Aero 15 HQ7700 low TB3 bandwidth issue
That's too bad about your timing. To be honest, had it not for you and others to raise issues with the PCIe 2.0 x4 root port implementation in the old BIOS I doubt Gigabyte would have rolled out the update this quickly.
I'm can confirm that after flash BIOS ver FB09, PCI-E #5 show the correct version(3.0).
but I do not have any e-GPU to test PCIE bandwidth lol.
Pending: Add my system information and expected eGPU configuration to my signature to give context to my posts
