Running out of memory when your server or workstation tries to handle multiple tasks can cause slowdowns and crashes. The Samsung M391A2K43BB1-CTD 16GB/2666MHz Ram Module adds reliable, high-capacity DDR4 memory, giving your system the headroom it needs to stay responsive and stable during demanding workloads.

Upgrade your system with the Samsung M391A2K43BB1-CTD 16GB/2666MHz Ram Module for smoother performance

Modern servers and high-end PCs often struggle with data-intensive applications, leading to bottlenecks that affect productivity. Insufficient RAM means the processor must constantly swap data to slower storage, increasing latency. This module provides a solid 16 GB of ECC-protected DDR4 memory at 2666 MHz, eliminating those bottlenecks and ensuring your system can handle heavy multitasking without error-induced interruptions.

Usages of Samsung M391A2K43BB1-CTD 16GB/2666MHz Ram Module

Ideal for a range of professional environments, this module can be deployed in:

  • Enterprise servers that require error-checking memory for critical data integrity.
  • Workstations used for 3D modelling, video editing, or scientific simulations.
  • Database servers handling large transaction volumes.
  • Virtualisation hosts running multiple virtual machines simultaneously.
  • High-performance desktop PCs that need extra memory for gaming or content creation.

 

Key Features of Samsung M391A2K43BB1-CTD 16GB/2666MHz Ram Module
  • Form Factor: DIMM 288-pin. Fits standard desktop and server motherboards.
  • Data Integrity Check: ECC. Detects and corrects single-bit errors to protect data.
  • Latency Timings: CL19 (19-19-19). Provides a balanced response time for server workloads.
  • Technology: DDR4 SDRAM. Offers higher transfer rates and lower power use than previous generations.
  • Speed: 2666 MHz (PC4-21300). Delivers fast data throughput for demanding applications.
  • Capacity: 16 GB. Supplies ample memory for multitasking and large datasets.
  • Features: Dual rank, On-Die Termination (ODT), sixteen banks, unbuffered. Improves signal stability and performance.
  • Registered or Buffered: Unbuffered. Suitable for standard server and workstation configurations.
  • CAS Latency: 19. Indicates the number of clock cycles needed to access data.
  • Colour: Black. Blends discreetly with most system interiors.

 

Benefits of Samsung M391A2K43BB1-CTD 16GB/2666MHz Ram Module

You gain a noticeable boost in system responsiveness, allowing applications to load faster and run smoother. The ECC protection safeguards critical data, reducing the risk of corruption during intensive processing. Its 16 GB capacity gives you the headroom to run multiple programs or virtual machines without slowdown. The 2666 MHz speed ensures high-bandwidth data transfer, keeping your CPU fed with information quickly. Finally, the unbuffered design simplifies installation while maintaining reliable performance in both servers and workstations.
