macOS Native CPU/IGPU Power Management

For me, Intel Power Gadget (3.5.5 - newest) never shows DRAM in Power pane. Only shows PKG and CORE.

Power only shows PKG and it is not correct, too low.
See Post #1/Supported CPU/IGPU/1. Ivy Bridge/HD4000
Did you implement exactly as noted?
 
Dear toleda, yes - looking at Mac74's post - something is wrong. But I was talking about my situation - Intel Power Gadget never shows DRAM in Power pane section. Only PKG and CORE.

Hi there,

I see i7-9xxx in the list but no i9-9xxx. Does it mean that there is no need for custom ssdt with i9 series processor?

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 ?
