Server RDIMM Samsung DDR4 128GB 3200MHz Registered 288-pin 1.2V

The Samsung M393AAG40M32-CAE is a 128 GB DDR4 memory module operating at 3200 MHz in a 288-pin DIMM form factor. Designed for PC and server environments, this module offers a single-module 128 GB capacity and a 1.2 V operating voltage to support heavy multitasking and memory‑intensive workloads while maintaining energy efficiency.

Advantages

This Samsung DDR4 128GB 3200MHz module provides a high-capacity single-module solution that reduces the need for multiple modules and supports faster data transfer at 3200 MHz. The 1.2 V power requirement helps lower overall system power consumption, and the 288-pin DIMM design ensures compatibility with standard desktop and server DDR4 memory slots.

Suitable for

• Virtualization hosts and server workloads
• Professional workstations for video editing, 3D rendering and CAD
• High-performance desktop systems and gaming PCs requiring large memory pools
• Data analysis, databases and in-memory computing tasks

Key specifications

• Capacity: 128 GB
• Type: DDR4
• Clock speed: 3200 MHz
• Form factor: 288-pin DIMM
• Voltage: 1.2 V
• Manufacturer part number (MPN): M393AAG40M32-CAE

How to use

Install the module into an available DDR4 288-pin DIMM slot on a compatible motherboard or server board while the system is powered off and unplugged. Align the notch on the module with the slot key, press firmly until the retention clips engage, and then power on the system. Verify that the system BIOS/UEFI detects the full 128 GB capacity and that memory settings such as speed and voltage are set according to motherboard recommendations.

Recommendations

Use this module in systems that officially support DDR4 3200 MHz and a single-module 128 GB configuration; consult the motherboard or server documentation for supported memory capacities and population rules. For optimal stability in multi-module configurations, ensure matched modules and consider BIOS/firmware updates recommended by the system vendor.
