0x777 should be real time status, not really know in what condition it will active, since it never change during all HWP (XCPM_HWP, Clover_ HWP) tests.Done, max frequency from Intel gadget 3.6Ghz , so at this point BIOS settings aren't the problem right?
MSR_TURBO_RATIO_LIMIT............(0x1AD) : 0x27272727 ------------------------------------------ - Maximum Ratio Limit for C01.......... : 27 (3900 MHz) - Maximum Ratio Limit for C02.......... : 27 (3900 MHz) - Maximum Ratio Limit for C03.......... : 27 (3900 MHz) - Maximum Ratio Limit for C04.......... : 27 (3900 MHz)

Does HWP_STATUS value is correct even if it's enabled?
IA32_PM_ENABLE...................(0x770) : 0x1 (HWP Supported and Enabled)
Clover HWP method (seems to be real HWP control) only 0x770 MSR_IA32_HWP_ENABLE registered to kernel and does not need XCPM control, after HWP enabled CPU PM handled by CPU which refer to ACPI HWP tables, 0x774 MSR_IA32_PM_VALUE is option for optimise power level.
For detail of ACPI HWP tables, press F4 at Clover boot menu, then read DumpLog.txt, my mobo HWP tables are Cpu0Hwp, ApHwp, HwpLvt.
Apple HWP (should be a advance XCPM control) is slightly different, HWP request and ARTFrequency are sent through XCPM, HWP features also mixed with XCPM features.
If Clover HWP is incompatible with your HACK, then use CPUFriend method.
