It does say TB3 supported on the box and in the description on the web, but no BIOS to allow TB hmm
So if you have a port for thunder bolt header that the card's cable plugs into I'm assuming it should be fine. All of the motherboards use the same Bios wether or not you have thunderbolt card installed. There is a separate firmware for the card itself that may need to be installed but you would have to have a real old version of the card. I've used F3, F5 and F6 motherboard BIOS without any problem.
The bios settings are things like "port security": Here is a basic starting point I used....I think I ended up changing one or two more (I can look today. If you have the gaming 7 I can just upload my bios):
BIOS Settings
1 Save & Exit → Load Optimized Defaults
2 M.I.T. → Advanced Memory Settings Extreme Memory Profile(X.M.P.) : Profile1
3 BIOS → Fast Boot : Disabled
4 BIOS → LAN PXE Boot Option ROM : Disabled
5 BIOS → Storage Boot Option Control : UEFI
6 Peripherals → Trusted Computing → Security Device Support : Disable
7 Peripherals → Network Stack Configuration → Network Stack : Disabled
8 Peripherals → USB Configuration → Legacy USB Support : Auto
9 Peripherals → USB Configuration → XHCI Hand-off : Enabled
10 Chipset → Vt-d : Disabled
11 Chipset → Wake on LAN Enable : Disabled
12 Chipset → IOAPIC 24-119 Entries : Enabled
Download the drivers (and update utility) in windows and see if you see the device:
