15" Acer Aspire 5742G + [email protected]+c-mPCIe1 (PE4C 1.2) + Win8.1 [Niskon]

Recommended Posts

masterblaster 2.0 comment>> This is the first Windows 8.x implementation where a dormant iGPU was activated to enable x1.Opt (x1 pci-e compression) on a 1st gen i-core (dual core) system supplied by the manufacturer with a dGPU only.

First I want to say thank you for Tech Inferno Fan for his huge help the whole project and I want to apologize for my bad english. I'm from Germany and still a student so be surprised :)

A long time ago I saw a video with an graphics card running external connect to an notebook. I always thought about doing this by myself and one day I decided to order an eGPU adapter and the graphics card.

First the specs of my notebook:

Model: Acer Aspire 5742G

CPU: i7-640m (upgraded from an i3-370m) with dormant Intel HD iGPU not connect to LCD

GPU: Nvidia GeForce GT420m dGPU only

RAM: 8GB DDR3

So now we are getting to the things you need:

  • free mPCI slot (unfortunately the Aspire 5742G has only one slot, so you need to remove the Wifi-Card. In my sitution no problem because I'm using lan either way.)
  • PCIe -> mPCIe adapter (PE4L, PE4H or what I used the PE4C)
  • A GPU of your choice (I chose a Nvidia GeForce GTX660Ti)
     
  • A PSU that has enough power (I used an PSU with 550W found in the basement)
     
  • Setup 1.x (buy it from Tech Inferno Fan for 25$) -> it's necessary, without you wouldn't be able to run the eGPU
     
  • A case or something to store you eGPU + GPU (not necessary, but looks tidier)
     
  • Windows 8.x (I wasn't successful with Win 7. If you want to know more about it, you can read more here.)
  • External Display -> internal isn't working because the dGPU is disabled and the iGPU isn't connected to the LCD
     

Some explanations:

The biggest problem about the whole process is that the Aspire 5742G has a iGPU but it's not connect to the LCD and even if you have enabled it via Setup 1.x you are always getting Error 43 in device-manager. As seen on the screen here.

So the point is to enable the iGPU and disable the dGPU under Win8.x to get a working x1.Opt setup. The way of just disabling the dGPU via Setup 1.x is ending up in freezing and you have to restart the notebook. So I tried a lot of things with Tech Inferno Fan. So many things and I was close to just give up all. But then he had the great idea to just disable the PCI port where the dGPU is connected on. And that's the way how it's working :)

Let's get started:

1. You need to buy the Setup 1.x from Tech Inferno Fan. Here you will get more information about it.

2. Install it as mentioned in the email.

3. Then navigate to "C:\eGPU" and run the "eGPU-Setup-mount.bat" batch file to install Setup 1.x. Now you will see a new drive named "DIYEGPUIMG (V:)"

4. Go to "V:\config" and just replace the "startup.bat" with my startup.bat startup.zip. (It's just to make the whole process easier. It's configured by Tech Inferno Fan and optimized by me. So it's easy and fast to boot up.)

5. If you have done this all correctly you should get an option "DIY eGPU Setup 1.30" on startup. (When not make you sure you missed no step or done it wrong.)

6. Select the Setup 1.30 and run the "automated startup" (You are now using the startup.bat you have downlaoded an replaced with the stock.)

7. Some lines will now come up and then you get an message that your eGPU isn't connected. Just power on your eGPU (PSU + PCI adapter. Make sure, the switch shows "ON") and connect the mPCI adapter to your notebook.

8. If done correctly you now should be back in the selection menu where you can select Windows 8.x or the Setup 1.30. Now select Windows 8.x.

9. Windows is booting normal and you should see your desktop. (If not -> make sure you did everything right.)

10. Go to device manager and you will see two new devices. Click on install drivers and wait until it finished. (eGPU driver took about 10 minutes so don't be impatient.)

Important: It can happen that you get an bluescreen while installing the iGPU driver. I don't know why, perhaps because it isn't connected to the LCD. When this happens just start at point 6. and go on.

11. Now download the graphics card driver that is compabtile to your graphics card. Uninstall your old driver and install the new one. (You can do this step before starting with the eGPU but I don't think there is any difference in doing this after.)

12. When you have successfully installed your Nvidia driver now it's getting tricky but still such simple :)

13. Go to device manager and select "devices on connection" (German: "Geräte nach Verbindung") and search where the dGPU is connected on and just disable it. (I got an blackscreen and I needed to restart my laptop via the power button. But it doesn't matter you need to restart your notebook anyway to get fully working x1.Opt Setup.

14. After restart (just like point 6. you can check the device manager and you should only see the "Intel HD Graphics [iGPU] and your video card that you bought. In my situation the GTX660Ti [eGPU]. (If not -> check the steps above.).

15. You should now have a fully working (expect the internal screen isn't working) x1.Opt Setup. You can check this in the Nvidia cobtrol panel by checking if the "High-performance Nvidia processor" is available. Or go to GPU-Z and check it there.

Manage-3D-Settings.png

16. At the end you can run 3dMark06 or other benchmark tools to compare your results with others. Or just play a game and enjoy it :)

Here is my 3dMark06 score. With the same notebook you should get similar results. (+/- depends in you graphics card.)

Something else to say:

There are some downsides of using the eGPU Setup with an Aspire 5742G. I'll list some of my established.

  • Need of removing wifi card
  • You need to plug the eGPU in after running the automated startup. Otherwise you'll running into reboot loop.
  • You are not able to go into sleep mode and wake up successfully (biggest downside for me)
  • You won't get the full graphics power as on an desktop computer

If you have any question or you think I forget something - feel free to ask me. :)

Wow that is one comprehensive review on that PE4C setup I am looking to build as only now I quite understood all that is required to start off with this experiment!

