OK so I should start with ASUS X299 SUPPORT
Thanks for starting the thread. I added information to post 3 with pretty much the info from post 1 here. Also added links to previous threads and thunderbolt patching information.

I am still having trouble with crashes and random reboots on my X299 Sage 10G Catalina OpenCore system. I was running it with (not overclocked) 64 GB of 2400 mhz memory, which is way under the speed it will accept. The memory checked out fine with MemTest, so I decided to go ahead and upgrade the memory to see if that might help. So I got Corsair Dominator Platinum RGB Memory, 64GB running rated at 3466mhz. I installed it without making any changes to my BIOS settings. When I installed it, it booted up through to the BIOS Setup, where it immediately complained of the CPU having a 99 degree Celsius temperature (overheating). Then, I guessed it crossed the 100 edge mark and shutdown. This memory, I just noticed, shows to be compatible with the X299 Sage 10G in the 3200mhz and the 3600mhz speeds. Is the 3466 MHz speed causing my overheats? Is there a BIOS setting that could help?

Here’s what some of the bios settings look like if that helps (these are the original settings when I have the 2400 MHz memory):

I was having somewhat similar problems. Turning off "Turbo Mode" for the Cpu seemed to help. So far I've been using my hack for weeks without any crashes when it used to occur sometimes multiple times a day.

Thanks, @Loloflatsix. I was able to get the RAM to work and to get past the BIOS without overheating. Still having the random kernel panics and reboots. I will start a post on the X299 Big Sur Support thread...
