Dell Precision 5860 DDR5 ECC kit

This 512GB kit contains eight 64GB DDR5 4800 CL40 registered ECC RDIMMs built for the Dell Precision 5860 tower workstation. It targets professionals who need maximum error-corrected memory capacity for compute-intensive workloads on that specific platform.

Installing the eight modules in the correct slots

Installation follows the workstation's documented DIMM population order; the modules are keyed 288-pin DDR5 and seat with standard pressure. Common issues arise when slots are filled out of sequence, when a module is not fully latched, or when the system BIOS has not been updated to recognise the full 512GB configuration.

Before ordering verify your workstation model

Confirm the system is a Dell Precision 5860 tower and that the current BIOS revision supports 64GB registered DDR5 RDIMMs at 4800 MT/s. The kit requires eight free DIMM slots and operates at 1.1V; mixing with unbuffered or non-ECC modules will prevent the system from posting.

Questions about this item

How can I confirm the kit is running at DDR5 4800 CL40 after installation?

Check the memory speed and CAS latency in the system BIOS or a tool such as CPU-Z; they should report 4800 MT/s and CL40 for each of the eight 64 GB modules.

What does the 512 GB kit contain and is anything else required?

The box includes eight 64 GB 288-pin DDR5 RDIMMs; no extra cables, brackets or heat spreaders are supplied or needed for the Dell Precision 5860.

Should I choose this 8 × 64 GB kit or a different capacity for the Precision 5860?

Select this 512 GB kit when the workload needs the maximum supported capacity across all eight DIMM slots; choose a smaller kit if you need fewer modules or lower total memory.
