Blackscreen/not Detected eGPU on Acer Aspire V3-772g

Recommended Posts

Hi Guys,


I hope I'm posting this in the right section and yes, I used Google, the search function and the troubleshooting guide.


I'm trying to get an eGPU setup up&running but I encountered some major problems.

First of all, here are the specs for the hardware:



Acer Aspire V3-772G

CPU: Intel Core i7-4702MQ, 2.2GHz - 3.2GHz boost

dGPU: Nvidia Geforce GTX 760m




PE4C-PM060A V3.0 (via mPIC-E)


PSU: Cooler Master B600 Ver.2 - 600W/+12V/PCI-E

GPU: MSI Geforce GTX 970 4G - 4GB vRAM


I don't really know where to start, so lets begin how everything is connected.


The Acer-Aspirve V3-772G has 2 mPCI-E Slots. Both were previously occupied (SSD MMC, and an Wifi-Bluetooth card in the half/small port). I tried the following steps on both mPCI-E slots without any changes.


For the first try, I just removed my WIFI card and connected the PE4C to my laptop. Next I inserted the new GPU and connected the power from the PSU (1x24p ATX directly from PSU to PE4C, 1x6pin and 1x8pin from the 6/8p output from PE4C to the graphics card).

On the first boot, nothing happened, the screen stayed black but the gpu-fans started spinning and the status-leds switchted to green, so I tried different troubleshooting steps.


  • Different boot-delay settings for the eGPU - made no difference, the screen stay always black (no signal) but it seemed to result in different fan-speeds on the gpu

My next steps seemed to work at first, because the GPU-fans started spinning really fast, without any crashes or "not working display". But in every case, neither the GPU or the PE4C could be detected by windows.

  • Turn eGPU ON when windows initializes
  • Turn eGPU ON after standby (booting with eGPU OFF)
  • Hot-Swap WIFI and eGPU (from standby - with and without wifi card on boot)

After this, I completly removed the nvidia drivers (for mobile) and deactivated the dGPU via device-manager and repeated the above steps (hot swapping...) but with the same results. Either it halts on boot with "no signal" or it doesnt get detected at all.


After further research, my next guess was that the dGPU messes with the eGPU on startup, so I bought eGPU Setup 1.30

  • After making a USB-Bootable drive, I booted the setup "with menu" 
  • First, I booted with the Wifi-Card, wich worked fine (detected) and gave me the pcie port, where my eGPU should be setup.
  • After this I continued with the previous steps (turn egpu on at boot, in menu, hotswapping...)
  • With each variant, (after disabling the dGPU) I tried to initialize , reset, deactivate/activate the correspondent pcie port - including different gen setups.

The result stayed the same as in Windows, the eGPU won't get detected in eGPU Setup 1.30 (the pciport shows nothing after his id -> pci3 1.2x:    )


Now I am out of ideas and wonder if I am just doing something completly wrong or the eGPU Adapter is simply not working with my laptop.


Of course I researched before buying the equipment... which should work fine with my laptop...

I also can refund my GPU (today or monday) but would prefer not to :)


I appreciate every helping hand, who can give me a clue how to fix this.


cheers, d00t3y

Yes the same things append to me.




I really like the idea of the eGPU so I decided to bought one.


My laptop: Asus x53sc

CPU: i5-2430M


iGPU: HD 3000

dGPU: Nvidia GT 520MX

OS: Windows 10/64bit


My eGPU setup: EXP GDC v8

eGPU: Nvidia GT9600 (for test if it works i'll buy the Nvidia GTX 950)

Power: 550W


My story:

  1. I bougth the EXP GDC v8.
  2. I connected all the cable correctly.
  3. Windows 10 started with no problem.
  4. I saw the eGPU in the Device manager.
  5. I downloaded the driver and installed it with out problem.
  6. But at the reboot the internal monitor was black and the eGPU doesn't have any output video.
  7. Now :(


What i try to do:

  1. I try to disable the dGPU form the device manager.
  2. I try to reinstall the GT 9600 driver.
  3. I try to follow: https://www.techinferno.com/index.php?/forums/topic/8947-mpcieec-egpu-troubleshooting-steps/
    1. I uninstalled clearly the Nvidia GPU driver and I cleaned the registry with DDU but the problem persist. (black screen)


Possible solution:

What is the problem? Where i do wrong?

