Dell PowerEdge M640 VRTX compatible DDR4 RDIMM

This 32GB DDR4 registered DIMM is built for Dell PowerEdge M640 and VRTX servers. It carries ECC protection and a 2Rx4 organisation to meet enterprise memory requirements. The module operates at 1.2V and fits 288-pin DDR4 slots. Buyers needing non-ECC or unbuffered memory for consumer platforms cannot use this part.

Sustained load behaviour with ECC registered design

The registered buffer reduces electrical load on the memory controller during continuous operation. ECC corrects single-bit errors and detects multi-bit errors without halting the system. CL21 latency at 2933 MT/s delivers predictable throughput for virtualisation and database workloads. Modules without ECC or registered buffering will not provide the same error resilience under prolonged stress.

DDR4 2933 PC4-23400 interface limits

The DDR4 interface tops out at 2933 MT/s with a PC4-23400 bandwidth ceiling. Registered signalling adds one clock cycle of latency compared with unbuffered modules. Capacity per slot is fixed at 32GB for this rank configuration. Systems requiring higher transfer rates or greater per-slot density must move to a newer memory generation.

Questions about this item

How much power does the 1.2V DDR4 RDIMM draw when the Dell PowerEdge M640 VRTX runs continuously?

The module operates at 1.2V DDR4 standard voltage; actual power draw depends on the server workload and memory controller configuration.

What server hardware is required for this 288‑pin ECC registered DIMM to function?

A Dell PowerEdge M640 or VRTX system with DDR4 RDIMM slots that support 2933 MT/s registered ECC memory.

Will this 2Rx4 CL21 module work alongside existing DDR4 RDIMMs of different rank or latency in the same PowerEdge?

Mixing ranks or CAS latencies is possible only if the platform firmware permits it; consult the Dell memory population guide for the M640/VRTX.
