Samsung 8GB DDR3 1066 Mbps Server Memory Module

The Samsung M393B1K73CH0-CF8 is an 8 GB memory module that follows the DDR3 standard, uses the Registered DIMM format, and is built for servers that demand consistent uptime. With a data rate of 1066 Mbps, it delivers the bandwidth required for tasks such as virtual machine hosting, web applications, and database services without placing added strain on the memory controller.

This module runs at either 1.5 V or a lower-power 1.35 V setting, giving administrators flexibility when balancing performance with energy efficiency across large racks. Integrated ECC with an additional 8-bit parity layer automatically corrects single-bit errors and detects multi-bit faults, which helps prevent system crashes and data corruption in mission-critical workloads.

The register on the module shifts clock, command, and control signals away from the memory controller, reducing electrical loading and improving overall signal integrity. A 4R × 8 rank structure and the (256 M × 8) × 36 chip layout allow the module to operate reliably in motherboards that support x4 or x8 configurations, including systems that populate two DIMMs per channel. The 240-pin design follows common server slot specifications, making installation straightforward for IT staff upgrading or expanding capacity in existing platforms.

Whether you manage a small business server, a high-density blade enclosure, or a lab environment used for development and testing, the M393B1K73CH0-CF8 provides a stable, energy-aware way to boost memory capacity and maintain data integrity over long operating cycles.
