This motherboard comes with on-board LEDs that light up when the PCIE/
PCI devices are not correctly installed. This is a reminder that you should
reinstall these devices. Refer to the figure on the right for the location of the
LEDs.
• The PCIEx16_1 slot (blue)
supports PCIE x16 cards
only. The AI Slot Detector
lights up when you install a
x1 or x4 card to this slot.
• When the AI Slot Detector
lights up for incorrect
installation, make sure to
shut down the power supply
unit before reinstalling the
card to avoid electrical shock
hazard.
Primary PCI Express x16 slots
The primary PCI Express x16 slots support PCI Express x16 graphic cards that
comply with the PCI Express specifications.

This motherboard also supports a Universal PCI Express slot with a maximum
speed of 2 GB/s. The operating frequency of this slot changes, depending on the

If you install two VGA cards, we recommend that you plug the rear chassis fan cable
to the motherboard connector labeled CHA_FAN1 for better thermal environment.
