Is there anyway you can do sli on a crossfire motherboard? Without it being compatible?

So as i have said, in my previous question. my brother has a GIGABYTE GA-p55-ud3(crossfire). that only supports crossfire. now he has a nvidia card. and wants to buy another one the same. but does not have support for SLI. he only has support for crossfire. is there any way to work a way around that to get support for SLI. without buying a new motherborad.

The P55 north bridge on the board supports both crossfire and sli http://techreport.com/articles.x/17513. I don't know about the board itself. Ill do some more looking.

"Lynnfield's PCI Express lanes can be configured as a single x16 link or split between a pair of x8s for multi-GPU configurations. CrossFire support is universal, but as with Intel's X58 chipset, SLI certification is handled at the motherboard level. All boards should be able to combine a single GeForce graphics card with a second one for dedicated PhysX acceleration, provided they have a second physical x16 slot. You can also add a dedicated PhysX card to an SLI-certified board running a pair of GeForces in tandem. If that wasn't excessive enough, some uber-high-end P55 boards will also feature nForce 200 chips and support for three-way SLI. Such extravagance seems silly given the P55's mid-range aspirations, but that's how mobo makers roll these days."

EDIT: http://www.intel.com/products/desktop/chipsets/P55/P55-overview.htm Says that it's dependent on the motherboard design. It will not work.

I also read that both slots will run 16x4 on this board. http://ee.giga-byte.com/products/mb/specs/ga-p55-ud3_10.html

"Offers up to 2.5GT/s for fast access to peripheral devices and networking with up to 8 PCI Express* >2.0 x1 ports, configurable as x2 and x4 depending on motherboard designs."

It really isn't feasible even if it runs at crossfire or sli. You should get a new board either way if you plan on running 2 cards. Otherwise they will run horribly, or at least the second one will.

My final answer: Although the north bridge supports it, the board doesn't. There is no work around. :(
