@jowos Just an FYI, I've managed to get my Thunder2 working on my XPS 9350 using the StarTech TB3TB adapter. I have had some issues here and there, mostly screen flickering issues and one BSOD, but Optimus seems to be working nicely. I played Crysis 3 on High settings at 1/2 native (3200x1800 = 1600x900) on the internal screen without issues. I have a 9550 that I can use for testing, so I'll see if it has to do with the 960M.

external screen should do the trick. You can find out I went through the same hassle in my XPS 15 implementation guide.

@jowos I play Doom on windows, my wife plays The sims 3 on windows. On Linux, I was playing OpenArena, Quake 3 and Xonotic. But I'm so into Doom right now, I stopped playing anything else.

So while you played Doom, were you using an external monitor plugged on eGPU? Or on the internal monitor? I would be very curious to know your configuration if it's the latter.

Nice one! Are you playing those titles in linux?

Glad to see the startech.com adapter working! I used Kanex one in my setup. From the look of it you are connecting the monitor on your eGPU, which hides away the problem with Optimus. Also you mentioned the TB3 Prototype? Is there a link to it?

Thanks for your reply! I actually did get my setup working successfully with an external monitor, and Physx should be working (didn't test) too. The thing is I've been trying to get it working without an external screen, and with internal display through optimus instead. Ideally, rendering should be done on eGPU and piped back to iGPU to get displayed. The same setup (w/o the Kanex adapter) worked for my MBPr 13, with Optimus support out of the box, so that I could play big titles on the internal display without any external screen attached to eGPU. I still don't have a clue why it's not the case with my XPS 15.

@jowos Yeah it's an old Fermi card please don't compare it with recent GTX cards 

 

My setup was pretty much off an old hardwares, i'm trying to make a good use of a 4 yo GPU, Laptop and Monitor as it was back in it's glorious days. lol

At first i use mPCIE but it was very unstable, i believe it cause both of my Quadro cards bricked. Now i'm running on ExpressCard. And yes, it's on x1 v1.1.

I still can play Fallout 4 with Ultra settings on 1920x1200@60Hz, but i tend to use it more for 3D & VFX stuff

 

 

I used to have an exp gdc solution with my X230T too, and it was with a GTX670. Back then you needed some magic to get Internal Display to work.

So I tried fluidmark w/o external monitor, and the entry screen says "Physx - CPU only". And I cannot install the standalone Physx driver because it complains an identical or newer driver already exists.

@jowos Just found out that we need to install PhysX System Software in order to make PhysX work properly and detected by GPU-z.

I did some test,  by installing latest PhysX System Software it greatly improves PhysX benchmark on FluidMark. But computer freezed twice during Fallout 4 loading and FluidMark fullscreen benchmark. 

I need to install Legacy PhysX software as well to make it run smooth (for old Games or Games that use old PhysX SDK). But i didn't use it much for gaming though. Only for 3D & VisualFX Applications.

 

 

If you think it's working fine. no need to install it though.  It's just work as it is.

PhysX System Software: http://www.nvidia.com/object/physx-9.15.0428-driver.html

 

Nice post btw!

Thanks for your reply! GF100 reminds me of my GTX480 lol. BTW, can you tell me your setup, i.e. model of your laptop, and are you using optimus? I can see x1 1.1 so I guess it's a mPCI-E solution? I haven't tried out FluidMarks yet. I'll give it a shot. I assume it would work even without hooking an external monitor onto it.

Can anyone confirm that on GPUZ, normally GTX cards' CUDA, PhysX was not checked? Since i saw others GPU-Z screenshots that enabled CUDA & PhysX, but it was from Desktop PC.

My screenshot was not checked. :/ Didn't test it either. Strange thing, though. My guess is some mis-recognition, as the dGPU is also unchecked, while working fine.

Did you do anything like Tech Inferno Fan's diy gpu setup 1.30?

awesome dude

 

beside Razer,

Gigabyte and Powercolor has TB3 enclosure

But it don't released yet

Thanks dude . I feel NVIDIA is officially working on a hot-pluggable solution, and all those non-propriety enclosures will be released once the driver is ready, because even with my set up I'm already able to hot-plug in/out my GTX970 without crashing the system, and in the GPU activity monitor there's even a 'disconnect' button. I hope the Optimus support is somewhere on their schedule.

Lol, Easy fix.

I was really curious to see if those adapters would work properly.

Nice work in there!

