OWC 64GB DDR4 2666MHz ECC Registered RDIMM memory upgrade

SKU CH-MQ78-ANZAB

64GB DDR4 2666MHz ECC registered RDIMM module for Dell PowerEdge C6420, R440, R540 and T440 servers

  • Capacity64GB
  • Type288-Pin DDR4 ECC RDIMM
  • SpeedDDR4 2666 (PC4 21300)

  • Voltage1.2V
  • ECCYes

Capacity 64GB

  • 64GB capacity for high-density server workloads
  • ECC registered design protects data integrity in critical applications
  • 2666MHz DDR4 speed with CL19 latency for responsive performance
  • 2V operation reduces power draw in dense configurations
  • Validated for Dell PowerEdge C6420, R440, R540 and T440 systems

Server memory upgrade

This 64GB DDR4 2666MHz ECC registered RDIMM is built for Dell PowerEdge C6420, R440, R540 and T440 servers. It targets administrators who need to expand capacity in these specific platforms. The module will not work in standard desktop computers or consumer motherboards.

ECC registered operation

Error-correcting code and register buffering protect data integrity under sustained server workloads. These features also prevent mixing with unbuffered memory, so all slots must use registered DIMMs. The design follows JEDEC and RoHS standards for a warranty-safe upgrade.

DDR4 2666 interface limits

The PC4-21300 interface runs at 2666MHz CL19 and steps down to 2133MHz or 2400MHz when the platform requires it. It cannot exceed the rated speed or operate on non-DDR4 systems. Capacity is fixed at 64GB per module.

이 상품에 대한 질문

Will the 64GB DDR4 2666MHz ECC RDIMM need replacement under normal server workloads?

ECC registered DDR4 modules are solid-state with no moving parts and are rated for continuous operation; replacement is only needed if a module fails or capacity requirements grow beyond 64GB.

What limits sustained throughput on this 288-pin CL19 registered DIMM?

The CL19 latency at 2666MHz and the registered buffer add one cycle per command, so the memory controller’s request rate becomes the first bottleneck under heavy sustained loads.

How much heat and power does the 1.2V 2Rx4 module produce running all day in a Dell PowerEdge R440?

At 1.2V the module draws minimal power and has no heat spreader, so it relies on the server’s forced airflow; typical registered DDR4 thermals stay well within chassis cooling limits.
