My opinion after having to ask is
Forget a first phase the small as > Sleep
Make focus on correct operation of the computer - processor
In all my build are not using DSDT and SSDT and using nullcpu.and fakecpuid
i m on latest bios with copy and the reserved bios (asrock function)
I have sent you a link to p.m .. used.
After that just play with your bios to find the right mix.
Even today I do not know if it is the perfect way
but certainly the operational mode, and I am very happy with it and the stability of the computer.
I hope to help you.
