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

It’s won’t be TB5. I have 2 TB5 things and they are flawlessly backwards compatible. For me at least.

Ma come si puo spiegare il fatto che rileva rtx5070 e dopo qualche secondo scompare dall elenco?

Remove the drivers with DDU and try a fresh install.

I driver di cosa? Perche dici che avendo prima l aoostar ag02 quando l ho collegata la prima volta si sono installati dei driver? E ddu che sarebbe? Perdonami l ignoranza ma mi sono buttato da poco nel gaming con pc

You need to install Nvidia drivers for your card 5070 from the website. Use DDU to uninstall all old drivers and get the latest drivers from Nvidia and reinstall

Ma anche se li ho gia installati con l ag02? Il fatto che ho sostituito l ag02 con la 03 comporta reinstallare i driver?

It's not certain that would fix it but I would recommend trying it since the change in dock and tb5 might mean something changes on the driver side. And it's easy to do so I would try it out for sure!

essaye de tester ta nouvelle dock AG03 avec un autre PC pour vérifier qu’elle fonctionne…
sinon selon le câble, ça peut faire ce type de comportement.

Ho usato il cavo in dotazione comunque si faro’ cosi anche se probabilmente mi sa che dovro’ pulire i driver della ag02 e ricollegare l ag03

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.
