yes - go to your Einstein@Home account webpage and click on the Einstein@Home Preferences link. there you will see a list of preferences. the last one at the bottom called "GPU utilization factor" is what you're looking for. its default setting is 1, which corresponds to running a single task at a time on your GPU. if you change it to 0.5, it'll force BOINC to run 2 tasks on your GPU simultaneously. 0.33 corresponds to running 3 tasks simultaneously, and so on and so forth. basically, the GPU utilization factor is the reciprocal value of the number of tasks you want to run simultaneously on your GPU.
Sorry I should have said on this machine which has the gtx220 and I have not put anonymous platform on this machine yet .
Does that make a difference to the setting as I did make the changes to preferences but didn't start doing any extra units still only doing 1 unit on the GPU and it has downloaded extra units

This field has a warning about changing this value. Can someone explain what the risks are with increasing the # of jobs on a GPU. Are the risks "heat" related and the need to provide greater cooling for the GPU/PC? Or is there something else?

I believe the warning refers to heat. i.e. "if your graphics card dies from heatstroke after having changed this setting don't come complaining to us".
I (and many others) have run multiple jobs on our cards for a long time. I have never noticed any issues. Modern cards throttle down when going too hot but you can monitor your card temperatures with a tool like GPU-Z if you like.
In addition to Logforme's answer about heat it can also apply to a too weak power supply. Stressing the GPU requires more power so a PSU already running close to max can go over the limit and possibly fail and maybe also take other parts with it if you're unlucky.

Thanks for the headsup, but I believe GPU-Z is for Windows only. If you are running Ubuntu you can install Psensor. It is part of their package. Not a slick as GPU-Z looks but gets the job done.
The current temp for my GPU is ~55C. This seems a bit high. What are the average temps that others experience with respect to their GPUs?

Note that the change only affects new WUs; not ones you've already downloaded.

It is applied to previously downloaded work too, but the setting is only transferred and applied to your computer when new work is downloaded.

NOw if seti can do that even better in stead of what you have to do there

That sounds about par for the course for upper half of the range nVidia cards on air (assuming an ambient air temp in the mid 70's F).
My Radeons run hotter than that (around 70 C st the same ambient temp).
I also have a couple of Zotac GT430's. They're passively cooled, so I added an extra case fan for them. They run around 40 C.
