H8QI6/i-F Serverboard User’s Manual
1-3 Chipset Overview
The H8QI6/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 Processor
The AMD SR5690/SP5100 are each a single-chip, high-performance HyperTrans- port peripheral controller. It includes a 46-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 six-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 H8QI6/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 volt- age 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.
