M.2 and U.2 Slot Breakdown

PCI-E Lane Distribution (44 Lane SKX CPU's)
U.2 1 – Gen3, x4 lanes from CPU (No Shared Lanes)
U.2 2 – Gen3, x4 lanes from CPU (No Shared Lanes)
M.2 Key-M (110mm) – x4 CPU lanes (No Shared Lanes)
M.2 Key-M (80mm) – x4 PCH lanes (No Shared Lanes) (*)
M.2 Key-E (32mm) – x1 PCH lane (No Shared Lanes)
PCI-E Lane Distribution (28 Lane SKX CPU's)
U.2 1 – Not functional with a 28/16 lane processor.
U.2 2 – Not functional with a 28/16 lane processor.
M.2 Key-M (110mm) – x4 CPU lanes (No Shared Lanes)
M.2 Key-M (80mm) – x4 PCH lanes (No Shared Lanes) (*)
M.2 Key-E (32mm) – x1 PCH lane (No Shared Lanes)
PCI-E Lane Distribution (16 Lane KBX CPU's)
U.2 1 – Not functional with a 28/16 lane processor.
U.2 2 – Not functional with a 28/16 lane processor.
M.2 Key-M (110mm) – x4 CPU lanes (Gen3, x4 shared with PE5)
M.2 Key-M (80mm) – x4 PCH lanes (*)
M.2 Key-E (32mm) – x1 PCH lane
All M.2 Key-M slots on this board support PCI-E, NVMe, and SATA M.2
•
standards.
o (*) If a SATA M.2 drive is used in the 80mm M.2 the SATA 0/1 will be
disabled.
This motherboard does NOT have any lane replication via PLX; all lanes are
•
native and derived from CPU or PCH. This also allows for improved backwards
compatibility for Gen 2 devices.
