  • GENERAL SUPPORT
    Q: I don't know what hardware I have in my system. How can I find out?
    A: We recommend that you follow this guide.
    Q: I am very confused. I don't understand the basic terminology of computing. Can you help?
    A: We recommend that you read over this helpful guide.
    Q: There is more than one VIA storage driver choice. What is the difference between them?
    A: We recommend that you read over this guide.
    Q: How much RAM can I put on my motherboard? Which CPUs can I use?
    A: For VIA EPIA and VB motherboards, please select your board from this list to check the board specifications. For partner motherboards that feature a VIA chipset, VIA cannot advise you on the maximum RAM, HDD capacity, CPU type or any other compatibility/capability issues with your motherboard as it depends on how the motherboard manufacturer has implemented the chipset. Two motherboards based on the same chipset may have different limits. This information must be obtained from the motherboard manufacturer or the motherboard manual. For help identifying your motherboard and/or chipset, please read this article.

    DRIVERS
    Q: I use Microsoft Windows, but I don't know which driver I need.
    A:

    We recommend that you read this article on Microsoft Windows drivers before you start. If you are not sure what hardware you have in your system, please read this article. Once you understand what you need, go to the VIA driver portal and follow the instructions to download your drivers.

    If you are using Microsoft Windows 7, please refer to this section for additional driver information.

    Q: I know I have a VIA chipset. What drivers do I need to install?
    A:

    All VIA chipsets require the VIA Hyperion Pro drivers. From the driver downloads main page, select your operating system at Step 1, and Hyperion Pro (4in1) chipset drivers at Step 2. Download the latest version and save it to your hard drive. Unzip the zip folder and then double click on the .exe file to start the installation.

    You may also require other drivers. We recommend that you follow this guide to identify your system's hardware specifications and then visit either your motherboard manufacturer's website for further drivers, or return to the VIA driver portal for them.

    Q: Do I need to uninstall my current 4in1 drivers or Hyperion Pro drivers before installing new/updated ones?
    A: No. Simply download and install the drivers over the current ones.
    Q: Should I install the Hyperion Pro drivers or older VIA 4in1 drivers?
    A: It is not necessary to update VIA Hyperion or 4in1 drivers if your system is stable. The latest VIA Hyperion Pro drivers are suitable for any VIA chipset and all Microsoft Windows Operating Systems; however, it is recommended that VIA 4in1 drivers are used for legacy VIA chipsets. These legacy chipsets include: MVP#, Apollo Pro## series, KT1##, KN1##, KM1##, KT2##, KT333, KN2##, KM2##, P4X2##, P4X3##, P4M2##. If you have a legacy hybrid chipset (VIA southbridge and AMD northbridge) you should obtain drivers from the motherboard manufacturer and not from this web site. All other VIA chipsets should use the VIA Hyperion Pro drivers.
    Q: How can I tell what version VIA Hyperion Pro drivers I have installed?
    A: Open Start - Run and type in "regedit" (without the apostrophe marks). Double click HKEY_LOCAL_MACHINE then SOFTWARE and check the listing under VIA Technologies, Inc. The version of the chipset/platform driver you have installed will be listed next to PACKAGE_VERSION.
    Q: I use a legacy Microsoft Windows desktop operating system (i.e. Windows 95, Windows 98, Windows 98SE, Windows ME or Windows 2000) and have a problem with a VIA chipset, or integrated graphics driver, or a system with a VIA chipset. Where can I obtain support?
    A:

    Microsoft and VIA no longer provide official updates or support for these legacy operating systems. VIA chipset and graphics drivers released for use with these operating systems are available from our driver portal; however, VIA no longer supports these driver packages.

    For support, please check online discussion boards, such as the VIA support forums.


    BIOS
    Q: Where can I obtain a BIOS for my VIA EPIA, VB series or other embedded motherboard?
    A: From this menu, choose the form factor of the motherboard. Then choose Check board models, then click on the model number of your board. You will then find BIOS available for download under the Downloads tab.
    Q: Where can I obtain a BIOS for my motherboard? It has a VIA chipset.
    A: All BIOS need to be obtained from the motherboard manufacturer's website, not the chipset manufacturer's website. For example, if you have an MSI motherboard with a VIA chipset, you need to get your BIOS from MSI, not from VIA.
    Q: I have a legacy VIA branded motherboard, an EPIA board that is no longer in production, or a VIA P4 motherboard. Where can I get a BIOS?
    A: Legacy VIA branded motherboard information and downloads can be obtained here.

    AUDIO
    Q: Where can I find a driver for the VIA Tremor VT1723 audio chip?
    A:

    The VIA Tremor VT1723 audio chip is supported by the VIA Envy 24 Family driver. At the driver database, select your operating system, then "Audio" and then "VIA Vinyl Envy24 Controllers: MT/DT/GT/PT/HT-S".

    Please note however that we strongly recommend you to obtain the system-validated and certified audio drivers directly from your system manufacturer or motherboard manufacturer .

