why don't you forget it already ??? there's no SLI official support for CLoD, afaik Nvidia doesn't even know about CLoD. and if it does, it doesn't want it's name associated with it.
SLI went down the same river that took the clouds, weather, everything that was promised and never made it to light.
again, take a look
so CLoD is what it is, let's hope the new BOS doesn't disappoint, these guys now have the experience of a failed product so maybe they can avoid some pitfalls and make better development choices
