1-4 Chipset Overview

T h e H 8 D C T- H L N 4 F / H I B Q F s e r v e r b o a r d i s b a s e d o n t h e A M D AMD SR5670 or SR5690 and SP5100 chipset. This chipset functions as a Media and Communications Processor (MCP). Controllers for the system memory are integrated directly into AMD Opteron processors.

AMD AMD SR5670 or SR5690 and SP5100 Chipset

The AMD AMD SR5670 or SR5690 and SP5100 chispsets are each a single-chip, high-performance HyperTransport peripheral controller. They include a 30 or 42- lane PCI Express interface, an AMD Opteron 16-bit Hyper Transport interface link,

asix-port Serial ATA interface and a four-port USB 2.0 interface. This hub connects directly to the CPU.

HyperTransport Technology

HyperTransport technology is a high-speed, low latency point to point link that was designed to increase the communication speed by a factor of up to 48x between integrated circuits. This is done partly by reducing the number of buses in the chipset to reduce bottlenecks and by enabling a more efficient use of memory in multi-processor systems. The end result is a significant increase in bandwidth within the chipset.

1-5 PC Health Monitoring

This section describes the PC health monitoring features of the H8DCT-HLN4F/HIBQF serverboard. The serverboard has an onboard System Hardware Monitor chip that supports PC health monitoring.

Onboard Voltage Monitors

The onboard voltage monitor will continuously scan crucial voltage levels. Once a voltage becomes unstable, it will give a warning or send an error message to the screen. Users can adjust the voltage thresholds to define the sensitivity of the voltage monitor. Real time readings of these voltage levels are all displayed in BIOS.

Fan Status Monitor with Firmware/Software Speed Control

The PC health monitor can check the RPM status of the cooling fans. The onboard fans are controlled by thermal management via BIOS.
