AMD-8131BLCW

Overview

The AMD-8131BLCW is a North Bridge chipset component manufactured by Advanced Micro Devices, designed for high-performance server and workstation platforms. It serves as the central hub connecting the processor to system memory and expansion buses. The chipset supports dual AMD Opteron processors via the HyperTransport bus operating at 800MHz. It manages data flow between the CPU sockets and DDR memory modules, supporting capacities up to 16GB across two CPUs with ECC and registered memory types. The architecture integrates PCI-X controller capabilities for high-speed peripheral connectivity.

Feature Summary

• Supports dual AMD Opteron processors utilizing the 800MHz HyperTransport interconnect technology
• Manages system memory interface for DDR200/266/333/400 specifications with error correction support
• Provides integrated PCI-X bus controllers for high-bandwidth peripheral expansion slots

Applications

• Dual-processor server motherboards requiring high memory bandwidth
• Workstation platforms utilizing AMD Opteron architecture
• Enterprise systems needing PCI-X expansion capabilities

Procurement Notes

Verify the specific suffix 'BLCW' against official AMD documentation to confirm package type and temperature grade. Ensure compatibility with the corresponding AMD-8111 South Bridge for complete chipset functionality. Confirm that the source provides genuine AMD manufacturing data rather than third-party generic listings.

Selection Notes

Select this component for designs requiring the AMD 8131 North Bridge functionality paired with Socket 940 processors. Verify that the motherboard layout supports the required pin count and thermal dissipation for the BLCW package variant. Ensure the design utilizes compatible DDR memory modules adhering to the supported speed grades.

Part Context

This part belongs to the AMD 8000 Series Chipset family, specifically the North Bridge component. It is typically paired with the AMD-8111 South Bridge to form a complete platform solution for dual-socket AMD Opteron systems released in the mid-2000s era.

Replacement Considerations
