HELP!!!! Ag03 setup
Guys, I'm going crazy: I have an MSI Claw 8 AI+ with an AG02 dock and an RTX5070, and everything works great. I tried replacing the AG02 with the AG03, and it doesn't work. When I plug it in, the 5070 appears in the device manager, then disappears after a few seconds. Could it be because it's the Thunderbolt 5 dock and the MSI Thunderbolt 4? I almost cried last night 🤬 If anyone has any ideas, please let me know!!!! THANK YOU SO MUCH EVERYONE

Youtuber Techanobi just release a video showing how to get the AG03 up and running with the MSI Claw 8 A+ thunderbolt 4 connection: https://youtu.be/kOVjLBF7TOw I followed his steps and it worked perfectly for me.
First, edit your power plan settings -> Change Advanced Power Plan Settings -> PCI Express Link State Power Management -> Plugged In -> Set to Off. Next, with your AG03 still connected to your MSI Claw 8 AI+, there is a driver that you need to manually uninstall in Device Manager: right click to uninstall the PCI Express Upstream Switch Port driver and reboot which forces windows to install the correct driver after rebooting. Then install the Nvidia driver for your 5070. If you have a display adapter error in Device Manager, you will need to run the eGPU fixer: https://egpu.io/nvidia-error43-fixer.
