AGP-Pro Compatibility

[Edge]

I bought a Soyo KT400 Dragon Ultra motherboard recently, but did not realise that the AGP slot is a 1.5v APG Pro slot until I got the board. My current video card is a PNY Gforce 4 ti4600 128mb DDR card, and I'm pretty darn sure it's 3.3v. I've been onto every review, retailer and manufacturer site that I can think of, but I cannot find any information about the voltage of cards. My question is this, does anyone know of some 1.5v cards floating about? I'm idealy looking for the later Radeons and Gforces.

Another question, there's a power socket next to my AGP card on the motherboard, same socket as one of the power supply leads, what does this do? The manual mentioned the slot in passing, but not its function.

Oh yes, and I have a pretty light wallet at the moment, so nothing like $400.

3.3v was for 2x and below, or AGP 1.0. 1.5v is for AGP 2.0 or 4x, which the GF4 is.

The gf 4 ti 4600 is 4x, and even I know that AGP Pro is backwards compatible.

The only problem was this, when I plugged it in and started up my computer, assuming it was the right voltage, I had some major instabilities. Every half minute or so, the computer sounded like it would turn off, winding down and the like, and turn back on, but it wouldn't affect the work on my screen. I made sure that screen savers, power saving, etc. were all disabled, too. Additionally, audio froze after only a few seconds of playing, then the entire computer as well (Running Windows XP Pro, has only done a complete freeze once before when the controller card on my hard drive died while the computer was running)

Your problem isn't caused by an AGP version issue. To begin with, AGP Pro just means it has extra pins that standard cards don't use. AGP Pro is not a speed, nor a voltage. It was available fore AGP 1.0, AGP 2.0, and AGP 3.0 cards and chipsets.

Your card is an AGP 4x card, at AGP 2.0 standards. That means it's a 1.5v card natively. While it's backwards compatable to 3.3v slots through autoswitching, it's primarily a 1.5v card and will operate as such in your system.

You might want to consider what your other problems could be, such as power. A good place for general instability issues is the Motherboard's forum.

Thanks Crash, upon further inspection I found that one of the IDE cables in my system was 40 pin and not 80 (d'oh!) which was causing some problems. Also, the raid was having some major conflicts.
