64GB DDR5 4800 ECC RDIMM for Dell Precision 5860

This single 64GB module runs at 4800MT/s with CL40 latency and 1.10V operation. It uses registered ECC 2Rx4 architecture on a 288-pin DDR5 form factor. The part is validated for the Dell Precision 5860 tower workstation. Samsung, Micron or Hynix chips provide the underlying memory density.

Best for registered ECC memory upgrades

Buyers needing unbuffered UDIMM modules or non-ECC memory for consumer platforms cannot use this registered RDIMM. Systems limited to lower DDR5 speeds or smaller maximum module capacities should verify motherboard documentation before purchase. Workstations requiring registered ECC memory in a 64GB DDR5 4800 module are the intended fit.

DDR5 4800 registered ECC with 2Rx4 organisation

The registered 2Rx4 layout at 4800MT/s CL40 determines compatibility with the Dell Precision 5860 memory controller. This specific rank and buffer configuration must match the platform requirements for the module to initialise and operate correctly.

Questions about this item

Does my Dell Precision 5860 workstation need a DDR5-capable motherboard to use this 4800 MHz RDIMM?

Yes, this module is DDR5 4800 PC5-38400 and requires a DDR5 motherboard; the Dell Precision 5860 Tower Workstation provides that platform.

Can I add this 2Rx4 registered ECC module alongside existing DDR5 RDIMMs already installed in the system?

This 64 GB 2Rx4 CL40 1.10 V registered ECC DDR5 RDIMM can be installed with other DDR5 RDIMMs; matching speed, voltage, rank and ECC type gives the most reliable operation.

How can I confirm the module is running at 4800 MHz with ECC active after installation?

Enter the system BIOS or use an OS tool such as dmidecode to verify the memory speed shows 4800 MT/s and ECC status reports as enabled for the installed 64 GB RDIMM.
