Quadro 6000 and GPU-Z Quadro 6000

Hello I´ve bought an new Quadro 6000. When i want to see the tec specs from the card with GPU-Z i`ve got wrong specs. These are the details:
GPU: 06D8
MEMORY SIZE: 2048 MB

Is this an Error of GPU-Z ? Is there any tool from Nvidia to verify the geniue of the Quadro Cards ?
Sorry for my bad english.

Control Panel => Nvidia Control Panel

Or Right Click on desktop NVIDIA Control Panel.

It also looks like you need to install the drivers:

Download your driver first and install, restart your system and run CPU-Z again.
