Incompatable AGP cards!

[Moohooya]

Over at Tom's he mentions incompatable AGP cards! Yikes, I never knew ther was such a thing. I have an old Matrox G400, I forget if this is AGPx1 or x2, but I know my current mobo is AGPx1. Will this work in a new mobo?

What are the two voltages, 3.3v and ? What versions of AGP use which voltages?

Thanks all

The G400 cards are keyed (from the examples I've seen) for use in either 3.3v or 1.5v AGP slots - ie. universal keyed. It should work in pretty much every AGP slot.

Well that makes sense that the AGP card and slot would be keyed for different voltages, but then why would the new Asus board Tom's Hardwareauto detect of the wrong card is plugged in? Are they just paranoid?

Anyway, you think I'm set. Are new AGP cards and mobos now 1.5v then?

As far as I know all of VIA's current Athlon based boards use the universal AGP slot (no specific keying) as well as AMD chipset based boards. Cant say for SiS.

As far as the P3 goes, I think all of the current motherboard chipsets for the P3 (not sure about Tualitin boards) support the universal connection also.

Its Intel's P4 chipsets that are picky.
