SAMSUNG M386AAG40AM3-CWE 128GB 3200MT/s LRDIMM accessory

SKU CH-VBT6-2SFXV MPN M386AAG40AM3-CWE

A 128 GB load-reduced DIMM running at 3200 MT/s for high-density server memory

  • High-capacity 128GB module supports demanding server workloads
  • Load-reduced design lowers electrical load on the memory bus
  • 3200MT/s data rate delivers fast throughput for intensive tasks
  • 4DRx4 organisation maximises density within a single DIMM slot
  • Samsung engineering ensures reliable enterprise-grade performance

128GB 3200MT/s LRDIMM for Servers

This 128GB load-reduced DIMM operates at 3200MT/s and uses a 4DRx4 organisation. It is built for enterprise servers and workstations that require very high memory density per slot. The module is sold individually and is brand new.

DIMM Form Factor with 4DRx4 Layout

The standard DIMM form factor fits server memory slots that accept load-reduced modules. The 4DRx4 configuration reduces electrical load on the memory bus, allowing larger total system memory without signal degradation. No special mounting hardware is required beyond a compatible DIMM socket.

128GB Capacity per Module

Each module provides 128GB of capacity, which is the decisive figure for planners calculating maximum memory per socket. Systems that do not support load-reduced DIMMs or this density cannot use the part.

Questions about this item

What speed does the 3200MT/s rating actually deliver on a compatible platform?

The module runs at 3200MT/s when the memory controller supports that data rate; otherwise it operates at the highest speed the platform allows.

What physical space does the 128GB LRDIMM need inside the chassis?

It uses a standard DIMM form factor, so it requires a full-height DIMM slot and enough vertical clearance for a load-reduced module.

How is the M386AAG40AM3-CWE installed, and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, then verify the module is fully seated by checking both ends are level.
