128GB RDIMM kit for Dell PowerEdge servers

This Samsung bundle provides 128GB of DDR4 registered memory across four 32GB modules. It is designed for IT administrators upgrading compatible Dell PowerEdge servers including the M640, R440, R540, R640, R740, R740XD, T440 and T640 models. The 288-pin RDIMM form factor ensures proper fit in supported server motherboards.

Sustained load behaviour with registered DDR4

Registered DIMMs include a register that buffers address and command signals, reducing electrical load on the memory controller during continuous operation. Running at 2666MHz with PC4-21300 compliance and CL19 latency, the kit delivers stable throughput for virtualisation, database and compute workloads that keep memory subsystems saturated for extended periods. The registered design helps maintain signal integrity across all four populated slots.

Verify server model and slot availability

Confirm your exact PowerEdge model appears in the supported list before ordering. Ensure the server has four free DDR4 RDIMM slots to accommodate the full kit. Check the system documentation for maximum supported capacity per socket and any population rules that dictate slot filling order. This memory is not suitable for workstations or consumer motherboards that require unbuffered DIMMs.

Frågor om den här produkten

How much power do the four 32 GB DDR4 RDIMMs draw when the server runs continuously?

The modules are standard DDR4 PC4-21300 RDIMMs rated at 2666 MHz with CL19 latency; power draw depends on the server platform and load, so consult the Dell PowerEdge documentation for exact figures.

What server hardware is required for this 128 GB kit to function?

The kit is validated for Dell PowerEdge M640, R440, R540, R640, R740, R740XD, T440 and T640 servers with 288-pin DDR4 RDIMM slots.

Can the 2666 MHz CL19 RDIMMs share memory channels with slower DDR4 modules already installed?

All modules will operate at the speed of the slowest installed DIMM; mixing different speeds or latencies is possible but the system will downclock to the lowest common specification.
