Installing your Matrox Radient eV-CXP board 19
10. Turn on your computer.
❖ When you boot your computer under Windows, Windows’ Plug-and-Play system
will detect a new Multimedia Video Device and you will be asked to assign it a
driver. At this point, you should click on Cancel.
Under Windows and Linux, the driver will be installed during the installation of
Matrox Radient eV-CXP software.
11. Disable active state power management (ASPM) for PCIe devices, to maximize
the performance of Matrox Radient eV-CXP. In the BIOS, disable all ASPM (or
equivalent) settings (typically accessible from the Power management submenu
of the Advanced Configurations menu). In addition, if the operating system has
an ASPM for PCIe devices option, disable this option as well. For example, in
Microsoft Windows 7, open the Power Options dialog box from the Windows
Control Panel. For the currently selected power plan, click on Change Plan
Settings and then click on Change Advanced Power Settings. In the presented
dialog, expand PCI Express, and then expand Link State Power Management
and set it to Off.
