    i was just woundering, are AGP x4 cards backwards compatible? for example i have a 440bx motherboard witch says it suports x2 AGP and i wanted to know if it would run a x4 card. is voltage going to be an issue like like those m/b's that only run x4 cards?

    anyway...

    I wouldnt count on it. A 1x card will run in a 4x slot, but I dont think a 4x card would run in a 1x slot. Otherwise there would be no point in having them!

    Yes it will work fine, just you wont get the benefit of the faster 4x interface

    I thought AGP 4x also had AGP 2.0 which supplied the larger amount of power needed to AGP 4x cards?

    That analogy would work if you replaced 1x with 2x.
    The voltage 1x AGP cards were given was 3.3V(afaik), whereas nowadays 2x/4x/8x are all supplied with ~1.5V.
    Therefore, I would assume that 2x and 4x (and 8x) cards won't work in 1x slots.

    I thought that AGP 1X cards used 3.3v but the slots supported 3.3 & 1.5v, AGP 2X was the same (I think) and AGP 4X & 8X use 1.5v and only some AGP 4X slots support 3.3v cards.

    I sucessfully used my GeForce 4 Ti4200 in my AGP 2X (Apollo Pro 133) motherboard.

    This "4x cards not working 1x slots" is full of shit. I have run my Gf3 ti200 card in my old pII mobo and its fine.

    As I thought, although it isn't always true the other way around, I'm not sure how it is for the AMD boards, but I know that all Intel chipsetted P4 boards only support 1.5v cards.

    You should be fine as long as it is not an older card in a new motherboard, the other way should work fine.
