I have 2 quad cores on my pc and 2 GPU's on my pc as you can see from the System Setup at the bottom.

I did get the machine to run 10 work units at once for a couple of hours but after a reboot it went back down to 9.
I can't understand why though.

I have both Graphics Cards plugged into the same monitor as it has two connections. DVI and VGA.

Anyway, when the CUDA work was finished it didn't get any more work for the GPU's.
I'm presuming that is because of my settings on the Seti Site and the fact that the CPU's already had more than 3 days of work left.

So the GPU's became idle, which is annoying as they could have been doing work at the same time.

I have disabled the SLI using the NVidia program that is installed with the Graphics Cards and left the bridge in place as it says to do so on other forum pages and also enabled the computer to see both monitors. (or what it thinks is 2 monitors)

Q1 Is there any way to make the computer download work for the GPU's even though the CPU's have enough work to do for the next 3 days?

Q2 How can I get my PC to do 10 Work Units again like I saw it doing for about 2 hours prior to shutting down for the night.

Q3 In the Status column of the Tasks Tab I see

Running (0.18 CPUs, 1 CUDA)

but I see it twice!

I thought it should be showing one item with 1 CUDA and one item with 2 CUDA

Q4 If I were to install Boinc 6.6 would it fix any of the problems above and get 10 work units running again?

==============

When I said the above, perhaps I should also have said that there are only 7 cpu work units going at that time as well when I have 8 cores... does this make a difference to anyone replying to this post?

Why not? You are running two tasks, one on each GPU.

The eighth CPU is occupied with two times 18% data feeding for the GPUs. That is a feature, but not as designed, as I have been advised ;-)

Computer sind nicht alles im Leben. (Kleiner Scherz)

SETI@home classic workunits 3,758
SETI@home classic CPU time 66,520 hours

Ah! OK then, so now I can see why the manager shows 9 tasks running instead of 10 if there is Cuda stuff left to do. Now perhaps you can explain this...

If CPU 8 is controlling the 2 GPU's whilst they are running Cuda tasks, how is my computer then able at times and for short periods (20 minutes ish when I have noticed it) to control 10 tasks instead of 9. :oS

I can understand now that if CPU 8 is controlling the GPU's then there is only 9 actual tasks running.
I can also see why when all the Cuda stuff runs out it drops to 8 and stays there till Seti asks for more work.
This is because the settings I have set ask for 3 days of work and there is still nearly 3 days left of work to do on the Astropulse stuff as the Cuda work is finished pretty quickly.
Then the Seti project asks for some more work at which point it goes back to 9 but I can't understand why now and then I see 10 tasks running when I hover the mouse over the Boinc icon in the clock area, if one of the CPU's is for controlling the GPU's.
I have even opened the manager at these points and counted them to make sure I'm not imagining it and I'm still puzzled by this.
If it can run 10 projects for 20 minutes when there is Cuda work available why can't it run 10 projects for several hours until all the Cuda stuff is gone at which point it should then drop back to 8 CPU's doing work and wait for more work to do on the GPU's.
It's a pity they haven't sorted it out yet and enabled the GPU's to do Astropulse work units too, but I guess that will come in time.
