Dell Precision 5860 memory kit

This 1 TB DDR5 registered DIMM kit contains eight 128 GB modules built for the Dell Precision 5860 tower workstation. It targets IT teams and power users who need maximum ECC capacity for virtualization, rendering or large dataset workloads. The kit arrives new and ready for immediate installation.

4Rx4 registered ECC at 4800 MT/s

Each module runs at 4800 MT/s with CL40 latency and 1.10 V, using a 4Rx4 organisation that the workstation's memory controller must support. The registered buffer and on-die ECC protect data integrity in multi-threaded server applications. Buyers whose platforms require a different rank structure or non-ECC memory cannot use this kit.

Eight matched modules simplify deployment

The eight-piece configuration fills all available slots in a single operation, eliminating the need to source individual sticks or verify mixing rules. No heat spreaders are included, so airflow clearance follows the chassis design. Systems that cannot address 1 TB total or that lack 288-pin DDR5 RDIMM slots will not accept this upgrade.

Questions about this item

What does the 4800 MT/s rating mean once the modules are installed in a Precision 5860?

The kit runs at DDR5 4800 (PC5 38400) with CL40 latency, delivering the rated throughput when the workstation's memory controller operates at its supported DDR5 speed.

How does the 288-pin RDIMM interface affect usable bandwidth in this system?

The 288-pin registered DIMM format connects directly to the DDR5 memory controller; the registered buffer adds one cycle of latency but allows the full 4800 MT/s data rate across all eight slots.

What physical clearance is needed to fit the eight 128 GB modules in the tower chassis?

Each module is a standard-height 288-pin DDR5 RDIMM without a heat spreader, so they occupy the eight DIMM slots with no extra vertical clearance beyond the motherboard's slot spacing.
