When your server workloads are growing and you can’t afford downtime, you need memory that keeps up without fail. The HPE 835955-B21 16GB DDR4 2666MHz CL19 DIMM 288-pin Ram Module is a high-capacity, error-correcting DIMM designed for HPE ProLiant Gen9 and Gen10, Apollo, Synergy and Blade systems, giving you the reliability and speed required for virtualisation, cloud and large databases.

Key Features of a 2666 MHz DIMM
  • Form Factor: DIMM 288-pin. Fits standard server slots for easy installation.
  • Capacity: 16 GB. Provides ample memory for demanding applications.
  • Speed: 2666 MHz (PC4-21300). Delivers fast data transfer rates to improve performance.
  • Latency Timings: CL19 (19-19-19). Balances speed and stability for reliable operation.
  • Technology: DDR4 SDRAM. Offers higher bandwidth and lower power consumption than previous generations.
  • Data Integrity Check: ECC. Detects and corrects errors automatically, reducing crashes.
  • Features: Dual rank, registered. Enhances signal integrity and supports larger memory configurations.
  • Compatibility: Optimised for HPE Gen9 and Gen10 servers. Guarantees full functionality with supported systems.

Why Choose HPE DIMM

If you manage a data centre or run critical business applications, you know that memory shortages and instability can cripple productivity. Many users struggle to find modules that are both compatible with their HPE hardware and capable of handling intensive workloads. This 16 GB DDR4 DIMM is engineered specifically for HPE servers, removing the guesswork of compatibility and giving you confidence that the memory will perform exactly as required.

Benefits of HPE DIMM
  • Reliability: ECC correction prevents data corruption, keeping your systems stable.
  • Performance: 2666 MHz speed accelerates application response times.
  • Compatibility: Tested for HPE Gen9/Gen10 platforms, ensuring a perfect fit.
  • Scalability: Dual-rank design allows you to expand memory capacity further.
  • Efficiency: DDR4 technology reduces power usage while maintaining high throughput.

Usages of a 2666 MHz DIMM

The 2666 MHz DIMM is ideal for virtualised environments, cloud computing nodes, large database servers and any HPE ProLiant, Apollo, Synergy or Blade system that demands high-capacity, error-correcting memory. It helps you maintain uptime and performance across a wide range of enterprise workloads.
