I have got some troubles on my WinXP64. I have installed the newest version of the driver, the SDK and the toolkit but running deviceQuery looks like this:
"C:\Program Files (x86)\NVIDIA Corporation\NVIDIA CUDA SDK\bin\win64\Release
There is no device supporting CUDA.
Device 0: "Device Emulation (CPU)"

The device manager shows me the correct version of the driver and of course the correct device description (Quadro FX 4600).
The same problem again on another Win XP x64. Now I have a GTX 280 with the newest driver from NVIDIA. As graphics card for output I use the onboard ATi card. The device is shown correctly in the device manager of windows but every example program says there is no CUDA device.
This time I am sitting in front of this PC so no remote desktop problems.
What. You have it backwards. Vista will only run with a single graphics vendor; with XP that is not the case and you can use as many GPU vendors as you want (assuming your machine doesn’t become very unstable and explode violently in the process). In this case, I’m doubting that it’s even loading the driver if you don’t have a monitor connected to it, though. I’m not sure if there’s a good way around that (besides “run Linux”).
Ok, I tried both, Vista and XP and both won’t load the driver. XP does not complain anything, it is just not working and Vista says that the driver is not compatible with the ATi driver and deactivates the card.
It seams that I have to use Linux to get rid of my problems.
that is about the third time I have made the same mistake (it is difficult to guess the right position for those 2 holes for your eyes in a brown paper bag…), so I will refrain from talking about it again. I’ll just tell people to use linux ;) And the stupid thing is that it is actually easy to remember. With windows you get less option with newer versions :P
