I hope I'm posting this in the right section and yes, I used Google, the search function and the troubleshooting guide.
I'm trying to get an eGPU setup up&running but I encountered some major problems.
First of all, here are the specs for the hardware:
Acer Aspire V3-772G
CPU: Intel Core i7-4702MQ, 2.2GHz - 3.2GHz boost
dGPU: Nvidia Geforce GTX 760m
RAM: 16GB DDR3
PE4C-PM060A V3.0 (via mPIC-E)
PSU: Cooler Master B600 Ver.2 - 600W/+12V/PCI-E
GPU: MSI Geforce GTX 970 4G - 4GB vRAM
I don't really know where to start, so lets begin how everything is connected.
The Acer-Aspirve V3-772G has 2 mPCI-E Slots. Both were previously occupied (SSD MMC, and an Wifi-Bluetooth card in the half/small port). I tried the following steps on both mPCI-E slots without any changes.
For the first try, I just removed my WIFI card and connected the PE4C to my laptop. Next I inserted the new GPU and connected the power from the PSU (1x24p ATX directly from PSU to PE4C, 1x6pin and 1x8pin from the 6/8p output from PE4C to the graphics card).
On the first boot, nothing happened, the screen stayed black but the gpu-fans started spinning and the status-leds switchted to green, so I tried different troubleshooting steps.
Different boot-delay settings for the eGPU - made no difference, the screen stay always black (no signal) but it seemed to result in different fan-speeds on the gpu
My next steps seemed to work at first, because the GPU-fans started spinning really fast, without any crashes or "not working display". But in every case, neither the GPU or the PE4C could be detected by windows.
Turn eGPU ON when windows initializes
Turn eGPU ON after standby (booting with eGPU OFF)
Hot-Swap WIFI and eGPU (from standby - with and without wifi card on boot)
After this, I completly removed the nvidia drivers (for mobile) and deactivated the dGPU via device-manager and repeated the above steps (hot swapping...) but with the same results. Either it halts on boot with "no signal" or it doesnt get detected at all.
After further research, my next guess was that the dGPU messes with the eGPU on startup, so I bought eGPU Setup 1.30
After making a USB-Bootable drive, I booted the setup "with menu"
First, I booted with the Wifi-Card, wich worked fine (detected) and gave me the pcie port, where my eGPU should be setup.
After this I continued with the previous steps (turn egpu on at boot, in menu, hotswapping...)
With each variant, (after disabling the dGPU) I tried to initialize , reset, deactivate/activate the correspondent pcie port - including different gen setups.
The result stayed the same as in Windows, the eGPU won't get detected in eGPU Setup 1.30 (the pciport shows nothing after his id -> pci3 1.2x: )
Now I am out of ideas and wonder if I am just doing something completly wrong or the eGPU Adapter is simply not working with my laptop.
Of course I researched before buying the equipment... which should work fine with my laptop...
I also can refund my GPU (today or monday) but would prefer not to
I appreciate every helping hand, who can give me a clue how to fix this.
