Help!!! Dell Latitude 7400 2-in-1 cannot work with Akitio Node+GIGABYTE GTX 1070
I don’t know where I did wrong. When I connected Node to my Dell Latitude 7400 2-in-1, the Thunderbolt Control Center (UWP version of the control program) or Intel Thunderbolt Software showed that I have connected to the device(the Node). In the program's 'detail', my NVM version is 40.00, and the control center says my laptop can support external GPU. However, the system did not detect the GTX 1070 like a normal PC and didn't start to install the driver either---nothing happened after just hearing the prompt sound of the new device connection. Device Manager didn't show I've connected my eGPU.
BTW, my laptop's configuration:
CPU: i7-8665U with vPro
IGPU: UHD 620
RAM: DDR3 16GB
Thunderbolt ports: Double full speed ports with PD, 4 lanes PCIe, eGPU ready(At least the Control Centre said that it support eGPU)
OS version: Windows 10 Home Chinese Edition V2004
All the drivers are latest, I have tried to uninstall and install Thunderbolt drivers several times. However, I found that I can update the Node's firmware by the official tool(Does it means the connection between laptop and Node is fine?). In Settings, there are 2 new devices have shown--PCI to PCI Bridge and Base System Device. I've tried to adjust the security level from SL1 to SL0 and enable Thunderbolt Boot(Thunderbolt device pre-boot before system start) in BIOS, but there is no difference compared with my first connection.
I am really anxious about this issue, can anyone help me?
Thanks in advance
Have you downloaded the latest NVIDIA driver and tried to install it? The first thing the installer normally does is to search for a compatible GPU in your system. May be would find your GTX card and proceed to the driver installation...
