OMG ! SOLVED, sorry my fault !

I forgot to inject the maximum CoreFrequency in Bios ...
Don´t know why, but for some reason I thought there is no need
to do this when overclocking with SSDT.
... sorry for that mistake ;-P
Now iv´e set it to 4200 MHz,
used "~/ssdtPRGen.sh -c 2 -t 77 -turbo 4200 -target 1 -x 0"
and it works like it should!

Thank You anyway !

Any chance you could post your config.plist. I have the exact same setup.

@mediabox007, please update your profile (personal details) with your Motherboard or Make/Model, CPU and Graphics Card.
If you have multiple systems add them to your signature or build signature.

Profiles need to contain at least your primary system to assist others with helping you.

How and where did you inject that max CoreFrequency? Some Clover key?

 

[drwhy]

... no,
you have to enter first Bios (by pressing "delete" at startup)
and set the corefrequency to 4200MHz.

save & reboot

OK! Learned ..
So the OCed ssdt setting, turbo is set higher in ssdt, ONLY doesnt make any OC.
We must also set the higher multiplieres (for base & that 1,2,3,4 unser load cores multiplier) in the bios.
