SLI No longer working on GTX 580's after 313.96 update continuing to current drivers

[HanSolo71]

I have attempted to update to the newest drivers once again to find that my SLI no longer works and that my drivers cease to function. I am on Windows 8 Professional x64 and have one EVGA GTX 580 Classified 3GB and one ASUS GTX 580 1.5GB stock. Previously using the coolbits key I have been able to easily enable my SLI feature but now one I enable SLI one of my two screens turns off, my NVIDIA Control Panel locks up, and upon restart neither video card is seen by the system. Rolling back to 310.90 fixes this issue but I would like to get current for Bioshock Infinities.

According to NVIDIA this is no longer support, hopefully there is a workaround out already though.

Any help would be appreciated.

Whats the Rest of your system? I don't think I can help, but I guess that might useful to someone else.

Do you need to use the coolbits to enable the different GPU SKU's to SLI?....I thought it was supported in the drivers natively...it would just disregard the extra memory of the EVGA GPU

Coolbits is indeed required in order for SLI to work.

due to the different memory configs?
