These modules are compatible with Intel 820/840-based workstations that support ECC RDRAM. They were not intended for consumer desktops like Dell Dimension or Gateway systems that used non-ECC RAM.

✅ IBM Systems (with IBM FRU: 38L3096)

  • IBM IntelliStation M Pro 6849 / 6850

  • IBM IntelliStation Z Pro 6865

  • IBM NetVista 2800 Series (with ECC RDRAM option)

  • IBM 6868, 6889 series Workstation platforms

These models were built on Intel 820/840 chipsets and had ECC-capable BIOS/firmware.

  • Dell Dimension 8100, 8200, 8250 (non-ECC RDRAM only)

  • HP Pavilion or Compaq Presario consumer desktops

  • Intel 850/850E chipset boards (require PC800 RDRAM)

  • DDR/SDR systems (completely different memory type)

  • Any system without ECC RDRAM BIOS/firmware support

🧩 Installation Notes

  • Must be installed in matched pairs

  • Empty RIMM slots require C-RIMM (Continuity RIMM)

  • ECC RDRAM only works in systems with ECC enabled in firmware

  • Check for chipset compatibility (Intel 820 or 840) and ECC requirement
