M.2 and U.2 Slot Breakdown
PCI-E Lane Distribution
U.2 – x4 PCH lanes
M.2 Key-M (80mm) – x4 PCH lanes (Optane/PCI-E/NVMe/SATA)
M.2 Key-E (32mm) – x1 PCH lane
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.
