It seems that the eGPU is working fine now. It is funny that the higher the setting I choose for SWTOR, the smoother the card run, i got more fps when playing high setting than medium setting with lower resolution. Now every time I want to use the eGPU, I just connect the eGPU, turn on the laptop boot to windows and the external monitor will turn on without using startup.bat or chainload (I still got 2 boot option for Win and DIY in Boot Manager). I guess the eGPU is not working with it full potential is a normal issues as it is not supposed to be like working on a normal desktop. Since the card is a OC version, using EVGA oc tool helps a bit with the game fps. I try eGPU for the sole purpose of playing SWTOR in max setting, looking through some threats I found out that the game seems to depend more on the CPU and the GTX 550 ti I have is enough to play the game in max setting, the i5 m460 seems to be the problem for the reduction in fps.

I am using the PE4H, the mPCI setup is very similar to your L502x. Yes you are right, I just simply setup the eGPU, plug in and the laptop recognized it without any errors. At first I had problem making the eGPU detect the external monitor so I decided to take a look at Setup 1.x to see if it helps and came across the same problem you had when trying to turn off the dGPU. However when i try to boot to window normal (Im using win 8 pro 64 bit), I saw the eGPU fully function without any errors and tried to update it from the device manager and got the External Monitor to appear (instead of disable the dGPU from setup 1.x I disable it in device manager and uninstall the graphic driver and then reboot to windows). I tested the eGPU in World of Warcraft but it doesn't seems to perform as it should be (very low fps). In the end, I tried everything possible with the setup 1.x but the only thing that get the eGPU to output on the external monitor is plug it in, manually disable the GT 420M and uninstall Nvidia graphic driver.

Ok, so I tried uninstall the GT 420M driver completely from Device Manager, try Setup 1.x again, the problem is not there anymore. But in Device Manager now, there appear to have 3 display adapters, one is Intel HD Graphics and the other two is Standard VGA Graphics Adapter ?! Btw, I tried to set the pci_alloc_valid to yes, but when I chainload it keep appearing that I havent done so.

Hello, I am totally new to this eGPU concept and may be also lack the skills to do all of the work but I still want to have a go with it. Dell XPS L501x i5 M460 2.5GHz 8G RAM GeForce GT 420M My eGPU is a GTX 550 ti 1GB. I didn't follow your exact instruction but use simple procedure without using the Setup 1.x. Everything works fine, i got the Laptop to recognized the eGPU and install driver directly from Device Manager. Now in it shows in Device manager that the GTX 550 ti is working properly without any error. When I connect it to a external monitor and reboot, it didn't show on the external monitor. I tried to change the main display, it shows that there is available display output on the GTX 550 Ti but no display detected. I figured that it could be because i didn't turn off the dGPU as the GT 420M still appear in Device Manager so I installed Setup 1.x and give it a try. I cam across the same issue you had when trying to turn off the dGPU, tried the troublesooting with startup.bat but nothing works. From reading this thread, I edit the startup.bat just like yours fix, reboot then run startup.bat script and it just stuck there. Did I mess up the whole thing when installing the eGPU driver without using Setup 1.x in the first place ? It seems right to me since the eGPU is showing without any errors in Device Manager.
