  1. What are the system requirements for the V2 1000 adapter?

    A Pentium 90 or higher with 16 megs of RAM or more and a 2.1 compliant PCI bus. Remember that the software for the V2 may have different requirements to run properly.

  2. Will the V2 1000 adapter run with my existing display adapter?
    Yes, the V2 1000 adapter is designed to run with the current display adapter that is in the system.

  3. 3. Will the V2 1000 adapter work as a stand alone display adapter?

    No, the V2 1000 adapter is not a stand alone display adapter. The V2 1000 adapter requires a primary adapter installed into the computer in order to function.

  4. In the "System Info" utility of the 3dfx Voodoo2 tab, my adapter only reads 8 MB of Texture memory. Where is the 12 MB EDO Memory??

    The system information will read 4 MB of Frame Buffer and 8 MB of Texture memory. So 4+8 = a total of 12 MB.

  5. What is SLI?

    SLI stands for Scan Line Interleaving. This means if you have 2 PCI cards from the same company, you can connect them together using a supplied internal cable. One of the cards would display the odd number fields, and the other card would display the even number fields. This will almost double the fill rate performance of Voodoo2.

  6. What are the requirements for the Scan Line Interleaving (SLI)? Can it go beyond 2 cards?

    Voodoo2 requires two open PCI slots, two identical Voodoo2 based cards from the same manufacturer, and Voodoo2 drivers. Scan Line Interleaving is limited to two cards.

  7. What is the maximum resolution that the V2-1000 can do for gaming?

    The V2 1000 adapter in single adapter mode can do up to 800x600 resolution in the games, and in SLI mode the adapters can go up to 1024x768 mode. When using SLI mode, please check in the utilities section of the 3dfx Voodoo2 tab that the SLI mode is enabled.

  8. What color mode should I be running in order to get the V2 1000 adapter to function properly?

    This depends upon the application's bottlenecks. If the application is bus limited, AGP may be faster than SLI. If the application is fill rate limited and not CPU bound, SLI may be faster. In general SLI will have better performance than AGP in fill rate.

  9. The 3dfx Voodoo2 tab disappeared. How do I correct this?

    To correct this you will need to shut the computer down, open up the case, remove the Voodoo2 adapter, and then restart the computer. Once the computer is restarted, go into the device manager and check under "sound, video, game controllers" section. Make sure that the 3dfx Voodoo2 adapter is not there. If it is still there, remove the adapter by highlighting it and clicking the "remove" button.

    Once that is done, you will need to start the regedit program by going to "Start" and choosing "Run". Type in "regedit". Then perform a find for the following: "3dfx", "glide", and "Fxmemmap". Remove all entries that start with any of those. Close out of regedit and do a "file find" for the same three names and remove those as well. Reboot the computer to make sure that the system boots normally. Then shut it down and reinstall the adapter and install the latest drivers from http://www.3dfxgamers.com/view.asp?PAGE=V2drivers. This should solve the issue that you are having. If the problem persists, there could be a possible hardware defect.

  10. Does the Voodoo2 run under the Linux environment and does 3dfx support the adapter under that environment?

    3dfx has provided a reference driver which is available at http://www.3dfxgamers.com/view.asp?PAGE=V2drivers, but at this time the drivers are not supported direct by 3dfx Technical Support. Should you have any problems arising from the use of these drivers, it is recommended that you direct your questions to the 3dfx Linux newsgroups.

  11. Does 3dfx provide a Voodoo2 driver for the Mac environment, and does 3dfx support it?

    3dfx provides a reference driver for the Mac 8.X operating system. These drivers are not supported by 3dfx Technical Support.

  12. I am having trouble using SLI mode with my Voodoo2 cards. What are some trouble-shooting steps?

    First of all, make sure that both cards are listed in the Device Manager under the "Sound, Video, and Game Controllers" section. Also, ensure that both cards are using the same driver.

    If you are experiencing crashes or lock-ups, a good way to test and see if it's a hardware problem is to use one Voodoo2 card by itself, and see if you still have the problem. Then swap the cards, using the other Voodoo2 by itself. If the problem you are having still happens with each card individually, you most likely have a software problem. If the problem only happens with one of the cards, you most likely have a hardware problem with that card.

  13. If I run the DirectX Diagnostic Tool (DxDiag) on the "Display" tab for the V2 1000, it reports that I have around 12 MB of memory. I am running two V2 1000's in SLI mode, shouldn't it report that I have 24 MB?

    With one V2 1000 by itself, or two in SLI mode, the DirectX diagnostic tool will only report that there is 12 MB of memory for the V2. This does not mean that SLI mode is not working. See the next question to test if the SLI mode is working properly.

  14. How do I know that SLI mode is working?

    The easiest way to find out is to play a 3d game that lets you choose the resolution you wish to use. If you can use resolutions higher than 800x600, then your SLI mode is working.

  15. Does the V2 1000 require an IRQ?

    No, the V2 1000 PCI does not need an IRQ to function.

  16. When I try to change the resolution on the Voodoo2 tab in my Display Properties, it always defaults back to 640x480. Is my card not working correctly?

    This is a common misunderstanding. When you change the resolution on the Voodoo2 tab, you are only selecting the resolution's settings that you want to modify, not which resolution you want to use. For example, move the slider up to 800 by 600, and set the refresh rate at 75Hz. After pressing "Ok" and opening the Voodoo2 tab up again, the slider will be back to 640 by 480. This is normal. If you move the slider back up to 800 by 600, you'll notice that the refresh rate will still be at the setting that you had given it previously, 75Hz.

    If you want to play a certain game at 800 by 600 resolution, that choice must be made inside the game's video options.

  17. The V2 1000 seemed to install OK, but it's not listed in the Device Manager under "Display Adapters."

    The V2 1000 is not a full video card; it is only a 3d accelerator. For this reason it will not be listed under the "Display Adapters" section. It will be listed in the "Sound, Video, and Game Controllers" section.

  18. The first time that I booted up, the system detected the V2 1000, but I can't find it in the Device Manager.

    If the drivers aren't installed, the V2 1000 will appear as a "PCI Multimedia Device." It will either be in the "Sound, Video, and Game Controllers" section, or the "Other Devices" section.
