    PCIe lane distribution on Strix X299-X(E) mobo?

    Pardon me if this has been asked before, but are either of the two M.2 slots on the X299X/XE Gaming motherboard routed straight to the CPU, or do they both go via the chipset? Any documentation etc I've read has been unclear, or not said anything about it.

    don't worry about PCIe lanes if you have a cpu with 44 Number of PCI Express Lanes

    if your cpu is less then i worry

    No, they both go through the PCH controller. Only the extreme with DIMM.2 has one of them that can be set for CPU of PCH
