The NVIDIA Quadro NVS graphics card is designed for business applications, such as financial analysis and emergency response. If you're not getting the performance you need from this card, and you have tried adjusting the settings of the software with which you're using the card, the next step is to adjust the speed of the card itself. This process is called "overclocking." While it's a perfectly legitimate option that can be done through "control center" software, which typically comes with graphics cards, you should know exactly what you're doing before attempting it.
Click the desktop icon for NVIDIA Control Panel to launch it. Alternatively, click "Start" > "Applications" > "NVIDIA." Select the NVIDIA Control Panel from the applications list.
