Capacity & fit

This kit provides 512GB of DDR5 memory in four 128GB registered DIMMs built for the Dell Precision 5860 tower workstation. It targets professionals who need maximum ECC capacity for large datasets, virtualization or scientific workloads on that specific platform.

Upgrade path

The modules replace lower-capacity DDR5 RDIMMs or fill empty slots to reach the workstation’s supported memory ceiling. The jump is worthwhile when your workload exceeds the capacity of smaller kits and the application can use the additional address space.

DDR5 4800 limits

The PC5-38400 standard runs at 4800 MT/s with CL40 latency at 1.10V, which sets the bandwidth and timing floor for this generation. Systems that only support lower DDR5 speeds will downclock the kit, and platforms requiring faster JEDEC profiles cannot be satisfied by this speed grade.

Questions about this item

Does the 288-pin DDR5 RDIMM form factor fit the Dell Precision 5860 tower workstation memory slots?

Yes, the 288-pin DDR5 RDIMM modules are the correct form factor for the Dell Precision 5860 tower workstation memory slots.

What is the correct order to populate the four 128GB modules across the eight memory channels?

Install the four 128GB modules in the four slots designated for the first processor, following the channel sequence shown in the Dell Precision 5860 service manual.

Will the 1.1V operating voltage require any BIOS adjustment on the Precision 5860?

The 1.1V DDR5 modules operate at the standard JEDEC voltage, so the Precision 5860 BIOS will configure them automatically without manual changes.
