I know this is a late reply but here goes. My laptop BIOS didn't have a graphic option either. I disabled the AMD dgpu from Setup 1.3. I changed the GDC Beast v8.0 with a PE4C v3.0 because with the GDC the drivers from nvidia were randomly crashing while gaming because it wasn't stable at PCI-E x1 v2.0. With PE4C v3.0 everything is working fine without any issues and I didn't even need DSDT override. Also I upgraded to a GTX 1070 and even though it's not working at full potential the upgrade is very noticeable.

@turilapaSorry for the late reply. I haven't been checking the forums lately. You probably aren't adding every setting/modification you make to the startup.bat. I think you probably figured that out by now but I thought it was worth mentioning.

Nope. I have an intel igpu and amd dgpu and after adding an nvidia egpu and disabling the amd dgpu I can use the internal screen. I could only use internal after getting setup 1.3 and disabling my amd dgpu. Not really useful to me though since I already have an external monitor. P.S. But you need the intel card to work for optimus to run and you said it doesn't if I'm not mistaken. From what I understand Optimus term used here on the forums means running the egpu on internal so it's not really "optimus" the way nvidia means it.

Glad I could help out and it's working fine in Gen2 even. I managed to get my setup working stable as well in Gen2 as well with my GDC Beast. Don't really know how as well, only difference for me is that I skipped doing PCI Compaction in Setup 1.3.

If you saved the setting in startup.bat and run it every startup from Setup 1.3 boot selection, prior to windows load, it should stay.

But above you said it's 2.0. Did you do the test and it's still only showing 1.1? You just have to set the pcie from setup 1.3, there's the option to set Gen1 and Gen2 in there. Sent from my D5503 using Tapatalk

By notebook drivers he means go to nvidia website and get the drivers for Gtx 960M even if you have the desktop version of the card. Problem is I don't think that will make any difference. Your problem seems very close to what I was getting with a gtx 760 and gdc beast. I never fixed the error 43 until I bought Setup 1.3 and did the dsdt override as well. What I did was in this order dsdt override, compaction in setup 1.3 for 56gb - 36bit on igpu and egpu, force 32bit on egpu or igpu (I did on egpu), downgrade pcie link speed to gen1 for egpu else nvidia driver crashes. Save all that in the startup.bat file and run it every startup before loading windows. If you can buy a PE4C cheap to replace the GDC Beast do that because from what people say it works in Gen2 stable. P.S.1 If you can disable your dgpu from bios do that and uninstall any nvidia drivers + DDU before you start trying what I wrote above. P.S.2 Also you don't want to be using nvidia audio over Gen1 so disable it in device manager.

Think you mean Pcie bus interface and you can check that with GPU-Z. Open the app and you should see something like the picture below. Press question mark (1) and start render test (2) and during test the bus interface should change to @x1 2.0. If it doesn't you need to set eGPU from Setup 1.3 to Gen2. I don't really know as well how the thing works with chainloading or startup.bat. I personaly use startup.bat option every windows startup after I saved in the file with F3 every setting I needed. P.S. So you're saying that you payed 65+22+15+25=127$ just for the PE4C adapter? Wow that's expensive. I mean I only payed about 40$ for my GDC Beast (delivered from China). I'm going to check around at hwtools but if it's at 127$ it's no deal for me. I can live with the driver crashing every once in a while and just Gen1 speed.

For 36bit I think you need to do DSDT Override before compaction but if it worked in 32bit why bother? Optimus should work right out of the box after installing the nvidia drivers. I don't know if you have to disable your dGPU from Setup 1.3 to make that work since you have an nvidia one. I had to disable my dGPU before Optimus worked since I have an AMD dGPU. You might be able to use all 3 of them and use the 630M for physics. P.S. I'm also from Romania, where did you order PE4C from? Could you reply here or in a private message with details? I'm asking because I currently have a GDC Beast but it's causing me alot of trouble (gen1 restricted else driver crashes and some random freezes from time to time).

