128GB DDR5 ECC RDIMM Kit

This 128GB kit comprises two 64GB DDR5 4800 RDIMMs with ECC and registered buffering. It is built for Dell Precision 5860 tower workstations that require registered memory with error correction. The modules suit professional workloads needing large, stable memory capacity.

Simple DIMM installation

The 288-pin DDR5 modules insert into the workstation's RDIMM slots in minutes. Always consult the system manual for the approved population order and any BIOS settings required for registered memory. Systems that accept only unbuffered UDIMMs cannot use these registered modules.

DDR5 4800 registered limits

The DDR5 4800 standard delivers PC5-38400 bandwidth at 1.10V with CL40 latency. Registered DIMMs add a clock cycle for buffering, which slightly raises latency versus unbuffered memory. Workstations limited to lower DDR5 speeds or to UDIMM-only architectures will not support this kit.

Questions about this item

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

Enter the system BIOS or use a tool such as CPU-Z and verify the memory speed reads 4800 MT/s and the CAS latency shows 40.

What exactly ships in the box and is anything else required to install it in a Dell Precision 5860?

The box contains two 64GB 288-pin DDR5 ECC RDIMM modules; no extra cables, brackets or software are needed for the Precision 5860.

Should I choose this 2Rx4 128GB kit or a different capacity for my Precision 5860?

This 2 x 64GB 2Rx4 kit fills two slots with 128GB total; select it when you need that capacity and rank configuration, otherwise pick a kit matching your required total memory and rank layout.