    Q: Where should I obtain the best driver for my VIA audio solution?
    A:

    The audio drivers provided on this website are general sound effect drivers with common functions. System manufacturers and motherboard vendors customize audio hardware and software and therefore, to ensure optimal sound quality and compatibility, we strongly recommend you to obtain the system-validated and certified audio drivers directly from your system manufacturer or motherboard manufacturer.

    If you use audio drivers provided on this website and you experience a difficulty, we recommend that you uninstall them and instead use the latest drivers supplied by your motherboard or system manufacturer.

    Q: I cannot find my audio driver on your website / I don't know which driver I need. How can I find out?
    A:

    You need to find out what audio solution you have. Even if you have a VIA chipset, that doesn't necessarily mean that you have a VIA audio solution, and it's not enough information to ascertain what audio driver your system requires.

    First, find out the make and model of your motherboard or system. If you don't know this, run a free program such as SiSoft Sandra Lite which will identify your hardware. Then, look up your motherboard or system on the Internet and check the specifications listed on the manufacturer's website – this will include the chip ID number of your audio solution.

    With that information, you will be able to find the driver you require from our driver portal. Please note, however, that we recommend that you use the drivers provided by your motherboard or system manufacturer, since they may be optimized for their hardware.

    Q: Where can I find drivers for my Envy24 or Envy24 HT sound card?
    A: VIA does not supply drivers for sound cards based on the VIA Envy24 or Envy24 HT audio controllers. Drivers for those sound cards must be obtained from the manufacturer of the sound card.
    Q: What is the VIA VT2020, VT2021 or VT1828S audio solution? Where can I get a driver for it and why is there no information on VIA's site about it?
    A: The VIA VT2020, VT2021 and VT1828S are VIA HD audio controllers that have, thus far, been sold exclusively to ASUS for their high-end motherboards. Drivers are available on ASUS's website as they develop the drivers specifically for the way they have implemented the chip on their boards.
    Q: Where can I obtain the latest VIA 74mu or VIA 68mu audio drivers?
    A: Since June 2002, VIA has provided one combination driver for non-HD VIA audio solutions. Prior to this there was a 74mu170a driver for VT8233/VT8233A/VT8233C and the 68MU220b driver for VT686A, 686B & VT8321. The "combo" driver combined those two drivers into the one package and added support for the (at the time) new VT8235 southbridge. Further improvements have been made in subsequent releases, including adding support for more codecs and the driver package is now called Vinyl_AudioCodec.

    VIDEO/GRAPHICS
    Q: Where can I get a driver for my VIA chipset to support a widescreen monitor/resolution?
    A: The availability of a driver to support widescreen depends on what the chipset supports and whether or not the manufacturer of the motherboard featuring the VIA integrated chipset has requested the driver. All P4 and K8 chipsets do not support widescreen. This includes the following chipsets: PM880, PT800, PM800, P4X533, P4X400, P4X333, P4X266A, P4X266E, P4X266, P4M266 K8T900, K8T890, K8M890, K8T800 Pro, K8T800, K8M800. Older legacy chipsets supporting CPUs such as the Intel Pentium III and AMD Athlon and Duron processors, also do not support widescreen. The CN700, CX700 and CN896 chipsets are capable of supporting widescreen. To support widescreen the system BIOS must support it as well as the driver. You should obtain your latest BIOS and driver from the motherboard manufacturer and if widescreen is not supported, ask the manufacturer to update the BIOS and driver to support widescreen. The VX800, VX855 and later chipsets support widescreen as a standard rule, so all drivers for those chips on this website and on the motherboard manufacturer's websites will include this support.
    Q: I have an old S3 Graphics video card (like ViRGE, Savage or Tri3D). Where can I get the drivers?
    A: From S3 Graphic's software archive.
    Q: I cannot run a game I want to run. I have an integrated Chrome® 2D/3D graphics controller.
    A: Some games require a 100% Directx9.0(b) compatible 3D graphics accelerator, such as (but not limited to) Zoo Tycoon 2, ROME: TOTAL WAR or Call of Duty. Please check the minimum specifications of the game. The Chrome® 2D/3D integrated graphics controller is not Directx9 compatible. To play a game requiring DirectX 9.0a or DirectX 9.0b, you can install a DirectX 9.0 compatible 3D accelerator (video card) and disable the integrated graphics in the BIOS. A guide explaining how to do this can be found here.
    Q: I need help to identify my integrated graphics solution.
    A: We recommend that you follow this guide. A list of VIA integrated graphics chip IDs and chipset series names can also be found here.
    Q: I use a legacy Microsoft Windows desktop operating system (i.e. Windows 95, Windows 98, Windows 98SE, Windows ME or Windows 2000) and have a problem with a VIA chipset, or integrated graphics driver, or a system with a VIA chipset. Where can I obtain support?
    A:

    Microsoft and VIA no longer provide official updates or support for these legacy operating systems. VIA chipset and graphics drivers released for use with these operating systems are available from our driver portal; however, VIA no longer supports these driver packages.

    For support, please check online discussion boards, such as the VIA support forums.


    USB
    Q: I am having trouble with USB.
    A: We recommend that you read over this general guide and further information for USB PCI cards can also be found in this guide.
