2018 15" HP ZBook 15 G5 (Q P1000) [8th,6C,H] + GTX 1070 @ 32Gbps-TB3 (AORUS Gaming Box) + Win10 [switch]
So after running for 3 years with a 3rd gen Zbook, I upgraded the laptop to a 5th gen ZBook with Quadro P1000. It was a one-shot offer and the dGPU was literally free.
The 5th gen Zbook is pretty similar to my previous 3rd gen. It now has a 6core/12thread H-rated i7-8850 CPU. There are three major differences for eGPU enthusiats: it has a Titan Ridge TB3 controller, it (shouldat least partially) be chargeable via USB-C and it supports DP 1.4 (as opposed to 1.3 on previous gen). The tb3 controller with two external ports still has a PCIe x4 to the PCH and by default supports the full 40gbps communication speeds (unlike other laptops).
The setup is pretty straightforward:
- make sure you have the proper drivers (from HP) for both TB3 controller and video (intel+nvidia); the info below assumes you don't have any external display available;
- connect the eGPU to a power socket then to the ZBook via USB-C;
- authorize the TB3 connection in TB3 software (assumin default BIOS settings)
- your eGPU will likely NOT work at this point (you'll get Error -43)
- reboot the laptop while keeping the Aorus attached
- still won't work at this point; install latest drivers from nvidia without any cleanup in advance (this LACK of cleanup is important);
- reboot once again and enjoy a fully functional eGPU setup; the laptop WILL revert to using the dGPU if and only if the eGPU is not attached; it may also be assigned manually to PhysiX processing during games;
The only issue is that the laptop will NOT charge from the Aorus. I don't know why nor can I troubleshoot. It's extremely difficult to figure out what's wrong when all you can do is connect or disconenct a cable and look at a LED.
