M.2 socket 3

ThissocketallowsyoutoinstallanM.2(NGFF)SSDmodule.

• ThissocketsupportsMKeyand2242/2260/2280storage

devices.

• WhenadeviceinSATAmodeisinstalledontheM.2

socket,SATAport1isdisabled.

WhenusingPCIcardsonsharedslots,ensurethatthedriverssupport“ShareIRQ”orthat

thecardsdonotneedIRQassignments.Otherwise,conictswillarisebetweenthetwoPCI

groups,makingthesystemunstableandthecardinoperable.
