I am wondering if you came across a way the related eprom in could be dumped....
I have a MBP 2018 here on my desk and could give any non destructive solution a try.
Thanks! I did read your post, I wanted to check if others have been having issues. I'd like to drive a thunderbolt monitor from the motherboard and making sure that was possible is on my list. I'm looking to use the i9-9960X.
Post #2,246 summaries all issues and findings obtained with @AsEvil , @Maywitt and @applemacosxGOD. I do not use a Deluxe II myself for good reason. izo1 did not use onboard TB of the Deluxe II so far and he also employed the LG38UC99, which does not have any TB port. Despite the issues summarised in post 2,246, the Deluxe II systems are stable. Up to now nobody confirmed confirmed along my X299 threads compatibility of the Deluxe II with the i9-9960X though based on the current Deluxe II BIOS firmware implementation. There have been issues with the i9-9920X and i9-9820X in any case.
A TB monitor like the LG5K2K should work in principle with the onboard TTR controller of the Deluxe II. However as for now there is no TB HotPlug, it might be also impossible to HotPlug the TB display and one would also need to confirm the sleep/wake functionality of the latter.
I hope this answers your questions.
Well it seems that the onboard Aquantia 10Gbps LAN also does not work OoB with macOS. However, as it is also an Aquantia AQC-107 chipset like the one used by the ASUS XG-C100C Aquantia AQTION AQC107 10-GBit PCIe x4 NIC , the 10.13.3 firmware update workaround and subsequent kernel patch for the latter might also work for the primer. However up to now this has not been confirmed by anybody. Also nobody so far confirmed full compatibility with the GC-TTR for this board including TB and USB-C HotPlug or sleep/wake with TB devices connected during sleep and wake.
Why I recommend the ASUS WS X299 Sage 10G is simply the fact that it's full GC-Titan Ridge compatibility including TB and USB-C HotPlug and sleep wake as well as success with the Ubuntu EEPROM modding of the onboard Intel X550-AT2 10G chipset described in Section E.8.2.2) for the Intel X450-T1 have been repeatedly confirmed by various users and @djlild7hina also provides his appreciated help and support for this board.
With the X299 Prime-A you might encounter the same wake problem like on the Prime X299 Deluxe with TB devices connected to the GC-Titan Ridge during sleep although TB and USB-C HotPlug else might work also flawless. In this case you could use one to of two AQTION AQC107 10-GBit PCIe x4 NICs, which are OoB natively implemented under macOS.
Anyway, your decision, my friend.
late here.. off to bed soon.
Very interesting. The problem with the WS line is mostly related to poor-VRM performance and heatsink, which becomes a problem especially with the latest generation i9s. Between the Prime Deluxe II and the Extreme Omega there is the lack of TB3 on the Omega, which might not be a bad thing given that I can just plug my current 4K monitor directly into the card instead of going the TB3 route.
The other thing to think about TB3 is that it's now an open standard, USB4, which is going (in a few years) to be commoditized and we might see PCI-E add-in cards supporting TB3/USB4 without the need of the header. It's going to be an interesting year I think.
