" rel="nofollow - I have a 40 lane CPU (i7 6800K) and Taichi Motherboard. I understand the limitatations of the processor mean that one of M.2 Ultra slots (M_1) will function in SATA mode. But WHICH of the slots is M_1, and which is M_2? The board layout in the Taichi manual does not indicate which one is which... ------------- A well regulated Militia, being necessary to the security of a free State... |

And I just realized / noticed....... M2_2 supports 22110 "length cards, so that would make: M2_1 the one next to PCIE1 M2_2 the one between PCIE4 and PCIE5 HTH |

Mistyped owing to regretful/wishful thinking on my part. The 6800K is 28 lanes. I took a lucky guess that the M.2 slots would be numbered like the PCI, lowest to highest from the "top" of the board. Higher number would be between 3/5, as you said, but thanks for the help. The BIOS config browser also shows where it is as well, but you've gotta be booted (obviously) at that point. ------------- A well regulated Militia, being necessary to the security of a free State... |
