14" Lenovo T430 + HD6850@4Gbps-EC2 (EXP GDC V8) + Win7 [andrei.tuduran]

Recommended Posts

Hi all,

 

First of all I would like to take a moment and write my history with this experience. Last year I had a Dell Precision M4500 (i7-720QM and nVidia Quadro FX880M) which it had to be my eGPU machine. But using FL Studio alot, the cpu didn't kept the pace so I had to make a change. My research got to my Thinkpad T430 because Ivy Bridge platform can get you up to 90% of peak performance of your eGPU solution. When I had my Dell M4500, I have ordered the EXP GDC V8 Expresscard solution at a pretty fair and decent price (Christmas sales) from Banggood. Shipping to Romania was quite long, almost 2 months. In the meantime bought from a local guy, a Dell DA-2 220W power adapter which I heard it is plug'n'play. After arrival, I found out that I don't have the PCI-E power adapter for the graphic card, in my case a Gigabyte Radeon 6850 OC 1GB. That's the only card I have so, I was aware that I might need a display monitor. After another months of searching, found out on Banggood the holy PCI-E adapter specialy for EXP GDC solution. To be assured , bought 2 cables (just in case :P ) because the shipping was 1 month and 2 weeks (long, I know!). Well, last night I was dying to fire it up, so I put my Panasonic TV ( don't have a display monitor, lame, I know...) and put all cables and adapters together, the expresscard in T430 and fire it.

My specs :

i7-3610QM, 16GB HyperX Impact CL9, 1600x900, Intel HD4000 iGPU, Windows 7 64bit.

After Windows loaded, my Radeon 6850 was found in Device Manager but I got the famous "Code 12" error. The device cannot start because it does not have enough resources.

After 5 minutes of google-ing I found my solution!

Solution : Shutdown your T430, put the expresscard in the laptop and the most important thing, DISCONNECT the display monitor from the graphic card. Start you laptop and let Windows load. The magic will happen, your graphic card starts with no errors. After that, install the drivers from AMD website. I have installed the Crimson drivers.

Connect the monitor to the graphic card and voila! , you have a fully working eGPU solution on your Thinkpad T430.

Still didn't found a solution for the following issue.

In device manager, I had the Radeon 6850 and Intel HD 4000. When I started my Steam or Origin games, the main GPU was Intel HD 4000. My quick solution was to disable from device manager, the Intel HD 4000 iGPU. Maybe someone found a solution to install AMD Enduro (Switchable graphics) like Nvidia Optimus?

I will post later this day, some pics with my tests.

So far I have tested Furmark and i got 35 FPS. Battlefield 3 on ultra setting at 1280x720 (the maximum resolution of my TV) runs flawess. GTA V needs more tweaking. My i7-3610QM cpu got maximum temp of 80 degrees C in games.

 

Edit1 :

Here are some pictures of my setup including the docking station (is the 170W version with USB 3.)

So, this is all about till now.

Thanks for reading!

Looks pretty cool to me. Very clean. Much cleaner than my setup, but I have a much smaller desk space than that.

      Hi,
       
      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!

      Hello, A couple of days ago I got a new GPU but when I installed it into my computer I was unable to use it but now I know why. When checking the device manger I went into the events tab of my GPU when I went to view all events, I noticed an error it said " event 411 kernel PnP " and It also said Problem Status: 0xC01E0438. I believe this is why my GPU hasn't been working on my PC. If you know how to fix this problem or have info on how to fix this problem that would be greatly appreciated. I'm also using a EVGA NVIDIA GeForce GTX 1660.

      I'm having a problem where my PC is saying my eGPU is not usable, its detected in the Device Manager and it doesn't have the yellow triangle next to it. I cant use it games and the Nvidia Control Panel doesn't recognize it either. I'm using a EVGA NVIDIA Geforce GTX 1660. I'm using windows 10 and I tried DDU and reinstalling them and now I cant access the nvidia control panel. The GPU is not recognize on any other apps and I went on *********** and was unable to find my answer, Any help on how to fix this problem would be greatly appreciated.

      Title sums it up.
       
      TL;DR: we have a Clevo that runs a desktop CPU, one with those huge 82 Wh batteries. We remove the GPU and let it use the CPU's integrated graphics. How much time for the battery to go from 100 to 0? Is it comparable to an ultrabook's?
       
      I'm theorizing a mobile set with a static eGPU and an upgradable CPU. Given a hypothetical user that needs fast processing on the go and long battery life while retaining very high degrees of mobility, but at home wants a powerful machine to run most games, I guess that would be their best bet. It would surely be more convenient to keep everything in the same disk. And even though the thing would be quite heavy to carry around, changing CPU would be more cost-efficient than changing an entire laptop. (Not sure if I'm right here, and also I'm not sure whether the motherboard in a Clevo would be replaceable when the new CPU needs a different socket, which is another reason why I'm asking here.)
       
      If my above guesses aren't correct, then an ultrabook with Thunderbolt and without a dedicated GPU would be a better choice. If they are, then we would be carrying more weight in exchange of a more cost-efficient setup, which I think would be a fair tradeoff.
       
      Also I am aware of the heating problems that these laptops suffer from, at least compared to a desktop setup. Would they be solved by moving the GPU out of the chassis, and instead plugging it with an eGPU dock via Thunderbolt port?
       
      What do you think? Is it doable? If not, why?

      Hello !
      I tried a tutorial on the forum to remove the supervisor password on a X260 thinkpad but the winbond 25Q128FVPQ chip is not recognized with the programmer CH341A and ASprogramer (does not detect automatically and not manually). Plugged into the motherboard with a soic8.

      Can you help me with detection?
      Can I find the password with the software or do I have to write it?
       
      Thank you so much !!!
