128GB DDR5 ECC RDIMM for Dell R660

This 128GB DDR5 4800 registered DIMM delivers ECC protection and 4Rx4 organisation for Dell PowerEdge R660 servers. It operates at 1.1V with CL40 latency and uses major OEM DRAM chips. The module targets IT professionals who need validated compatibility for mission-critical workloads.

Sustained load behaviour

Registered buffering and on-die ECC maintain data integrity during continuous heavy traffic typical of virtualisation and database tiers. The 4Rx4 layout increases bank parallelism to help sustain throughput when all ranks are active. Modules are stress-tested under load before shipment to confirm stability.

DDR5 4800 interface limits

The PC5-38400 interface caps peak bandwidth at the rated 4800 MT/s transfer rate. Single-module capacity of 128GB fits within the 288-pin RDIMM form factor without a heat spreader. Buyers needing higher per-slot density or faster speeds must select a different DDR5 specification.

Perguntas sobre este artigo

How much power does each 128GB 4800MHz DDR5 4Rx4 module draw at 1.1V during continuous operation?

The module operates at 1.1V, the standard DDR5 voltage, which helps limit power draw per DIMM compared to earlier generations; exact wattage varies with workload and server power management settings.

What server platform is required to use this 288-pin ECC registered DDR5 RDIMM?

It is validated for the Dell PowerEdge R660 and requires a DDR5-capable server motherboard that supports 288-pin ECC registered RDIMMs at 4800MHz.

Can this 4Rx4 registered DDR5 DIMM share channels with older DDR5 RDIMMs of different rank or speed in the same server?

Mixing ranks or speeds on the same channel is not recommended; the server memory controller will typically down-clock all modules to the lowest common speed and may require specific population rules for 4Rx4 modules.
