Need help! Folding on Kepler GPUs with Tracker V2

Here is mine. First one is a single 680. The second is when I start the second 680, third is the setup...

Please note... This looks (At this time) to be 100% my issue. I need to do more research, however it seems GPU0 and GPU1 are one and the same in my setup. When I look at the log is shows Process 5476 is currently running and may also be a client with Mach. ID 2 in GPU1's FAHlog... So I stopped GPU1 and Started GPU2.... Still having GPU0 drop PPD by about 8k per day. Yet GPU2 is now showing job 8009 and 1% complete at this moment. Seems I need to remember some old school setups

OK.... Not sure how or why, but no matter if I am running one instance or two instances both GPU's are being used by either WU. This is weird! Note I "Stopped" GPU0 and am only Running GPU2 in this example. I can swith (Stop GPU2 and start GPU0) makes no difference. Both 680's go full tilt...

Make sure each client has a unique machine id number. If not you should be able to change the machine id number in the config file.

After stopping the clients, did you look in task manager or process explorer to see if there was still an FAH client running? Sometimes the process looks like it's stopped in the tracker, but continues trying to run in the background. If it's still running in task manager, kill it and start fresh again.
I'm not sure how the Tracker gets it's GPU assignments from, but it's always had my cards backwards (so GPU 0 is actually controlling GPU 1 and vice versa)

^^^ Yes... It did show them still working. And see below for a long run. For one reason or another the two cards are merged together and folding as a pair. Once I turn off the second card, walla... 17k ppd out of one card. Does not matter which one. Seems foolish to run two GPU;'s that give the same performance as one does at half the heat and energy used...

Good thinking... I looked... GPU0 is #2 and GPU 2 is #5... And it finished the second one a few moments ago.. And almost instantly the single GPU jumped back to 17k+...

Sounds similar to the old SLI issues we had, I assume you've already tried toggling SLI on and off though.

Have you eliminated the video driver as the problem?

I agree, this is a lot like the old SLI issues we had. Yes I toggled the SLI. Had no effect =[. However I have not turned off Surround and wonder if that is the issue. I plan to try that tomorrow and see. Did a lot around the home today and did not have as much time as I hoped on this...
@ Horvat... I am using the new betas and the previous WHQL did the same thing.
Greatly appreciate your help fellas. Thank you...
