Motherboard question GPU

[dragoncurt]

If a motherboard says it can do crossfire but don't mention SLI I am wondering if it can though as long as their is 2 PCIe x16 slots well might be PCIe 2 x8 but won't it allow either Nvida or AMD multi gpu.

x16 length =/= x8/x16 electrically

also nvidia is weird with it has to be certified somehow

Oh right I am a bit confused by what you mean "x16 length =/= x8/x16 electrically"

 

So would a motherboard with it saying crossfire still allow it to how 2 nvida gpus in sli. 

 

Thanks

If it doesnt say it can sli and doesnt include sli bridge, then its pretty sure that you cant do sli with the mobo

If the board doesn't say it supports SLI then it most likely won't work.

Sli requires each GPU to be on a x8 or x16 slot electrically 

Crossfire is fine with x4

So mobo manufacturers may put a x16 slot but only wire it for x4
