x1 and x4 PCI Express Support
PCI Express x1 and x4 is supported with the same PCB. This add-in PCB is designed to work in both types of
motherboard slots. The PCB complies with the width and length dimensions of the PCI Express Card Electrome-
chanical (CEM) Specification Revision 1.1. The only exclusion of the CEM specification is the component and back
side of the add-in board may interfere with other boards in a fully-populated motherboard.
This board is easily interchanged from x1 to x4 configurations by removing the back-panel bracket and reinstalling
it on the opposite side. This permits plug-in into PCI Express sockets on the motherboard and securing it in the
chassis if desired. The back-panel bracket is shown below.
