Capacity and configuration

This kit provides 128GB of DDR5 memory across four 32GB registered DIMMs. It is built for Dell Precision 5860 tower workstations that require ECC protection and registered signalling for data integrity.

Speed and limits

The modules run at 4800 MT/s with a CAS latency of 40 and operate at 1.10V. Registered 2Rx4 organisation adds a clock cycle for address buffering, which supports large capacities but reduces raw latency compared to unbuffered alternatives.

Included components

The package contains only the four 288-pin RDIMMs; no heat spreaders, cables or software utilities are supplied. Installation relies on the workstation's own firmware and the owner's manual for configuration.

Questions about this item

Will the 288-pin DDR5 4800 RDIMM kit install alongside existing DDR5 modules in my Precision 5860?

The kit uses standard 288-pin DDR5 RDIMM form factor at 4800 MT/s CL40 1.10 V. Mixing speeds or ranks can force the system to run at the slowest common settings, so populate identical modules for best stability.

How can I verify the 128 GB kit is running at DDR5 4800 CL40 with ECC active after installation?

Enter the BIOS or use a tool like CPU-Z and confirm the memory reports 4800 MT/s, CL40 timings, 1.10 V, and ECC enabled across all four 32 GB modules.

Does the MR38400-324K4 package include only the four 32 GB RDIMMs, or are heat spreaders and cables also supplied?

The box contains the four 32 GB 2Rx4 ECC registered RDIMMs only; no heat spreaders, cables or additional accessories are included.
