I have been doing research and decided to buy the titan ridge thunderbolt card. I installed it in my slot 4 as instructed and connected the pci connectors to the psu and the usb to a open usb header on the MB. My MB does not have the thb_c header and I read I do not even need that as long as I have my thunderbolt 3 device attached before booting. 

When I boot my 16tb OWC Raid bay light turns blue to show its connected but not showing up as a device, same as before I had this card installed. I downloaded the thunderbolt 3 software and installed the gigabyte driver disk that came with it and updated my bios. The thunderbolt does not show up under tools in my bios either. I am stumped and not sure what to do and it is driving me crazy.

What does Intel Thunderbolt Software show when you have a device connected at boot? If you didn't jump pin-3 and 5, you may have to restart the computer for Thunderbolt device to be properly detected.

Nothing shows connected at boot. The light on my bay goes from orange to blue on boot so I know its "connected" but when windows comes up and I log in it just shows up as "thunderbay 4" under my eject list but not in thunderbolt software and the drive is no accessible. It essentially does the same thing it did before I got the titan reader minus the error message of "this thunderbolt device may have limited connection"

I also do not know how to jump pins or what that means

Keep in mind using an AMD board is definitely not a supported Thunderbolt configuration. It's not a certainty the Titan Ridge Thunderbolt 3 AIC would work with your particular motherboard. I had success adding this AIC to an ASRock X399M Taichi and the details are in this thread. You can see how pin 3 and 5 can be jumped in this post

Instead of jumping the pins directly on the AIC, I shorted out the corresponding pins on the THB-C header cable connector. The red piece is a wire I used to connect pin 3 and 5 together. Here's a closeup photo of that short red wire. I don't use Power Delivery or USB 2 so those three other plugs are left vacant.