Do you think that i need the Setup 1.30 SW?

The problem could be Win 10? Should i return to Win 7?

( Your help <3)

If the delay switches does nothing and bios hangs on all settings then try to isolate PIN22 on the mpci connector and set the PERST delay switch to max. Hope this solves your issue. Btw if you are using this pin22 method never restart you computer, always do shutdown/power on.

Hi Guys,


sorry I was quite busy lately, but here is my final conculsio:


Unfortunaltey I didn't get it to work "in time" so I decided to cut my losses for purchasing the board and DIY eGPU Setup tool(although it's a mighty tool, it didn't make a difference in my case, because the problem, at least i think, was "on a level above") and refunded the gpu itself.

For more info: 



Thanks for your help, but unfortunatley I wasn't able to try this in time, but maybe this does the trick.


Another reason why I decided against it, and is clearly a problem of this specific board:

The mPCI-E adapter (especially the fixed/attached cable to the pcb) didn't quite fit in the notebook caseso the connectors sat at an angle and needed to be taped down. Also the backplate was a mess with this adapter as well, half open and not really stable and because it is right in the middle, the notebook easily tips over from left to right (of course I used an usb keyboard, but if you have a cat or some other pet...)


My last resort was to bend the cable right after the pcb connectors so that I could screw the hole thing down in the slot, but it made no difference (tried everything with this "setup" again").

In my oppinion, when you don't have an PCI-Card slot or some fancier thunderbolt stuff for "plug and play", this whole thing defeats the purpose of itself, because you have to screw/unscrew everything everytime you want to use your "mobile" notebook somewhere else - and i don't think you should stress your motherboard with this "heavy mechanical use".

On the other hand, you could use this to "retire" a notebook as an "desktop" with a fix spot at home - which is not really an option for me.


So here some stuff that I tried after my initial post, so you don't have to do it again (keep in mind, that this only applies to the same board and gpu)

- flashed insyde h20 v1.15 unlocked BIOS on my notebook

- tried different dGPU/PCI-E BIOS settings and/or deactivated them (then the whole procedure with hotplugging and all that stuff)

-I even tried to deactivate the whole iGPU and dGPU, which is of course a bad idea (I just wanted to try everything) because you can't see anymore ;)

-NOTE: before you try stuff like this, make sure to check the hotkeys for "set to default" and "save and exit" in you BIOS and how you can confirm this two options (just enter,left+enter, y/n,...) so you always can restore your BIOS settings to default, even when you deactivated the wrong thing and cant see anything. (it certainly doesn't help with anything, but can save your a**... in my case it was F9-Enter, F10-Enter)

-Different UEFI/Legacy settings with windows and linux (for DIY eGPU)


hope this helps, so you don't have to waste time and/or money


cheers d00t3y

Error when trying to PM you so here is my issue. Kindly assist


Hi, I saw your post saying you'd found a fix for the acer egpu laptop. Kindly assist me

I have the gdc exp 8.4 and an nvidia 970. Laptop is the acer v3 571G with i5-3210m and dedicated nvidia 630m.

When connected, the gpu never appears on my device manager. It only appears very briefly on the diy 1.3 software screen and this only happens when i am trying to fit the cable into the mpcie slot.

