I disable the M1000M discrete GPU in device manager (I cant see an option to disable it in bios), and perform the driver install to get around Error 43.

Laptop does not shutdown probably or startup properly with the ExpressCard present. I have to hold the power button down to turn off, and hot plug the Expresscard when Windows 10 has loaded.

Expresscard v2 speeds crash with black screen. I have to force Expresscard to gen1 speed in bios.

Performance is not great - 10500 3dmark06. The 1050ti doesnt break a sweat, I assume because of the Expresscard bandwidth being so low. Also using Internal screen - which will reduce the already poor bandwidth even further.

3dmark06 never goes above 38/39 fps, which seems strange. I will try another test.

@amoeba, your P50 has a 6th gen i-core system with Gen3 PCH PCIe ports. So did you know then that with the right EC eGPU adapter like a BPlus , perhaps a PE4C 3.0 (and likely BIOS settings) your EC slot may be capable of running at 8Gbps (Gen3). We have yet to see an 8Gbps-EC3 implementation.

The only dilemma is BPlus want a small fortune for the PE4C 3.0 for you to test whether can get a reliable link:

Your P50 may have a Thunderbolt3 port which would then be a more sensible eGPU performance option:

I didn't know I had the potential for EC3 (I thought EC3 was never implemented, as the wikipedia page doesn't even seem to mention it: https://en.wikipedia.org/wiki/ExpressCard). I might look into getting a PE4C, but they do seem expensive.

Yes the p50 does have Thunderbolt3 - but in the UK a TB3 enclosure costs £300-£500 and that's just too rich for me (I don't game that often).
