    actually for a new card not too bad, riva doesn't support yet but the old standby's like ati tool and amd gpu tool work (with a little help from updated tool lib.) speeds are not the issue, so far no voltage in software though the card supports it.

    I doubt the software voltage adjustments will be out in less than a month so I will hardmod mine as soon as my blocks are modded. (today at work..lol).

    Thanks for the guide Monkeywoman, can't believe there are mods for this card so soon. Can't wait to try this on my powercolour when/if it arrives.

    I'm not a vmod expert by any means, but by looking at it, I don't see why it couldn't be. Just shade in the spot with a lead pencil, the more lead, the less resistance and therefore more voltage? Or maybe I'm wrong.

    thats looks great, I like how ATI facilitated the common modder by leaving those points all isolated :P seriously though, I'm doin' this mod before I even run my card, I'm pretty confident I can hit those solder pads

    Why?

    Because if you mess up, there goes a $400+ video card? :P

    If you view the image themselves, not on the page, they are larger (not much), for anyone wanting to see a little bit more detail.

    it doesn't fully support it but fan control and monitoring work just fine. overclocking in Riva only clocks the second card from what i have checked but like you said, AMD GPU Tool works just fine.

    i don't quote in my signature, but best WR ever...

    can someone post pics of the back of their card on here? I'm going to do this, and I'm sure I have it right, but want to see it in action.
