Introducing the Motherboard

Feature

Processor

K8T890-A uses a 939-pin socket that carries the following features:

• Supports AMD K8 processors with HyperTransport Technology

• Transfer rate of 2000/1600/1200/800/400 MT/s

The VIA K8T890 Northbridge (NB) and VIA VT8237 Southbridge (SB) chipset is based

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