Hello Everyone,

I have a Predator PH315-54, which has a NVIDIA RTX 3060 with an Intel i5-11400H.

Is it normal that my GPU's PCIe v4.0 x16 lane only reaches a rate of x8 instead of x16 under full GPU load?

    Thats normal, the GPU has been given 8 lanes of PCI4 on this model :) the number of lanes has to be pre-assigned and cant change on the fly as they come off the CPU, but 8X is more than enough bandwidth for the GPU!
