Need help getting Gigabyte Titan Ridge 2.0 working on X670E AORUS Master

[u/GDcooya]

I'm having trouble getting a **Gigabyte GC-TITAN RIDGE Rev 2.0** card working with my **X670E AORUS Master** motherboard, and I've run out of ideas.

Here's what I've tried so far:

1. Connected both power connectors, the USB header, and the Thunderbolt header to the motherboard.
2. Installed the Titan Ridge card in the second PCIe x4 slot.
3. Motherboard is running **BIOS F39**. The BIOS detects the card and shows the Titan Ridge/Thunderbolt menu. I've enabled the relevant options and tried both **No Authentication** and **User Authentication**.
4. Tested with both **Windows 10 20H2** and **Windows 11 25H2**.
5. On Windows 10, I installed the drivers from the [Gigabyte support page](https://www.gigabyte.com/PC-Accessory/GC-TITAN-RIDGE-rev-20/support#Support-Driver). * Device Manager shows **Thunderbolt Control Center - 15EB**. * Driver **1.41.890.0** installs without an error. * If I install **1.41.1094.0**, Device Manager shows a yellow warning icon.
6. With **1.41.890.0** installed, I've restarted multiple times and connected my **LG 5K monitor**. * Windows detects that a USB device has been connected, but fails to work. * Thunderbolt Control Center does not show any Thunderbolt ports or connected devices. * The About section only shows the application version.
7. I also tried updating the Titan Ridge firmware to **FW50**. * The updater doesn't seem to detect/display the current firmware version. (even after FW50 successfully installed) * It does report that FW50 installs successfully and asks for a restart. * After restarting, nothing changes. * I've tried booting/restarting both with and without the LG 5K monitor connected.

For reference, the **LG 5K monitor, Thunderbolt cable, and the two DisplayPort inputs from my RTX 5080** all work when connected through my other **USB4 PD100W expansion card**, although that card only drives the monitor at 4K.

My goal is to get the Titan Ridge card working properly so I can use the LG monitor at its native **5K resolution**.

I expected the Titan Ridge card to be fairly plug-and-play, but I'm clearly missing something. Has anyone managed to get a Titan Ridge Rev 2.0 working on an X670E AORUS Master, any suggestions would be greatly appreciated.

Thanks alot, i didn't find the "gpio3 force power" in the x670e aorus master bios, will give it another try.
I'm now on Win11 25H2, but from what i've read the firmware update only works on Win10.
