7 Slot Connectors (PCIe, miniPCIe, PCI)
7.1 PCIe Connectors
All members of the KTQM77 family supports one (x16) (16-lane) PCI Express port, one x1 PCI Express
port and two miniPCI Express ports.
The 16-lane (x16) PCI Express (PCIe 2.0 and PCIe 3.0) port can be used for external PCI Express
cards inclusive graphics card. It is located nearest the CPU. Maximum theoretical bandwidth using 16
lanes is 16 GB/s. PCIe x1, PCIe x2, PCIe x4, PCIe x8 and PCIe x16 are supported; however PCIe x2 is
only supported when using 3rd generation Intel® Core™ processor (Ivy Bridge).
The two miniPCIe (PCIe 2.0) is located on the backside of the board.
The 1-lane (x1) PCI Express (PCIe 2.0) can be used for any PCIex1 cards inclusive “Riser PCIex1 to
PCI Dual flexible card“.
