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

I sold off my Radeon VII about 3 weeks ago and made more than enough to pay for the 6900XT. Oh, and it does have a USB-C port!
Wow. Why are the prices so crazy on Radeon VIIs? I got mine new for one third of the price they're going for now.

Edit: I just looked it up. Apparently they're one of the best cards still for computational tasks (especially video) and mining.

Yeah, the 16GB of HBM2 memory makes it highly coveted for mining these days.
 
Good morning! What would be the best BIOS (Gigabyte) version at this point to use? i j k ? Or version i (modified that is in the tutorial)? Kersion k (beta)?
 
@CaseySJ

Are the issues with the latest versions of the Designare BIOS on Tweaktown problems for Windows users as well? I believe the latest versions for Aorus Master are suffering from the same issues. Just curious if these are bugs that will eventually be fixed, or if it's just a hackintosh problem that will never get addressed.

Hello @Rag,

Any one of these should be used:

I am beginning to question Gigabyte's ability to produce tested, reliable BIOS updates. Maybe they (and other board vendors too) have too many boards on the market and not enough people to support them properly.

I am perfectly happy running the Elias-modified BIOS F9i. Maybe that will be our weapon in this fight -- namely, we might grab the important parts of a new BIOS and stuff those parts into F9i! :)
 
Going on with the Antelope issues on hackintosh systems
I contacted them. The price is way too high, they offer a volume discount for 5 users. If anyone is interested in give it a try let's see if we reach the number. Sure, I don't like that much to pay for a mod but if it's the only way we must think about it.
How much they want?
 
The Gigabyte GC-Titan Ridge kinda works on the Designare Z390 but not as well as the onboard TB.

What make you think your onboard Thunderbolt chip is "hosed up"' ?
The chip to flash is just a very basic 1MB flash ROM, it's replaceable (with some tricky SMD soldering-fu). But it's very hard to brick unless you physically damage it. (But it's also possible you damaged something else on the board if not careful.)

If it doesn't boot, it may just have a corrupted firmware.
If you can't read it anymore you may just have a bad connection to it.
If you manage to have a good and stable connection to the chip, you may be able to rewrite a correct firmware and solve your issue.

What method did you use to flash the chip ?
The most reliable way is to disconnect everything on the board, take it out on the flat surface :
  • Use a 3.3V CH341A programmer or a Raspberry PI with a SOIC8 clip
  • Stabilize the Vcc rail with additional capacitance, some recommend one 47µF capacitor for the Designare, I had better results with three 10µF.
  • If it doesn't work, add two pull-up resistors (1kΩ-2kΩ) connected to /WP (to force disable write protection) and /HOLD (to force the chip in a resume state).
Here is a picture of my setup :
I used the Raspberry Pi method. I can't seem to read it anymore. It doesn't look broken. It just won't read the chip any longer. I'll try to connect again. Could be the clip.

I have found the 3.3V CH341a programmer to work in cases where even the Raspberry Pi fails. Costs between US$9 and US$14.
 
I found that DRM (Apple TV) is not any longer working with OC. Does anyone have he same issue? Whatevergreen bootargs won't work with Big Sur, right?
