I7 4790K PCIe Lanes – CPUs, Motherboards, and Memory – Linus Tech Tips

Hi, I have a I7 4790K and a Gigibyte Z97 Gaming GT with 4 PCI 3.0 x16 slots that are able to run all at the same time in x8 mode.   I’m kind of newbie with PCIe lanes.   How can the CPU with 16 lanes support 32 lanes plus any PCIe x1 slots.   Also, how can if it’s using another chip-set to get additional lanes, how to I check to make sure that my GPUs are using the CPU lanes.
