Quick Guide to Generate a SSDT for CPU Power Management

[ekwipt]

_________________________________________________________________

I have the I7-6800k processor and I tried to generate a SSDT but it failed. I am trying to install Sierra 10.12.5, but I am not sure how to generate the correct SSDT. I tried a combination of MacPro6,1 and a board ID, but the ssdt script said my processor wouldn't work for the MacPro6,1.

What are the correct options/flags that I should choose when generating a SSDT using Piker's script?
I also see that you have listed information about the i7-6800k, is there something that I can do with it?

Thank You

I can't remember sorry

Newer CPUs require the beta branch.

I think it is necessary to change the first tutorial to connect, there are beate version out of the new cpu support so that a lot of people do not go wrong

I tried this method and got a good result last weekweek. The value is from (8) 10 .... 36 (37).
But, I just reinstall OS yesterday and now I have a differrent result. The value is always from (8) 18 ... 36 (37)

Last week result:

What am I doing wrong?

Nothing. Results are the same. Only difference is the amount of time allowed for sampling and the tasks performed while sampling. AppleIntelInfo.kext collects random samples. Longer duration of collection will result in higher chance of seeing more pstates.

I tried every 10-15 minute, it shows the same result but it's still different than last week. I don't open any thing except terminal.

Completely dependent on length of monitoring and the tasks you perform with the computer while monitoring.
Missing pstates in the middle are not indicative of any problem.

For some reason my compiled SSDT.aml gives me CPU multipliers that are far too low (image attached to post).

Anyway ideas on how to basically double all my multipliers LOL?
