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'm happy for now, a 980ti is in the works soon .it'll blow the roof , definetly.

      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?

      A part of my BIOS got corrupted that controls my laptops backlights. Other methods like the Gary Key fix did not work for me because I do not get any light up during post. i followed this guide  that says I need to extract and use the 6MB portion of an 8MB bios dump, only AFUWIN tells me "Error, ROM file size does not match existing BIOS size which is because my laptop BIOS size is only 5.87MB.  I don't need to flash the whole BIOS, I only need to flash a portion of it. 
      I've searched everywhere online for a dump of my laptop model but non exist that I know of.

      I fiddled around with modding my laptops BIOS to unlock XMP profiles and hopefully seeing if optimus could be disabled. After flashing my modded bios and trying it out, I noticed that my keyboards backlight no longer turns on. I was unaware it requires an official BIOS to function. They backlights wont turn on unless ASUS ATK package is installed but now it seems it also needs an official BIOS?
      The modded ROM and tool I used if anyone has any experience with this and doesn't mind telling me what to enable/disable, or anything else i can do to re-enable them
