Hey Guys!

I bought the EXP GDC v8.0 to use with my laptops:

Alienware M17x R2 (no iGPU)

 

Alienware M14x R2 (iGPU)

  • i7 3840qm
  • GT 650M
  • 16GB DDR3 RAM
  • mPCIe x2(?)
  • Windows 7 x64 Ultimate

 

I am using:

 

My problem is that Windows does not detect anything on either setup. No drivers are ever installed for a "Standard VGA Adapter", and I always check Device Manager. I have tried everything on the TechInferno webpage here, but nothing happens once in Windows. I have entered into the DIY eGPU Setup (menu option) several times trying what it recommends to get the graphics card to be seen, and messed around a bit with the settings, but none of that works either. Sometimes certain options will cause the laptop to hang and force me to reboot.

The ExpressCard slot and mPCIe slots of my laptops do work, I regularly use the ExpressCard with a USB 3.0 card, and I normally have a WLAN and a M.SATA SSD drive in the mCPIe slots (both I have extensively tried with the EXP GDC adapter). The graphics card only boots up (with fans on full blast) once the PSU is plugged in after the BIOS has loaded. If I have it connected from a cold boot, the card will attempt to turn on with slow fans and then turn off on either laptop. The graphics card is lightweight and fully inserted into the EXP GDC adapter. There is no switch on the PSU, so once everything is plugged in (and the laptop is on), it just goes.

I thought it would at least work on the M17x R2 since there is an Amazon review comment stating that it does. The only other thing I can mention is that the GTX 680M was never officially meant for the M17x R2, so I have to hack the NVIDIA display drivers to get NVIDIA driver support. I don't think this has anything to do with the eGPU detection though (especially since the DIY eGPU Setup dose see the GTX 680M)... And, if it helps, I do have a Dell 220w power brick I can use instead.

If anyone has any suggestions I can try, I will, as I really want this old laptop to run at its best before I move on.

Thanks in advance!

For the sake of closure, the PSU did seem to be the problem. Once I had the Dell 220w power brick inserted, and the right cables to go from the female 6 pin on the EXP GDC adapter to the two female 6 pins of the Zotac GTX 970, it was immediately recognized in Windows once the laptop booted up. I then just had to restart, install the drivers, restart once more, and I was then able to use the GTX 970 for gaming and whatnot.
 
I have yet to test this with the mPCIe, only the ExpressCard. I may have to tinker with the mPCIe setup, but I'll find out soon enough...
 
As a side note, I have been able to overclock to 1476Mhz on core without any changes to power or temp thresholds!

Hi, I  have a similar problem, I cant recognize my eGPU on my laptop. I tried everything as you did, but I'm not sure I understand what you did to fix. what cables are you talking about ?

      Hi,
      I want to show you my new project.
      I bought my laptop about 5 years ago.  It was never speed deamon, but for every day use, it was enough to me.
       
      Its specification:
      Intel i7-4700MQ
      Nvidia GeForce GT745M
      16GB RAM
      512 SSD Adata SU800

       
      Yesterday I bought Witcher 3. Of course on 1080p it's impossible to play, because of about 10fps
       
      So I make a decision to buy external grahpic card.
      I choose GTX970 and now I am looking for occasion to buy it.
       
      I've already bought EXP GDC v8.4d mPCI-E. It is used and cost about 30$.

       
      I will use ATX PSU to supply graphic card, because I have old desktop PSU at home.
       
      My plan:
      1) unlock bios
      2) buy GTX 970
      3) enjoy Witcher 3!
       
      BTW I try to cool down my laptop, so I replaced thermal paste to Kryonout Thermal Grizzly and make some tests. Temperatures and fps are on screenshots.
       
      1) laptop on table, playing GTA V 1080p

       
      - first minute (GPU core 1045MHz)

       
      -after some time, because of high temperature and GPU throlttling (GPU core drop down even to 400MHz)

       
      2) with thermalpad Glacier NC400 SilentiumPC

      - 30 minute and longer (GPU core drop to about 900MHz)
       
      3) without down case of laptop (like on picture with thermal paste) on thermalpad.
      Here laptop never drops down MHz and max temp are about 72 Celsius degrees.

       
       
      Bacause of that I bought second down case for my laptop and I will cut there additional holes.
       
      Greetings!
       
      I will describe next step when I get all stuff I need!

      Hello everyone
      I created a case for egpu using 2.5mm acrylic sheets. The first time I created a case to support a GPU + ATX psu
      Now I created another one for the GPU with an external Xbox 360 203w psu.
      the finish was not good but for my use it is already good.
       
      *both cases album
      *Construction of the second case 
      *adapting xbox psu to 8pin power (taken from 24pin)
       
      all made by hand with the tools I had.

      from Brazil.

      Hello!
       
      I have recently acquired my Dell Inspiron 15 7000, and I am interested in building an egpu setup for it. It has a USB-C port. Any recommendations/guides out there?
       
      thanks.
