New Thunderbolt Add-on option for Hp Z820

[Tristan Summers]

As of October 2015 this is still not supported under Windows 10.
I have seen a lot of people updating workstations to W10 but a word of warning, Windows 10 not supporting thunderbolt yet in HP Z machines

Hi Glenn, i’m running in the same problem on a HP Z820 and a HP Z420!
On both machines i see only the thunderbolt device ( in my case a blackmagic Multi Dock) but no drives!
The Display funktionality is there!

Have you found a solution? Was here a Bios Setting/Update neccesary?
Any information about this would be highly appreciated!

Thanks in advance
Harry

you need to update the bios, then update the thunderbolt driver then update the BMD driver. You can use the z840 page for some of the drivers, not the bios though I assume. it still may not work but then after restarting a few times and unplugged things a bit it will work. Mine is happy now, but I often have to reinstall BMD drivers as often I can’t see mu ultrastudio. You have to start the device quite a bit before the machine

I hate to resurrect an old thread, but just thought that for anyone looking for solutions to run Windows 10 on a z620 w/ thunderbolt, I have personally had luck.

First one must install all of the HP required thunderbolt drivers and BIOS updates while running a prior version of Windows (I used Windows 7 Pro). Then, do a non-destructive update to Windows 10 (this gives the ability to roll-back to the prior version of Windows to remedy issues). Thunderbolt will work, but you must attach your thunderbolt devices while the computer is off. Ejecting a thunderbolt device while the computer is on will for some reason crash the driver, necessitating a restart. Also, speeds seem limited. For the first few seconds on transfers I get a solid 500MB/s from RAID, which then drops to 30-60MB/s.

All in all unless you already have a z620 that you want to use thunderbolt with I’d say you’re better off purchasing a rig that correctly supports thunderbolt. These workstations are getting old in the tooth.
