Samsung 64GB DDR4 3200 MHz SDRAM Memory Module

The Samsung M393A8G40AB2-CWE is a memory module that offers 64 GB of capacity on a DDR4 interface running at 3200 MHz. It is a registered DIMM, so a dedicated register buffers the clock, command, and control signals before they reach the DRAM chips, keeping large memory configurations stable on server and workstation motherboards.

Error-correcting code is built in with 8-bit parity, allowing the module to detect and correct common memory faults without interrupting workloads. Engineers and IT administrators who manage virtual machines, in-memory databases, or high-performance computing clusters can count on this feature to protect data integrity around the clock.

The module follows the JEDEC DDR4 specification and operates at just 1.2 volts, which helps conserve power and reduce heat inside dense rack systems. A dual-rank layout based on a 2Rx4 organization balances density and throughput, while 288 pins ensure straightforward compatibility with boards that accept DDR4 registered DIMMs.

Whether you are expanding a virtualization host, refreshing a file server, or building a new analytics node, this Samsung module delivers the capacity, speed, and reliability needed for enterprise workloads.
