Determining the AGP version
Determining the AGP version.
New video cards may require a certain version or specification of AGP for the card to work properly. Not meeting this specification may cause the computer to lock of freeze during game play or may not allow for a video card to be connected to the AGP slot.
Determining the AGP slot version
It is recommended that you locate the version of the AGP port by reviewing your computer motherboard documentation or the motherboard manufacturer's web page.
When locating the version of AGP your video card it is important you locate the version and not the transfer rate.
Transfer rates of AGP can be 1x, 2x, 3x, 4x, or 8x.
Versions of AGP can be 1.0, 2.0, or 4.0...
The transfer rate of an AGP port is completely different from the version of an AGP port. For example, a motherboard AGP port may have a transfer rate of 2x but have a version of 1.0. If a video card or 3D accelerator requires a version of at least 2.0, this computer would not support this video card.
Also, the product documentation or specification may list the available voltage or AGP Signaling; often the supported voltage will be 0.8V, 1.5V, and 3.3V. Make sure the AGP card supports the voltage of the motherboard.
