H8QG6/i+-F Serverboard User’s Manual
1-3 Chipset Overview
The H8QG6/i+-F serverboard is based on the AMD SR5690/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 SR5690/SP5100 Chipsets
The AMD SR5690/SP5100 are each a single-chip, high-performance HyperTransport peripheral controller. It includes a 42 or 30-lane PCI Express interface, an AMD Opteron 16-bit Hyper Transport interface link, a six-port Serial ATA interface, a dual- port Gb Ethernet interface and a seven-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.
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the H8QG6/i+-F 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.
