Dont recognize the 295GTX

Linux: CENTOS 5.4
CUDA: 2.3
driver: 190.18…

I have two cards: Geforce8400
295GTX

Linux recognizes only the Geforce8400.

What can be the problem?

Thanks

What do you mean by “recognize”? That is a pretty vague description.

Is the GTX295 correctly enumerated and visible on the PCI bus, for example? Can nvidia-smi find the GTX295? Does nvidia-settings show the GTX295? What CUDA devices does the SDK deviceQuery show? etc…

PCI bus:

02:00.0 PCI bridge: nVidia Corporation PCI express bridge for GTX 295 (rev a3)

03:00.0 PCI bridge: nVidia Corporation PCI express bridge for GTX 295 (rev a3)

03:02.0 PCI bridge: nVidia Corporation PCI express bridge for GTX 295 (rev a3)

04:00.0 3D controller: nVidia Corporation Unknown device 05eb (rev a1)

05:00.0 VGA compatible controller: nVidia Corporation Unknown device 05eb (rev a1)

06:00.0 VGA compatible controller: nVidia Corporation G98 [GeForce 8400 GS] (rev a1)

nvidia-settings show the GTX295 but:

nvidia-smi:

NVIDIA: could not open the device file /dev/nvidia0 (Input/output error).

Failed to attach gpu

Could not allocate resources!

deviceQuery:

CUDA Device Query (Runtime API) version (CUDART static linking)

NVIDIA: could not open the device file /dev/nvidia0 (Input/output error).

There is no device supporting CUDA.
