VIA EPIA-P830 overvie
The VIA EPIA-P830 Pico-ITX Mainboard is a compact nati e x86 mainboard optimized for multimedia
applications. The mainboard is based on the VIA VX900 Unified Digital Media IGP chipset featuring the VIA
Chrome9™ HC with 2D/3D graphics and ideo accelerators for rich digital media performance.
The VIA EPIA-P830 includes a powerful, secure, and efficient VIA Nano™ processor. The VIA Nano processor
includes the VIA Padlock Security Engine, VIA CoolStream™ Architecture, VIA StepAhead™ Technology Suite,
and VIA TwinTurbo™ technology.
The VIA EPIA-P830 includes one 1066/800 MHz DDR3 SODIMM slot that supports up to 4 GB. The VIA EPIA-
P830 pro ides support for high fidelity audio with its included VIA VT1708S High Definition Audio codec. In
addition it supports two SATA 3Gb/s storage de ices.
The VIA EPIA-P830 is fully compatible with Microsoft
®
and Linux operating systems.