      Hello all! Im posting this here in hope to receive some orientation or help regargind my egpu project.
      I have my old and trusted Acer 5750G and I’m still using it everyday for work. I’m a photographer and it has worked quite well with some upgrades:
      -Upgraded i5 to i7 2630qm.
      -Upgraded ram, 8gb to 16 gb.
      -Upgraded HD to SSD.
      Some facts:
      – I have the unlocked bios so I was able to set the mpci port as “hot pluggable” and I can also deactivate the dedicated nvidia 630m from the bios itself.
      – I have bough this case [PCIe PCI-E EXP GDC External Laptop Video Card Dock / Laptop Docking Station (Mini PCI-E interface Version) ] that will arrive home in 10-15 days.
      – I have ordered a wifi usb card.
      I was thinking in getting a nvidia 1060 6gb and plug it to my old laptop using the mpci port. I ask for your advice and knoledge regarding this:
      1- Is this a good card choice?
      2- Will I face any problem with my setup or there is something important I should take into consideration?
      3- Will software that uses CUDA (photoshop and premiere, for example) get reinforced with the new card?
      4- How much processing power will get lost for the “small” port I will be using?
      Thanks a lot again, and sorry for my english mistakes!!

      Dear all,
      I hope someone can help me out here.
      I have an Acer Aspire E4-471g Laptop. Intel Core i5-4210U NVIDIA GeForce 820M 16gb DDR3 RAM 512GB SSD
      I have an EXP GDC V8 Beast eGPU adapter. I use a power adapter to juice my eGPU by Dell Netzteil ADP-220AB B 12V 18A 220W P/N Y2515 REV A02
      I have a Zotac GeForce GTX1050ti 4GB
      The Problem:- I did the normal procedure, disable the eGPU. Took out the wifi and replace it with the mpcie cable.
      Switch on the computer and I have a blank screen. No screen at all on the laptop screen nor in the external monitor.
      Is there a best solution? I have seen the Setup 1.3 but I will do that if that is really the necessity.

      Hi everyone,
      I hope I'm not going to write off-topic;
      I own an Acer Predator 15 (G951) notebook, and it never gave me problems before; I've never used the integrated audio jack port because I usually listen to music and other stuff through Bluetooth headphones, but few weeks ago I noticed that putting a jack connector in the jack port only deactivates the sound from the pc speakers, but the headphones don't appear in the "devices" section, and the sound coming out from the headphones is really faint and distorted (only if the system slider of sound is at the maximum level and the sound should be very noisy, when the level is lower I don't hear anything at all). Also, when I put a jack in the microphone jack port of the pc I hear the classic sounds of the jack which touches the pin connectors inside the port, but it doesn't happen with the headphones port. I tried almost everything: I changed a lot of headphones, both phone headphones with a single jack and pc headsets with two jacks (for the headphones and for the microphone) but every time it's the same. I installed and reinstalled a lot of different versions of the audio drivers, both from Acer and the productor (Realtek), and nothing changes, I also tried with Ubuntu and it's the same. What could be the cause, and can the problem be solved without any technic intervention? Anyway the warranty for my pc is still valid, but the assistance should be the very last resource (I should do a backup of everything and format and so on). And, the last question, I flashed a custom VBIOS some time ago, does this compromise the warranty? Should I really reflash the original VBIOS or it's not so likely they're going to check on this?
      Thank you all for your attention!

      Hey, there. Few month ago I bought this laptop and it’s awesome, though it has some cons. I’ll describe everything in this thread. Also I’m searching for someone, who will share his time and help me crack its’ bios

      Acer Predator G9-593

      Intel Core i7-6700HQ (2.6Ghz/3.5Ghz) (https://goo.gl/dehk14)

      Nvidia GeForce GTX 1070 (8Gb GDDR5) (https://goo.gl/z2aEFL)

      15.6inch 1920x1080 (G-Sync) (IPS) (Matte)

      16Gb DDR4-2400 / PC4-19200 (2x ACR24D4S7S8MB-8)

      1tb HDD + 128gb SSD

      Windows 10 x64

      Nvidia driver - 378.49

      4 USB 3.0, 1 USB-C с Thunderbolt 3, HDMI 2.0, Display Port, SD Card reader, Gigabit Ethernet, Audio/mic

      Several reviews:


      Also this laptop has a bigger brother – Acer Predator G9 793, absolutely same laptop but with 17inch panel, 4k variant and 4 speakers.

