16 GB DDR4-2933 ECC Registered DIMM
This 16 GB DDR4-2933 module is built for servers and workstations that require error-correcting registered memory. The dual-rank 2Rx8 organisation and CL21 latency suit multi-socket platforms where data integrity matters more than low latency. It plugs into standard 288-pin DDR4 slots and runs at the PC4-23400 data rate.
Sustained throughput with registered buffering
The on-DIMM register reduces electrical load on the memory controller, allowing larger populations of modules to run at the rated 2933 MT/s without signal degradation. ECC circuitry corrects single-bit errors on the fly, preventing silent data corruption during long compute jobs or virtualization workloads. Dual-rank density keeps the memory controller busy across both ranks for steady bandwidth.
Registered ECC requirement decides fit
This part only works in systems that explicitly support registered ECC DDR4; consumer desktop boards and most unbuffered workstation platforms will not post with it installed. Verify the motherboard or server manual lists registered ECC DDR4-2933 before purchase.

Preguntas sobre este artículo
How much heat and power does this 16GB DDR4-2933 registered ECC module generate during continuous server operation?
The module uses standard DDR4 voltage and registered buffering to reduce electrical load on the memory controller. Dual-rank organisation and CL21 timing keep power draw consistent with other PC4-23400 parts. Adequate chassis airflow is recommended for sustained workloads.
What motherboard features are required to use this 288-pin registered ECC memory?
The board must provide 288-pin DDR4 DIMM slots, support registered (buffered) modules, and enable ECC in the BIOS. Consumer desktop chipsets typically lack these features, so a server or workstation platform is needed.
Can this PC4-23400 dual-rank stick be mixed with other DDR4 speeds in a multi-channel server?
The module runs at DDR4-2933 with CL21 latency. When mixed with slower DDR4, the system will downclock all channels to the lowest common speed and loosest timings. Population rules for registered dual-rank DIMMs still apply.
