I have trouble running both Ultra M2 Port on my x99 Taichi.
I got a Samsung 960 Pro running a while on M2_2 without any problems. Now I got an new Samsung 970 Pro and have installed it to M2_1 port, but the drive wont be recognized.
When I switch them, the Samsung 970 is recognized on M2_2 but the Samsung 960 is not recognized on M2_1.
In other words... none of the drives are working on M2_1 but both are working on M2_2.

got it... my i7-6800k has only 28 lanes.

I guess I need a PCIe - m.2 adapter, which is more reasonable than switching the CPU to a 40 lanes i7-6850k
