    • Memory for IBM Power5

    IBM Power5 Compatible Memory Upgrades

    Upgrade or expand memory in your IBM Power5 servers with compatible DDR2 DIMMs at Data Tech Computer. Our selection includes enterprise-grade DDR2 memory modules (typically 400–533 MHz) optimized for Power5 models such as Power 520 (9405/9406-520), Power 550 (9406-550), Power 570 (9406-570), and Power 595 (9119-595). These modules provide reliable capacity increases and bandwidth improvements to support legacy AIX, IBM i (up to 7.1), and Linux workloads, virtualization, databases, ERP systems, and long-term maintenance of older Power5 environments.

    Key Benefits for Power5 Memory

    • DDR2 technology – 400–533 MHz speeds for stable legacy performance
    • Capacities from 1 GB to 16 GB per DIMM (feature codes EMxx series and equivalents)
    • Sold in matched pairs or quads for optimal channel population and bandwidth
    • Full compatibility with POWER5 memory controllers
    • Supports moderate-density configurations (up to 192 GB in Power 570/595, less in 520/550)
    • ECC and advanced error correction for mission-critical stability
    • 60-day warranty on all Power5 memory modules
    • Ideal for refreshing legacy Power5 systems, increasing memory for existing IBM i/AIX workloads, or maintaining compliance environments
