X79 Turbo Rev 6.0 (PLEXHD) -- Cheap Chinese X79 board that can freely change Vcore after simple BIOS modifications

@Lost_N_BIOS , [mention]Lost_N_BIOS[/mention],



Overall goal with what I am trying to do: Access the ICC overclocking in BIOS, but I am getting the same error message as in this thread.

What I have done initially
-Unlocked menus through AMIBCP 4.53 by setting them to "USER" (Advanced/Intel ICC which then re-directs to Advanced/Enabled)
-Added a second ICC profile (using the Overclocking template) in Intel FIT. This guide helped a lot

But still I cannot change anything in BIOS (same error message when going into "Intel ICC", freezing when I select a profile), or using Intel XTU. As I understand it, this is because ME is disabled in this BIOS. What I have done further to enable ME:
-Tried updating to the latest 9.0.x and 9.1.x 1.5Mb ME update. The system can run with either one, but still no access to ICC
-Dumped the IFR to text and searched for relevant strings
-Manually checked in AMIBCP if there is anything I have missed
-Ran me_cleaner on a complete SPI dump to verify that the AltMeDisable bit is not set

Am I on the right track? Is there some advice you can give me? If you need it, BIOS can be found in this post. It seems that ME is disabled in most/all of these Chinese boards
