well i appreciate any help you have given tito, i am not sure but i did read somewhere that the HAL might have to be showing to the nvidia drivers that it is a supported chipset eg X58. and as you can see mine is not showing as this. i wonder if a modified HAL might work.
i think you might be right my friend, i think the modified HAL may be a better option as the patched drivers are only available up to around 310.70 and modifying the HAL should allow later drivers to be fooled into allowing SLI
