How to Identify an AGP Video Card
Before being superseded by the most modern (at the time of this writing) PCI Express video cards, the Accelerated Graphics Port (AGP) form factor video cards were designed in four different versions: AGP v. 1.0, AGP v. 2.0, AGP Pro and AGP v. 3.0. The only difference between the versions is the computer bus speed that each supports. The physical attributes of AGP cards are identical across all various brands, makes and models.

Count the number of metallic pins on the bottom edge of the video card, which plugs into the slot on a motherboard. The AGP form factor contains two rows of 66 pins, for a total of 132 pins.

Look for additional identifying information printed on either side of the AGP card. Some AGP cards will have a label on the board itself, such as "AGP 1.0", "AGP 2.0" or "AGP 3.0"; this information can also appear on one of the microchips installed on the board.

Determine the voltage type of the card once it has been identified as an AGP form factor card. Various motherboards require an AGP card with a specific voltage rating of either 1.5 volts or 3.3 volts. Lay the card so the soldered side (not the side with the electronic components) is facing upward and the connector end is facing to the right. Look at the second pin from the right (pins closest to rear end of the card) and make note if a small line runs up into the card. If so, the card is a 1.5 volt card. If no line exists, then it is a 3.3 volt card (see the Samtack site in References for illustrations).

Tips & Warnings
Use caution when handling any computer circuit board, as they are sensitive to static damage. Never touch the sides of the board or the metallic connection pads. Always handle a board by the edges. Store all boards in their protective anti-static packaging.