They do as long as Optimus is not concerned.

This is probably the first trial online involving a TB3 to TB adapter.

Update on Noon July 23rd 2016: works seamlessly with an external monitor. However, whenever I select Duplicate in projection mode, the rendering will be carried out on iGPU/dGPU(if you do not disable it)

Update on Morning July 23rd 2016: Turns out the Optimus is only working for Furmark. i.e. No game would run on GTX970. Nor would 3DMark. It seems an external monitor is still a necessary fix.

What's working:

1. system recognizes gpu
2. driver installed no problem
3. on external screen
4. [Partially] Optimus working, just don't disable the GTX960M in Device Manager. Only works for Furmark.

Background

In the spring, I came to the States for one-semester exchange. I obviously couldn't get myself a full-size gaming rig, so I chose to build an eGPU with my MBPr13 2015. I got my AkiTio Thunder 2 and GTX970 then, for about $500.

Later in the summer, I purchased a XPS15 (discussed by the low-voltage cpu in my MBPr 13), was enthralled by its borderless display. It came with a TB3 port, but the only option out there for TB3 is Razer Core, another $500 investment. In the mean time, A few TB3 to TB adapters rolled out, currently only Kanex and StarTech.com models available, for around $80-100. I asked a bunch of questions regarding AkiTio Thunder 2 + TB3-TB adapter + eGPU on Amazon but no luck. So I decided to get one myself and try it out.

About the adapter

I got it on amazon for $100.  https://www.amazon.com/gp/product/B01EJ4XL08/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1. In fact the StarTech.com one is 20 bucks cheaper, and I believe they should harness similar technology under the hood, but I would trust Kanex for I have already owned their USB3.0 hub and it worked pretty well.

The hardware setup

(Picture coming soon, when I get back dorm)

The software setup

1. Download the newest NVIDIA driver.
2. update the TB3 firmware and TB3 management software on Dell.com, or as instructed on https://thunderbolttechnology.net/updates per manufacturer.
3. In the UEFI settings, turn on all the checkboxes in Thunderbolt tab, and make sure the thunderbolt security settings is set to lowest (Cuz Akitio Thunder 2 is not verified for TB3). Or you can manually consent in windows, if the security level is normal.
4. Plug the setup in, and power on.
5. Windows should boot just fine.
6. Use display driver uninstaller to remove the old drivers. http://www.guru3d.com/files-details/display-driver-uninstaller-download.html
7. Install the newest driver downloaded in step 1
8. reboot, and you should be able to see all three graphics card in Device Manager. (Intel 530, GTX960M, GTX970). You are free to disable GTX960M, but that doesn't help anything so far. :-(

Result summary

1. Geforce experience recognizes GTX970 no problem
2. NVIDIA Control Panel recognizes all three with no problem.
3. Under internal display, no game would run with GTX970, even after disabling GTX960M. GTX970 shows up properly in the GPU indicator, but it's always 'inactive'
4. It works! Just don't disable GTX960M, and tasks will be automatically assigned to GTX970 when needed. Only works for Furmark. No games and 3D Mark would work.
5. External monitor works flawlessly. Can't get 'duplicate' projection mode to work though.

Trying to fix the internal display (Optimus) problem

As my MP-CL1 micro projector seems to defect, I've no access to external display yet to test the card out. And I'm not yet able to get the eGPU running on internal display either.

What I have tried:

1. modifying the nvidia driver per this video, with no avail.
2. [in progress] just purchased this headless hdmi plug to simulate a dummy display, and use Win+P with screen share option.
3. [just contemplating] maybe should get Razer driver to work? But Razer Synapse should only recognize Razer Core, so need a side-door. They say the driver is open-source, but I cannot find it on Github anyway.
4. Just don't disable GTX960M and it partially works (only for furmark). Maybe furmark is rendering the content internally and pipe the image out through a different gpu manually?
5. Windows 8.1 not working. I just installed a copy on my SanDisk SSD 500 external SSD. GTX970 cannot co-exist with GTX960M, and disabling GTX960M still doesn't enable rendering on GTX970.

With external display

Will update once I get my MP-CL1 working (hopefully it's just a drained battery), or when I get back to Hong Kong.

Just remembered there's a common area in my dorm with a TV. Got to try it out some time.

Tried out on the TV, able to achieve ~20000 on Sky Diver. With GTX960M it's around half

Mine is on the way. Are you using the internal LCD with eGPU? If so, did you use the efi patch?
