Samsung 4GB DDR3 1333 Mbps Server Memory Module

The Samsung M393B5273CH0-YH9 is a server-grade memory module with 4 GB capacity that uses DDR3 technology and a Registered DIMM layout. Operating at 1333 Mbps, it boosts data throughput while the built-in register maintains clean clock, command, and control signals—an important factor when multiple modules share the same channel.

The module supports a 2R × 8 configuration and works with x4 or x8 organization, so it fits easily into dual-slot-per-channel server boards that require two ranks per DIMM. Integrated error-correcting code and an additional 8-bit parity field catch and correct common memory faults, helping administrators keep virtualization hosts, database servers, and analytics nodes running without surprise crashes.

A standard 240-pin interface makes installation straightforward in a wide range of Intel and AMD server platforms. The module runs at either 1.5 V or a lower 1.35 V setting, giving data centers and small business racks an easy way to balance performance with energy savings.

Whether you are expanding memory in a dense rack server, refreshing a high-performance workstation, or building a test environment for development, this Samsung module offers stable operation, fault tolerance, and a clear path to higher capacity without overhauling your existing infrastructure.
