zeropoint 71.84's creates a black screen with SLI enabled after the reboot. it was the first driver installed. the problem does not occur with nvidia's 71.89.
we are currently looking into this, and are not 100% sure why our drivers don't work very well with SLi. For now we reccomend sticking with official drivers for SLi, as SLi is fragile, at best.
Fragile is an understatement. I'm currently using 71.89 official, and it took me a good month or two to get things working okay. Now I have an error where if my machine has been running for a substantial period of time, launching a 3d game causes the screen to go black and I have to hard reset. If I restart before launching all is fine. Someone suggested this might be some sort of memory leak a program has rather than a driver error. Anyway I can find out? Is just looking at process memory usage in the Task Manager enough? anyone else had this problem? Roll on DHZP SLi.
