Hi folks,

Does anyone works on a Gigabyte x299 Desinare Ex?

Not yet, but no reason for it not to work, see post #1 , #2 , #3 as a starting point

Hi folks,

You can also try my EFI if you want, #72 , confirmed working by @netzu on X299 Aorus Master.
However @Loloflatsix posts & EFI should work on your system.

Hello all. Would anyone be able to assist me with the random boots I am having with Catalina. On the introductory screen (country, apple id and etc.), the system will shut down and reboot. I have no clue why. If anyone could provide a cause it would be greatly appreciated. Much thanks in advance.

Thx guys for your update.
I have a question about MB configuration. I looked at Gigabyte settings and ... in M.I.T/Advanced Frequency Settings/Advanced CPU Core settings I have for Intel Turbo boost Max Technology 3.0 Native Mode or Legacy not Enabled/Disabled. I had a look on google but it's only talking about drivers installation in legacy mode

If I ask this question, I ran geekbench on my build on windows 10 and the system froze completely. When I boot, I had an error message "The system has experienced a boot failure possibly due to incorrect configuration. Previous settings in BIOS may not be compatible with current hardware state.

Current CPU Speed: 4501,4 MHz
Current BCLK: 100.2MHz
Current Memory Speed: 2133.82MHz"

EDIT: i tried to set to AUTO "Enhanced Multi-Core Performance" and no more crash under windows...
I'll try under macos

@Loloflatsix post #1 tells you exactly the bios settings to apply on your Mobo.
Re: Intel Turbo boost Max Technology needs to be enabled.

You can also engage the XMP profile for your memory settings. Your freezes/crashes are most likely due to your overclocking parameters. You need to start with lower settings ( 40/41 ) and run a few Cinebench or Geekbench tests starting from there. If it passes , you can up the overclocking settings by a single digit at a time. Obviously you'll need a decent AIO Cooler or custom Cooler to reach higher CPU speed. You'll reach lower thermal ceiling with an Air Cooler.

The overclocking settings in Gigabyte are very tricky and more complex than Asus. They put bunch of security/safety settings that will Freeze, shut down and even reset/break your bios if you do not know what you are doing. It took me a while to learn & understand all of them before tweaking them. Patience is an absolute requirement. I also recommend to save regularly your Bios settings on a USB Key, so you access them quickly in case you'll get a Bios reset during this process.

@hkuser :
I checked your EFI :
- MacProMemoryNotificationDisabler.kext not needed with iMacPro 1,1 SMBIOS (on your config.plist)
- You must perform your own USB.kext and SSDT-UIAC.aml with Hackintool and remove USBInjectall.kext
- add your required SSDT according to your IOReg
- also check your bios settings see post #1
- after boot completed your can attach your IOReg for help

@Ellybz : sorry but I omitted to point your EFI on post #72 on the resources post #2 I will edit now

@Ellybz I read that Intel Turbo boost Max Technology needs to be enabled but ... my mobo does not have that choice. Only native or Legacy
The parameter Enhanced Multi-core Performance is for activating overclocking? I do not want to overclock now, only use stock perf but in performance mode, not lazy

You do not have this function??? ( screenshot below from my previous Mobo, GA Aorus Gaming 7 )
Line before Turbo Ratio (1-Core Active )
I even have it on my Wu-8.
