Hello!
First time posting around here so I hope I’m at the right place, feel free to point a different thread or missing info in my request !
I’ve been fighting with my titan ridge for the past 3 weeks to get video a thunderbolt video output to my apple cinema display (thunderbolt version).
The screen is indeed recognised as a thunderbolt device after reboot (camera, usb dock and speakers work) but I have no video.
Some info about my setup:
- Mac Pro 5,1 late 2010, 96 Gb of ram, 2 TB nvme startup disk (2 1TB partitions)
- Mac flashed GTX 680 2gb (which outputs video fine tough all of its ports)
- TR 2.0
- Card Installed in slot 4
- Flashed using (I think) all of the available firmware I was able to put my hands on, but I understand the most common is the TitanRidgeMacOSFirmware.bin
- With a jumper cable between the pins 3 and 5 (the TR 2.0 has an extra connector tho, maybe the pins are different for TR and TR 2.0?)
- Osx Big Sur with Latest Martin Lo OpenCore package (0.9.4). Config modified to correct the multi monitors bug (specific to Big Sur) and to activate the thunderbolt devices.
From my online research, no video output seems to be caused by a bad flash of the blue chip. Hence I tried flashing with different osx versions / computers, with two different programmer boards (no 3.3v mods on them tho) and using windows (using AsProgrammer).
Whenever I flash I manually read the flashed contents of the chip and compare them to the bin file uploaded to make sure the contents of the EEPROM are successfully written.
Would anyone have suggestions on things I might have forgotten along the way?
I’ll happily provide further information about my setup if needed!
Thanks for all the info in the thread, it helped immensly
Thanks,
Gio
