1-3 Chipset Overview
The H8DMT+/H8DMT-INF+ motherboard is based on the nVidia MCP55-V Pro
chipset. The nVidia MCP55 Pro functions as Media and Communications Proces-
sor (MCP). Controllers for the system memory are integrated directly into AMD
Opteron processors.
MCP55-V Pro Media and Communications Processor
The MCP55-V Pro is a single-chip, high-performance HyperTransport peripheral
controller. It includes a 28-lane PCI Express interface, an AMD Opteron 16-bit Hyper
Transport interface link, a four-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 effi cient use of memory
in multi-processor systems. The end result is a signifi cant increase in bandwidth
within the chipset.
