I tried every possible solution...the last is to use flashback BIOS. Even if yesterday I wasn't able to flashback BIOS. (Motherboard turned off, press BIOS flashback button for 3 secs and nothing happened!) Today at work, I discovered that my USB with BIOS (renamed in WSXTG.CAP) was formatted in FAT32 but has 2 EFI partitions. (I used it with Linux.) So that's why flashback didn't started. This will be the last try, and then I will ask for a new mb. RAM is in vendor list (128GB G-skill Ripjaws F4-3000C14Q2-128GVKD). Graphic card is an old GTX680, and other PCI-e cards are WiFi/BT module and USB 3 module like the one used by @izo1.
You need to format the USB flash drive as MBR (FAT32) with Disk Utility and then put the WSXTG.CAP file in the root. It works for me every time. It only doesn't work when I forget and use GUID to format the USB flash drive.
I went from 2001 to 2002 and I was not getting a video signal, then I realized once I got into the BIOS that even after clearing CMOS and applying my pre-saved .CMO file from my USB stick, the Above 4G (AUTO option) was disabled. Enabling that solved all my issues.
Honestly updating BIOS in general is not worth it at all. The only reason I personally do it because I am sick in the head and want it to be the latest. The SAGE10 notes did not say if they updated the microcode for the 10xx CPU line, so not sure what they improved. 1201 was really stable maybe stick to that?
When I don't touch the technical side of a Hackintosh for a few months, I always forget how to troubleshoot haha...
Regardless of all this, you
might have a bad mobo. I know I did with the Prime Deluxe II, Designare EX and another Prime Deluxe II. Basically this is my 4th X299 board and I'm pretty happy with it *knock on wood*....but I may end up like
@djlild7hina and just sell this whole system and get a Mac Pro when it comes out and just build a SFFPC for gaming.
I'm getting really tired of "troubleshooting" even though I really love this system and it's capabilities.
