This will be fixed once I send a Thunderbolt SSDT with custom DROM (soon).So, the results. Good news: all these firmwares enabled TB Bus on 3-TR and GC-TR.
Speed is shown as "Up to 20Gb/s x2" instead of expected "Up to 40Gb/s x1"
This is what I like to see!In depth
When holding the card vertically with the PCI pins facing the floor, are the top and middle pins of the 5-pin J1 header bridged? Don't worry about pin numbers, which are confusing. Just hold vertically and bridge the top and middle pins.- If nothing is connected to AIC, the TB Bus won't be enabled, i. e. "No hardware was found" in the TB section. Valid for both cards.
These are all unfortunately well known problems with add-in-cards. They work best after a warm reboot. No known solutions at this time...- If UltraFine is connected on cold boot, TB Bus will be enabled on 3-TR. GC-TR won't enable it until you re-plug UltraFine after the boot.
- No UltraFine's internal devices are recognized on cold boot even if TB Bus is enabled. You won't see them in Camera and USB sections until you reboot the machine.
- Same things in Windows, but you won't get internal devices working after reboot. You need to boot to macOS first.
- No bootscreen on cold boot with UltraFine at all. You may get it after booting to macOS, i. e. on warm boot.
I even got an old Apple Thunderbolt Display working with that mod!
3-TR looks more stable with all that stuff, maybe because it's compatible with my motherboard. Flashing card also means that you lose boot screen on UltraFine, unfortunately.
This will be fixed with SSDT.@CaseySJ I'm bit concerned about TB speed, why it shows 2x 20 Gb/s links instead of single 40 Gb/s? Could it be fixed anyhow with another fw modification?
