Rank 2Rx4

  • 16 GB capacity supports demanding server workloads
  • DDR4 2666 speed delivers PC4 21300 bandwidth
  • ECC registered design corrects errors for data integrity
  • 2Rx4 dual-rank layout maximises density per channel
  • Validated across 200 000 system configurations

Server Memory Module

This 16 GB DDR4 2666 registered ECC module targets administrators upgrading or repairing enterprise servers that require registered memory with error correction. It fits 288-pin DDR4 slots and operates at PC4 21300 speed.

Registered ECC Design

The registered buffer reduces electrical load on the memory controller, allowing larger populations of modules per channel. On-die ECC detects and corrects single-bit errors, protecting data integrity in always-on workloads.

288-Pin DDR4 Installation

Insert the module into a compatible DDR4 registered DIMM slot until the retention clips engage. Mixing registered and unbuffered modules, or populating slots in an unsupported order, will prevent the system from posting.

Questions about this item

How often does the 16GB 2Rx4 ECC Registered DDR4 module need replacement in a continuous server workload?

The module has no scheduled replacement interval; solid-state DRAM lasts until a correctable error rate exceeds the platform threshold or a hard failure occurs.

What limit appears first when the 2666 MT/s registered DIMM runs at full load for hours?

The JEDEC-defined 2666 MT/s data rate and registered buffer latency set the throughput ceiling before thermal throttling engages.

How much heat and power does the 288-pin DDR4 2666 stick produce when populated all day?

Standard DDR4 2666 registered 2Rx4 DIMMs typically draw a few watts each and stay within JEDEC thermal limits with normal server airflow.
