Driver Install on Akitio and HP Z Book G2
Firstly thanks to everyone who unknowingly contributed to me deciding to go down the eGPU route, I've been lurking for some time.
OK, so I bought the Akitio Node Duo and have hacked it about a bit so that I can fit two GTX980TI in there, once working I'll make a spacer for the case out of billet alloy. In addition there's a Seasonic X Series 1250w PSU powering the two cards. I have the PSU Power-On pin shorted in order to power up the PSU, works fine.
The Akitio is connected through an Apple Thunderbolt 3 to Thunderbolt 2 adapter. It evidently makes a connection as the indicator light turns blue and more importantly the two cards can be seen in Device Manager (Win 7 Pro) and will hotswap.
The issue I have is trying to install the drivers. The Z Book comes with an on-board graphics chip and a K3100M. The on-board is easy to disable but not so the K3100M as there is no BIOS setting to disable it. Short of removing the K3100M does anyone have any suggestions?
I've tried using the latest nVidia drivers but get the error message that no compatible hardware can be found, I've also tried disabling/uninstalling the K3100M but it sneaks back in again. I set it so that the system doesnt update drivers from Windows Update but still no luck
Disable your K3100M by disabling it's hosting PCIe port.
Do that by highlighting the K3100M in Device Manager->Display adapters. Then select View->Devices by connection. Directly above the K3100M will be a PCIe port. Right click disable it after which the K3100 will also disappear.
Proceed to uninstall any Quadro drivers, then install the Geforce eGPU drivers. There should no longer be any incompatibility issues for your GTX980Ti cards.
OK, so I managed to get drivers installed by unpacking them and doing it the old way.
Both cards are now showing correctly in the Device Manager but the K3100 is still installing before them so i cant use them.
What I may do is remove the K3100M which means when I'm not able to connect to the eGPU I'll have to turn on the on-board graphics in the BIOS. Shouldn't be a problem.
