Samsung 8GB PC3L-12800R DDR3-1600 1RX4 ECC Memory Module

The Samsung M393B1G70QH0-YK0 is an 8 GB memory module designed for servers that depend on DDR3 technology with Registered ECC support. It installs in a standard 240-pin RDIMM slot and moves data at up to 1600 MT/s, giving virtualization hosts, database engines, and other resource-intensive workloads the bandwidth they need.

This module uses a single-rank 1Rx4 layout built from x4 components. A dedicated register sits between the memory controller and the DRAM chips to steady clock and control signals, while an 8-bit parity scheme continuously checks and corrects errors before they reach the operating system. The result is stable performance, fewer crashes, and greater peace of mind when uptime is critical.

Flexible voltage support lets the DIMM run at the standard 1.5 V or switch to 1.35 V in energy-optimized platforms, helping data centers trim power draw and manage thermal loads. Administrators who populate boards with two DIMMs per channel will appreciate that the module is validated for such configurations and works with both x4 and x8 organizations, making mixed installations simpler.

Whether you are expanding a rack-mounted server that runs multiple virtual machines, refreshing a high-traffic web service, or building a lab environment for development and testing, this Samsung RDIMM offers a straightforward path to dependable memory capacity. Installation follows the same process as any other DIMM: power down the system, insert the module into a compatible slot, and power back up to let the firmware recognize the added capacity.

Highlights:

• 8 GB capacity with a data rate of 1600 MT/s for responsive server performance
• Registered design stabilizes clock and control signals
• Error-correcting code with 8-bit parity protects against data corruption
• Single-rank 1Rx4 layout based on x4 components
• Operates at either 1.5 V or 1.35 V, allowing standard or low-power operation
• 240-pin RDIMM form factor that supports dual-DIMM-per-channel server boards
