Dell PowerEdge R860 Compatible DDR5 ECC RDIMM

This 16GB registered DDR5 module is built for Dell PowerEdge R860 rack servers that require ECC memory. It operates at 4800MT/s with a CL40 latency and runs at 1.1V. The single-rank 1Rx8 organisation uses major OEM DRAM from Samsung, Micron or Hynix. It targets IT administrators upgrading or repairing mission-critical enterprise systems.

DDR5 4800 PC5-38400 Registered Signal Limit

The registered buffer adds one clock cycle of latency but reduces electrical load on the server memory controller, allowing larger populations per channel. Speed is fixed at the JEDEC base rate of 4800MT/s with PC5-38400 bandwidth; no XMP or overclock profiles are supported on this platform. ECC correction protects data integrity but does not increase raw throughput beyond the rated specification.

288-Pin RDIMM Without Heat Spreader

The bare green PCB fits standard 288-pin DDR5 RDIMM slots and relies on server chassis airflow for cooling. Absence of a heat spreader keeps module height low, avoiding interference with CPU heatsinks or cable routing in dense 1U or 2U racks. Registered signalling and ECC require a compatible motherboard; consumer desktop boards will not recognise or boot with this module.

Questions about this item

Is the 16 GB DDR5 4800 module the right capacity for my Dell PowerEdge R860?

The 16 GB DDR5 4800 module matches the listed capacity and speed for the Dell PowerEdge R860, giving one 1Rx8 registered DIMM per slot.

What does the 4800 MT/s speed deliver once the module is installed in the server?

The module runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.1 V, providing the rated throughput for registered ECC workloads.

Does the 288-pin RDIMM interface limit the memory bandwidth in the R860?

The 288-pin DDR5 RDIMM interface operates at the specified 4800 MT/s; registered buffering and ECC are handled on-module per the server's memory controller.
