Theck out mydigitallife or bios-mods forums. They have threads for bios requests.
Good luck with the thing. Don't forge that if you want to cold boot you have to have dGPU enabled in the bios.

Cheers.

I wonder will it work with this version or with just the mini end cable, because there are lots of usb 3.0 male to male sold in my country than the mini end to male usb 3.0 cable.

I think that it doesn't matter as long as it fits port on your laptop. This is regular x1, right? For laptops you need mini-pci to mini usb.
I'm pretty sure it's just an adapter in the end. Unlike thunderbolt docks which are actually separate devices not just a passthrough.
tl;dr get a mini version like the one linked up in the OP.

Still wondering why x1 gen 2/usb 3.0 combo isn't 500MB/s but only peaks at 402MB/s during gpgpu/cuda-z benchmarks. But hwinfo monitoring overlay reports 5.0GT/s during gameplay, so I would assume that it actually does use full potential of bus.

500 MB/s is the theoretical maximum which does not include:

  • Transaction Layer Packet Overhead
  • Traffic Overhead
  • Link Protocol Overhead
  • Flow Control Protocol Overhead

The overhead varies depending on system parameters:

  • Maximum Payload Size
  • Maximum Read Request Size
  • Read Completion Boundary
  • Posted and Non-Posted Transactions

Reference:  https://www.xilinx.com/support/documentation/white_papers/wp350.pdf

There is also the efficiency of the gpgpu/cuda-z benchmarks to consider. How fast does it repeat each read/write? The benchmarks don't show any PCIe errors that might occur which would require a retransmission of a packet. Is the error rate using a USB cable higher than normal?

That was very informative, thanks!
I have no idea about error rate.

I have a late 2014 MBP and I was wondering how I can get around the mPCIe to USB that you have set up in the back of your laptop. I have Thunderbolt 2 ports, is there a way to use this with a workaround? If not what can I do, I purchased the $7 extender and I have a PSU/GTX 1060 but I'm not sure what else to do. Thanks!

is it working on internal screen ? I mean , does it work on laptop LCD ?

You want to use mPCIe with a MBP? Why not use the Thunderbolt 2 ports which can transmit data faster?

This is basically what I want to know. What can make my GPU work via TB2? I purchased this, although I'm not sure what else I need besides this to connect to TB2.

Thank you so much for your consistency.
I wonder which GPU would be wasting if we use with this bandwidth as you said the bandwidth is limited in mPcie.
gtx 1070 will have the same performance with 1060 because of mPcie potential?!

the second question is the internal lcd.
can I use my laptop’s LCD or should I connect my laptop to an external motitor?!( if so, should I connect hdmi cable directly to egpu or my laptop’s output?!)

I will appreciate of you answer me.
