Samsung 32GB DDR4 2666 Mbps Memory Module

The Samsung M391A4G43MB1-CTD is a 32 GB DDR4 memory module that pushes data at 2666 Mbps, giving workstations and servers the breathing room they need for heavy multitasking, complex simulations, or large database queries. It slides into a standard 288-pin DIMM slot and runs at just 1.2 V, helping keep power draw and heat in check when systems are under load.

This module follows a 2R × 8 layout with eighteen x8 devices spread across two ranks, a structure that maintains signal integrity while offering generous capacity in a single stick. Built-in single-bit error correction detects and repairs the most common memory faults on the fly, an essential safeguard for financial analysis, scientific research, virtual machines, or any task where data accuracy cannot be compromised.

IT managers will appreciate the predictable performance curve when clustering these modules in multi-channel configurations, while content creators and developers gain the headroom to keep multiple resource-intensive applications open without a slowdown. Whether you are upgrading an existing server or outfitting a new workstation, this Samsung DIMM provides stable, ECC-protected memory that lets the processor focus on compute work instead of handling memory errors.
