Hi all,


I'm looking to sell a PE4L V2.1b (Expresscard Version) and GTX750. I have used them both reliably on my Thinkpad X230t, achieving x1.2Opt and able to run pretty much any game decently well, for the past year without any issues. This setup works great as a portable setup since the GTX750 doesn't require external power. I recently bought a desktop so I have no further need for them. Here is a link to the graphics card. I'm looking to sell the PE4L for $60 (got it for $70) and the GTX750 for $70 (got it for $90) or $120 for both, with a flat rate of $5 for shipping. Here's a picture of my previous setup that I was running off the eGPU. If you have any questions or want more pictures of the parts, please PM me!

Nice to meet you. I bought a lenovo thinkpad t420 yesterday on ebay and I want to install an egpu on it. So maybe you can help me with some advice because you have a very similar PC. :sorcerer: It is worth it or not, based on your experience?

The experience was worth it for me. I was able to have an almost plug and play experience with the setup and had a portable setup (the laptop itself) and was able to use more gpu intensive programs such as CAD when plugged into the eGPU. This allowed me to have a great combination of portability and power when I needed either. Thinkpads typically are very easy to setup with the exception of the 8GB memory limit due to memory configurations on some BIOS's. I'm not quite sure if that's still an issue with that memory configuration.


I would like to bring this discussion about price into PMs, but you don't have enough posts to PM yet...

Yes I cant PM because im new in the forum. I started my research on egpu's a couple of weeks ago but after thinking about it I was like :hyper:whatever lets do it. So I bought the lenovo and now im searching for the rest. So your setup doesnt needs additional power supply? Just plug the expresscard to the laptop and the gpu to the adapter and thats it? You can use laptop display for gaming or only external display?

It only requires a power supply for the PE4L board since the GTX750 is powered through the PCIe slot. It can be powered by either an ATX power supply or laptop power supply (12v barrel connector I think), the second also requires a USB to USB cable in order to power the board. The whole system will run at x1.2Opt, but slightly worse performance on the internal display since nVidia will be using Optimus to run that display. On the external display, I was able to run Battlefield 4 at medium settings with consistent 60 fps. Just one thing to watch out for is the USB bus usage -- I had some issues when I had too many USB devices plugged in and would get BSODs occasionally.

I'm not sure what the post count is for PMs, but I would prefer to do that. Or we can communicate over email if you have one I can contact you at.

      I have spent a little time in the past few days looking around this site. I would love for someone to point me in the right direction to a forum that has information that could help me out with my problem.
      I have a:
      Alienware M17XR3 
      Windows 7 Home Premium 64-bit
      Intel I7-2820QM 2.3
      Bios InsydeH20 Version 1.0 A12
      NVIDIA GeForce GTX 460M
      (4x) 4 GB Ram
      samsung 2.5" 256 SSD (SATA3.0Gbps)
      It has been an amazing machine for the last 10+ years. Minor issues, nothing that an Alien Respawn could not fix, till now! On battery power it works just perfect.  Then I plug it in and it's all OK until I try to do anything, and then the screen goes white. The screen sometimes goes yellow, sometimes blue, but mostly white screen. It will do nothing until I do a hard reset (holding the power button till it turns off and turn it back on) with the power unplugged.  If the power is not unplugged then it will go through boot up to windows swirling dots then go white again. If I plug it in and do nothing I can charge it, unplug and continue what i was doing. I have tried a lot of solutions bouncing around the internet, and thought I was having a DC Jack connection issue (replaced the ac/dc power adapter, then the motherboard). I get a better connection now but with the same white screen result. I stumbled into this forum and I'm hoping to find solutions to my issues.  Then upgrade like so many others have.
      Any ideas, comments or suggestions welcome.
      Thank you in advance!

      I need help in fixing my Thinkpad.

      I just got a T440p yesterday. It was working perfectly until the following:

      I reinstalled Windows and then I installed Vantage.

      I installed all the latest drivers.
      I also choose to install the bios update. The bios update ran in Windows and it asked me to restart. After restarting, the screen was blank. I tried powering it off and on and I saw the Thinkpad logo but after that the screen was blank.

      I tried powering on and off again and there's no Thinkpad logo now and the screen is just blank with the green power on. No sound, no nothing.

      Here's what I tried:
      Pressing the power button 10 times and then holding it for 30 seconds. Unplugged and battery is detachted Detached the CMOS battery and the reattached it Removed the ram, harddisk and optical disk drive. Attached the battery and inserted the charger. I turned it on and there was a couple of beeps Tried pressing FN+R and created a bootable USB I'd like to ask: How do I fix this? What do I need to do?
      Can I reflash the bios in some other way? Do I need to buy a new motherboard? Will this solve the issue? It's my first thinkpad and I'm really excited but I was bummed out that this happened. Can you please help me?

      Thanks in advance!

      So AMD is back and in a big way, let us know which products you're most excited about and plan to build. Personally I have a 5950X, ASUS Dark Hero X570 motherboard, and soon an AMD 6900 XT GPU. First time in a very long time for an all AMD build!
