I have set up a computer with a GeForce 9800 GT NVIDIA graphics card. The computer runs without a monitor, keyboard or graphics card. I monitor it using Boinc Manager or BoincView. If I have to I log into the computer using windows remote to log onto the computer, update software or whatever then restart the computer.

I have set up using ap_5.00r103_SSE3 to crunch AstorPulse and MB_6.08_mod_VLAR_kill_CUDA to run MultiBeam. Astropulse is running fine on the CPU's and work unit times are normal. The CUDA app is running very slowly. 2 or 3 hours to complete a work unit but it does finally complete it and verify for credit.

Other abnormalities. When I log into the computer I cannot access NVIDEA control panel by right clicking on the desktop. That menu item is not even listed. Task manager lists nvsvck32.exe which I assume is the NVIDIA video driver so I am assuming that the video driver is fully loaded. However CUDA tasks continue to run extremely slow. I still believe that it has something to do with a monitor not being attached and have installed a dummy vga plug but still CUDA is running slow.

I believe that since their is no attached monitor that the NVIDIA video drivers are not being fully installed. I have installed a dummy vga plug onto the video card but it still runs slow. I then attached a real vga monitor to the card and the CUDA app is now crunching full speed.

So the question is "How to make a DVI to VGA adapter that will trick the video card into believing that a real monitor is attached?" I have tried one with just 3 75 ohm resistors but that doesn't do the trick.

Any Suggestions?

Found out that when you are using Windows Remote that it installs it's own display driver, by-passing part of the NVIDIA driver.

I set up RealVNC on this box and confirmed, CUDA now going full speed and computer is using and reporting NMVIDIA drivers when I log in with VNC.

Now problem is I cannot get RealVNC to connect on my other remote box. I get a fault code 10061. Using the free version. Think that is why???

The remote box says the VNC server is running but I can't connect to it from my main computer. CUDA remote box works ok.

I am having the same type of problem only on an 8500GT. When CUDA is "on", the system recognizes that it's there and assigns a task. BUT, the task is assigned 1 processor at only 0.07% and the CUDA. I then get only about 1 cpu computing second every minute.

I am using the graphics card for my monitor and have cpu times set to a maximum of 100% when idle and 90% when active. I don't see anywhere to set the gpu activity.

Where did you do that? AFAIK you can only do that for memory usage.

I don't see anywhere to set the gpu activity.

Because there isn't any (yet).
