you will not see two display in the optimus internal screen,only you wil have a transparent option in the nvidia control panel wich alows to use egpu as a preferred render graphics

yeah, the problem for now is that the nvidia control panel is impossible to open. i'll try the WIN8.1 drivers tomorrow and post the results when i do. Thanks for the advice, since my laptop initially came with 8.1 on board it is worth a try.

Just tried the 8.1 drivers, and they refuse to install. However they had a folder with installation files for WIN10 alongside the folder for WIN8.1, which installed just fine but resulted in eGPU only working with an external monitor again. 

I'll try installing the old 350.xx drivers, apparently after them Optimus got broken on WIN10.

Alright, modded the 350.12 drivers with the correct lines for my GTX960, as well as downgraded the drivers for my HD4000 to 10.18.10.3621. The internal display is now properly recognised, however the game I was testing froze a few minutes after launch. Working on solving this at the moment.

Also, do you buy chance also use the EXP GDC adapter? If so, is the "ATX PW" switch in the left or right position?

Edit: moved the switch into the left position, things seem to be fine. Now the eGPU and the PSU turn on and off when I turn the laptop on and off. Previous freeze seems to be game-specific. Aside from some stuttering, games are stable to run. Will try connecting to a TV via HDMI to see if stuttering/framerate improves.

ok.look if the pcie link is working on x1.2

I am using pe4h v2.4 wich i had try in various notebook,not gen2 compliance,although remember once achieved in a msi with an i7 Sandy bridge to reach gen2 bandwith.

just put the card under load,and look in the gpu-z for the pci-e link,must be gen.2 according to your setup

gen2 bandwith gives a real experience on the internal screen...

GPU-Z shows that it's using PCI-Express x1 v2.0, so everything's fine there. I'm running FurMark in the background by the way. Stuttering may be a bandwidth issue, since PCI-E is limited to x1.

I am also looking at doing something with same adaptor and similar machine Asus i7 3517U HD4000 (minus dGPU) and eGPU but on Win7. So this post has been very helpful, I appreciate the updates.

 

I have seen a guide about just using mobile drivers and "trick" the laptop into thinking your eGPU is your dGPU (owen-lu eGPU guide). I have not tried this yet and not sure if you have, thought I would suggest it.

 

Also when you experience stuttering maybe monitor how much memory the game is using? If it's using all the GFX memory and needs system memory it may be using that precious mPCIE bandwidth to send and fetch the information.  

 

Looking forward to seeing how your setup goes! Gives me hope for my own project.

 

Thanks

Hello, and first of all, you're welcome. As for tricking the laptop into thinking that eGPU is a dGPU, I believe that's exactly what happened. The Nvidia control panel only gives me an array of settings present for mobile GPUs, not the full set, which means the OS sees my eGPU as a dGPU. 

I have read the owen-lu eGPU guide, and considering my setup only worked when I installed 350.12 drivers, it was helpful, but if you open up some new drivers you'll see quite a lot changed in their .inf files, meaning you'll have to do some guesswork, as the guide is relevant for 353.xx drivers.

As for the stuttering, I'll test it more extensively today, including VRAM monitoring, as it seems to be somewhat game-specific (Dying Light being the worst case, and Fallout 4 being somewhat tolerable). Will post once I do.

Update: The framerate drops & stuttering seem to be unrelated to VRAM usage, just tested Borderlands 2 and VRAM never exceeded 400MB, GPU usage is around 60-80%, CPU usage is around 80% at all times. RAM usage is just <4GB. During most of the heavy stutters CPU usage jumps to 100%, so the problem is CPU-related, however when CPu is around 70% the issue is still present. I'm going to test some more.

Edit: Dying Light was indeed having VRAM issues, dropped the texture quality and stuttering is gone.

Update: Tested Doom (2016) today, and it's really weird. CPU usage howers around 30-40%, and framerate is identical 20-35 fps on low, medium and high presets. Performance monitoring shows that it's held back by the CPU, which takes up to 40ms to process each individual frame, while it only takes the GPU about 10-25ms. Tested on OpenGL, as Vulcan seems to prevent Doom from launching. Will try to update drivers while using an external monitor tomorrow. Any suggestions are appreciated, as always.

Those ULV processors have a pretty low speed but high boost clock speed, maybe throttlestop can offer some tweaking with the CPU if it's causing bottlenecks. (Something to do with allocating resources between CPU and IGPU)

 

Glad you've got the internal display working at "playable" rates (ex FPS).  Do you get over 60FPS on your internal display on less demanding games? 

