Overview
The AMD-8131BLCFW is a server chipset component manufactured by Advanced Micro Devices. It functions as the northbridge within the AMD 8000 series architecture, designed to support dual AMD Opteron processors via Socket 940. The chipset facilitates HyperTransport technology with an 800MHz bus frequency and manages system memory access for registered ECC DDR modules operating at frequencies up to 400MHz. It provides connectivity through multiple PCI-X slots and integrates with the AMD 8111 southbridge for peripheral management.
Feature Summary
- Supports dual AMD Opteron processors on the Socket 940 platform
- Enables high-speed interconnection via HyperTransport technology
- Manages registered ECC DDR memory configurations
Applications
- Dual-processor server systems
- Enterprise computing platforms requiring registered ECC memory
- Infrastructure utilizing PCI-X expansion architectures
Procurement Notes
Verify the specific suffix 'BLCFW' against official AMD documentation to confirm exact stepping or revision differences. Ensure compatibility with the corresponding AMD 8111 southbridge for complete chipset functionality. Confirm socket requirements match the target motherboard design before procurement.
Selection Notes
Select this component for legacy server designs requiring the AMD 8131 northbridge. It is suitable for systems needing dual Opteron support and PCI-X expansion capabilities. Verify that the existing infrastructure supports the required DDR memory speeds and HyperTransport bus specifications.
Part Context
This part belongs to the AMD 8000 series chipset family, specifically serving as the northbridge solution for early dual-core Opteron platforms. It was widely used in enterprise servers during the transition to multi-core processing, providing essential memory and I/O control functions alongside the AMD 8111 southbridge.
Replacement Considerations
No public confirmed substitute part numbers are available for direct replacement. Modern alternatives require significant architectural changes due to differences in socket types, memory standards, and bus technologies.
