HP z840 Thunderbolt card connection cable

[A4M]

Hi

I have Z840 workstation.

I have bought GIGABYTE GC-TITAN RIDGE 2.0 Thunderbolt3 Certified PCI-E Expansion card. This card comes with Thunderbolt™ Header Cable (5-pin) And Thunderbolt™ Header Cable (3-pin). 

these two cables fits the card side perfectly but it cannot be connected to motherboard tbt1 connector GPIO (General-Purpose Input/Output). The motherboard connector has 7 pins. Three in one line and four in another line.

How can i solve this issue?

I have found this  HP Z440 Thunderbolt Card GPIO Cable for sale. Can this cable solve this problem?

@A4M -- is this the card that you purchased: GC-TITAN RIDGE (rev. 2.0) Key Features | Motherboard - GIGABYTE Global

It interfaces to the motherboard via the PCI-e interface.

That web-page shows several cables that connect from the adapter-card to external devices -- not to the motherboard.

So, what is your reason for trying to connect the cable(s) to the motherboard?

@A4M -- The card didn’t work with the pice 

Please elaborate. Did the motherboard detect the add-in card?

Within the Windows "Device Manager", is it shown as a deivce.

Are there any "yellow-triangles" within Device Manager, to indicate that you need to install device-driver software?
