I finally solved the problem of the second sleep!

It worked for me, I used this from
@casstsai " i disable Above 4G Decoding in my BIOS, and add npci=0x2000 boot-args,the second sleep issue disappear"
I could not disable on Z790 AERO G, to be able to boot add npci=0x2000 boot-args (no issue WiFi after wake), fast sleep and wake up again without problems. I tested with several sleeps in a row..
- Opencor 0.8.8
- ResizeGPUBars = -1
- ResizeAppleGPUBars=-1
- Bios F4K
- Above 4G Decoding - DISABLE
- Above 4GB MMIO BIOS assignment - DISABLE
- Internal Graphics - ENABLE (strange, if disable wakes up immediately after sleep, maybe only for K processor versions)
Thanks!
