    IBM Power5 Memory Upgrades - DDR1 & DDR2 DIMMs

    Upgrade or expand memory in your IBM Power5 servers with compatible DDR1 and DDR2 DIMMs at DataTechComputer.com. Our selection includes enterprise-grade modules 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 Features of IBM Power5 Memory

    • • DDR1 and DDR2 technology – 533 MHz speeds for stable legacy performance
    • • Capacities from 512 MB to 16 GB per kit (feature codes 44xx and 447x series)
    • • 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
