i also wonder regarding your titanridge-flash, has things gotten more stable regarding hotplug and to be able to boot without any devices connected etc, while still maintain hotplug? Or is it just benefitial for certain tb-devices and cosmetic in systemreport?

i ordered the usb programmer stated in this small guide:

What firmware did you use?

Refer to CaseySJ’s thread for thunderbolt flashing and success stories. NVM33 appears to work best for Titan Ridge
 
The bios v3101 have some major problems regardless if using the patched bios or their Asus original version :) It's just buggy, here is why:

1. The machine not posting (blocked on the red led), after multiple resets, it will start.
2. Even if it starts and it greens the MB light, no display will work trough DP only via HDMI.
3. OC will not detect the audio (internal soundcard) with this bios.

The advantage in my case for having bios 3101 it is clear, using cascade CPU the 10980XE has a dramatic shift in the CPU performance versus bios 2002, as highlighted in post #810

I've emailed Asus with a long report email requesting a fix for Bios 3101 as MSR Lock is not working as well as the post-failure and the GPU signal errors. Hopefully, they are already working on an update and this will come handy for them.

For now, I will stick to bios v 2002 as everything works with this including the audio, SolarFlare, the CPU (lower readings than normal for now).

The only things I need to sort out with the OpenCore for now:
1. Thunderbolt trough flashing as in this link: https://www.tonymacx86.com/threads/...olt-3-i7-9700k-amd-rx-580.267551/post-2095044
I've ordered the 'CH341A Programmer' from Amazon so they should be with me tomorrow. Will report if successful

2. There are some lags when the login screen first comes up and when the screen comes back from the screensaver.
Anyone experiencing these problems?


@djlild7hina What's the SSDT used with your flashed Titan Ridge? Is it the one you included in post #812? KPG's or that one are not currently working under OC. I found that SolarFlare had the fix by disabling integrity protection and copying on the library kext as on a normal mac as per post #19, copying the kext in the EFI folder would crash, that used to work under Clover. I'm thinking maybe after the TB flashing this should just come up with no SSDT?

Not experiencing those issues on BIOS 3101 and audio works here.
Titan Ridge SSDT from CaseySJs thread as I mentioned before. KGPs SSDT is used for nonflashed cards.

Thanks! Do you still have the tb-header connected after this flash?
would be interesting to know if it’s possible to have multiple titan-ridge cards, even in an asus environment :)

Yes it’s possible, no I don’t. Don’t even need tb bios settings enabled, just need to jump pins 3 and 5 on the header as mentioned in the tutorial.

wow, thats really interesting, regarding bios settings. Feel pretty dumb now cause everything is probably already stated, but it’s Too many posts in that thread and i don’t find it that organized. But maybe i’m Just used to kgp’s super documentation with chapters etc:lol:
Thanks again! Cheers

Yes tons of posts in Caseys thread but he has important posts referenced with the tutorials and files in the first post :)
 
A question for OC users and Gigabyte Titan Ridge pci-e card on Sage 10G....are you able to work with thunderbolt ? I tried with OC but my thunderbolt peripherals are not recognized, even if i put tb3ssdt inside. Everything is ok with Clover but no way to have thunderbolt with OC

Does it show that it’s properly loaded in pci and ioreg?
