8 Slot Connectors (PCIe, miniPCIe)
PCIe Connectors 8.1
KTQM87 supports 1 xPCIe x16 (16-lane) PCI Express port, 2 x miniPCI Express with different options, one
miniPCI Express ports (J14) with mSATA,USB2.0 and SIM-card Socket (J15) one miniPCI Express port (J13)
with mSATA and USB2.0. The PCIex16 slot supports PEG Bifurcation 2x PCIex8 or 1x PCIe x8 + 2x PCIe x4,
but need Riser Card with bifurcation functionality to work.
The 16-lane (x16) PCI Express (J8) (PCIe 2.0 and PCIe 3.0) port can be used for external PCI Express cards
inclusive graphics card. Maximum theoretical bandwidth using 16 lanes is 16 GB/s.
