PCIe Lanes

[Infinisearch]

Recently I noticed that an Intel i7-6700 only has 16 pcie lanes. But motherboards have some x1 slots in addition to the x16 slot. I was wondering if you use one of the x1 slots does the x16 slot operate in x8 mode? Or are there extra PCI-e lanes from the chipset that I'm not taking into account. Also the same thing for Haswell.

There are PCIe lanes on the PCH too

Thank you kind sir. Guess I should've checked wikipedia before making the thread.

edit - BTW are those pure pcie lanes because I seem to recall something about pins being "convertible" between sata, usb, and pcie. If thats the case then a MB with alot of USB ports and SATA ports might have all the extra lanes used for that instead of pcie.

This article sheds some light on the capabilities of one of the Skylake chipsets:
