Samsung 2GB DDR3 1333 Mbps Server Memory Module

The Samsung M393B5673GB0-CH9 is a 2 GB DDR3 Registered DIMM designed for servers that need dependable performance and error-correcting capability. Running at a data rate of 1333 Mbps, it delivers the bandwidth required for day-to-day virtualization tasks, database operations, and other memory-intensive workloads.

This module follows a 2 R x 8 layout built from eighteen 128 M x 8 memory chips. Because it is a registered DIMM with integrated parity, it reduces electrical load on the memory controller and actively checks for and corrects single-bit errors. The result is improved signal integrity and better overall stability, especially when multiple DIMMs are installed in the same channel.

Dual-voltage support allows operation at either 1.5 V or 1.35 V. Running at the lower voltage can cut power consumption in dense rack environments where dozens of modules may be active around the clock. The 240-pin form factor fits any server motherboard that accepts DDR3 RDIMM modules, and the part works in systems that use x4 or x8 memory organizations, making it a straightforward replacement or capacity upgrade.

IT administrators looking to add a modest amount of memory to a file server, a small business virtualization host, or a lab test bed will find this module easy to integrate. Its registered ECC design is particularly helpful in servers that operate with two DIMMs per channel, where unbuffered memory can struggle to maintain signal quality.
