Samsung 32GB DDR3 4Rx4 PC3-14900L Memory Module

Overview

The Samsung M386B4G70BM0-CMA is a 32GB DDR3 Load Reduced DIMM designed specifically for server environments that require expanded memory capacity without compromising stability. Operating at 1866 Mbps, it supports demanding workloads such as virtual machines and large databases by delivering fast data transfer rates and efficient memory access. Its 4Rx4 rank structure and onboard buffering ensure reliable performance even under heavy multi-core processor loads.

Key features

• Load Reduced DIMM technology reduces electrical load on the memory bus, allowing up to three DIMMs per channel for higher memory density.
• Dual-voltage operation at 1.5 V or 1.35 V provides flexibility for power optimization and compatibility with mixed DIMM populations.
• Onboard register and data buffer maintain signal integrity, ensuring stable and error-free data transmission in enterprise server setups.
• Standard 240-pin form factor enables easy installation in compatible DDR3 server slots without requiring special adapters.
• 4Rx4 rank organization distributes memory across four ranks of x4 devices, improving data access efficiency during peak workloads.

Key specs

• Capacity: 32 GB
• Memory type: DDR3 Load Reduced DIMM (LRDIMM)
• Data rate: 1866 Mbps
• Voltage: 1.5 V / 1.35 V dual-voltage support
• Rank structure: 4Rx4
• Form factor: 240-pin DIMM

Compatibility and use cases

This memory module fits well in dual- or quad-socket server boards that support DDR3 LRDIMM technology, making it a strong choice for data centers aiming to maximize memory capacity per channel. It is particularly suited for virtualization hosts, database servers, and other enterprise applications that demand large memory pools and consistent uptime. Its ability to support multiple DIMMs per channel helps administrators fully populate server memory slots to meet growing workload requirements.
