Samsung 4GB DDR3 1600 Mbps Memory Module

The Samsung M393B5173QH0-YK0 is a memory module created for servers that cannot afford downtime. It supplies 4 GB of DDR3 capacity and transfers data at 1600 Mbps, giving virtualization hosts, database machines, and file servers enough headroom to keep multiple tasks flowing without bottlenecks.

This module uses a register that sits between the memory controller and the DRAM chips, so clock, command, and control signals stay organized even when the system is under sustained load. Integrated error correction with an extra 8-bit parity field catches and repairs data errors on the fly, a safeguard that helps preserve data integrity during long-running workloads.

Flexibility in power delivery lets the module operate at the standard 1.5 V or at 1.35 V for lower-power servers. A single-rank x8 organization paired with a 240-pin layout fits seamlessly into motherboards that accept registered DIMMs. When used in a two-DIMM-per-channel configuration, the module allows administrators to scale capacity without sacrificing stability.

IT managers who maintain rack-mount servers, small business owners running an on-premise ERP system, and home lab enthusiasts building a reliable learning environment will appreciate the balance this module strikes between performance, efficiency, and dependability.
