Ok, then the only other thing i can think of is you have to make sure that your work units are not failing. That or you have yet to finish 10 units successfully to be illegible for the quick return bonus.

Switch to driver 373.06 :)

Put - 368.81 - 373.06-378.78- 381.09- 382.05...

Why, after installing fah-installer_7.4.15_x86_64.exe, only one card is active, the rest are Readi, and at 7.4.4 all work?

the beta software is slightly buggy in that it takes manual setup to get it working right. in all honesty running 7.4.4 will not loose you any PPD as the client just accepts, directs, and uploads work units from stanford's servers.

 Two video cards perform the same task 11418 . How can I stop or delete a single task?

There are different tasks with the same number.
There are numbers after 11418 you will not get two WUs that are exactly alike.
It is best to not delete tasks, let them finish and get turned in.

if you need to you can manually force the client to use different cards. you do this by going to Configure->Slots and edit on each GPU slot, you can also delete the CPU slot here. once the edit window pops up go to the bottom where it says "opencl-index" and "cuda-index" and replace the -1 in each with 0. on the next GPU slot set those to 1 and on the next set them to 2. this way each slot is accessing a different address and is manually overriding the automatic assignment.
