Give me ioregistry copy so I can see.

So:

the first try is never good. Less than without. (64000 without and 60k)
Sleep/wake

And 70k, 72k, 74k.

But my second screen stuck off after the wake.

With the banned R*****B****.kext I could reach 83500 (but it is so weird...)

Try again this SSDT.

Can you also check power consumption when its at idle? Fans turn on/ off?