Thanks buddy!

The way I see it I will be doing the same ways that you have demoed and setup.

Thank God the PE4C V2.0 is such a beauty to miss, I will get all things gathered hopefully in the coming months.

Can you do us a favor? Do you mind posting images of your setup mate?

Regards,

Jes

Hi there,

really appreciate your work.. it's a good review and guide.. I'm thinking of doing the same thing on my old laptop.. Acer Aspire 4752G late 2012, processor i5-Sandy bridge 2.4Ghz, ram 4gb, windows 7 ultimate, iGPU Intel Hd 3000 with Optimus enabled Nvidia Geforce 610M.. I don't have any idea if it would work.. maybe you can give me some advises or walkthrough? since this is my 1st time.. i would be thankful for now as I found something good to do with my laptop.. hope it will work.. anyway, thanks again!!! :smug:

Hi !

Thanks for the description. People who have 5741G/5742G... etc. Did you modify the BIOS to access some options (disable dGPU) or something like that ? It's not mentioned in this thread.

Thanks

Hey guys, I have to apologize for not answering your questions.

I wasn't active in this scene for a while because other things had priority in the past.

Sadly I have to tell you that I switched from my old Aspire 5742G to the new impressive iMac 5k.

Also I couldn't find any pictures of my setup although I thought I took some.

Unfortunately I can't give you any Benchmarks or average fps details of any game.

As the fact that I haven't done anything in this topic for a while I can't give you any advises for your own build.

I still know that i modified my bios to get the i7-640m running. But I think that was only needed because I bought this notebook with an i3-370m which didn't have the Turbo-Boost.

At the end I want to thank you for your good feedback.

If you have any questions feel free to ask me. Hopefully I'll be able to answer them.

hi guys, I have a 5742G with 540m, windows 7, a BEAST v8.4d and a GTX670.
When I connect everything and I turn on the laptop screen remains dark and the adapter for the GPU turns on a green LED.
Is there an easy way for this to work?
thank you so much

No you will not but you will lose Optimus technologie. In the first Gen. Intel you'll drive better with the i7 640M.

I did this setup a long time ago so I can't say exactly what's wrong but there must be something wrong with your configuration.

 

 

Sorry for the late replys but I wasn't able to work on this project due to lack of time.

Now I am working on a new project with a Dell ThinkPad T420.

      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:
       
      http://forum.techinferno.com/enclosures-adapters/8441-%5Bguide%5D-switching-atx-psu-using-paperclip-trick-swex.html
      http://forum.techinferno.com/enclosures-adapters/9426-220w-dell-da-2-ac-adapter-discussion.html
       
      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.
       
      Steps:
      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,
       
      I want to share the modded Bios I created for the Acer Aspire E5-572G notebook.
      The official bios 1.09 was used as a base.
      I'm offering three flavours: Microcode 01, Microcode 07 and Microcode 21.
      Microcode 21 is the latest available microcode, this is the Bios you want to use unless you want the special properties of the other microcodes.
      Microcode 07 is the latest microcode that allows using the full turbo clock speed on all cores (using single core turbo with all cores).
      Microcode 01 is the one you should take if you want to try this. I wasn't able to get it to work on mine (i5 4210m, HM86), but your mileage may vary.
      In case you want to always use an older microcode, I'm offering a script for windows that'll keep the OS from using a newer microcode (compatible with Windows Vista to Windows 10). Frequency and other things can be set up with ThrottleStop (use the latest version).
      I've also included an overclocking enabled ME firmware that should (hopefully) allow overclocking on the HM87 equipped notebooks.
      There are two flavours of this notebook available: Ones that use the HM87 chipset and others that use the HM86 chipset. Overclocking is only possible with HM87 as HM86 isn't capable of overclocking (tested it myself).
      Additionally I offer a collection of Bios, EC, ME and FD files of this device, in case anyone wants to experiment with these for a bit (EC Modding, etc.).
      I will update this bios in case there are newer parts available.
       
      Any feedback is welcome!
       

      Features:
      -Advanced Bios Options unlocked (Advanced, Power tabs and additional options in the existing tabs)
      -Nvidia 840M/940M VBioses replaced with adapted 940MX VBios with unlocked TDP Limit, unlocked Boost Table and some OC (1306,5MHz GPU/1070MHz Memory - with general usability in mind) + all voltage sliders unlocked
      -Intel Management Engine: Updated to 9.1.37.1002 + All Locks Unlocked + Overclocking Enabled For HM87 Notebooks + PAVP (Protected Audio/Video Path) Enabled
      -Flash Descriptor unlocked
      -Microcode updated to version 21 (respectively downgraded to 07 and 01)
      -Intel GOP Driver updated to 5.5.1033
      -Intel VGA Bios updated to 1042
      -Intel RST OROMs updated to 15.1.0.2545
      -Realtek Lan OROMs updated to 2.037/2.64
      -Applied a few useful BIOS patches by CodeRush (Unlock CPU Power Management Register (useful for Hackintosh Users)/Disable BIOS Lock/Disable SMI Lock)
       

      Flash procedure:
      1. Copy the BIOS file to an empty and with FAT16/32 formatted usb stick.
      2. Unplug the AC adapter.
      3. Remove the battery of the notebook - you can unlock the battery on the backside.
      4. Plug in the USB flash disk.
      5. Press and hold <Fn> and <Esc>, and then plug in the AC adapter while still holding <Fn> and <Esc>.
      6. Press the Power button. You can now stop holding <Fn> and <Esc>.
      7. The BIOS flash should now begin, the fans will spin up at max speed and the power led should blink. It should take between one to two minutes.
      8. After everything is done, you can reinsert the battery and go to the BIOS (F2). There you may want to change some settings (the BIOS flash erases all previously chosen settings).
