eGPU with a Desktop Thunderbolt Settings (GC-TITAN-RIDGE AIC 2.0)
I would like to add my eGPU to my Windows workstation as an added rendering node for Octane and Redshift. I know it's possible but I think my issues start with my thunderbolt card that I just installed. The card shows up in my device manager, I installed the intel drivers. But it's very rare when thunderbolt recognizes a device when it's plugged in. I'm just testing with a UCB-C drive at the moment. Strange thing happens, if I put the drive into the thunderbolt card, nothing happens. If I pull it and put it into a dedicated UCB-C port it works, then I put it back into the Thunderbolt card and it finally works. So I wonder if somethings not initializing at boot?
Here are my settings on a z370 Aorus Master, I'm on a journey trying to understand what all this means. Maybe I should go buy a board with dedicated onboard Thunderbolt?
Thanks for any help on this!
@timot-mo, Which Thunderbolt 3 add-in card are you using?
@itsage, Thanks for responding!
It's the GC-titan ridge 2.0. As I understand it, It's the only Thunderbolt card approved for my board.
Just a note, unless I have GPIO3 enabled the card does not show up on boot. It'll show up only if I plug a device into it. However with GPIO3 enabled, the card shows up but generally doesn't work as far as I can see.
I'm only testing it with a usb-c drive at this point. Should I get an an actual thunderbolt 3 certified drive to test it with? I have thunderbolt 2 drive on hand.. I suppose I would need to get an adaptor..
@itsage, Wow.. no I wouldn't have imagined this. Do I need to get that cable and do this? When I get a second a take look at the card and see if those options are there.
@timot-mo, I used a short wire to jump the two pins on the included cable. Here's my Thunderbolt 3 build with a Threadripper a couple years ago. It's also possible the newer firmware in GC-TITAN-RIDGE 2.0 works differently. There's an older firmware (23) in that same build.
@itsage, Man you're pure awesome... how do you guys figure this stuff out? When I'll get a chance later today, i'll open the hood again and see we we've got and send you an updated.
Oh on a side note, in case I can't get this to work.. I was thinking about getting a Gigabyte B550 VISION D with onboard TB.. Would that be a good route to go? Of couse I'm going to have to navigate the scalpers for the 5900X.. good grief.
So the wire that plugs into the TB header splits into two types of adapter, plug.. whatever you call it. The one that's not in use.. is this the one I short.. for lack of better terms?

@timot-mo, Your motherboard has the THB_C header so no need to jump the pins. That workaround was for motherboard without the Thunderbolt header. You only use one header cable depending on the header on the board (5-pin in your case). I would say to look into the BIOS and see what Thunderbolt settings are available then try different configurations to see what works best.
@itsage, Thanks! Yeah from what I learned is that cable trick was essentially the same thing as the GPIO Force PWR option in the BIOS.
GPIO Force PWR works for me in that the card can be seen after boot. Unfortunately when I plug a device into it, nothing happens.. if I turn GPIO Force PWR off and plug a device the card initiates and works.
So basically I just need to solve whatever issue is causing it not to function even though its seen in the device manager as working.
