Anyone try any m.2 riser on the z370-a board?   I bought some of m.2 with USB plug only not the one with 1x pcie bus on it, it seem the board is not seeing the gpu.  also i did try on the z370-p board, same thing happen.
the GPU fan run full speed when power on but nothing happen, i also did change the bio to x2 speed and set to pcie only not auto.  I only try to setup with 1 gpu that connect to the m.2 riser.
i was thinking m.2 is bad, but i open up 4 of them all doing the same thing.

anyone have successful with m.2 on 370-a or 370-p board please let me know which m.2 you got.
thanks.
