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 CrossFireXTM function.

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- reXTM 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 CrossFireXTM 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.

4.Only PCIE1 slot supports Gen 3 speed. To run the PCI Express in Gen 3 speed, please install an Ivy Bridge CPU. If you install a Sandy Bridge CPU, the PCI Express will run only at PCI Express Gen 2 speed.
