I cleaned the ME region of the bios, the machine connected with old MacOS, went up with osx LION , before the machine tava with catalina.from the outside the machine is still slow.
The voltage PPbus_g3h continues with 8.4V.
-->How do I know that the ME region was cleaned ?
-->Was it to change the PPbus_g3h voltage?

Yes, I extracted the hex file, BIOS bin from the board, opened the intel inject ME, put the compatible software, deleted the bios and recorded this new file.
