  • CAS LatencyCL19
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredRegistered

Capacity 16GB

  • 16 GB ECC RDIMM safeguards data integrity in server workloads
  • DDR4 2666 MHz CL19 delivers responsive throughput for heavy multitasking
  • Registered 1Rx4 architecture supports high-density platform scaling
  • 2 V standard voltage lowers power draw per module
  • 288-pin DDR4 DIMM fits compatible server and workstation slots

Server DDR4 ECC RDIMM

This 16GB registered module targets servers and workstations that require error-correcting memory. It will not function in standard desktop or laptop platforms because the memory controller expects registered signalling.

DDR4 2666 registered limits

The DDR4 2666 interface caps bandwidth at the PC4-21300 rating, so throughput cannot exceed that ceiling. Registered buffering adds a cycle of latency, which is normal for multi-module server configurations.

16GB single-rank headroom

A single 1Rx4 module fits one DIMM slot and leaves remaining channels open for expansion. Workloads that exceed 16GB per channel will need additional modules to avoid swapping to storage.

Domande su questo articolo

Is this 16 GB module the right capacity for a single-slot upgrade?

Yes, the module provides 16 GB in a single 288-pin DIMM, so one stick adds that full amount to a compatible server or workstation.

Will the rated 2666 MHz speed actually run at that frequency in my system?

The module is specified at DDR4 2666 (PC4-21300) with CL19 at 1.2 V; the memory controller in your server or workstation will determine the final operating speed.

Does the registered ECC interface limit the maximum usable speed?

The RDIMM uses a registered ECC interface at DDR4 2666; the platform's memory controller caps the practical throughput, not the module itself.
