Noob friendly guide on how to setup EGPU + DSDT. & GeForce GTX 1050 TI FIX!

Recommended Posts

Ok, a little background. I have a lenovo L420 laptop and bought an EGPU adapter via Express Card. I used a Geforce GTX 1050 TI

In order for this to work you need to first disconnect any egpu external device and perfrom DSDT override to your system.

Very easy guide thanks to user 'angerthosenear' found here (JAVA MUST BE INSTALLED IN ORDER TO RUN .BAT FILE. Other wise nothing will open)

Keep in mind step 5 on his tutorial was a bit off. The correct code should look like this:

DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,
   0x00000000,         // Granularity
   0x000A0000,         // Range Minimum
   0x000BFFFF,         // Range Maximum
   0x00000000,         // Translation Offset
   0x00020000,         // Length
   ,, , AddressRangeMemory, TypeStatic)
										/*above this line is only for reference. only copy below*/
QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,
   0x0000000000000000, // Granularity
   0x0000000C20000000, // Range Minimum,  set it to 48.5GB
   0x0000000E0FFFFFFF, // Range Maximum,  set it to 56.25GB
   0x0000000000000000, // Translation Offset
   0x00000001F0000000, // Length calculated by Range Max - Range Min.
   ,, , AddressRangeMemory, TypeStatic)

Restart your computer and confirm your DSDT override worked by going to Device Manager -> Resources by Connection -> Memory and you should see a hierarchy for 'Large Memory'

When I was at this point I was still getting error 43. I thought it was a driver issue, but ****** via email thought it was a timing issue with clocks so he suggested I 'Jumpered' the powersupply so it would constantly stay on as long as it was plugged in. So when I plugged my expresscard in the laptop, the GPU would already be powered on. I would first plug your EGPU in your system and see if you still get this error. If so, jump the power supply unit by grounding the greenwire with either of the black wires to the right or left of it. This can be done in many ways, be smart about it. Try to make it reversible. Don't be like me and cut it, splice it, and jam in behind the ground wire. It works, but, not very pretty. 

This should get yours working. Unless you have a 1050 TI, if so, read on.

 

Download driver versions  372.70 and 375.63 and extract them

 


1:) - Open the INF for 375.63
Extract the drivers you want to modify using something like 7zip. (with 7zip installed, just rightclick
and press "Extract to "/File name here"")  
Inside the extracted driver folder open Display.Driver.
The "nv_dispi.inf" in that folder is what we need to modify. If you can't find nv_dispi.inf, look for
"nvts.inf", "nv_dispwi.inf", or "nv4_dispi.inf" instead.

2:) - Your GPU string
Search (CTRL+F) for your gpu '1050 TI'

Copy these lines, should be 3 if I remember correctly

3:) - paste them in the appropriate place on the 372.70 INF file

4:) install 372.70 Drivers and restart

5:) Now, your error 43 should be gone but your GPU will run like dog sh*t. You need to install drivers 375.63 EXPRESS INSTALL ONLY. If done correctly you will not be prompted to restart.

 

Congratulations, you're done. Took me 3 days to figure this out. If an idiot like me can do it, so can you. I will gladly answer any questions

Didn't work for me. I modded the 372.70 drivers yesterday out of desperation and like you said, it runs like ****. At least it worked somewhat and proved my system is capable of running an eGPU. I saw this post today so I tried to install 375.63 with express install and also through device manager; comes up code 43 every time.

      Hello guys ...

      i wanna make sure that everything is going to work fine with my laptop so i got some questions

      First of all my laptop is Lenovo Z51-70
      CPU: I5-5200U 2.2ghz
      iGPU Intel HD 5500
      dGPU:AMD R9 M375
      Ram: 8GB (will raise it to 16GB)
      HDD: 1TB stock one
      SSD: 120GB (for my games and windows only)

      now i investigated  a little about eGPUs and found that i need a M.2 or thunderbolt, i've found that my wifi card use a M.2 a/e key aka ngff, so i will be using the GDC Beast NGFF version

      to the bad part / question part

      What do i need to know other than the stuff above?
      what is the white-listing thing? i found on support forums that my laptop support some wifi cards only and it's bios cann't be modified according to bios modifying forums (not here)
      in same time saw some posts on reddit that says if ur bios have UMA graphic option then you will need to disable PAX / WIRELESS and enable UMA and it will work fine, the question is that true?

      i wasn't able to find anyone who did it on Z51-70 i found only 1 post on reddit for Z41-70 (which after research found that both are using same M.2 a/e key slot and also same bios... but the one who posted only replied that it's recognized with some errors and never replied back with any updates so still not sure about it.....

      Hi, just a quick question what would be the best EGPU adapter, because i see the really expensive ones but then you have the 400$ dollar one that Lowspecgamer used. Which do you guys recommend ?

      Is it possible to unlock bios on that model? Please help me with it if somebody can.

      The computer I used was '' Lenovo Y510P ''. There is a '' Nvidia GT755M [SLI] '' as a display card. I have tried both ways of downloading the video card driver from both GeForce Experience and Nvidia driver site. Both kinds of graphics cards are starting to update. Later, the 'graphic driver is installed' part of the screen goes and never comes again. I can not enter Windows when I turn off the computer. I have to take format from scratch.

      After formatting, Windows automatically loads a graphics card driver in 2017, trying to update the driver again, it stays black on the screen again. I have to format again.

      With DDU (Display Driver Uninstaller) program, I deleted the old video card driver and updated it again. But I met the same problem.

      I communicated with Nvidia and stated that I had such a problem. They asked me not to install the 388.13 video card driver. That graphics card driver has been loaded without any problems. But I have the same problem with all the video card drivers out there.
       
      NOTE: This problem only happens on Windows 10. I can update the display board without any problems in operating systems like Windows 8,8.1.
       
      NOTE: I have been having this problem for about 2 months, before I could update my display card in Windows 10 without a problem.

      The driver I am currently using is: 388.13

      Recently obtained myself a bricked Y410P after undervolting my CPU, using svl7's bios mod on TechInferno. If you only take one thing away from this post, it should be the fact that 
      NEVER SHOULD YOU EVER UNDERVOLT A LAPTOP CPU FROM A MODDED BIOS. Hindsight is never 20/20.
      Anyways, back to topic! 
       
      I went and purchased my self one of these, in hopes of to re-program my sad bios. So far no good. 
       
      I am wondering if anyone out there have had any success with this approach. Please share your journey here!
