External LCD monitor (HP 2511x)
I've the same build, but when I bootup the laptop, the screen goes black and nothing appear on screen, I'm using an external Monitor. The ATX PW is ON and PTD set to minimum delay on the adapter. When I try to hotswap, booting first the laptop after turning on the EGPU, the device manager of Windows don't recoganize the GPU. As I said, my laptop CPU and the adapter EXP GDC is the same of yours and I'm also using the GTX 1070, I just didn't' try yet to use the DIY, what configurations have u done to get the egpu working? I think the only difference is that I'm using the expresscard slot instead of the mPCI
My best bet is to reach out to Nando for some help with your DSDT file and use the DIY from @ Nando 's DIY eGPU Setup 1.35
I have my monitor connected with a VGA cable on initial boot up, and I have to have the expresscard adapter UNPLUGGED from the laptop.
Then just before loading into Nando's DIY bootloader, I turn on and plug in the expresscard adapter.
You'll need to configure your settings and test the settings in the eGPU Setup.
After everything checks out, you'll save and run the settings.
I wait until I get to the Windows login screen and this is when it usually freezes.
Then I unplug the VGA cable and I have a DVI cable already connected to my eGPU to my monitor.
I think I also removed some drivers for the discrete onboard GPU and updated some of the drivers for my GTX 1070.
Hope this sort of helps. Reply if you need any more help. GOOD LUCK!
No problem. Yeah, I tried messing around with my settings but the DIY was the simplest way to get it up and working.
