3.6 PCI-Express connectors
The KTGM45/mITX supports one (x16) (16-lane) PCI Express port and one miniPCI Express port.
KTGM45/Flex and KTGM45/ATXE supports one PCIe x16 port and one PCIe x1 port (in a x16 connector).
The 16-lane (x16) PCI Express (PCIe 2.0) port can be used for external PCI Express graphics card. It is
located nearest the CPU. Maximum theoretical bandwidth using 16 lanes is 16 GB/s.
The PCI Express (x16) interface is multiplexed with the SDVO ports and TMDS ports.
The miniPCIe (PCIe 1.1) (KTGM45/mITX only) is located on the backside of the board.
Supports PCI Express GEN1 frequency of 1.25 GHz (supports 2.5 Gbit/s in each direction, 500 MB/s totally).
The 1-lane (x1) PCI Express (PCIe 1.1) port (KTGM45/Flex and KTGM45/ATXE only) is mechanically a x16
port and electrically a x1 port. It is located farthest away from CPU. Supports PCI Express GEN1 frequency
of 1.25 GHz (supports 2.5 Gbit/s in each direction, 500 MB/s totally).
