I would not use the USBInstantWake.kext

Some shots in the dark if you wanna try...
When it's black screen can you hear your sound effects? The computer is still working just without display?
Try with a single monitor HDMI and try all the ports.
Try unplugging the monitor's HDMI/dvi cable and back in.
I was actually meaning I tried using the USBWakeFixup.kext and Rename. Sorry about that. When the screen is black I don't hear any sounds. Also, I tried unplugging and replugging with no avail.

I tried running the command pmset -g log | grep -e "Sleep.*due to" -e "Wake.*due to" and got my results. It didn't show any wake. So I assuming my computer is not actually waking at all. All the fans start like it's going to but that's when the monitors start up and go black.

@mtcollins05 that doesn't look right at all, some of those options I think are for laptops, what SMBIOS are you using to get those settings? But before you do anything else, reset your monitor's energy settings. See if that does anything.

These are my settings, maybe you can figure out how to disable some of those other settings

I'm running out of ideas, other than BIOS settings.
In your BIOS is there an option to turn off serial port? Disable your iGPU if you haven't already.

YOU ARE THE MAN!!!!! Serial Port Disable fixed it! I was regretting switching from Clover for the last couple weeks but you were able to help me fix my NVRAM and Sleep which were my only issues.

Thanks so much for you help!

Yes linked in the guide for other methods you can follow if you don't have flashback on your mobo.
I tried both mate.. Seems like AI SUITE II and my mobo doesn't want to take the modified version of my bios firmware.. I think with the mobo it have to do with my usb flash drive so i bought a new one to test it out.. With the AI SUITE II, it successfully flashes the original firmware but not the modded version.. I just managed to do the transplant method, i took my ssd out of my system and connected it to a mac book pro, did the install that way. Everything works..
I have one question though.. If i still use the latest bios firmware with no native nvram support, will i have the same problems with big sur updates in the future?

Damn you did the transplant. Yea I'm pretty certain your gonna need nvram for increment updates too. i think it has to do with Apple's new snapshot features.

I got someone confirmed with your same board that flashed it fine through USB flashback on another forum.
Make sure you follow your motherboard's instructions for using USB Flashback, correct USB port, correct USB format, etc. You're doing something wrong there.

Do you know what older bios version they used to compile with 3503? that information would be really good for me to know
