So, you are soure on 100% that thunderbold 3 has 2 lanes? Is any laptop database where i can write this information?

 100% sure - your Elitebook 840 G6 has a 2-lane TB3 controller with a reduced 16Gbps maximum PCIe bandwidth. A 4-lane TB3 controller has a 22Gbps maximum PCIe bandwidth. See measured bandwidth comparison of 16Gbps-TB3 (2-lane) and 32Gbps-TB3 (4-lane) at:


We database by denoting a build using this system as having 16Gbps-TB3 bandwidth at:
