Product Condition: New
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.
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.
Ideal for a range of professional environments, this module can be deployed in:
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.

We are retiring PICOPC Products MNHO-073, MNHO-048 and MNHO-043 and they have reached EOL (End Of Life) as we are introducing new products with better technology. We would recommend you to look into MNHO-095. For Untangle, pfSense, OPNsense, Windows 11, Proxmox VE etc. we recommend MNHO-095 whereas for Sophos, Kerio Control and Endian, we would recommend MNHO-069. (A complete list of supported OS can be found in each product's listing)
