It always says "There are no applications running on this GPU", no matter what I throw at it.

 

I wouldn't trust the system tray widget. Can you run an app (e.g. Furmark) or game and see which card the app is using, as reported by the app itself?

Ran Furmark, here it is while it ran:

Here's the output:

furmark-score.jpg

 

I also ran LA Noire at 1080p max settings and got like 10fps.  

 

This is what the gpu activity monitor always looks like:

That is the oddest thing. It does look like the apps are running on the wrong card, but what's weird to me is Furmark's benchmark report...

 

It says the renderer is the Intel GPU, but has the PCI ID of the GTX 970 (10DE is NVIDIA's Vendor Code...)

 

I'm really stumped at this point. Does the 970 work when you have a monitor hooked up to it, and boot into Windows "normally" (i.e. non-Optimus mode)?

That is pretty weird.  Yeah, I've played a few games already with the external monitor hooked up to the 970.  Can run most things 1080p at max (or almost max), certainly miles better than the 750m.  

 

What nVidia drivers are you using?  Latest (368.81)?

Here's what it looks like on my end. Maybe try creating a program-specific NVIDIA settings page for furmark and setting it to use High-Performance, see if that changes anything?

Tried that too.  Nothing.  I mean I would've given up a long time ago if it wasn't for the fact that we're running basically the same setup.  Same computer, OS, drivers, akitio thunder 2, we ruled out that it was the card.  I'm really out of ideas.  Super lame.

 

Here's an overview of the setup with more details (note: I rolled back drivers to 368.39, just to check, since someone had done it successfully with those)

Edit:

Evidence that GTX 970 works with external monitor.  I had to disable the 750m for furmark to use the 970, this was before setting up optimus.

Just to check the obvious, the 750m is disabled while you're trying to run Optimus, correct?

Yeah, I boot normally, disable the 750m, set igpu with gpu-switch, restart with egpu plugged in.  I can see all three on device manager, and 750m is disabled.  When I mouse over the optimus icon in the toolbar it says:

 

GeForce GTX 970 (Inactive)

GeForce GT 750M (Disabled)

...weird, it shouldn't say inactive.

 

Does the 970 show up in Device Manager okay? No exclamation marks or "device could not start" messages?

 

You're booting up with apple_set_os before you boot into Windows, correct?

Everything looks good.

And yeah, I'm using apple_set_os with rEFInd before booting windows.  Otherwise the Iris Pro doesn't run.

Damn. I'm stumped. I know that the 970 for sure works with Optimus as one of the guides I used for enabling Optimus was running a 970.

Wish I could help figure out your problem but I'm at wit's end over here. Sorry man.

Aw well, I'll look into it more when I have time.  Guess I'm out of luck for now.  I'll post if I find anything.  Thanks for all the help though.

Added this to original topic:

 

(NEW) FIX FOR macOS NOT POSTing: Run Goalque's script in "-a mode". This apparently alters something regarding the thunderbolt chipset on every shutdown, so when rebooting back into macOS, the eGPU will initialize properly every time.

My setup: late 2013 MBP 15" + 750M + Palit GTX 980 Ti Super Jetstream eGPU + Akitio2 + Enermax ELT500AWT PSU.. 

Under OS X 11.6 with security update: GTX 980 Ti were recognized as "NViadia Chip Model" only. So done a clean install with El Capitan (15G31) and wiped out the SSD, installed OS X and Windows 8.1 (EFI-Mode). I tried to use the eGPU-Setup-1.30 to activate the iGPU, but no luck to run successfully the PCI-Compaction. After all I'm only using the automate-eGPU with "-a" switch, otherwise it will be impossible to see the boot manager and boot into OS X or Windows 8.1 (EFI-mode). Only at the first boot after Windows Installation could GTX 980 Ti be recognized by windows. Installed the newest NVIDIA driver and in Device Manager appeared 750M and 980 Ti, both working correctly.

Here the trick to boot into Windows with always working GTX 980 Ti (and maybe other)  - automate-eGPU-Script with "-a" switch already installed:

  1. Boot into OS X - TB unplugged 
  2. Plug TB in and restart OS X - from now on TB is plugged in
  3. Boot into OSX again  and restart OS X
  4. Boot into Windows - Check Device Manager - only 750M will appear
  5. Restart Windows - Check Device Manager - 750M AND 980 Ti are enabled 

For Optimus in this constellation it is not necessary to have an Optimus-GPU like GTX 970. All you need to have is a dummy HDMI-to-VGA-Adaptor and tolls like "Dual Monitor", setting the dummy Display as primary. 