This is getting weird. Now all of a sudden after 8 hours, computer was shut down during this time, I entered windows normally, without setup 1.3 and the video card works again. What is going on here? I mean for a whole day yesterday I couldn't get it to work for just one bootup and now it works again? Anyone any ideas? Edit: Ok update time. It's kind of working for the moment, don't know why now but I'm happy if it stays this way. Difference from above is that I didn't force 32bit compaction on the iGPU (no clue if this makes any difference or not), I had to dial down to Gen1 for the eGPU (was getting constant crashes from nvidia driver otherwise) and I also disabled from setup 1.3 my onboard LAN card (again no clue if this makes any difference but I'm not using it anyway). These is the memory range the egpu uses now: Only issue remaining is this conflict below (doesn't seem to affect system stability or something for now): P.S. Still waiting for suggestions or any insight for my setup.

Well my GDC only has one switch that seems to have 3 stages but it's been sitting to the far left since I first used it (that's supposed to be 0 delay or something). But for the love of God I tried almost every option in Setup 1.3 and it seems nothing works. Either I get into windows and the egpu has error 43 or sometimes I get a bluescreen before windows even loads up. Just tell me what info I have to provide to better help my problem solving and I'll provide it. I'm outright baffled that it worked for a week and without touching the setup or installing anything it started this error 43 nightmare. Edit: Ok so I did the DSDT override and allocate the eGPU into 36-bit, Endpoint=56.25GB, iGPU forced to 32-bit, disabled my dGPU, set Gen2 on my eGPU port but I'm still getting error 43. From the pictures below I don't know if I did the DSDT override correct. Anyone can help a bit? Edit2: Ok I actually managed to make the card show the resources tab by puting the laptop into sleep and waking it up. It's getting some conflicts here and the error code changed to 12 ... sigh. Memory Range 00000000CC000000 - 00000000CCFFFFFF not available. Memory Range 00000000C0000000 - 00000000C7FFFFFF not available. Memory Range 00000000C8000000 - 00000000C9FFFFFF not available. Input/Output Range 4000 - 407F not available.

Ok so the setup in the first post worked like a charm for about a week. After that problems have started when I was getting nvidia driver crash and error 43 shortly after restart. Uninstalling the driver and cleaning with DDU usually fixed this after a couple of tries and restarts. But now it's just stuck on error 43 and whatever I tried didn't fix it. I also got setup 1.3 but I'm a bit confused on what to do here. I managed to totally disable my AMD dgpu so now it doesn't even show up in device manager. After this I have no clue what I should do. Would love some assistance if possible else I'm afraid it will take a while with trial and error until it works.

Maybe I don't understand what you're trying to say but what's displayed there in device manager seems right to me. I mean there's the intel igpu (HD 4000) , the egpu (GTX 760) and lastly the dgpu (AMD HD7670M) that has the drivers uninstalled and it's disabled from device manager. Isn't that how it's supposed to be?

Ok so I've been running this setup very well for the past days. Only once did the nvidia driver crash and I had to restart and that happened when the laptop was idle, I wasn't even near it. Now I've tried to run the egpu using the internal monitor with no success sadly. I tried using the desktop and the laptop nvidia drivers, I tried the delay switch on the GDC Beast, I tried hooking the egpu after BIOS and before windows loads up (windows doesn't even detect the egpu if i do it this way) but no luck. I can't disable my AMD dgpu from BIOS so it's only disabled in device manager (where it's detected as standard VGA adapter). Could this last part be a problem? Do I need to edit the nvidia drivers in some way? Do I need to buy DYI e-GPU Setup to set something up in that? Hope someone can help me with this one, if it's even possible to do on my current setup.

I bought a DVI-D cable and that fixed everything. Don't know why that VGA cable was causing interference or whatever that flickering was. The issue is solved now.
