Hi Guys,
You want better power consumption or easily overclock your cpu? This is the best way to full control over your CPU with insane speed and optimization out of the box on Skylake systems (and maybe Kaby Lake also).

What will you need? Only the latest Clover bootloader and Clover configurator app. (no extra kexts, no dsdt)

In Clover configurator edit your config.plist. Select Cpu section and clear everything (text inputs and checkboxes). Ok, settings are blank now. Then set this values:
  • HWPEnable - Check
  • UseARTFrequency - Check
  • HWPValue - ((YOUR CUSTOM CONFIG))
Custom config:

Example for OC 4.2Ghz: 0x20002A01
Green HEX: 00 - 94
(00 is the closest value for high performance, 94 is the closest value to power saving)

Red HEX: maximum frequency (multiplier)
(I using 2A (hex) = 42 (decimal) because I need OC)

Blue HEX: minimum frequency (multiplier)
(unnecessary to modify)

So,
Green hex value symbolize your performance/eco needs 00 - 94
Red hex value mean the max decimal CPU multiplier including OC/turbo (need to convert hex to decimal)

Some converted values (hex - decimal):
23 - 35 (with 100Mhz CPU Base clock = 3.5Ghz)
27 - 39 (with 100Mhz CPU Base clock = 3.9Ghz)
2A - 42 (with 100Mhz CPU Base clock = 4.2Ghz)
2B - 43 (with 100Mhz CPU Base clock = 4.3Ghz)
2C - 44 (with 100Mhz CPU Base clock = 4.4Ghz)

Converter:

If You would like to use OC, set in BIOS first.


Important note:
Some SMBIOS doesn't work. I use iMac 14,2. Maybe becoming Clover versions increase number of working platforms and stabilize this method.

I'm confused, why did you chose 20 instead of 00 for the green digits?

Because 00 is the highest level of performance. If you set this value, CPU will run on max frequency almost in a row. CPU frequency doesn't falling down to lower values just some rare cases especially idle mode.

But I start using this value 2 days ago, so I haven't too much experience with value of 20.

My advice for usings are:
00 - Video editing, Gaming (gaming on mac ?! haha)
20 - Photo editing, Graphic works
40 - Website editing, coding
60 - Office work on MacBook with power savings first
80 - Work on Battery with MacBook this is absolute power saving

I don't now yet these HEX values are the best config values or few steps are predefined like 32, 64 instead of 20, 40

Why not just overclock in BIOS and get full overclocked CPU when you need it and low usage when you don't?

Skylake HWP function help to accelerate CPU Power Management, speed steps, C-states, P-states. With HWP you can rule your "CPU Agressivity".

BIOS overclock just one thing, required to set voltages, BCLK and multipliers of course.

HWP gives instructions on how the system treats CPU resources. Like "CPU Agressivity" (green hex values), and some tweaks ex: min-max freq, speedsteps, etc. BIOS Doesn't give this instructions.

So,
  1. BIOS set resources
  2. HWP configure how to use resources
Try it! This method is a huge performance boost! :)

Please comment your experience if it works on Your Kaby Lake CPU ;)

So, on a system that is overclocked to, for example, 4.5GHz, the red 2A should be set to 2D?

Is the green section meant to override how Apple has set macOS to run and set a more aggressive SpeedStep profile?

Does having an ssdt.aml file generated by ssdtPRGen.sh affect this?

Do you have a link to more info on this setting? I'd like to read more. Thanks.

  • Yes 2D = 45 (45*100Mhz=4,5Ghz)
  • Yes, exactly
  • ssdt not needed for this config. Use this or ssdt method. Do not use two at the same time.
  • I haven't more info unfortunately, but i like read more also.

WOW ... this increases my aftereffects rendertimes alot ... awesome .. thank you so much.

offtopic. is it possible to show the OC in "about my mac"? i tried the sdtPRGen.sh script method with added "-turbo 4400" but it is not shown up. maybe i set something wrong?

I made it but I am not sure it is working. It says HWP enabled and supported but many things show disabled and unsupported. Could you please check my result is working or not?
