There are 4 PCI Express slots on this motherboard.

PCIE slots: PCIE1 (PCIE 3.0 x16 slot) is used for PCI Express x16 lane width

graphics cards, or to install PCI Express graphics cards to support

CrossFireX

PCIE2 (PCIE 2.0 x1 slot) is used for a PCI Express x1 lane width card,

such as a Gigabit LAN card or SATA2 card, etc.

PCIE3 (PCIE 2.0 x16 slot) is used for PCI Express x1 lane width graph-

ics cards.

PCIE4 (PCIE 2.0 x16 slot) is used for PCI Express x4 lane width graph-

ics cards, or to install PCI Express graphics cards to support CrossFi-

reX

function. And for installing ASRock Game Blaster.

1. In single VGA card mode, it is recommended to install a PCI Express

x16 graphics card on PCIE1 slot.

2. In CrossFireX

mode, please install the PCI Express x16 graphics

cards on PCIE1 and PCIE4 slots. Therefore, PCIE1 will work at x16

bandwidth, while PCIE4 works at x4 bandwidth.

3. Please connect a chassis fan to the motherboard’s chassis fan

connector (CHA_FAN1 or CHA_FAN2) when using multiple

graphics cards for better thermal environment.
