Any suggestions?
Dummies on one of the DVIs and the HDMIs for each card? Desktop extended on all dummie'd ports?
I have monitors plugged into all 6 DVI ports and have visal on all 6, I have tried using HDMI adapters as well, if this was not right I would get 'GPU not supported' error not 'Unstable Machine'. I am fairly sure that it is the bottom card hat is not running. It runs fine on all 6 in XP-32 but only 1.5 GB of the 12 is usable after the GPUs take their share and the customer has specified V64, the machine was ordered specifically for crunching/CUDA by a leading UK unversity. Am I right in thinking that if Folding@GPUwont run on all 6 GPUs then they would also have problems running a different set of CUDA apps across all 6?
Here is my method
I create Folders on the directory and nme them FAH1 FAH2 FAH3 etc
Then I copy in the zip file from Stanford for "High Performance GPU Clients" Console into each folder. I use Vista 64 so I choose the client that supports this OS.
In the FAH1 folder I extract the app and rename the .exe FAH1 so I can tell them all apart. I right click and "Copy" the .exe and then "Paste ShortCut" to my Desktop (or wherever you like). I right click and open properties on the shortcut and add the flag "-gpu 0" and close properties. Then I doubleclick the shortcut and this opens the console window which prompts for User name, team name etc. When you get to Advanced Options type Y and when you get to accept Scientific Work Units type Y and when you get to Machine ID type a different number for each client/card/core (some cards have dual cores) i.e. 2,3,4,5, etc.
Now to set up the next client for the next core you will need to make up a Dummy Plug if you are running Vista. XP you will be good to go at this point. In Vista take a DVI to VGA adapter and follow My Dummy Plug Guide and 30 seconds later plug that dummy plug into your next card (or if you run multi monitors skip this and plug in a monitor) now you need to extend your desktop onto the "monitor" the dummy plug makes Vista "see" as a generic PnP monitor.
Repeat the steps above for altering the shortcut except use a unique number for the "-gpu X" flag and ditto on the Machine ID when in the console config window. That is all there is to it.

Hope that helps.
In XP you do not need to use Dummy Plugs...but Vista won't let you get started if you do not extend your desktop to the additional cards/cores.
