HP Z6 G4 Workstation - Alpine Ridge DP based TBT3 PCIe add-in-card

HP Recommended
HP Z6 G4
Microsoft Windows 10 (64-bit)

According to the following 2 links the HP Z6 G4 Workstations should now support a Thunderbolt 3 add-in card.


The recommended Alpine Ridge DP based TBT3 PCIe add-in-card ( does not appear to work.


Is there a recommended Thunderbolt 3 pcie add-in card HP recommends for the Z6 G4 Workstation?

installing thunderbolt cards is a tricky process, and if you skip/miss one step the card will be non functional


first remove the TBolt card, and then uninstall the software (start from a clean system)


now, reboot and install the  HP TBolt software if you don't have it stop and get it without it you can't proceed


once the HP TBolt software is installed, power off and install the TBolt card (install it only in the HP specified slot) then connect the HP TBolt cable from the card to the motherboard again, no cable = non working card


power off and attach the video passthrough cable from your video card to the TBolt card


power on, enter bios TBolt option should now be seen (if not power off and restart at begining)


in the Bolt bios options select which Northbridge pci-e slot the card is in and also set enable/force  GPIO 3 power on

setting the GPIO 3 to on will make the card show even if no TBolt devices are attached to the card


you might also have a enable USB 3.1 port option, if so turn it on


reboot and run the TBolt program from the start menu, the card should now be found
