Einstein wants to run 4 tasks on my NVIDIA GeForce GTX 650 Ti. That's too much for the old girl. How do I lower the task count from 4 to 2?

How do I reduce the number of GPU tasks?

Have you changed any settings for how many GPU tasks to run at once?
The standard setting is to run 1 GPU task at a time.

The two usual options for controlling the number of GPU tasks to run are:

In Your Account -> Einstein@home preferences -> GPU utilization factor, set it to 1 to run 1, set it to 0.5 to run 2 at a time, set it to 0.33 to run 3 at a time and so on. Changing this setting will not take effect until new work for the GPU has been downloaded.

or

In an app_config.xml file, for a normal install this file doesn't exist, it's a file that the user needs to create if the user wish to control, amongst other things, the CPU or GPU usage of an app. The documentation for the usage of this file can be found here.
If you yourself has created a file like this then change 0.25 to 0.5 for the app in question and then in Boinc Manager select Options -> Read config files.
