[Problem] Coffeelake mod Z170A ACPI Issue

Dear forum! I would like to ask for help regarding the CoffeeLake mod. This is my first attempt, and the hardware is still kind of a “prototype” for me. I put an i3-8350K CPU into an MSI Z170A PC MATE motherboard. I had to download the second most recent BIOS from the MSI support page, because the latest one didn’t work with the mod. Now it works: microcodes added, ACPI, ME, VGPU updated, etc. (Read, and flashed with CH341A, and NeoProgrammer tools). But when power management is enabled in BIOS (EIST, C1E, etc.), the system freezes on the Windows boot screen, it gets stuck, reset button works only. When these power management functions are turned off, the system runs flawlessly at 4GHz non-stop. The CPU doesn’t support Turbo Boost, so it cannot be the problem. I read that even though the ACPI table is updated in CoffeeTime 0.99, the 100/200 series chipset won’t handle the 8/9-gen CPU properly, so I would need to transfer the ACPI and other relevant components from a 300-series board BIOS (e.g., MSI Z370-A PRO) that control CPU power management. Is it possible that this CoffeeTime-modding-thing is just a half-solution? This seems a bit complicated for me at the moment. I have found a few entries in MSI Z370-A PRO BIOS file about this with BIOS modification software, but I’m not exactly sure what needs to be transferred, and how. Is it possible that I will face the same issue with my Z270 Gaming M7 board? I would appreciate any help. Thanks in advance. Regards, Bengio.
