[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

Hey all.

Taking a poll - how many of you are successfully using Catalina on the Designare with a >/= 4K monitor on any dedicated graphics card without any system freezing or crashing? As in, you’ve never had any issues at all.

solid here too!

rocking
a BenQ 4k monitor attached to Vega64 [via DP]
an ASUS 24" attached to R9 280x [via HDMI]

the iGPU is in headless mode

no freezes in FCPx or DaVinci
AfterFX is solid as well

@jaymonkey reported the same findings. So I'm curious to see if anyone finds a real-world application or task that benefits from the kext/SSDT.

To be fair, I did get about a 0.5-1% boost in video rendering speeds. But fans were pretty noisy overall.

Extremely solid here, I beat the snot out of this poor machine and I never have any hangs or crashes. I chuckle when I see folks who state that Catalina is finicky, or fickle, or unstable. I run Catalina on my 2013 Mac Pro, 2019 MacBook Pro and my Hackintosh and none of the three have eve so much as wiggled. I love MacOS...

4K monitors?

in your config, you mentioned Mojave. that is something I was considering trying on a spare drive. to fully replicate your setup, are you using iMac19,1?

now, one more interesting nugget. I don't want to cause NUC thread drift, but the other day after I experienced the wake failure on the Aorus, I booted my NUC8 with built-in AR which I flashed with Eliasv1 ROM. I connected the TB display and got the same results--no wake from sleep, and "no Thunderbolt devices" upon reboot using an HDMI monitor. so based on 2 data points, it is an AR phenomenon. on my list of troubleshooting steps is to flash the AR AIC with Eliasv2.

I have my SSD drive on the Aorus Pro set up to boot into either Mojave or Catalina using the same EFI folder. I just tried Catalina and Sleep/Wake worked fine for a couple cycles. However, on another attempt the Apple Display did not wake up, but the HDMI did. System Info - Thunderbolt showed the Apple Display still on the Thunderbolt bus. A reboot did not bring the AD back displaying. However, a cold boot did return it to displaying. A subsequent sleep/wake worked. Obviously no consistency.

Paraphrasing CaseySJ on this thread -- if you want a computer that just works, (most of the time?) then buy an Apple instead of messing with a hackintosh.

This is a GC-Titan Ridge AIC.

I'm using iMac19,1.

When I flashed my GC-Alpine Ridge AIC I used the GC-Alpine-Ridge-NVM-21-V3-NATA.bin ROM file in the "depository." I only used that flashed card with another build I have using a Designare mobo without a video card. I THINK I got the Apple Display working with it, but never tested sleep/wake. The AR card is now back on my shelf!

Looks like there could be a problem with the Alpine Ridge ROM you used for this application. You might want to try the ROM I used, or maybe you need to try an GC-Titan Ridge card.

Thanks. I tried for months with Catalina, could not solve my system freeze ups with a 580 or a 5700 xt on this hack. My MacBook runs fine, and so does Mojave on this hack. It’s a mystery for me so far.

 

[FormerUser-50757]

Yes, it's the Asus Designo 27" 4K connected via DisplayPort directly from 5700XT. No HDR or high refresh rate or AMD FreeSync capabilities on it.

...makes me wonder if it’s my monitors not liking Catalina. Even I put them in DP 1.1 or 1.2 mode i still get freeze ups. they don’t have any fancy DP daisy chaining features, hdr is off in the OS, and FreeSync is off. Running at 60hz I think.

Still getting some kernel Panics. I set the Catalina USB boot drive to the same Product ID as my former Mojave Z370 Aorus Gigabyte Gaming 7: iMac, 14,2. A few hours ago it would boot up with half of the log logistics that I'm showing here And then it would just go all black.. Progress maybe to a full stop of log/commands ending with ..

BSD process name corresponding to correct thread: killall