 

Maybe the CPU can't process all those frames (if that's what Optimus technology does) quick enough. Hope you figure it out! 

 

Im getting a 960 4GB hopefully in the next 2 weeks, so I'm hoping I can get mine to work also!

I'll look into it. In my case, the CPU doesn't seem to throttle, as it's sitting at 30%-ish usage and about 10°C under it's regular "fully utilised" temperature, so it's just not being used for some reason. Could be a driver issue, since 350.12 drivers are about a year older than Doom itself. 

And yes, I do get 60fps in less demanding games, I even see stretches of 50+ fps in Dying Light, which isn't particularly easy to run.

Also, the 4GB version of GTX960 is quite a good choice, it's a safer bet than the 1060 in terms of getting it to work. And for now, avoid the 1050's and 1050Ti's, they do not work yet, I learned that the hard way. Traded it for my 960 in the end.

Update: Installed 365.19 drivers (Doom-optimized) without using DDU and without modifying them, and interestingly, everything works now. Doom is running around 35-50 fps on Medium using the internal display, and around 50 quite stably using an external monitor. It crashed my system to a black screen once, which was unexpected. I'll try it some more and post if any crashes happen. Wish me luck ...

Alright, I turned the most demanding settings down a notch (shadows, lighting, reflections) and had no crashes since then. My setup seems to be done at this point, and unless something noteworthy happens, I don't think I'm going to post much. Thanks everyone, and may your stuff work as intended!

Congratulations on getting it to a place your happy with!

 

Thanks for the updates, it will be a great help incase I encounter similar problems, along with getting me excited at the potential FPS boost I could get! 

 

I'm just in the process of ordering my parts, I've decided to go for a Xbox 360 203w power supply through the 8pin into the beastV8 and using the 6pin out on the beast to a 960 4gb. Thoughts?

 

fingers crossed! If it doesn't work it's nearly £200 wasted! :(

Thanks, and as for your setup, the X360 power supply kinda worries me. It will probably work, but since it was developed specifically to work with the X360, it may not be able to properly power a graphics card that was designed to work with ATX power supplies. Not saying that I'll fail, but I'm not aware of it's specs, and I've never seen anyone use an X360 power supply for it. The rest seems fine, and personally I got a PSU that has a separate 6pin power cable for the GPU, however using a 6pin out on the dock works just as well. Hope everything works for you in the end!

      The GPU works, The PSU works, The system works. [individually they all do work]
       
      The system works perfectly fine without the WLAN card.
       
      When i put the system to sleep and hotswap the mPCIe riser and WLAN press something on the keyboard.. Restarts.
      Will shutdown in roughly 27 seconds for those 27 seconds it works just fine like how it normally would on external monitor.
       
      When i shut it down and plug the riser and switch it on, same story. 27 seconds.
       
      I don't even see a error. I get to login screen directly. I used DDU already.
       
      I timed it. no matter what i do if i use the eGPU, External monitor it restarts instead of pause-play. I have 27 seconds.
       
      Need help!

      Hi guys,
       
      I'm sorry for making another thread just for this but I really wanted to pick your brains on this!
       
      I have an m15x with a 770m running windows 7 and everything works. Rock. Solid. I'm pretty happy with it. Since windows 7 is on it's way out, I would like to upgrade to windows 10. Now I've looked into it before and had a really hard time getting the 770m to behave nicely and had all these issues with green/yellow/pink screens and I remember it being a miracle I got it to work on 7 as good as it does.
       
      My question is how well does the 970m install vs the 770m - particularly on windows 10? I would buy it in a heartbeat if it makes the install less tedious with the colored screens and all that. Especially if all the functions work on it! I have been searching the internet and I cannot find nearly as many problems with the 970m as I could with the 770m, or am I just  not looking in the right places?
       
      Thanks a million!

      Questions-
      1 is there any way to get this done without the mod?? 
      2 if mod is the only way... kindly help me with step by step instruction in laymans terms... i m not a techy... so i might not understand technical terms.... altho i am interested... but learning yet. Please help.

      Has any company out there launched a laptop with an external MXM port? 
       
      Just curious since with the boom in the gaming laptop market and some companies launching eGPU thunderbolt enclosures, isnt the MXM faster?
       
      Is it because of licensing issues? or hardware problems?

      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.....
