🛠️ Key Features & Installation Requirements

  • ECC workstation/server-grade RDRAM

  • Install in matched pairs

  • Any empty RIMM slots require continuity RIMMs (C‑RIMMs)

  • Requires ECC-capable motherboard and BIOS

  • Compatible with Intel 820/840 chipset platforms

🖥️ Compatible PC Models

The kit supports ECC-enabled RDRAM systems, especially workstation-class desktops and servers.

✅ OEM Systems

HP / Compaq Desktops/Workstations (PC800 RDRAM ECC builds):

  • Compaq Presario 5000/7000 series Desktop models (e.g., 5000XX, 7000T, 7100, 7112, 7120, 7RC series)

  • HP Vectra VL800/VL810 (workstation editions)

  • HP Kayak XA/XU/XM ECC workstation builds

Dell:

  • Precision Workstation 220/420 with PC800 ECC RDRAM (optional configurations)

IBM:

  • ECC-capable IntelliStation M Pro/Z Pro or NetVista ECC RDRAM systems

✅ Custom/Server Motherboards

  • Intel VC820, D820LP/D820GB (Socket 370/423, ECC RDRAM support)

  • Intel OR840 (ECC dual-channel RDRAM)

  • Supermicro P3TDE / P3TDE6 (dual CPU ECC boards)

  • ASUS CUR-DLS (Slot-1 ECC workstation board)

  • Tyan Thunder 2500 S1867 (ECC-supported server/workstation)

❌ Not Compatible With

  • Consumer desktops lacking ECC BIOS (e.g., standard Dell Dimension, HP Pavilion without ECC)

  • DDR/SDR-based chipsets (Intel 845, 850, etc.) or PC800/PC1066 RDRAM boards requiring non-ECC RDRAM

  • Systems without BIOS ECC support

⚠️ Installation Notes

  • Must be installed in matched pairs

  • C‑RIMMs are required to close open RIMM slots

  • ECC must be enabled in BIOS

  • Ensure adequate airflow — RDRAM runs hot and includes heat spreaders