      First of all, good sides:

      Solid construction, soft touch martial all over the case, no glossy parts.
      Sound is really loud, even basses exists here, though I can’t say its best of the best.
      Outstanding performance, take a look at this data https://goo.gl/oyF9dl, almost all games run over 60 fps in 1080 and over 30 fps in 4k. Take a look a several gameplay videos that I’ve captures on this beast, all of them were captured in 4k resolution, on ultra settings with no AA:

      Rise of Tomb Raider - https://youtu.be/rNRMnytsC2c
      The Witcher 3 - https://youtu.be/dJicr6we0z0
      Quantum Break - https://youtu.be/PNofDssIgS4
      (1080 with max AA) Crysis 3 - https://youtu.be/H1ja_BhD0-Q
      Resident Evil 7 - https://www.youtube.com/watch?v=LiF-zhTwNDE
      Battlefield 1 - https://www.youtube.com/watch?v=ypOEnJ9KbKs
      Dishonored 2 - https://www.youtube.com/watch?v=Jhtvj4BkiMc

      Only in  Ghost Recon Wildlands I had less then 30 fps https://youtu.be/lbeW9PZvsUo

      And bad sides:

      Thought laptop is 15inch, its bulky as hell, thank god it looks okay, not like some previous gaming crap lappys: http://www.notebookcheck.net/uploads/tx_nbc2/toshiba_qosmio_x305_q725_01.jpg
      Screen has some ghosting, previous static images can stay on screen for some time. Not this laptop, but image illustrates the issue: https://goo.gl/H42OCJ 
      Some laptops has overheating issue on CPU. Though in rarely influence on performance, its still sad thing to have in such big laptop. Issue described in this thread: https://goo.gl/KjNNBN, simple CPU repasting solves the issue: https://www.youtube.com/watch?v=DVEpuZNWLxw
      Stepback in turms of battery life since g-sync laptops doesn’t support nvidia optimus. Around 4-5 hours of work.

      Hollo, It's my first post. Few weeks ago I made setup:
      Acer Aspire V3-772G
      i7 4702MQ, 4 cores 2.2 ghz.
      8GB DDR3 ram
      1 TB 5.2k HDD
      120GB SSD
      Windows 8.1 works on SSD
      BIOS InsydeH2O 3.7 fully unlocked
      My external setup :
      EXP GDC beast v7
      GTX 1060 6GB MSI ARMOR
      600W PSU
      please note my PSU and GPU is completely new.
      I can play games very well, however games randomly  crash it takes from 5 to 40 mins to crash. Also I noticed crash sometimes happens not playing anything, desktop turns black. That's my only problem and I can't find a fix. Also please not after crash Windows recovers quickly.
      what I have tried :
      - Because Acer has no white list, I have unlocked BIOS and disabled dGPU, after that everything started to work. Please note my dGPU is broken, can't do any 3D render for some reason...
      - I have tried few different versions, like Windows 10, windows 7 and Windows 8.1. Now currently I'm using Windows 8.1 it seem to give best performance.
      - Nvidia drivers I have tried is only few versions, however game still crashing.
      -I haven't tried 1.30 setup that much main reason is that, I don't really know what to do there and also can't start Windows after configure.
      - Mainly I'm testing on GTA V, however I've tried different games like Tomb rider or wither 3.
      - Also played with EXP GDC v7 switches, these makes no effect at all.
      - switching to gen1 in bios also made no difference. I only receive poor performance in games.
      - I have also done cpu monitoring all seem very perfect. No problems with power and so.
      lastly, I'm waiting for any help what I could do with my setup. Also you can ask me for any information I'll be happy to provide it.
      please help me to fix this problem.
