This system definition is not under your recommended system definition for successful dGPU Power Management
Post #1/Table 1 updated
using iMac18,2
18,2 is the 21" version, fewer CPU options
18,3 is the 27" version, more CPU options; recommended
after setting in headless mode, do I still need to setting for discrete GPU Power Management according to your guide?
Yes
what is the recommended system definition for a headless mode system like I have?
Not relevant, only the installed CPU matters.
any specific thing I need to give attention
Everything, attachments on this thread show neither CPU PM or GPU PM is working

I have a quick question. I am running High Serria with a i9-9900k and gtx 1080. Since a i9 9900k belongs to the iMac19,2 definition, and a gtx 1080 has no related definition, its not possible for me to acheive native discrete GPU power management right? Thanks

I have a Gtx 1080 on a skylake system (17,1) and successfully made the kext, but it seems to not affect performance at all.

No files attached.
My apologies, I wasn’t asking for help, just stating that in my case, (Asus Rog Strix GTX1080) I saw no performance difference with gpu power management successfully enabled (benchmarks, thermals, and acoustic performance remained the same)

How did you determine "gpu power management successfully enabled?"
by verifying IOReg/AGPM/Nvidia/Heuristic-ID: 4 (nvidia) and using the machine for a month while noting the acoustic, thermal, and overall smoothness of the system... if there are other ways to see if the performance has changed, I'll try those too (my day to day work does not push the 1080 to it's max though, and I don't game in OSX)

Not what the screenshot shows.
IOReg screenshots are useless and a total waste of time.
I apologize for attaching it then...
