Samsung 64GB DDR4 2666 Mbps Server Memory Module

The Samsung M386A8K40CM2-CTD is a 64GB DDR4 server memory module that boosts system capacity while keeping power draw to a minimum. Operating at 2666 Mbps on just 1.2 V, it adds bandwidth without adding much heat, a benefit for densely packed racks and energy-conscious data centers.

This module relies on load reduced DIMM architecture. A dedicated register manages clock, command, and control signals, and a separate data buffer handles the data lines. Offloading these tasks eases the electrical load on the memory controller, so you can populate as many as three modules per channel without sacrificing signal integrity or stability.

The 4R x 4 rank layout, built with a (DDP4G x 4) x 36 component configuration, delivers the density needed for intensive workloads. With 288 pins, the module slots directly into any server motherboard that supports DDR4 LRDIMMs at 2666 speed. From virtualization hosts and in-memory databases to real-time analytics nodes, it provides the headroom required to keep applications responsive and throughput high.

Highlights:

• 64GB DDR4 load reduced DIMM module
• 2666 Mbps data transfer rate
• 1.2 V operating voltage
• 4R x 4 rank organization with (DDP4G x 4) x 36 layout
• 288-pin form factor for DDR4 server slots
• Supports up to three LRDIMMs per channel in compatible systems
