@bryanangg In my experience it's not very necessary to reverse the DSDT (unless you're sure it's the issue.) I recommend getting everything working with OSX if for no other reason than to avoid startup kinks. Since you have a Node, whereas I have a Thunder2, it might not be exactly the same but try the OSX config before stepping back.

Ok worked now, eGPU is running. Driver 375.63 was the only driver to work with my Palit 1050ti, else I got Error 43. 

 

But the performance is a little bit shit imo xD. I get about 100% performance increase with the eGPU in comparison to my Intel HD 4000 (running on internal Display). Is there a option to see if I'am running x1.1 or x1.2 link speed?

You can check your PCIe link speed in GPU-Z. I did not read your previous posts, so I do not know if you stated this or not, but are you running an external display? eGPU setups with just one PCIe lane suffer quite a bit if you run on the internal display.

EDIT: Oops. It was right in the post. Internal display. Sorry...

Want to output 4K@60Hz out of an old system on the cheap? Read here.
Give your Node Pro a second Thunderbolt3 controller for reliable peripherals by re-using a TB3 dock (~50$).

Ok, it says x1.1 when its not used, while in game it said until now always x1.2. 

But I have to correct myself, its actually 3x to 4x times faster than my intel hd 4000.

Yeah, the PCIe link speed drops to Gen1 when the card is not utilized, so the fact that you're seeing x1.2 when in game means everything is working as it should.

WARNING: A Clover DSDT override can brick your Macbook

Guys, a warning has been placed against Mikeal's Clover Macbook DSDT override method here at here  as shown below. This is because it's not an in-memory method but rather an firmware volume write method which is far more dangerous. Thank you to goalque for identifying the source code doing this.

 

 BIG WARNING by nando4 >> @Goalque has correctly identified that Clover loads a DSDT table in firmware volume and as such can brick a Macbook as this user  found. If you proceed with using Clover to do a DSDT override the  you do so at your own risk!! For risk-adverse users it is suggested to simply do a DSDT registry override and persevere with Windows' test signing mode until other solutions are found and presented.

At this moment, the pre-boot mechanisms to load a DSDT table is via Clover (UEFi) or Setup 1.35 (MBR).   If you manage to get a MBR Win10 installed on your 2016 Macbook then I can help you. I have yet to see anybody do that.

An alternative to Clover is being investigated.

Hello, My setup is an HP Elitebook 8460p with 16GB of RAM, and Windows 7 Professional, trying to run a GTX 970 with a 600W power supply (With the EXP GDC for Expresscard).

A few months ago I started to try and make my setup work, then I was having too much trouble, and I am trying again, and with the new website and instructions I got up to the point where I got the Large Memory (I was having Error 12), but when I boot with the graphics card, my system just stops at the Windows Logo after going smoothly for like half a second, and goes frame by frame every minute or so. I was wondering if anyone had the same problem and could help me. (Attached is a picture of the Large Memory)

Also, were you suppose to make the large memory thing with the graphics card in your computer already, or does it not matter? (It didn't say anywhere on the instructions and I didn't)
