there are some posts out there that claim to have a solution to make SLI work on chipsets not originally intended to run multi nvidia set ups.
I remember reading a few months back on Custom PC that despite everyone thinking it was a hardware issue, it turns out Nvidia rely on a piece of sftware to make SLI work.
Now both the P6T and P6TSE have the same chipset so in theory it should be possible.
If I can come across the original post on how to "force" sli on non SLI boartds I will post the link
I am waiting for the bridge to arrive.
Had to order from the US there was none in Australia !
The P6T SE didnt come with a bridge, I am guessing the crossfire with dual ati cards doesnt use a bridge ? Not sure, the documentation doesnt go into enough detail.
