2018 AMD X399 Threadripper 1950X [R1K,16C,X] + RTX 2080 @ 32Gbps-TB3 (Razer Core X) + Win10 [itsage]
Thank you very much itage I will buy the GC-ALPINE-RIDGE and that procedure I would have to do the same with the pins or the normal contact of the header in their respective place, I would follow in the bios f10 to designate mobo or I have to do test and error
@brian_salazar, You don't need to connect the header cable to the GC-ALPINE-RIDGE AIC. It doesn't work as a Thunderbolt 3 add-in for the motherboard. It simply converts DisplayPort stream/s to Thunderbolt 3 monitor output.
@brian_salazar, It's likely to do with power state of the computer. I have not tried monitor output to Thunderbolt 3 then to Thunderbolt through an adapter. Have you tried connecting the THB_C header on your X399 Designare EX motherboard?
what do you mean by computer power state?
if i tried with the tb head connected and disconnected, thunderbolt display had already been working I really don't know what happened, any bios settings? I have bios 10 modified by wendell, I just need to try pin 3 and 5 as if it were gc titan. I have changed the pci ports and nothing has worked for me yet I also installed different thunderbolt drivers and nothing
Could you show my bios settings?
Do you think the gc alpine ridge card has been damaged?
@brian_salazar, does the x399 Designare have a Thunderbolt header? If not, then you may want to connect the Force Power and Platform Sequence Control pins to 3.3V using 8.2kΩ pull up resistors.
Then in the EFI Shell, if the "pci" command doesn't show the GC-ALPINE RIDGE (8086:1578), then find it using the mm command. The bus number will be one that is not listed by the pci command. The four bytes at register 4 will be not FFFFFFFF for a device that exists. The four bytes at register 0 will be FFFFFFFF for hidden or non-existant devices.
For example, for bus 09, enter:
mm 090000004 -w 4 -pcie -n
If it's not FFFFFFFF, then it means there's probably a PCIe device there.
A Thunderbolt controller will have 0x1234 at offset 0x502:
mm 090000502 -w 2 -pcie -n
You might be able to enable USB with these commands (using bus 9 for example):
mm 09000054C 00 -w 1 -PCIE -n
mm 09000054C 0D -w 1 -PCIE -n
Reading the byte at 548 should give the result 0x0D:
mm 090000548 -w 1 -PCIE -n
@joevt, thanks for helping but it is too complicated for me what you are saying, the mobo x399 designate has tbheader but the following I did not understand how to do it
I want use just for Windows
I know this is an old thread but just wanted to stop by and send thanks to itsage and everyone else for all their work in proving TB3 functioning in Threadripper systems with the Titan Ridge card. Never would have guessed I'd ever need it. I did several days of research and read through most of the linked threads relating to Thunderbolt 3 and eGPUs here and finally jumped in, purchased a card from eBay that arrived today and got it going with no fuss.
Only reason I really went with it was because I also have an Asrock x399m Taichi board with 2950X and a few 2080 Ti cards that I didn't want to go to waste/re-sell and utilize for rendering purposes instead. Strange, I would have never considered that as an option or use for eGPU and not really sure how I got here but I'm glad it's going to be usable! Anyways, I'm still waiting for the Razer Core box to arrive but the card appears to be detected as expected in HWINFO, as you've shown in the pictures in the beginning.
Not sure how I post a picture (I'm a new user, maybe it's limited to x amount of posts) but will be back to report the final outcome, though I'm expecting success based on everything I've read and am seeing on my end thus far. Not sure I'll ever expand beyond the 2 external enclosures but if I do, how exactly would I daisy chain these Razer enclosures beyond 2 or is that actually possible with this sort of setup?
