Z 230 Workstation
Microsoft Windows 10 (64-bit)

I hope everyone is well.
I am looking for a HP THUNDERBOLT-2  F3F43AT / 753732-001 card with the HP 751364-001 Internal header cable.

The header cable is specific to the Z230 Workstation..

Here's an example of the card with a header cable for the Zx40 models from ebay.



Can anyone help me?

Ive read the following;










I'm wanting to add Thunderbolt to connect to an Audio Interface due to it's better round trip latency than USB.

I don't care about daisy chaining to a monitor.

Any help would be greatly appreciated.

Many Thanks,

Here's another link that references the card.




Many thanks (hopefully) in advance.

FYI,.......both HP and Dell use the same Intel Reference TBolt 2 card, however i suspect each company may use a different pinout on the motherboard dell may have published the motherboard TBolt 2 pinout so check them for a cable and board pinout


the pin connections on the TBolt 2 card remains the same between Dell/HP, only the motherboard pinout may be different


as long as you get the power and ground lines correct, using a multimeter, you can then by trial and error determine the other 3 lines



dell# GGTXK  is the Display port wrap thru cable


NK4P3 is the GPIO cable to the motherboard.


07HMHP is the Dell TBolt 2 card  part number

Thanks DGroves.


The Z230 has only 2 header pins on the motherboard. The other models have more and seem, by the look of the cables to have some jumping going on.


I'm an electronics novice at best.


I wonder does anyone knows if the 2 header pins on the Z230 motherboard are power & ground?


I really appreciate you taking the time to reply DGroves.

not having this system i obviously will be making a educated guess,


looking at this document


  1. small form factor models – the port is near the edge of the board
  2. Tower models – the port is between slots 3 and 4




note the z230 illustration, it shows the 2 wires from the motherboard board connector labeled E102 go to the pins on the edge of the card this narrows down the possible connections as it will be only 2 pins so the question is which pin on the board to which pin on the card (only 2 ways to connect so you have a 50/50 chance to get it right the first time)  also does the header short any pins? i would guess it does not 


i suspect the 2 wires are sync signals or sync/ground if one is a ground, this can be confirmed using a multimeter simply touch one pin on the e102  to a known system ground and if it has continuity it;s a ground connection
