Installation
WARNING! PCI Express cards, like all computer equipment, can be severely damaged
by static electricity. Be sure that you are properly grounded before opening your
computer case or touching your card. StarTech.com recommends that you wear an
anti-static strap when installing any computer component. If an anti-static strap is
unavailable, discharge yourself of any static electricity build-up by touching a large
grounded metal surface (such as the computer case) for several seconds. Also be
careful to handle the card by its edges and not the gold connectors.
Hardware Installation
1. Remove the computer cover. For more detailed instruction on how to perform this
step, please refer to the documentation that was included with your computer at
the time of purchase.
2. Locate an empty PCI Express slot, removing the metal bracket covering the
accompanying empty port/socket.
3. Position the card above the open PCI Express slot, ensuring that the card is properly
aligned with the slot. Insert the card rmly into the slot, distributing force evenly
across the length of the board. Once inserted, secure the card into the adjoining
socket (previously covered by metal bracket), using the correct size screw.
4. Replace the computer cover and re-connect all power to the computer.
Software Installation
1. Power on the host computer, and wait for the operating system to fully boot. Once
it does, the added card will be detected and you will be prompted to provide the
necessary drivers.
2. Insert the Driver CD that was included with PEX4S950 into the CD/DVD-ROM drive.
Please note: When installing the software for
PEX4S950, ensure that you browse to the correct
operating system folder. Allowing Windows to
search for the le may result in the incorrect le
being installed, as the Driver CD contains several
versions of the necessary software.
3. When the Found New Hardware Wizard is
displayed, please select Install from a list or
specic location (Advanced) and click Next.

Data rate tab, then click on Detect Crystal Frequency. Click OK to save this setting.

necessary components. Please do so. Once complete, a message balloon will appear
in the taskbar (normally the bottom right corner of the screen), indicating that
installation is complete:

browse to the Device Manager. To perform this step, right-click on My Computer
