What are you doing on the laptop when this happens?

Depending on conditions, a GPU may be shutdown if it is not needed. Also, some programs may not work with SLI.

From the looks of things in the screenshot you posted, your video cards are not running in SLI mode. I'm not very familiar with nVidia's drivers, but is there an option to turn SLI on or off, and if so, what is it set to?

Also, MSI Kombustor does not appear to run in SLI or Crossfire mode. I just tried it on my desktop, and got the same results as your screenshot (one GPU fully loaded, the other idle). I do know that my Crossfire setup works. I'll keep looking into it, maybe there's some setting that isn't set correctly.

Ok, after doing some investigating, I found out that it is possible to run Kombustor in SLI/Crossfire mode. It just takes some trickery and has to be run in full-screen mode.

However, if SLI mode is not working in games, you would have a different problem.

[Hello man]

SLI works like so. The first card splits the work in half, sending the other half off to the other gpu via the bridge or chipset, then once processed, the gpu sends it back across the bridge where the second card compiles it and sends it off to join the other data being processed by the cpu and other components. Because of that, the first GPU will always be hotter and be working harder with more memory used because it has to store the data the second card sends back.

What is your Nvidia control panel setting? Go to your control panel and make sure it is set on SLI. If it is, and you are still running hot on one card, your driver could be bad. You can try downloading a good program called GPU Z to see how much work each card is doing. If one is doing nothing even at idle, your drivers are almost certainly bad, or your other PCI express slot could have issues. My advice after doing all of these tests would be to use either Driver Sweeper or just do a complete un-install of your drivers, then download again in a different browser. Out of curiosity, what OS and motherboard are you using? That could help me trouble shoot.

P.S. Thanks for picking me as the solution. Its my first one!
