xdevs.com wants to add SLI support to every chipset, regardless of the certification. They've come a long way, Nvidia's multi gpu technology has been succesfully tested on chipsets of both AMB and Intel that don't support it. The hack thankfully uses the simple verification in X58 motherboards, that verifies the certification of SLI on a chipset. A modified driver from xdevs.com makes the Nvidia drivers think theres a X58 chipset in the motherboard.

The hack works on all modern Windows systems; Windows XP, Windows Vista and Windows 7, both 32bit and the 64bit editions. The hack has been proven succesful on the following chipsets: the X38, X48, P35, P45, 790X and 790FX chipsets, as long as the motherboard contains two pci express x16 slots.
