    eGPU experiences [version 2.0]

    An update to my situation: I have not had a chance to test some other graphic card, but I tried a PSU just in case. Everything exactly the same.

    I do not have a power strip with on/off switch right now, but I tried the 5V charger from wall and also straight from the computer, both got same results as before. If I have the power connected (both AC and USB), D1 (green) and D3 (yellow) are lighted up. And now, if I plug in ExpressCard (computer is turned on), D4 flickers red and turns off, D2 turns red.

    I tried my setup again. Tried different SW settings. When I plug in the DC adapter to PE4L, gpu fan starts to spin really slow and none of the LEDs lighten up. When I now connect the USB to PE4L, D1 (power) lights up green, D3 (detect) yellow. If I now plug the PE4L ExpressCard to my laptop, D2 (flag) lights up red.

    Thank you for that. Is there any way that I could check the cable before getting a new one? Also, if I understand correctly, the new PE4L-EC cable should be soldered in?

    I tried different SW1 settings, but it did not change anything.

    My setup is Lenovo x220 + Nvidia GTX650: [GUIDE] Low profile 12" Lenovo X220 + GTX650@x1.2Opt (PE4L 2.1b) - Page 2 E4L 2.1b + EC2C with EC-060A ASUS GTX650-E-1GD5 GeForce GTX 650 PCI-E 3.0 GDDR5 1GB 128-bit Memo 5000 MHz EZCool AD-970-90W universal laptop adapter (with different connectors) Lenovo X220, 1.38 BIOS USB to USB cable Settings used: BIOS: PCI Express Speed: Automatic, PCI Express Power Management: Off PE4L: SW1: 1, SW2: 2-3 After using it for almost two months, it stopped working. I hadn't used it for almost a week. My standard power-up process 1. DC adapter to PE4L 2.1b 2. USB 5V (connected to DC adapter) to PE4L 2.1b 3. PE4L to my laptop via ExpressCard Adapter. 4. Power up laptop and everything works. However, at the moment, when I plug the 5V to PE4L, GPU fans goes really loud and fast, also nothing comes up to the laptop. Also nothing comes to Device Manager. I also tried to take the 5V from laptop, but did not work.
  7. I searched for the drivers: Did not look for specially "internal LCD", as there are no such drivers, I guess. However, after not using the eGPU for a week, I plugged it in yesterday and it did not work anymore. eGPU is not detected by my laptop and the GPU fan is spinning real fast. Any ideas? I have read something about JP4 or similar jumpers, but not sure what they are.
  8. Thank you very much Remko78! As I also happen to have Lenovo X220 with 4GB RAM, I followed your setup and ordered the same things E4L 2.1b + EC2C with EC-060A ASUS GTX650-E-1GD5 GeForce GTX 650 PCI-E 3.0 GDDR5 1GB 128-bit Memo 5000 MHz EZCool AD-970-90W universal laptop adapter (with different connectors) Lenovo X220, 1.38 BIOS USB to USB cable Settings used: BIOS: PCI Express Speed: Automatic, PCI Express Power Management: Off PE4L: SW1: 1, SW2: 2-3 Everything went smoothly aswell. 1. Download GTX650 drivers and install them 2. Connect power supplies for the PE4L 3. Connect Expresscard adapter to your computer (windows will probably install some things for you) 4. Enjoy (maybe a restart is required) Cool thing is that the laptop adapter had also a USB 5V coming out and I did not take the portability hit there. Although, the adapter is 16V with this connector, but everything is working properly... for now. Couldn't find any information on PE4L on how much voltage can it take. I have not made a case for it yet, but I am looking for one. I tested it out with Counter-Strike: Global Offensive. Without the PE4L, my FPS rate was from 10-35 with all video settings low. With PE4L, all video settings are on high and my FPS rate is 80-110.
