    I have an M17x R1 running 280m's in SLI. Recently did a clean install of WIndows, Used the latest nVidia drivers edited for my rig, and everything seems to be running like a dream, except that when I do a Furmark burn it shows I'm only using one 280m. When I run Diablo III the temp on one GPU soars to about 82C, and the other stays in the 30s. The nVidia experience shows that SLI is enabled. Can anyone help? It's running exceptionally well on one GPU but I'd like to have both for more intensive games. Thanks!

    This is likely a driver related issue. You should try going back to an older driver.

    Don't disturb your drivers just yet. It might actually be working fine. Furmark is unreliable and potentially damaging to the GPUs. I would not use that. Furmark itself only uses SLI with special configuration and using it is probably why the primary GPU temperature got high.

    What does GPU-Z show? If it shows SLI is enabled, then it probably is and there may be nothing to worry about. You can confirm this in-game by enabling the SLI Visual Indicator in NVIDIA Control Panel (or using NVIDIA Inspector) and watch the green bars, or you can use RTSS OSD to watch GPU utilization.

    Does Diablo III even support SLI? Try another game.