 

OS X recognizes the 980 Ti with the Dummy Adaptor:

Look at NVIDIA Driver Manager:

 

Bildschirmfoto 2016-12-31 um 17.01.36.jpg

 

It works fine so far, BUT every time i try to start an Benchmark Tool like Cinebench, the PSU stops working after 6 seconds of running. During this 6 seconds the PSU makes noises that sounds like "buzzing". After reboot I got this:

Same on Windows: whenever 980 Ti is under load (game or benchmark) I have a black screen with white mouse on display, sometimes freezes. Can anyone explain what's going on?

 

EDIT: Probably found the cause of the freezes and it might be my insufficient psu that is unable to provide enough power for the 980 Ti. I thought 500W will be fine, but taking a look into manual shows me I was wrong. 250W is reserved for the CPU and another 250W for the rest on two +12V rails.  Conclusion: a new psu is already ordered and on the way.

@irokez dude lol you're posting a general tech support question directly into my build thread FYI haha. 

 

Might wanna post it somewhere where it'll get more hits, like a new topic in the eGPU experiences forum. 

 

FWIW I think it's your PSU as well.

Yes, it was... Thanks for your advice!

Now all works ok! I'm working on a solution to work with my 980 Ti on Windows and OS X with high refresh rate through HDMI dummy adapter and HiDPI resolution. 980 Ti is not Optimus compatible, so it's working with the dummy adapter only that simulates a second display.

Awesome setup. Gives me hope that you have a 750m and got optimus to work!

 

What is your osx setup? clamshell mode? When you are running FCPX are you just using your external display?

 

I thought I was getting a bump in Resolve, but after hours of rendering I noticed I was not getting a gain over the 750m. From my research Davinci has a problem choosing a cuda enabled device and always defaults to the internal.

 

thanks in advance!

@Jmlee5 - in macOS I use it with the laptop open, and use https://github.com/Eun/DisableMonitor to blank the laptop LCD and prevent my cursor from going to it. I have a 4K IPS panel at work that I hook directly to the 980 via DisplayPort, and that is my primary monitor.

 

I never tried clamshell, though I used to have the laptop open slightly (around 10-15 degrees) underneath my monitor stand...but after I had to take it into AppleCare for a display failure, and noticing how hot the surface of the display was getting...those two facts may not be related but it scared me enough to always try to keep the laptop open at least 90º when using it with the eGPU. 

 

I have no acceleration issues on FCPX or 3D apps (Elite Dangerous on macOS uses the 980), but it's probably because I'm using an external monitor.

Amazing!!! I can't wait to try it out with davinci. This might solve a lot of problems people are having. I'll update later. Laptop is out on a job right now.

You are the best! There is a whole thread about this problem. 

 

I get 14fps with my gtx980ti with 3 color correction nodes and daisy chained my ultra studio mini monitor for output with 

alexa uhd 444 footage. You are going to make a lot of people happy. Footage can not be on the same thunderbolt bus.

 

optimus next.... Have you successfully overclocked the Retina display to fire at higher hz?

Nah, I rarely use Optimus (am on a 4K 60Hz at work and a 1080p 120Hz monitor at home for gaming) so I haven't tried to overclock the internal display at all.

      We've had a stack of recurring questions from with problems getting a mPCIe eGPU working. This includes GPU-Z not reporting no clock details, error 10/43 or even not being detected at all. Overall it's more troublesome getting mPCIe working than say expresscard or Thunderbolt.
       
      Here's some common problems and some troubleshooting steps to correct them.
       
      Getting a black bootup screen, resolving error 10/43 or ACPI_BIOS_ERROR win bootup messages
       
      Here the BIOS doesn't know what to do when it sees an eGPU. So the solution is to not let the BIOS see it. Do that by setting the delays on the eGPU adapter (CTD/PTD - EXP GDC or CLKRUN/PERST# on PE4L/PE4C). Boot with eGPU adapter in the wifi slot into Setup 1.30 or Windows. Is the eGPU detected?
       
      I'll add that should error 43 continue AND you have a NVidia dGPU as well as NVidia eGPU then it's likely because of having the mobile NVidia and desktop NVidia drivers loaded simultaneously. Proceed to uninstall ALL your NVidia drivers, use "DDU" to clean NVidia registry entries and do a 'clean' install of the latest NVidia desktop driver.
       
      mPCIe port that hosted the wifi card disappears when connecting an eGPU in it's place
       
      Use the Setup1.30 PCIe Ports->enable to enable the missing port.
       
      eGPU does not get detected
       
      Overcome mPCIe whitelisting by booting with the wifi card and then hotswapping in the eGPU. That way the BIOS will enable the mPCIe port to work.
       
      1. Boot with wifi card into Windows, sleep system, swap wifi card for mPCIe eGPU adapter and ensure eGPU is powered on, resume system. Do a device manager scan in Windows. Is the eGPU detected?
       
      2. Boot with wifi card into Setup 1.30 *carefully* hotplug the eGPU adapter in place of wifi card. Hit F5 to rescan the PCIe bus. Is the eGPU detected?
       
