Imposible to install drivers for SER8 8754HS AMD Radeon 780M Graphic card

manudas

Hi
So I have a SER8 8745HS and I have a big problem with the Radeon 780M in Windows 11. I cannot make it work or install the drivers.

Doesn’t matter what I do, it doesn’t work. I installed AMD drivers and at the end I got a message from AMD software telling that even though the installation was successful, windows reported a problem with the device. This is the device in Device Manager:

You see here error 43 but I also saw error 31.

Before I tried to update the driver the device showed up as deactivated.

Can anybody help?

After investigating:
I installed 96 GB Ram in the Minipc, it recognise them all in Windows.
However, when both of them are installed, the Graphic card fails to initialise (and it shows that weird error in the Windows Device Manager). Doesn’t matter which of the modules is removed, so that means that no module itself is broke, as I can remove any of them for the Windows to be able to start the driver of the Radeon 780M.

Doesn’t make any sense… In the webpage I read that even till 256GB are supported. If the problem were the amount, not even windows would have booted.

The memory are Crucial 5600MT 46CL if I am not wrong.

Anybody can help ?

I installed back the memory kit that came with the computer (32GB Ram) and after manually enabling the graphic driver it worked! However if it boots into windows, it is clear that the issue is not the 96Gb Ram, I think.

Would it be a Bios issue?
This is my serial number:

And this is my Bios version:

Can anybody support me, please?
