    Question SLi on CrossFire board?

    Sorry about asking this, but I've got brain fade this morning. Doh!

    Got a GF460 card to be installed in an Asus M4A89GTD motherboard (AMD 890GX chipset) and convinced myself that because this is a CrossFire-enabled board that there's no way to later bung in a second GF460 card and get an SLi config going.

    Is this correct - and I would have needed to get an NVidia chipset motherboard - or have I missed something and it is actually possible (providing I can find somewhere to get the SLi bridge from - since obviously a CrossFire board wouldn't bundle one)?

    (Actually the bundle on the Asus board is pretty dismal - but maybe that's me being cheap).

    Career status: still enjoying my new career in DevOps, but it's keeping me busy...

    Re: SLi on CrossFire board?

    Hi crossy. Im not overly familiar with the mainboard but I'm pretty sure it doesn't support SLI. It does, however, support Crossfire without a doubt. It looks like you may have to invest in an SLI compatible mainboard if this is the route you want to go. Sorry mate.

    Likely ...... but not 100%.
    The ABIT AW9D-MAX was a XFire board, but there was definitely a workaround for that to make it SLi.
    Maybe some of the others are the same.

    It does work if you use this hack :

    I have it working with two 7600GTs on a 975X board on my Vista boot. I wouldn't put it past Nvidia to break things again, but if you want a solution that works with the very latest drivers, you could always give it a try.

    Re: SLi on CrossFire board?

    Yes basically any board that can do crossfire should also be able to do sli, it used to require hacked drivers and often a hacked bios.
    However with nvidia licensing sli to intel it's now much easier to do.

    And yes you will need to buy an sli bridge.

    Although the main question I'd ask is do you actually need to sli?

    Just out of curiosity and for future reference, but did you manage to get this up and running crossy?

    Re: SLi on CrossFire board?

    Slightly off topic... Well, not really. TOTALLY off topic :0)

    But given nVidia's penchant for disabling PhysX if it finds an AMD based graphics solution in there.... does this also follow for AMD based on-board graphics?

    [EDIT]
    Scratch that, dumb question.
    The nVidia control panel on this machine with 890GX is reporting that PhysX is active.

    No, I don't need to do it - but it's nice to know that if my GF460 proves to not be up to the odd game I play on the PC then there's a route to boost it's performance that doesn't involve junking the gear I've already got.

    Apologies to all the folks who kindly posted to this thread - unfortunately my rig-building took a lot longer than anticipated (mostly due to the post!) so I didn't have the option to check my mail.
