Please try these changes:
  • BIOS --> Internal Graphics --> enabled.
    • If this is set to "auto" it will turn off IGPU when discrete GPU is detected and driving a display monitor.
  • In Devices -> Properties, click the bottom (3rd) entry in the Devices list box. Then look at the Properties list box to its right. You should see ig-platform-id
  • In Boot --> Arguments, change shikigva to 16 or 80. If you watch Netflix, change it to 80.
  • Then run VideoProc and check if HEVC and H.264 hardware acceleration is enabled.
OK, changed the internal graphics to enabled.
In Devices - properties ig-platform id was set as 0300983E. I changed it to 0x3E980003 - value type: data, but upon reboot that had changed to 003E9800 03. Is this a hex code thing?
I set boot arguments to shikigva80. This now allows me to view Netflix in Safari which is a huge plus!! I was forced to use Chrome for Netflix previously.
Unfortunately videoproc still reports hevc hardware acceleration unavailable.

Oh no, I didn't say to change ig-platform-id, but only to check whether it exists. Platform ID is specified in reverse byte order so the original value was the correct value: 0300983E. Please change it back to this, reboot, and check again!

Yes!!! Switched it back and ran videoproc and it now says hevc hardware acceleration is enabled! You rock!!! Thanks again @CaseySJ! I don't know what I'd do without you!

Please see the spoiler in Post #1 State of the System AFTER Post-Installation:

Regarding flashing guides, please refer again to Post #1, the spoiler Mini-Guides for Flashing SPI ROM Chips. All of those guides should be read, but these two in particular may be most suited to the Designare Z390:

If you have any questions during the procedure, just ask. But please understand the risks and disclaimers!
Thanks. I’ll keep you posted.
You scared me a bit with your disclaimer. How many users succeeded the flash or failed / bricked?

No errors / logs suggests a hardware problem. If you are using an XMP profile for the ram try disabling that and see if your stability is better. I had a similar issue and tweaking the ram settings cleared it up.
Yes, I’m also thinking the same thing. It’s been months of troubleshooting now. With both the old RAM and the new RAM, I’ve tried XMP on and off without any changes.

My problem is that I’m running out of hardware to check or replace. Haha. Ripping out the MoBo or the PSU is going to be what I try last I guess. Do you, or does anyone else’s think it might be a faulty motherboard? I’m not familiar with a bad motherboard‘s symptoms.

The power supply seems fine - No Noises, booting or shutdowns or error lights anywhere...

The only real thing I can say is that the lockups happen when working with audio or video apps, and usually happen after 5-6 hours of working. Heat doesn’t appear to be the issue though Unfortunately.

So far one person may have damaged their Winbond chip, but that person has plenty of soldering/desoldering skills and is in the process of replacing the chip. That happened before @jb007 developed the procedure referenced in the last of the SPI flashing guides. I've flashed my board two or three times without issue, as have a number of others.

I would be irresponsible if I didn't point out the risks.

Hello, Casey!. I was one of your first to follow your guide. The hackintosh still works as a beast :)

But I am getting mad to install Windows on a new separate SSD. When I try to run a bootable Windows pen drive, it gives me an error during the installation blue screen ..looks like it is missing some drivers when i try to create a win boot using commands method...and if i try unetbootin i got stuck on blue screen installation with error 0x8007000D... can I know what you did to have 2 different OS on 2 different hard drives. I have your same hardware ..Thank you so much

I have flashed my Alpine Ridge with modified Titian firmware at the start just because. Then back to the original, then to another modified, and I think at least one other time. A few times it failed to write. I just adjusted the clip and tried again till the flash stuck. I flashed my Titian Ridge to the 23 and 42 versions of the modified Titan firmware and finally settled on the Designare mod'ed firmware. I think it is 33. “I did this against Casey’s advisement”. So I have done at least 6 flashes on two cards. Both cards still work. I think, as long as you have a programmer, your fairly safe even if it fails the first three or four times take a deep breath and keep plugging along.

Hi @CaseySJ and @EliM.

I have the iGPU running in headless mode using ig-platform-id=0x3E980003 in Clover 5107.

I'm using shikigva=16 and could not run Netflix on Safari, but the Brave browser based on the Chrome engine will play if I load the Widevine extension.

Setting shikigva=80 allows Netflix in Safari (my prefered browser) but then Sidecar which I tend to watch Netflix in, connects but black screens. One step forward, one backwards.

Any idea how to fix this would be very welcome.
