NEMIX RAM 32GB DDR4 2933 PC4-23400 CL21 2Rx4 1.2V ECC RDIMM Dell PowerEdge M640 VRTX

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.
