NOTE System Board Accessory Board Slots To accommodate AGP Pro cards, the AGP PRO slot connector is wider than the standard AGP 4X connector. To meet the increased power requirements of AGP Pro graphics cards, additional pins are present at both ends of the connector. An AGP Pro card may draw power either from the existing part of the AGP Pro connector, the extended part, or a combination of the two. In all cases, the maximum power that an AGP Pro card may draw is limited to 110W in the Workstation models. Power on the existing part of the connector is delivered on 5.0V and 3.3V rails. Power on the extension is delivered on the 12V and 3.3V rails. You can use either standard AGP graphics cards or AGP Pro graphics cards that draw less than 50W of power. (Below 25W, you can use a standard AGP connector.) Power is provided through 3.3V, 5V, or 12V power rails. AGP Pro graphics cards that draw more than 50W and AGP 3.3V graphics cards cannot be used in the Workstation's AGP slot. The AGP Pro 1.5V slot is backward compatible with both AGP 1x and 2.x modes (using 1.5V signalling) and AGP 4x mode (where 1.5V signalling is necessary). For information about the AGP interface and bus, see page 49. 40 Chapter 2
