Your AMD motherboard isn't compatible for SLi.

You used to be able to use CoolBits to SLI cards with different memory amounts. This was even officially supported by nVidia at one point. However, I don't think it works anymore and nVidia has gone back to not supporting SLI with different memory amounts.
