Supported Video Cards

(Updated 2010.1.04)

To facilitate purchase of hardware compatible with Userful Multiplier™, specific video cards are listed below in three color coded categories Recommended, Will Likely Work and Known Incompatible.

Recommended

Cards listed below are known to work under most circumstances. While it is impossible to guarantee that these cards will work in all combinations with all motherboards, we recommend purchasing one of the card models listed below.

Userful supports and recommends the following low cost single chip, dual head chipsets, which are available as AGP, PCI or PCI-E cards from a variety of manufacturers:

• ATI
  • Radeon™ 7000
  • Radeon™ 7500
  • Radeon™ 9000
  • Radeon™ 9200
  • Radeon™ 9250
  • Radeon™ X300
  • Radeon™ X550
  • Radeon™ X 1000 series (Requires Userful Multiplier 325 or v.3.7 and newer, available for beta download )
  • Radeon™ HD 2000 series (Requires Userful Multiplier 325 or v.3.7 and newer, available for beta download )
  • Radeon™ HD 3000 series (Requires Userful Multiplier 325 or v.3.7 and newer, available for beta download )
• NVIDIA nVidia Proprietary Drivers Required
  • GeForce FX 4400
  • GeForce FX 5200
  • GeForce 6600GT
  • GeForce 7200/7300GS
  • GeForce 7600GS
  • GeForce 8000 series (Requires Userful Multiplier 325 or v.3.7 and newer, available for download )
  • Geforce 9000 series (Requires Userful Multiplier 325 or v.3.7 and newer, available for download )
  • Quadro FX 500
  • Quadro FX 600
  • Quadro NVS 280
  • Quadro NVS 285
  • Quadro NVS 400
  • Quadro NVS 440
  • GeForce4 MX 440
  • GeForce2 MX/MX400
• Matrox Matrox Proprietary Drivers Required
  • G400 Series
  • G450 Series
  • G550 Series

Guidelines:

• Mixing multiple brands of video cards can produce unexpected problems.
• When installing Ubuntu, please use NVIDIA driver version 173 for older cards such as GE5200. Version 180 will work with Series 7 and higher.
• Installing PCI-E card will disable on-board video output by default.
• Older NVIDIA Cards: NVIDIA has a Unified driver that supports the majority of their popular and modern GPUs. They also have two legacy drivers for their older legacy GPUs. Since only one driver can be used simultaneously per system, combining older NVIDIA GPU chipsets in the same system with recent ones can cause some of the cards to not function. If you are mixing older NVIDIA cards and are uncertain whether this will be a problem here is a list of which models use the Unified and Legacy (96.43.xx and 71.86.xx) Drivers for reference. (This is not a problem with ATI cards)
• DVI Outputs: Userful Multiplier version 320 or less only supports automated configuration of VGA and DVI-convert-to-VGA outputs, cards with DVI ONLY (cards incompatible with DVI to VGA adapters) will most likely not have any output from the DVI slot after the automated configuration is complete. This can be fixed by manually editing the configuration files
• Userful Multiplier version 325 will support direct DVI (not DVI-D) input without the use of VGA-DVI converter.

Will Likely Work

Any video card supported by Linux (unless listed in the "Does Not Work" Section below) will likely work just fine with Userful Multiplier. Hence most cards will fit in this "will likely work" category. Userful Multiplier is designed to support all single, dual, and quad-headed video cards, supported by X.Org/XFree86. Any video card combinations where you can start X in multi-headed mode (i.e. multi-monitor, multi-display) should work with Userful Multiplier. Below is a partial list of untested cards which will likely work.

• Cards with DISPLAYPORT
• ATI
  • Rage XL QUAD Display Card
• NVIDIA
  • e-GeForce 6200

If you have purchased a card (not listed in our "Known Incompatible" section below) with which you are encountering problems, please email us at multiplier@userful.com and we will work with you to help resolve the problem.

Known Incompatible

• Cards with a HDMI standalone port (does not include DVI-to-HDMI adaptor port)
• ATI
  • Radeon HD 4000 series
• NVIDIA
  • GeForce 100/200 Series

Please do not purchase or contact Userful support regarding these video cards. We expect support for these video cards will be included in future releases. However, they are currently not supported.
