Aaron, I have very similar gripes. My Samsubg 240T (1920x1200DVI) also will not run in SLI mode at the native rez. I tried all beta drivers (66.93/71.24/71.40) and found that even 1920x1080 at 60hz would lock up. Then I came across the new 71.80 driver. Although it will still lock up at 1920x1200DVI, I CAN run 1920x1080DVI (widescreen). I can game in SLI like this and any rez below this also works in SLI. I am still pissed I can't do native rez in SLI, but at least some progress is being made in the drivers. I think part of the problem is SLI doesn't seem to support "reduced blanking". 1920x1080 is the highest rez I can do at 60hz. When I try 1920x1200, my 240T needs 52Hz, but I think SLI doesn't support anything under 60. In addition, I have tested each of my cards by themself and each will do 1920x1200 DVI by themself (not SLI). This is definitely an SLI DVI problem and is UNACCEPTABLE.

One last note: the 71.80 drivers have advanced timings and in DVI mode I can access them all. I also can choose "DMT" and "CVT" and "CVT-RB" modes. The latter (CVT-reduced blanking" I thought would fix my problems. But with SLI this is still a no go. I think SLI doesn't allow these things to work.

I hope NVIDIA finds a fix soon. We paid too much to go through this.

I am confident that nVidia will work this out. I mean...they just came out with the Quadro line of SLI cards. If they don't make dual monitor setups for those cards, then they miss that target market. It's just a matter of time. In the meantime, when I want dual monitor setup (surfing the internet or working on documents), I turn off SLI, reboot, and I am good to go. When I want to play my games, I turn it back on, and run on only one monitor.

Nvidia has a new driver 71.89
placed in the web 2 -5 days ago

Is the first driver that will allow to turn "off" SLI in a ASUS Deluxe from the driver and back "on" with no difficulty and no lock.

this will allow Apple Cinema used to turn SLI "off" so they can play games in a lower resolution than native.

SLI work fine in native 1900x1200 resolution but most games do not go to this resolution.

Nvidia in the Release Notes for this driver for the first time admits there is an issue with Apple Cinema monitors and SLI and recommends to use NVIDIA 6800 Ultra with 512 MB ( and pass on SLI) for now...
