OK, so I'm trying to understand the correlation between the signaling voltages of my AGP slot and the potential video cards that would be compatible with my set up. I've done some research on the Internet, but am still a little hazy. If somebody could clarify some things for me, that would be great.
Basically, my AGP slot is version 2.00, current AGP speed 4X. The way I understand it, I should be able to run any video card that is 4X/8X and even possibly an 8X video card because of backwards compatibility. However, the potential flaw to my understanding here has to do with the signal voltage my AGP slot is geared for. Near as I can tell it is 1.5V. I looked at this illustration
and matched my AGP slot to the second choice from the top titled 'AGP 1.5 V'
The way I understand it, AGP 1X/2X is 1.5V or 3.3V, 4X is 0.8V or 1.5V, and 8X is 0.8V specifically. I believe some AGP 4X slots are compatible with both 1.5V and 0.8V, but don't know if mine is. That's the question. If my AGP slot is 1.5V, does that mean it is compatible with a video card that is 1.5V and 0.8V?
A friend of mine bought a new computer and gave me his Sapphire HD 2600XT video card. He swears its 8X, yet Sapphire's website shows the specs on this card to be 4X/8X. I'm not sure I should install the video card for fear of burning out my mobo.
