Tesla C870 not recognized by CUDA

In relation to a project at a university, we are a group trying to get CUDA to work on a machines installed with two Tesla C870 cards. We have installed the latest driver provided by NVIDIA, together with the Toolkit 2.3 and SDK 2.3.

However, when we try to make a device query, no decices are apparently installed that supports CUDA. Instead we are shown the CPU emulation mode.

The machine runs Windows 7 Enterprise 64-bit. According to the Device Manager, there is also a device installed called “Standard VGA Graphics Adaptor”, and we suspect this might be causing the problems.

Any ideas as to overcome the obstacles? Thanks in advance!

I think it’s related to this thread.
