AMD-8131BLCT

Overview

The AMD-8131BLCT is a North Bridge chipset component manufactured by Advanced Micro Devices, designed for the AMD Opteron platform. It utilizes the Socket 940 interface and supports HyperTransport technology with an 800MHz bus frequency. The chipset facilitates dual-processor configurations and manages system memory access for registered ECC DDR modules operating at frequencies up to 400MHz. It provides expansion capabilities through multiple PCI-X slots, serving as a critical interconnect between the CPU, memory subsystem, and peripheral devices in server architectures.

Feature Summary

• Supports dual AMD Opteron processors via Socket 940 interface
• Integrates HyperTransport technology for high-speed CPU-to-chipset communication
• Manages registered ECC DDR memory for data integrity
• Provides dedicated PCI-X expansion slots for peripheral connectivity

Applications

• Dual-processor server platforms requiring high reliability
• Enterprise computing systems utilizing registered ECC memory
• Infrastructure hardware relying on PCI-X expansion standards

Procurement Notes

Verify the specific suffix 'BLCT' against official AMD documentation to confirm package type and temperature grade. Ensure compatibility with the corresponding South Bridge, typically the AMD 8111, for complete chipset functionality. Confirm that the source document explicitly lists this part number as a standalone North Bridge component rather than a bundled set.

Selection Notes

Select this component only for designs requiring the AMD 8131 North Bridge architecture. Verify support for the target processor generation, specifically Socket 940 Opterons. Ensure the motherboard design accommodates the required power delivery and thermal specifications for the chipset. Confirm availability of the companion South Bridge chip for full system operation.

Part Context

The AMD-8131 serves as the North Bridge in the AMD K8 architecture, working in tandem with the AMD 8111 South Bridge. This pairing enables high-bandwidth communication for Opteron processors. The BLCT suffix likely denotes a specific manufacturing lot, package variant, or temperature range defined by AMD for industrial or commercial applications within the server chipset family.

Replacement Considerations

Direct replacements are limited due to the proprietary nature of the AMD 8131/8111 chipset pair. No public substitute part numbers are confirmed for this specific North Bridge component. System redesign may be necessary if sourcing this legacy part proves difficult.
