Disable ACPI APIC in BIOS without reinstalling Windows?

[PandaBear270]

Hello. This thread is related to my previous post:
http://www.tomshardware.co.uk/answers/id-1926843/amd-throttling-starting-make-feel-hopeless.html
But to have things ordered, I want to ask this precise question in another thread.
After some research and testing, and considering these are the only power options left to try in my BIOS, I would like to test if I still getting the same drops after deactivate both ACPI 2.0 and ACPI APIC in the BIOS. The problem is that Windows 7 won't boot. I am willing to reinstall it if that makes it work and finish the frequency drop, but I need to know if is reliable to do and if there is any way to avoid a complete reinstall of the OS?
I appreciate any tips or ideas.

Referring to your original post, what is the actual problem? The graphs you posted pictures of look normal. Your chip is designed to dynamically clock up and down from a target base frequency. It's only supposed to run at the base frequency under load, and when lightly loaded, it will clock higher to what is called a boost frequency when certain internal metrics permit, and when unloaded or idle, it will simply clock down to reduce power consumption and temperature of the chip.

Even with Cool and Quiet, and turbo core disabled?

I don't see why you would possibly want to disable those, but to each their own. If power management functions are not correctly disabled, you will get throttling. Your throttling looks and sounds normal.
