Hi, can someone please help me out with my eGPU setup??
I have a T420, Intel 3000HD + Nvidia NVS 4200m setup. I'm running Windows 8, i7, and 8gb ram. I have the PE4L 2.1 and a GTX 560Ti, Corsair CX430 power supply. For some reason my PE4L didn't come shipped with an ATX power supply so I'm using the paper clip trick to turn on the PSU. I have my SW1 set at 2-3 and SW2 set at 2-3 (although I've read that SW1 should be set to 1, my computer can't detect the eGPU when it's set at 1; I do get both LED's on the PE4L though in either case). I've been desperately trying to setup a x1.2Opt setup, but I've been getting blue screens all over the place...
The most common error I've been getting is that when I plug in my eGPU, my USB ports and Wi-Fi card become disabled. These issues become fixed when I hard reboot the computer, so afterward I tried installing the latest Nvidia driver (the Verde version with nvram file modified), yet when I try to open the Nvidia Control Panel, I get an error message saying "Nvidia Display Settings Not Available: you are not currently using a display attached to an Nvidia GPU." Also on my Device Manager, my NVS 4200m is still listed, although it shouldn't be...What is the easiest way to setup the eGPU on a T420? Do you think I need to purchase the Setup 1.1x in order to correctly set the computer up, or do a DSDT override (how do you do this for windows 8??) Thank you so much!
