Link is a gen 2 x1 link, and provides a proper playing experience

up until 2048x1536 on VGA and HDMI.

DSDT Override isn't necessary unless you want to use both monitors

at once, although Optimus x1.2 doesn't work. If anyone knows how, please

notify! :joyous:

Only completed Unigine Heaven Benchmark 4.0 so far, result below:


If you have any questions, please ask!

Thanks for reading!

@AeroStar , thank you for your guide.

It's a little unclear on how "although Optimus x1.2 doesn't work", yet the "Link is a gen 2 x1 link". Have you confirmed that GPU-Z reports a x1 2.0 link when the eGPU is under load?

Then to get Optimus' features working (accelerated internal LCD mode working, x1 pci-e compression) you must have the HD4000 iGPU detected and active.

A quick test to see if Optimus is activating is to do 3dmark06 benchmark runs. Results > 10k would show Optimus is engaged.

Speaking of which, would you mind doing 3dmark13, 3dmark11 and 3dmark06 runs and linking their results? That will allow me to add your system in the correct place on the leaderboard at http://forum.techinferno.com/diy-e-gpu-projects/6578-implementations-hub-tb-ec-mpcie.html#post89707 .

Would you mind taking some photos of your eGPU hardware as well? That brings it all to life.

Thank you for the reply!

I will release the benchmark results as soon as they finish downloading (My Wifi isn't too fast!).

Also, normal GPU-Z and the Asus GPU Tweak GPU-Z say the link is x1 2.0, and doesn't mention anything about optimus, which I am pretty sure is faster, right?

Additionally, I did the DSDT Override and because of that I am able to use my internal monitor with my iGPU, and my external monitor with my eGPU, and they both work at the same time. Both GPU's are detected and are working perfectly fine, and my external monitor is selected as the main, and I choose to have both displays extended.

Will post results soon!

Edit: Also will add pictures!

@Tech Inferno Fan Benchmark Results

Ok here are the results from the 3DMark06 Benchmark:


If you need the full Excel file I can send it too. Also, I will

test 3dmark 11 and 13 and add those too.

Additionally, here are pictures of the eGPU rig:



Hope it looks good! Power supply brick is hidden, will post

more pictures of it later!

      We've had a stack of recurring questions from with problems getting a mPCIe eGPU working. This includes GPU-Z not reporting no clock details, error 10/43 or even not being detected at all. Overall it's more troublesome getting mPCIe working than say expresscard or Thunderbolt.
      Here's some common problems and some troubleshooting steps to correct them.
      Getting a black bootup screen, resolving error 10/43 or ACPI_BIOS_ERROR win bootup messages
      Here the BIOS doesn't know what to do when it sees an eGPU. So the solution is to not let the BIOS see it. Do that by setting the delays on the eGPU adapter (CTD/PTD - EXP GDC or CLKRUN/PERST# on PE4L/PE4C). Boot with eGPU adapter in the wifi slot into Setup 1.30 or Windows. Is the eGPU detected?
      I'll add that should error 43 continue AND you have a NVidia dGPU as well as NVidia eGPU then it's likely because of having the mobile NVidia and desktop NVidia drivers loaded simultaneously. Proceed to uninstall ALL your NVidia drivers, use "DDU" to clean NVidia registry entries and do a 'clean' install of the latest NVidia desktop driver.
      mPCIe port that hosted the wifi card disappears when connecting an eGPU in it's place
      Use the Setup1.30 PCIe Ports->enable to enable the missing port.
      eGPU does not get detected
      Overcome mPCIe whitelisting by booting with the wifi card and then hotswapping in the eGPU. That way the BIOS will enable the mPCIe port to work.
      1. Boot with wifi card into Windows, sleep system, swap wifi card for mPCIe eGPU adapter and ensure eGPU is powered on, resume system. Do a device manager scan in Windows. Is the eGPU detected?
      2. Boot with wifi card into Setup 1.30 *carefully* hotplug the eGPU adapter in place of wifi card. Hit F5 to rescan the PCIe bus. Is the eGPU detected?
      If this enables detection then avoid this tedious hotswapping by seeking a unwhitelisted modified BIOS for your system OR test the Setup 1.30's PCI ports->undo_whitesting feature.
      eGPU still not detected - set the PSU to be permanently on
      The latest EXP GDC and BPlus eGPU adapters try to manage the PSU to only power on after they detect a signal. This can cause a race condition where the eGPU isn't ready to go when the CLKRUN signal is asserted.
      Avoid this by jumpering the PSU so it's permanently on rather than being managed. Depending on the PSU you are using refer to the following doco on how to do that:
      eGPU still not detected - a non-standard mPCIe implementation by your vendor?
      PERST# mPCIe pin 22 may need to be isolated due to a non-standard implementation by your notebook vendor: http://forum.techinferno.com/enclosures-adapters/10812-pe4x-series-understanding-clkreq-perst-delay.html#post142689
      eGPU still not detected - faulty hardware?
      If you still don't get detection then test the video card and eGPU adapter in another machine to confirm neither is faulty.
      NVidia driver stops responding
      EXP GDC, PE4H 2.4 and PE4L 1.5 all use a socketted cable and therefore are not true Gen2 compatible device. This error indicates there was transmissions errors.
      The solution is either to get a better Gen2-compliant eGPU adapter such as PE4C V3.0 or PE4L 2.1b (both with soldered cable), or downgrade your link from Gen2 to Gen1 using BIOS options or Setup 1.30

      Required items:
      1.) Lenovo u310 (I have a Core i3 - Ivy Bridge, 8GB RAM)
      2.) 65CN99WW unwhitelisted.
      3.) eGPU (I used a EVGA GTX 750 Ti from another computer I had).
      4.) EXP GDC mPCIe Edition adapter (got from eBay - banggood seller).
      5.) ATX power supply (I used a 600W PSU from another computer I had).
      6.) USB wireless.
      7.) External monitor, keyboard, and mouse.
      1.) Obtain and install a unwhitelisted BIOS. If you are unable to obtain a unwhitelist BIOS, I think it might be possible to bypass it with Tech Inferno Fan's Setup 1.x (may need confirmation as I haven't used it myself yet.)
      2.) Shutdown computer and remove all USB devices, ethernet cables, power cables, card reader cards.
      3.) Remove mPCIe wireless card and detach antennas.
      4.) Attach EXP GDC external mPCIe cable to the former wireless slot and screw down.
      5.) Attach HDMI end of the mPCIe cable adapter to the EXP GDC device.
      6.) Attach graphics card to the EXP GDC device (I moved my laptop off the desk and onto the side shelf to make room on the desk for the monitor/keyboard/mouse).
      7.) Using the power cable adapters that came with the EXP GDC device, I hooked in my ATX power supply's 20 pin and CPU 4 pin cables. Then hooked the other end (8 pin) into the EXP GDC device. My EVGA 750 Ti also required that I use an additional PCIe power cable (6 pin) in the top of the card.
      8.) Then I attached my misc devices (HDMI monitor, USB keyboard/mouse/wireless adapter), and hooked in my PSU and powered it on (below is image of final product, also moved HDMI cable out of the way).

      9.) Power on your computer and let it install the standard VGA drivers and then install your drivers (I didn't have to go in the BIOS for any graphics settings, which it doesn't have anyways, nor did I have to disable iGPU in Device Manager before the card was added).
      Extra Info:
      I found that most games will play on med settings with about 45 FPS with this particular card.
      BDO: Upscale on - Anti Aliasing on - SSAO off - med settings.
      Skyrim: Med-High settings.
      Fallout 4: Med settings.

      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?
