Introducing the Motherboard

Feature

Processor

The motherboard uses a 754-pin socket that carries the following features:

• Supports AMD K8 processors with HyperTransport Technology

The VIA K8M800 Northbridge (NB) and VIA VT8237R Southbridge (SB) chipset is based

on an innovative and scalable architecture with proven reliability and performance.

Chipset

HyperTransport Technology is a point-to-point link between two devices, it enables

integrated circuits to exchange information at much higher speeds than currently avail-

able interconnect technologies.
