1.1.2. VIA VX11H MSPIII Chipset

The VIA VX11H is the fourth generation, highly integrated Media System

Processor which provides high quality digital video streaming and high

definition video playback. It features the VIA Chrome™ 640 DX11 2D/3D

graphics and video processor, High Definition video decoder and supports

DDR3 1333 controller and USB 3.0 interface.

The VIA VX11H offers superb-graphics performance, immersive visual

experience, and supports DirectX 11.0 that allows realistic 3D rendering and

increased visual acuity. It is also based on a highly sophisticated power

efficient architecture that enables such rich integration into a compact package.

1.1.3. Modular Expansion Options

The VIA EPIA-M920 ensures long-term usability with its support for industry

standard expansion options. Its support for legacy PCI expansion cards helps

to smooth and reduce the costs of transitioning to newer expansion

technologies. The VIA EPIA-M920 enables companies to slowly roll out

upgrades as necessary instead of having to replace everything all at once. This

ensures that companies using the EPIA-M920 obtain the maximum benefits

from its past investments in PCI expansion cards.

The VIA EPIA-M920 also includes a 4-Lane PCI Express 2.0 expansion slot that

provides protection against obsolescence.

Note:

As the operating temperature provided in the specifications is a result of the test performed in VIA’s

chamber, a number of variables can influence this result. Please note that the working temperature may

vary depending on the actual situation and environment. It is highly suggested to execute a solid

testing and take all the variables into consideration when building the system. Please ensure that the

system runs well under the operating temperature in terms of application.
