The IBM 39M5811 is a memory module, most likely a DIMM (Dual In-line Memory Module), designed for use in IBM server and workstation systems. Memory modules serve as temporary storage for data and instructions that the processor needs to access quickly. The 39M5811 contributes to the overall performance of the system by providing the necessary memory capacity for applications and the operating system to run efficiently.

Applications

• IBM System x Servers
• IBM BladeCenter Servers
• IBM IntelliStation Workstations
• Server memory upgrades
• Virtualization environments
• Database servers

Features

• DDR2 or DDR3 memory technology (depending on the server generation)
• ECC (Error-Correcting Code) for data integrity
• Registered DIMM (RDIMM) for improved stability in high-density configurations
• Specific memory capacity (e.g., 1GB, 2GB, 4GB)
• Specific memory speed (e.g., 667MHz, 800MHz, 1066MHz)
• 240-pin DIMM connector

Benefits

• Improved system performance and responsiveness
• Increased memory capacity for running more applications simultaneously
• Enhanced data reliability and reduced risk of data corruption thanks to ECC
• Optimized server performance for demanding workloads
• Simplified memory upgrades and expansions
• Reduced downtime due to memory errors

Additional Details

The IBM 39M5811 is specifically designed and tested to ensure compatibility and reliability within IBM server environments. The ECC feature is critical for server applications, as it detects and corrects single-bit memory errors, preventing data corruption and system crashes. Registered DIMMs (RDIMMs) include a register between the DRAM chips and the memory controller, which improves signal integrity and allows for larger memory configurations, making them suitable for servers with high memory demands.

To ensure proper compatibility and performance, it is crucial to consult the IBM documentation or a memory compatibility guide for the specific server or workstation model. Mixing different types of memory modules can lead to reduced performance or system instability. Refer to the server's technical specifications for the maximum supported memory capacity and the recommended memory configuration.
