1-3 Chipset Overview
The H8DGU(-F) serverboard is based on the AMD SR5670/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 SR5670/SP5100 Processor
The AMD SR5670/SP5100 are each a single-chip, high-performance HyperTrans-
port peripheral controller. It includes a 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 con-
nects 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 effi cient use of memory
in multi-processor systems. The end result is a signifi cant increase in bandwidth
within the chipset.
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the H8DGU(-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 defi ne 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.