      If this enables detection then avoid this tedious hotswapping by seeking a unwhitelisted modified BIOS for your system OR test the Setup 1.30's PCI ports->undo_whitesting feature.
       
      eGPU still not detected - set the PSU to be permanently on
       
      The latest EXP GDC and BPlus eGPU adapters try to manage the PSU to only power on after they detect a signal. This can cause a race condition where the eGPU isn't ready to go when the CLKRUN signal is asserted.
       
      Avoid this by jumpering the PSU so it's permanently on rather than being managed. Depending on the PSU you are using refer to the following doco on how to do that:

      http://forum.techinferno.com/enclosures-adapters/9426-220w-dell-da-2-ac-adapter-discussion.html
       
      eGPU still not detected - a non-standard mPCIe implementation by your vendor?
       
      PERST# mPCIe pin 22 may need to be isolated due to a non-standard implementation by your notebook vendor: http://forum.techinferno.com/enclosures-adapters/10812-pe4x-series-understanding-clkreq-perst-delay.html#post142689
       
      eGPU still not detected - faulty hardware?
       
      If you still don't get detection then test the video card and eGPU adapter in another machine to confirm neither is faulty.
       
      NVidia driver stops responding
       
      EXP GDC, PE4H 2.4 and PE4L 1.5 all use a socketted cable and therefore are not true Gen2 compatible device. This error indicates there was transmissions errors.
       
      The solution is either to get a better Gen2-compliant eGPU adapter such as PE4C V3.0 or PE4L 2.1b (both with soldered cable), or downgrade your link from Gen2 to Gen1 using BIOS options or Setup 1.30

      Required items:
      1.) Lenovo u310 (I have a Core i3 - Ivy Bridge, 8GB RAM)
      2.) 65CN99WW unwhitelisted.
      3.) eGPU (I used a EVGA GTX 750 Ti from another computer I had).
      4.) EXP GDC mPCIe Edition adapter (got from eBay - banggood seller).
      5.) ATX power supply (I used a 600W PSU from another computer I had).
      6.) USB wireless.
      7.) External monitor, keyboard, and mouse.
       
      Steps:
      1.) Obtain and install a unwhitelisted BIOS. If you are unable to obtain a unwhitelist BIOS, I think it might be possible to bypass it with Tech Inferno Fan's Setup 1.x (may need confirmation as I haven't used it myself yet.)
      2.) Shutdown computer and remove all USB devices, ethernet cables, power cables, card reader cards.
      3.) Remove mPCIe wireless card and detach antennas.
       
       
      4.) Attach EXP GDC external mPCIe cable to the former wireless slot and screw down.
       
       
      5.) Attach HDMI end of the mPCIe cable adapter to the EXP GDC device.
       
       
      6.) Attach graphics card to the EXP GDC device (I moved my laptop off the desk and onto the side shelf to make room on the desk for the monitor/keyboard/mouse).
       
       
      7.) Using the power cable adapters that came with the EXP GDC device, I hooked in my ATX power supply's 20 pin and CPU 4 pin cables. Then hooked the other end (8 pin) into the EXP GDC device. My EVGA 750 Ti also required that I use an additional PCIe power cable (6 pin) in the top of the card.
       
       
       
       
       
      8.) Then I attached my misc devices (HDMI monitor, USB keyboard/mouse/wireless adapter), and hooked in my PSU and powered it on (below is image of final product, also moved HDMI cable out of the way).
       

       
      9.) Power on your computer and let it install the standard VGA drivers and then install your drivers (I didn't have to go in the BIOS for any graphics settings, which it doesn't have anyways, nor did I have to disable iGPU in Device Manager before the card was added).
       
      Extra Info:
      I found that most games will play on med settings with about 45 FPS with this particular card.
      BDO: Upscale on - Anti Aliasing on - SSAO off - med settings.
      Skyrim: Med-High settings.
      Fallout 4: Med settings.

      Hello, A couple of days ago I got a new GPU but when I installed it into my computer I was unable to use it but now I know why. When checking the device manger I went into the events tab of my GPU when I went to view all events, I noticed an error it said " event 411 kernel PnP " and It also said Problem Status: 0xC01E0438. I believe this is why my GPU hasn't been working on my PC. If you know how to fix this problem or have info on how to fix this problem that would be greatly appreciated. I'm also using a EVGA NVIDIA GeForce GTX 1660.

      I'm having a problem where my PC is saying my eGPU is not usable, its detected in the Device Manager and it doesn't have the yellow triangle next to it. I cant use it games and the Nvidia Control Panel doesn't recognize it either. I'm using a EVGA NVIDIA Geforce GTX 1660. I'm using windows 10 and I tried DDU and reinstalling them and now I cant access the nvidia control panel. The GPU is not recognize on any other apps and I went on *********** and was unable to find my answer, Any help on how to fix this problem would be greatly appreciated.
