1TB DDR5-4800 ECC RDIMM kit

This 1TB kit contains sixteen 64GB DDR5-4800 registered DIMMs built for Dell PowerEdge XE8640 rack servers. Each module runs at 1.1V with CL40 latency and 2Rx4 organisation. ECC and register buffering protect data integrity in continuous workloads. The 288-pin form factor matches the server's memory slots exactly.

Suited for Dell XE8640 expansion only

IT teams scaling memory in a Dell PowerEdge XE8640 will find full compatibility and validated stability. Systems needing unbuffered UDIMMs, non-ECC modules, lower voltages or different pin counts cannot use this kit. Workstations or servers outside the Dell XE8640 platform should verify qualification before purchase.

16 x 64GB registered DDR5 population

The kit populates sixteen slots with 64GB dual-rank registered modules, delivering maximum supported capacity per channel. Builds requiring fewer than sixteen modules, single-rank density or consumer UDIMM form factor must select a different configuration. No other capacity or rank option is included in this package.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the memory slots in a Dell PowerEdge XE8640 rack server?

Yes, the kit is built for that server and each of the 16 modules uses the standard 288-pin DDR5 RDIMM form factor required by the platform.

What is the correct order for populating the 16 slots when installing this 1 TB kit?

Follow the Dell PowerEdge XE8640 memory population guide; the usual mistake is skipping the prescribed slot sequence, which prevents the system from recognising all 16 modules.

How can I tell if one of the 64 GB modules needs replacement later?

Run a full memory diagnostic such as MemTest86 or the Dell built-in test; persistent correctable ECC errors or uncorrectable failures on a specific module indicate it should be swapped out.
