Cool seeing so many people having SLI Kingpins! Im currently Non-K OCing with SLI KPE 3090s. Very fun! Have you guys updated your bios since this post? Which works best with SLI? Im currently on 1.15 and cant seem to get x16 4.0 for both with 2 GEN 4 cables. Cant be the lanes right? Im disabling the M.2 slots.
You got your answer in another thread, but just in case someone pops in 6 years from now, the Z series of motherboards do not support 32 PCI lanes, so users will never get above x8/x8 on a Z series board, unless Intel starts including more pci lanes in the future.
There is only 16 dedicated lanes between the two PCIe x16 slots (physical length, not wired length). Slot 1 can get 16 lanes without a device in slot 2. Any device in slot two reduces slot one to x8, even if it is a single x1 device.
