I have two Titan Xs' and while doing a stress test I am, only seeing one being utilized (97%) while the other is not (only 1%). I have SLI enabled in my nVidia control Panel. OR is SLI ONLY operating during gaming?

I am running the MSI Kombustor Benchmark.

The only time I see GPU (1) running is if I disable SLI, otherwise, most (if not all) load is on GPU (2) - that 97% I mentioned. Could this be a bad card?

I figured it out. It's all good. SLI works perfectly and smooth. :) So, no bad card or mobo slot. ;)

I'm getting good at this, lol.

For others out there who would like to know if your SLI is working if you know if it is indeed enabled, here is what you do;

*In the Nv control panel > 3D settings > enable SLi indicators.

*Open a game/program that you know SUPPORTS SLI and you should see "SLI" with a green box next to it to the left of your screen. Next to "SLI" there should be a vertical green line from the top to the bottom of the screen. If you see this green line bounce from top to bottom, this indicates both cards are working and in SLI (in tandem/together/in Sync).

**NOTE: Not all programs or games support SLI, so if you don't see that green line during play/testing/benchmarking, be sure to confirm support for SLI for that particular program.

Thanks for posting. Figuring out how everything works is one of the joys (or not) of owning a pc. Awesome
