• We recommend that you install a VGA card on the primary (blue) PCI Express slot and install any other PCI Express device on the secondary (black) PCI Express slot.

In CrossFire™ mode, install the ATI CrossFire™ Edition (Master) graphics card on the primary (blue) PCI Express slot; otherwise, the system will not boot.

If you do not configure the PCI Express device (s) according to the table below, the system may have a failed or delayed power-on self test (POST).

Refer to the table below for possible PCI Express Card configurations.
