then use the 1st m.2 socket

then use the 1st m.2 socket

just for my curiosity what does this mean in the manual. " The M.2_2 socket shares PCIe clock with PCIe x1_1. When PCIe x1_1 or PCIe x1_3 is occupied, the M.2_2 socket can only support SATA mode. " im confused as to what it exactly means

it mean if you have a for example sound card on pcie x1_1 or pciex1_3, you will not able to run a pcie type m.2 on m.2_2
