Hi,Matthew!good to hear that! i suggest to use gpu- z and look if your card runs in x1 2.0 mode under load.regarding the benchmark,i also have that C0 score,but only with internal screen.it would be nice to post the result for your benchmarkings using external screen if gives you a legible score.Thanks!

Hi again, Dan!

As you said, when I run 3DMark06 on external monitor the score works! I got 22500 points!!

GPU-Z shows that my GTX750Ti runs at PCI-Express x1 2.0

Thanks again for your help

Hi! Guessing that you don"t have in the bios option to disable the dgpu [check that] you have to disable the dgpu within o.s.To do that,yo have to go to device manager then System device and find the pci/express that host the dgpu.Be sure that you have install the setup chipset from intel site,otherway that pcie won"t show up.As you can see in my case ,i disable the pcie controller that host the dgpu ,and it disappeared from the dysplay adapter list.From here install the egpu driver and you have to see this option of choosing betwen igpu and egpu as a grafics processor the trick is to wipe out the dgpu from the display adapter list..[ATTACH=CONFIG]14298[/ATTACH]. [ATTACH=CONFIG]14297[/ATTACH]So,is not enough to disable it from display adaper list since the o.s still see it as a basic vga adapter,you have to search for that pcie controller that host the dgpu and disable it[not unninstal] in system devices. It works for me in W7,W8.1 and W10. I am sure that it will work for you also.

Just tried it and it WORKS!!! You're the best, thank you so much! I was disabling/uninstalling the PCI root, not the PCI-e

I've done benchmark in 3DMark06, but when I was redirected to browser to see my score, it showed C0...Anyways, I was getting roughly 2times more FPS then before and for example War Thunder maxed out runs 25 - 40 FPS!!

If you want, I can try to run the benchmark again...

Hi maty_CZ! you have a nice setup!and it is optimus compatible.in order to actívate, you have to disable the dgpu from your system. This can be done by disable the pci-express that host the dgpu in the device manager or using x1 setup provide by Tech Inferno Fan.you will see a big boost mostly in dx9 aplications.the score in 3dmark2006 will go up to >20.000 points. and also you can use the internal screen with the egpu .

Hi dan! Thank you very much for clearing that up!

I have UEFI bios, that means that x1 setup wouldn't be the best solution, so I tried disabling PCI drivers.

dGPU is connected to PCI port no.1, so I uninstalled dGPU driver (I had it only disabled, not uninstalled) and I also uninstalled PCI driver no.1, but when I restart my laptop, PCI driver is reinstalled and dGPU is recognized as a Video controller (compatible with VGA)...Could you please tell me what is the best solution for this problem?

Hi guys!

In this post, I would like to briefly describe my specs and how I've attached eGPU to my laptop ASUS K55V.

Specs of my laptop:

• Processor - Intel Core i7 3610QM
  
• dGPU - Nvidia GeForce GT 630M (2GB)
  
• iGPU - Intel HD Graphics 4000
  
• RAM - 8GB
  
• Win 7 Home Premium
  
• PCIe 2.0
  

Adapter that I use is EXP GDC v7.0 mPCIE version

The eGPU I bought is Nvidia GeForce GTX 750Ti Gainward 2GB DDR5

Implementation:

1. Attach eGPU onto EXP GDC (I had to push it relatively strong on the adapter)
   
2. Attach PSU (I used White Energy power supply for LED strips/tapes 60W, pin positive, DC jack 2.1mm x 5.5mm)
   
3. With laptop turned off and with removed battery, remove WiFi card from its slot and then attach the cable from the adapter
   
4. Boot up the laptop and in the device manager disable dGPu -> restart
   
5. eGPU is recognized as standard VGA adapter -> install official driver from nvidia website
   
6. Restart (I had to few times)
   
7. eGPU is recognized as GTX 750 Ti
   

So that's how I've done it, my internal monitor works and my secondary monitor works too.

BUT I can play games only on secondary monitor (external monitor), because it's managed by GTX 750Ti and internal monitor is managed by Intel HD Graphics 4000. When I open up nVidia control panel GTX 750Ti is recognized, but it only manages secondary monitor. I don't really get the Optimus tweak, could someone please tell me if it's possible on my setup and how should I do it?

Also 3D Mark 06 benchmarks my dGPU and GTX 750Ti isn't probably recognized. I think so, because I only get 12.000 points and my dGPU is marked as primary in 3D Mark...

I would like to say thank you very much to everyone who've done this forum, it really helped me.

I didn't have to spend 2500$ on a gaming laptop and for only 300$ I upgraded my laptop and extended my laptops service life for another 2-3 years.
