Samsung 4GB DDR3 1333 Mbps Server Memory Module

Overview

The Samsung M393B5270DH0-CH9 is a 4 GB DDR3 Registered DIMM server memory module designed to provide reliable and consistent performance in rack, tower, and blade server systems. With a data rate of 1333 Mbps, it supports demanding workloads such as virtualization, file serving, and database management by maintaining stable memory timing and signal integrity. Its ECC capability helps prevent data corruption, making it a solid choice for enterprise environments that require dependable memory operation.

Key features

• Registered DIMM design buffers clock, command, and control signals to ensure stable operation when using two DIMMs per channel.
• ECC with 8-bit parity automatically detects and corrects single-bit errors to reduce the risk of system crashes and data loss.
• Dual voltage operation at 1.5 V or 1.35 V allows for power savings and lower heat output in dense server configurations.
• 1R x 4 rank and (512M x 4) x 18 internal layout meets JEDEC standards for enterprise-grade memory stability.
• 240-pin interface ensures compatibility with standard DDR3 Registered DIMM server motherboards for easy installation and upgrades.
