So I had issues with tracker the other day, so I decided to remove any and all folding clients on my rig.
I have the new drivers, OS is Vista Ultimate.
I got tracker set up but I cant get the two bottom cards to run. I extended my desktop (with and without dummy plugs) and still can't get the bottom cards to work.
I used to have to trick the computer and pull the dummy plugs out before extending. This didn't work. I've never been able to get this PC to fold without plugs, even with the new drivers.
Here are some screen shots. Maybe I messed up during config.
 

 

When you updated drivers, did you use DriverSweeper and do a Clean install? It looks like there is something being left behind by an old driver and may be causing all of your problems.

I have never used the auto detect but I might try installing the driver with all cards in and see what happens.

Yes I did use driver sweeper in safe mode. Then reinstalled the new drivers on one card then put the two others in.

 
Why not just install the new driver will all the cards installed? The reason the Tracker is showing an old driver is because the cards you are adding back in later are still running the old driver.

You're not the only one having issues.  Sometime early this morning my client.cfg for GPU0 just reset itself and ever since my GPU 0 client has been starting/stopping itself all day.  Every time it restarted,  it made a new log file and didn't send any results.  Probably cost me over 5-6k in the last few hours.

So I reinstalled the drivers using driver sweeper AGAIN The device mgr says they are 8.17.12.6009 I don't know if thats the 260.99 drivers or not.
Tracker would not start the second and third client.
So I tried a dummy plug to extend the desktop, thats didn't extend.
When I pulled the dummy plug out the screen flashed so I tried to extend the desktop and it worked. I did this for both cards, now tracker started them up.

There are some very smart people on this board, someone PLEASE explain WTH is going on!!!

The problem is really quite simple.  You my friend have Gremlins!  Yes, Gremlins.  The only way to get rid of them is to turn off your computer and unplug it then make sure your cards are properly seated.  My .02.

murphy screwed with my newegg order, and as the result, after some other stuff, I am minus the free copy of HAWX 2 I would have got
 

Why what's up with the HD audio drivers? Can't I just delete them?

+1 dubzhouse!
I had the same issue with my asus board (which I just replaced with an X58). I could get one 450 to run but not the other, no matter what I did. I solved it by not installing the nvidia audio drivers part of the 260.99. You just need to uncheck the box during the setup.
I posted about this in another of our threads but could not find it again, but that's what worked for me.

Can't say I know specifically, but a lot of people have been having issues with the HDAudio drivers, especially as related to the 200 series cards.  I have always had to use the dummy plug method until did a "clean" install on both rigs with the new drivers (one vista ultimate, one Win7 Pro) and then used the autodetect feature.  After that no more dummy plugs.  On the Fermi machine I let the HD audio drivers install, but I think they're slowing down my second card which is a 275.  On the Vista machine I didn't allow them to install.
 
Good Luck, but it still sounds like Gremlins.  

Okay please take a look at task mgr and process lasso. It looks as if tracker is starting multiple clients. Same with the CPU but I shut it down before I took this screen shot. Why is tracker trying to start them twice?
 

just a fyi about hd drivers

Sad thing is Tank, I just bought this for $110 a few days ago!!! So far they are the cheapest on the net.

Have you tried it without extending the desktop? I am using the systray client and just put the flags and all four of my cards are folding. I have 2 260's, 8800gt, and a 460. Not one problem with systray.
I would just use the systray client and see what that does.
