The Y570 does not have ExpressCard so you would be stuck with having to use an internal mPCIe port. If you do not have one free you will have to pull your Wifi card in order to plug in your adapter (in this case a PE4L-PMxxxA whereas xxx is cable length, usually 60cm so PE4L-PM060A). A similar implementation of this type of setup would be shown here:

You will need the adapter (PE4L-PM060A in your case since you do not have ExpressCard), GPU of choice (I personally use a GTX 660 Ti), and a desktop PSU to power the card.

I don't see any reports of anyone using that particular system with an eGPU implementation, so you would be the pioneer for that.

You might need to disable your GT 555M in BIOS to give allocation room for the eGPU, but this can be iffy if the vendor disables the iGPU as well.

Since you have no errors, have you tried uninstalling the device through device manager and installing the desktop video driver again? I am currently running driver 327.02. I can confirm this is stable enough. I say it that way since I get driver crashes when I run benchmarks and such. No issues outside of that. Essentially, I can confirm 327.02 is stable for eGPU purposes (unlike some other previous versions....).

I've had pretty much the same error as you with the eGPU error-free in device manager and the nvidia control panel saying there was no nvidia device connected. This occured under two situations:

1. driver crashed

2. dGPU on and only laptop LCD on (no external displays)

Are you using Setup 1.x? Might try enabling Gen2 port through there along with PCI compaction.

Hi angerthosenear , i uninstalled the drivers and installed it again, after that when i configure gen 2 in bios, appears error 43 in the device manager. you told me something about nvidia verde drivers, i used the desktop drivers and tried to install the notebooks ones, but i cant installed it. could you please tell me how to configure these drivers step by step??? there are tutorial in internet, but i cant make it work.

Thanks.

Hi everyone, i have a egpu rig, its working perfect, its likely plug and play, but i have an issue: it was working with expresscard generation 1 in bios settings.

After selecting gen 2, egpu appears in device manager without errors, but is not detected in drivers ( nvidia control panel says not nvidia device conected).

So, my egpu works great in gen 1 but is not working in gen 2.

What can i do to solve this???????

Thanks.
