The Samsung M393B5270DH0-CH9 is a server memory module that offers 4 GB of DDR3 capacity and a data rate of 1333 Mbps. It is built for administrators who value steady performance and long-term reliability in rack, tower, and blade systems.

This module follows the Registered DIMM design, placing a small register between the memory controller and the DRAM chips. By buffering clock, command, and control signals, the register helps maintain signal integrity when a motherboard is populated with two DIMMs per channel. The result is smoother operation during virtualization, file-serving, or database workloads where consistent memory timing matters.

An 8-bit parity chip provides ECC support, automatically detecting and correcting single-bit errors to reduce the risk of crashes or data loss. The internal layout uses a 1R x 4 organization with a (512M x 4) x 18 composition, meeting JEDEC requirements for enterprise-grade stability.

Flexible power options allow the module to run at either 1.5 V or 1.35 V. Administrators can choose the lower-voltage setting to save power and reduce thermal output in densely packed racks, or stay at the standard voltage when mixed-voltage modules are present.

The 240-pin interface connects to any motherboard that supports DDR3 Registered DIMMs, making installation straightforward in new builds or memory upgrades. Whether you are expanding a virtualization host, refreshing a storage server, or assembling a home-lab cluster, this module delivers dependable performance with minimal fuss.

Highlights:
  • 4 GB capacity, DDR3 Registered DIMM
  • Up to 1333 Mbps data rate for steady server throughput
  • Operates at 1.5 V or 1.35 V to balance performance and power use
  • Error-correcting code with 8-bit parity for higher data integrity
  • 240-pin interface for standard DDR3 server motherboards
  • 1R x 4 rank and organization with (512M x 4) x 18 layout
  • Register buffers clock, command, and control signals to support two DIMMs per channel installations
