modules, a different pin count or a speed grade other than 4800 MT/s cannot use these sticks.

Deciding Specification

The registered ECC RDIMM interface combined with DDR5 4800 speed and 2Rx8 organisation is the single specification that determines whether this kit fits the target server.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the Dell PowerEdge R760xa memory slots?

Yes, the 288-pin DDR5 RDIMM form factor matches the R760xa DIMM slots exactly.

Do I need to populate the R760xa memory channels in a specific order when adding this 2Rx8 kit?

Install the two 32 GB modules in the channel pair indicated in the R760xa service manual; skipping a channel or mixing ranks is the common error.

Will the Samsung, Micron or Hynix chips on these modules require any firmware updates or periodic replacement?

No firmware updates are needed for the DRAM chips; the modules are solid-state with no moving parts and no scheduled replacement interval.
