(EXP GDC Beast v8.4d mPCI-E + GTX970 + ATX PSU) eGPU project for Lenovo IdeaPad Z710, i7-4700MQ, 16GB RAM, SSD, GeForce GT745MBy damianalex
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.
Nvidia GeForce GT745M
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.
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.
I will describe next step when I get all stuff I need!
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.

all made by hand with the tools I had.
Hi, I'm having problems trying to connect a GTX 750 Ti to my Lenovo T420 using the dock EXP GDC Beast (express card version).
My laptop: Lenovo T420
RAM: 8GB DDR3
CPU: Intel Core i5 2520M
GPU: Intel HD Graphics 3000
My problem is: if I plug the express card and I turn on the laptop it doesn't boot up and the screen becomes horrible, with coloured pixels and a sound like "bip-bip".
If I try plugging the express card when the laptop is already turned on it sees the gpu, but if try installing the drivers I have to apply the modifies restarting the computer.
I hope you understood my problem (I don't speak English very well).
Please help me, It's making me crazy!
EDIT: I didn't say that if I plug the express card when the pc is already turned on, in the device menager there is "Error 12" on the gtx 750 ti
I have a lenovo y480 trying to set up exp gdc with mini pci-e. I followed the instructions to the letter and still my system does not detect it. graphic card i am using is a evga 1060 and windows 8.1 I am willing to upgrade to win 10 if that would make it easier, just looking for some guidance since i am a beginner at this.
