I'm sorry, I mistakenly think that I am using HD6670 because HD7650a is not in this list, so I introduced the first thread for reference of connection method.
I think the fact that there is an MXM Card that can be used with HP8300/8200/8100/8000 itself is a nice news for USDT users.
I am not...
It is a comment to me because of the comment link, but this post is for you.
ssd.aml is mainly required for the performance of the graphic board, but if there is no dissatisfaction with the display, there should be no problem in operation without using it.
What kind of graphic board are you using?

It was good that you could solve it yourself.
It seems that the time has come to select SMBIOS from similar GPUs instead of selecting SMBIOS from similar CPUs.
I am confused because the phenomenon that occurs depends on the GPU used.
The attached ssd.aml is used by SMBIOS=iMac13.2 Mojave.
ssdtPRGen.sh seems to work (create) normally.
However, I have no idea what caused it not to work.
I have commented on the phenomenon that it does not work on RX570/580, so please refer here and try it...
I think it is the specifications of RX570.
The fan will rotate when the power is turned on or when the temperature exceeds 60 degrees.
As for what I was trying to do, I was trying to follow the guide below with SMBIOS=Macmini6.1...
