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

If it helps, here are some photos.

Thanks! @bugsyraz Since the missing component is directly between 3.3V and pin 7 i would assume that this might be the same resistor value as the one between 3.3V and pin 3 (which would make sense). This one is 3.3kOhm. (In fact I think all the resistors connected directly to the pins of the chip are 3.3kOhms.) I don’t think that this has any other function than drop the voltage at the pins a bit more perhaps? If so it should work fine without the resistor anyway, because as far as I understand it the chip can handle up to 3.6V.
Anyway, I have bridged pin 7 and 8 now and … tadaaa:

At last! Congratulations, those screenshots are picture perfect!

OpenCore Mini-Guide has been updated for OC 0.5.7.

If you run VideoProc --> Setting --> Options, and you notice that H.264 and/or HEVC is not enabled (see screenshot), try downloading the attached dummy141.kext zip, copy the unzipped kext to /Library/Extensions and run Kext Utilility to rebuild kernel cache.

Reboot and run VideoProc once again to determine whether H.264 and HEVC are both operational.

Hai @CaseySJ ,
I ran this VideoProc app and in the settings its showing Intel UHD630 desktop series graphics as name in the graphics section(not my RX580)....and the H.264 and HEVC hardware accelerations are enabled. How can i know if my RX 580 is getting used properly for graphics purposes?.
Added dummy141.kext to L/E.
Also headless configuration is enabled.

Short Question: why suddenly is native nvram and unlock msr register in bios needed updating from mojave to catalina?

It's always the little things!

I was about to post my photos...but no need now!

Congratulations!

And that makes it all worth it...

Eh, who cares.

What is the make/model of your Thunderbolt 1 Hard Drive? Did it work before flashing the firmware? If it is working only now, then I'll add it to the new list of Thunderbolt devices.

Thanks, Casey!

The make/model of the HDD is Pegasus R4. This is their first version on TB1.

This wasn't working before at all, neither in OSX or on Windows.

So glad to see someone else fixing the same problem. I bet there were more people that had the same issue.
Congratulations!

Hey there,

Is there a way to find the thunderbolt host controller's unique UUID (not UID) for the Z390 Designare?

I think that all the controllers on mac pro 7,1 are connected to CPU lanes and probablly all have the same firmware but yes lets see about that. i'll try to do a live linux boot and extract the firmwares. g\ If the first two or three firmware files are the same then of course we can stop there!

@CaseySJ OK ! all ASPM BIOS settings are OFF state .. then have you still, under IORegExplorer, pci-aspm-default property under RP05 to NHI0, with non-zero value ? If still different from Zero, I should directly change this incorrect state under related register. Yes -- unfortunately they still...

So I now have the iGPU showing up in iStat, Both Vega cards appear in the SystemProfiler, Premiere (yuck) and Cinema see both Vega cards but apparently I am stalled at addressing the iGPU. FCP won't render h.264 and Resolve will not launch. And in a probably unrelated issue, my Gigabyte boot...

To make life more complicated.

Native NVRAM is the way to go. Our aim is to make this build as reasonably close to a real Mac as possible. The NVRAM guide explains some of the specific reasons why we should do this.
