I just took a look at my saved searches that only look in Canada (no import taxes and free or $20-$30 express shipping…
Look what just popped and he’s open to talk ?? If I had waited to order my RX 6600… it’s not taxable so basically 140$ more than the RX 6600 for almost twice the power ?‍♂️ Someone go buy it… my bank converted it at $548 USD ? 515 €
I bought for a little over $2500 of hardware with the used Mac Pro 6,1 the 12 cores and 64Gb memory kit, Razer Core X, 2 GC-Titan Ridge V2 cards, TB3 cables, 2 Apple TB3 <-> TB2 converters, the RX 580 I got 2 months ago and RX 6600. I need to take a break before the next GPU ? take it away guys ???
Wow, that's the second best VEGA card that you can install on a MacPro5,1, 16GB HBM2 is the fastest VRAM that you can have bar none.

Cheaper than a RX 5700.

Has anybody ever had success running a TB2 Falcon Ridge card in the cMP5,1 ?
I have one of these lying around here, I guess it is from HP or Dell and should use the same chipset as the MacPro6,1.

It would be a perfect fit for my UA Apollo with TB1 port, which won't work with TB3 chipsets (not even on real TB3 Macs), but works with the 6,1.

I once tried the card (Slot 4) but nothing was detected, but didn't try to bridge the header. I guess I would need to flash some kind of MacPro6,1 Firmware on it.

Any thoughts on this?

Thanks!
 
Looks like he is working again…
Read that it is dsm2 but not sure if it’s true.

Another recent possibility for better compatibility with Thunderbolt 4 devices:

Looks like NVM67 firmware. I'm assuming we can flash this to our Titan Ridge 2.0 PCIe cards?

Correct. It should also work on version 1 cards. We've had good luck with the previous version of this firmware (NVM33 for the Designare Z390 motherboard), so we may actually see some improvements here. On the other hand, previous updates to the GC-TITAN RIDGE (NVM43 and 50) have been regressions (broken xHCI) and actual Mac firmware has left much to be desired (only one port functional). I haven't done any testing yet because I've been busy with something more interesting...

I have both versions of the GC-TITAN RIDGE. I'm looking into externally resetting the main PD controller on wake to avoid power cycling my LG UltraFine 5K.
Proper reconnect on wake is another shortcoming, but I believe this one can be addressed with a hardware modification, which I am currently investigating.
I've successfully interacted with the PD controller and fixed the UltraFine no-wake issue! Since the display now works just like on a supported Mac, I suspect that Apple does something similar for proper Sx entry and exit flow (if only I had some schematics...). I'm now designing a small PCB for the card. Very exciting!

I wonder if this hardware modification would be useful in general. Do other Thunderbolt devices have wake issues? If so, I may design the hardware for wider adoption.

Are you going to make multiple pcbs? :)

So would it also fix the need to restart display to enable things like usb hub and having to unplug and plug display from cold boot?

Maybe but it’s not modified… didn’t test it since I put all my efforts in maple ridge, but I send everything Titan Ridge related to CaseySJ… Everything I could share…

Yes, fabrication houses typically make a minimum quantity. I'm thinking that it will be a very small board that connects to the card's 5-pin header. The PCB will provide the logic, but a few modifications to the card will be necessary to make it all work.

I haven't really faced these issues with my setup, so it's difficult to say. My display turns on by itself once macOS has loaded, even on cold boots. And on warm boots, it shows the bootscreen and has functional USB ports as well as brightness and volume controls. Almost everything already works very reliably. Before my fix, the only power cycling that I needed to do was after wake-from-sleep.

I believe that the key to having an image on cold boot is the order of the DisplayPort cables. In my case, the cables cross each other: the left-most port on my RX 580 (installed in my Mac Pro) is connected to the right-most port (port 1) on the GC-TITAN RIDGE.

Actually, you can find the modified version here:


It has the ARC system turned off and the external connection manager turned on. Those are the necessary modifications for Mac. It also includes modified configuration straps.

I saw the Titan Ridge datasheet that you posted over there. I'm sure they'll find it useful. It was actually posted here on MacRumors a few weeks ago. I found the Alpine Ridge datasheet (which you originally provided—many thanks!) to be much more useful for understanding Apple-related settings. It seems that they stripped some details (particularly, key chicken bits). I suppose Maple Ridge is even worse, given that Apple never adopted it. Good luck with your project: I'm really looking forward to it! :)
 
I'd return the RX 6600 and buy the VEGA FE, it's even better than a Radeon Pro WX9100, with a faster HBM2 VRAM and really mature macOS drivers.
Looking at this ad:

And used card I am almost 90% sure it was used for mining.
 
For those wondering: Z390 NVM67 breaks USB 3.x for the GC-TITAN RIDGE in the classic Mac Pro (just like versions 43 and 50 for the card).

I have tried severals firmware the one is working with is V23 Elias and Apple Firmware from Installer in USBC Monterey but to make the two thunderbolt ports working both is a nightmare !!! So one in daisy chain
 
Could someone please modify the TB3 SSDT or show me how I need to mod it so that I can use my PCIe USB 3 card in slot 3?

When I install my Sonnet USB3 PCIe card into slot 3 my TB3 card disappears but when I remove it, the TB3 card works.

My config is

Slot 4: Titan Ridge 2.0 TB3 Card
Slot 3: Sonnet USB3.2 Type-C PCIe Card
Slot 2: Startech PCIe Dual NVMe Card
Slot 1: RX 5700 XT GPU

If there's truly no way to fix it then I'll just sell it and leave as is. I got it with the mac pro, but was hoping to get it working. Seems I have a similar problem as someone else did here and they edited the aml file to fix it.

you will have to look at the ioregistry explorer and make a note of the path changes (with and without sonnet card)
