Asus G75VX eGPU... Need Help! Running over TB1 using Sonnet Echo pro Expresscard adapter and PE4C.

Recommended Posts

I bought this thingy-mabob so I can try an egpu build. It's an Sonnet Echo Pro Adapter. what it does is it able to connect to expresscard devices over thunderbolt. I bought the Pe4c (which is the thing to put your gpu at) and I put in an old gt 640 (yes it works). I crossed my fingers AND I prayed but all this shit does is make the fans spin at like 1000rpm (I got a nice little personal fan now). I tried updating BIOS and disabling dGPU I even fresh installed my computer (goodbye porn :() Anyway, I wanted to do this because in the long run, it would have saved me money instead of buying a new computer. All I would have needed to do was buy a new gpu and BAM! 4K gaming. But if anyone wanna help my sorry ass, please do so. I wanna play BF1 but 4 year old gpu is crap. Please anyone with knowledge of this subject or maybe even the legendary Nando4 can help. Thanks.

join the club bro. g75vw with vx's bios & 670mx (instead of 670m) here , but over mPcie/beast.

if you make it work...let me know please what you did.

mine doesnt have issues over mpcie, it detects the card, but refuses to use it. 

sadly,i see the forum is kinda dead for now...prolly most ppl are thanksgivingin' for now. expect slow replys, from what I am seeing also.


ps: this seems to be your problem: 


  • Upon powering my eGPU, the fan on the eGPU just spins faster and the card isn't detected.

    This indicates the eGPU is either not on the PCI bus or isn't getting 3.3V. Try unplugging, replugging the mini HDMI cable (expresscard solution) or hotplugging the PM3N (mPCIe solution). If the card is still not detected then connect the setup to another system's expresscard slot. It may be either a faulty expresscard slot or mini HDMI cable. Worth testing the eGPU in a desktop system as well. 
  • I have problems running an Nvidia eGPU with an internal NVidia dGPU (supplied by nlooije/Khenglish)

    The trick is to get both an NVIDIA dGPU and eGPU working work under the same driver.

    This method assumes that the eGPU is detected in the device manager. If any errors such as code 12 or 43 are present check the corresponding items in the Troubleshooting section. If using the PM3N and it is not detected then maybe the mPCIe port is whitelisted, use the Setup 1.30 to unwhitelist.
    • Download the latest drivers from the NVidia website or from this post by Tech Inferno Fan.
    • Once the eGPU is detected, windows will automatically search for drivers through windows update. Cancel the search, and let windows install the standard vga drivers.
    • In the device manager, right-click uninstall the dGPU and eGPU NVidia drivers. Use CCleaner to search for any residual Nvidia driversoftware and delete further.
    • Install the latest Nvidia drivers. If everything went correctly then the installation software should ask permission to install the drivers twice, once for every card.
    • Reboot and cross fingers.

here's the  troubleshoot thread:

Thanks Darkthor. But I'm probably going to just get an ugly ass alienware and plug up that alienware amp thing to it. I don't want to fuck up my laptop and not be able to sell it. Damn, this is going to cost some money. Guess I'll have to skip paying for rent this month :\

My recommendation is to hold your horses....cause it can work,and be cheap.

I doubt thunderbolt would have any problem, since tbolt is better than mpcie in terms of issues. And since I've set it up in terms of issues, and FINALLY  WORKS i recommend you guy a gtx 980 ti, with a PSU...and fire that baby up cause it will work!



quick update:


Got it working.



my setup:

- asus g75vw with 670mx  (from a  g75vx- and I modded its bios)

-beast exp gdc - <30$.  beast mini PCIe version v8.4D

-DELL DA-2 220W input for beast adapter.


-gtx 750 ti from MSI  (ANY card BELOW pascal 1050, 1060 and 1070-1080  series) that uses a driver BELOW 372.70)




ORIGINAL firestrike:



NEW firestrike: 





didnt need setup 1.30

Windows recognised it INSTANTLY


plug and play LITERALLY.


Steps to install it:


-Plug it in on mpcie

-turn windows on.

-install DDU display driver uninstaller - uninstall ALL nvidia drivers.

- reboot

-install  your new EGPU driver ( beware! install the older drivers BELOW 372.70)


-install your dedicated gpu drivers

-reboot again

-watch and be amazed on how your new egpu works: try gpu-z on both gpus, on egpu you should see core clocks...and then go in nvidia control panel in start menu (not gfe experience) and set up your gpu preferences.

Damn man! Good shit! But I already agreed to buy the disgusting alienware laptop. Also, I tried following your steps but it didn't work. Guess I shoulda bought the mpci-e version. But how's the game performance compared to desktop version? It should be around 70% right? And it sucks u can't use pascal gpus.

      I have tried to update nvidia drivers of my notebook ge72vr6rf apache pro. The only drivers that works are the ones provided by the msi. The problem is that they haven't updated those since 2016 and I can't play newer games. 
      Some say you need to mod your 1060 drivers, which I have no idea how to some says you need to update the flags in ini files. So please help me
      Thanks for your time.

      I have a notebook Asus X550CC.
      Some weeks ago my screen went black with the brightness working though (black screen but one can see brightness changes) - I couldn't figure out the root of the problem, since it was sudden and it works with an external monitor.
      Now, I was trying to install an SSD with a caddy. I went to BIOS to change the boot order, but couldn't find my SSD - so, I accidently disabled launch CSM option hoping it would recognize it or something. After that I couldn't access BIOS anymore and I have a very slow startup with dxgkrnl.sys, wdfilter.sys and CAD.sys showing not loaded in the boot log.
      I tried to:
      Remove CMOS battery for 8h  Short JRST2001 and JRST2002  Access BIOS through windows 10 troubleshooting None of the above worked for me
      The laptop does not restart or shuts down correctly as it gets stuck somewhere and I have to press ON/OFF button again in order to shut it completly. The only display I can see in the external monitor, during start-up is the windows 10 loading screen (can't see the asus loading screen) and it takes more than 5 minutes to get me there (seems like a bootloop).
      I hope someone may have the answer cause I'm running out of solutions 
      Thanks in advance, everyone!

      So, i got a strange situation here. I have an old Asus ROG G751JM laptop connected to an old Samsung monitor (Model S20C301L) through a VGA connection.
      This monitor supports both DVI-D and VGA inputs, while my laptop can output through VGA, HDMI or Thunderbolt/Mini DIsplayport. I wanted to upgrade to digital signal, so i bought an Thunderbolt/Mini DIsplayport to DVI cable.
      At first, it was a nightmare. There was absolutely nothing i could do to get it to work. I spent hours troubleshooting, but the monitor just could not detect any signal, only VGA one. But then this happens.
      I was testing with only one connection at once and i got tired of plugging and unplugging the cables every time. So i had the idea to keep both cables plugged in and change the source detection in monitor's menu when i wanted to. So, with the TB/MiniDP cable already connected, i've then connected the VGA cable (while DVI was selected as input source). The display started flashing. After 2 seconds, voilà, it was working. And i was like, "what the f***???" I've then unplugged the VGA cable, signal lost. Plugged it again, got digital signal.
      Well, i'm happy that it's working now, but i simply don't understand what's happening here. Why is that i need both connections simultaneously to make it work? WIll that still happen if i use a HDMI to DVI cable?
      Fun fact: the image displays only after windows startup. So, if i want to enter BIOS setup for example, i need to switch back to VGA as input source.
      Sorry for my english.
      Update: Can't run games with It, i get bsod.
