Gigabyte Z77X-UD5H & GTX 1050: black screen after sleep

[coscos]

I have read almost all posts regarding this topic on this forum, but still couldn't get sleep work properly. So looking for help here.

Specs:

Motherboard: Gigabyte Z77x-UD5H
BIOS: F16j
CPU: Ivy Bridge i5-3570K CPU @ 3.40GHz (quad core)
Graphics: Nvidia GTX 1050
Monitor: Dell P2715Q @ 4k / 60Hz, Display Port
Wifi / Bluetooth: BCM94360CS with PCIE
Onboard GPU: disabled
OS: High Sierra 10.13.3

Symptom:

1. If I click the "sleep" menu manually, the system goes to sleep fine. After the system sleeps for a while (more than a few mins), when I try to wake it up, the monitor wakes up and after a while it goes back to sleep due to no signal. The machine is on.

2. If I leave the system to time out and sleep by itself, only the monitor goes off; when I try to wake it up, same symptom as above.

What I have tried (but none worked):

1. additional boot flag: ngfxpatch=pikera
2. additional boot flag: darkwake = 0
3. Customize EDID

Please see attached for following files:

1. EFI zip file (most of my SSDT patches are copied from this repository: https://github.com/VoiletDragon/Z77X-UD5H-Clover-Hotpatch-Patches)
2. ioreg dump
3. result from following command:

kextstat|grep -y acpiplat
kextstat|grep -y appleintelcpu
kextstat|grep -y applelpc
kextstat|grep -y applehda
sudo touch /System/Library/Extensions && sudo kextcache -u /

I am looking forward to your suggestions. Thanks.

Hi, I had the exact same problem with my other-halve's custo-mac with the same motherboard and an nvidia 1060 card.

The systemd definition was an iMac 11,1 and I changed this to a 13,2 and it resolved the issue. Maybe this will work for you too?

I ended up using a RX560. Everything works perfectly.

I'm using RX570. My system was fine until I installed some apps. Now, only the display sleeps and can't be waken up again!

I really regret building hackintosh! Too much hassle :/

If you back up your system often, plus the EFI folder, it should always be able to go back. Plus, I don't think a regular app could mess up your system. Sleep is a fragile thing, even in native OSX system. Check out some of the posts on this forum regarding sleep issues. Also check out my post here.

Good luck!
