I am adding a M.2 SSd, and my asus manual says"when the M.2_2 Socket3 is operating in PCIEX4 mode, SATA port SATA6G_56 will be disabled." I do not see a SATA6G_56, but there is a 5 and a 6. Are they telling me both SATA ports will be disabled? If this is the case, I will not be able to use that socket, and will have to run M.2 in SATA mode in a different socket, as I have 5 of the 6 available SATA ports being used.....
