Confirmed. 0x514 = 1300
Hi
My last built is a GA Z390 Designare with i9-9900K(non oc) because of the hardware I set the system as iMac 19,1.
I can confirm that the CPU lower state is @1,3ghz.
Power management/sleep/usb seems to work fine.
Multicore Geekbench score 38600.
Can anyone with real iMac 19,1/19.2 confirm the same idle clock speed?

Hi @toleda,
See that line in my AppleIntelInfo output :
IA32_PM_ENABLE...................(0x770) : 0x1 (HWP Supported and Enabled)

Also have X86PlatformPlugin loaded - What is PM in that case : OS or hardware ?

  1. My CPU freq gets higher than it should be, it should be 3300 Hz at max, but I see 3400 Hz. Computer reboots when CPU works for too long with this frequency - in a few seconds after Spotlight indexing starts.
  2. My config is 10.15/Asrock H61m-VG3/i5-2500k/Saphire Radeon RX 570 Nitro+
  3. I installed ssdt_xcpm.aml with PluginType=YES
Everything worked fine on Sierra. I guess I need to limit CPU frequency somehow.


Added:
sysctl -n machdep.xcpm.mode returns 0, does it make any sense?
