The picture in the manual shows an AGP pro slot (has the two sections on the end of the connector - extra power pins for cards that need them). In the center section of the connector, there are no plastic keys. That means the connector is actually AGP pro universal, and can run at 3.3V or 1.5V. At 1.5V, it can run at 1X/2X/4X At 3.3V, it can run at 1X/2X I found some really good pages you might enjoy. The first page should answer your question. If you look at the "Practical Motherboard And Card Compatibility" table, your motherboard is the middle row, and any card will plug into your AGP slot. "AGP Compatibility For Sticklers" http://www.playtool.com/PT/AGPCompat/agp.html "Video RAM Memory Bandwidth" (consult before shopping) http://www.playtool.com/PT/VRAMWidth/width.html "Troubleshooting AGP" (using tuner tools) http://www.playtool.com/PT/AGPFix/agpfix.html One question I would have liked to see answered on those pages, is what happens when an AGP 3.0 card (that only runs 3.0 protocol, and is not a dual personality card) meets an AGP 2.0 Northbridge (like yours). The register definition of the AGP speed, for the 3.0 device, is 1001=8x and 1000=4x, while for the 2.0 device, it is 100=4x, 010=2x, 001=1x, and there is no fourth (MSB) bit. What I am concerned about there, is not the video card driver, which can probably work out that it is dealing with such a combo, but with the motherboard BIOS. How can a BIOS designed for a AGP 2.0 world, deal with what it reads in the AGP 3.0 video card speed bits ? I still haven't worked out how that works. (Some motherboards "black screen" with certain video cards, and I'm just suspicious. After all, motherboards have a BIOS AGP speed setting, suggesting the BIOS does try to configure things before booting.) HTH, Paul |
