H8DI3+/I+(-F) Serverboard User’s Manual

The H8DI3+/I+(-F) Serverboard 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.

The AMD SR5690 and SP5100 are each single-chip, high-performance 

HyperTransport peripheral controllers for northbridge and southbridge functions, 

respectively. They both include 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. The AMD SR5690 connects 

directly to the CPUs.

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.

This section describes the PC health monitoring features of the H8DI3+/I+(-F) 

Serverboard. The serverboard has an onboard System Hardware Monitor chip that 

supports PC health monitoring.

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 

voltage monitor. Real time readings of these voltage levels are all displayed in 

BIOS.

The PC health monitor can check the RPM status of the cooling fans. The onboard 

fans are controlled by thermal management via BIOS.
