Once the second Dual card is installed correctly, the graphics driver will unlock the SLI settings. A Windows popup warns that the best results are achieved with an SLI bridge, but since the cards don't sport the necessary connector, we'll have to do without. After rebooting the system, the two cards are recognized as an SLI configuration. The GPU temperature can be monitored individually for each of the "three" GPUs. The sight of this bridge-less SLI setup is a little peculiar to us, and reminded us of ATI's Crossfire concept.
SLI without a connector- it works!
Activating SLI mode requires a reboot.
