Odd problem here. When I run cinebench CPU test, the speed of the CPU ramps up to ~2600 mhz. Once the temp of ~70 C hits (typically within 5-10 seconds), the CPU throttles down to 1200-1400mhz and stays there. Temperatures will fall down to 60 C and CPU speed and temp will remain at that level until the stress test is done.
However, if I load windows and perform a stress test, the temperatures will remain around ~70 C and the CPU will speed will range from 2200 mhz - 2600 mhz.
Only if go back into Mac after doing the stress test in windows, the CPU will perform just like how it did in windows (maintains max CPU speed at around 70 C). If I perform a reboot after the stress test in Mac, the CPU will maintain max CPU speed at around 70C. If I perform a shutdown in Mac and relaunch cinebench after booting into Mac, the CPU problem reappears. I haven't found a way to get the CPU to behave normally without having to boot into windows prior.
Not sure what to make of this, but problem reporting files are attached. Thanks in advance for any help and guidance. I'm very close to getting a stable hackintosh if it wasn't for this problem!
Things I've tried:
1. Both methods outlined in the following guide:

2. ssdtPRGen - I know this isn't necessary for high Sierra, but wanted to see if PM would behave any differently
3. Various CPU parameters in config.plist. Setting min multiplier, C3 latency to 0x3E9. Neither of which made a difference.
