Hi, I would like to share my eGPU experience with EXP GDC V8 ExpressCard on my W520, Quad core i7, 12GB RAM, Quadro 2000M 2GB dedicated VRAM, Windows 10 Pro 64bit.
last month after weeks of fails and errors, (specially the famous Error 43), i finally got my EXP GDC running using mPCIE version with NVIDIA Quadro 4000 for Mac (yes, for Mac!)
I make it works by setting the PTD switch to 7s. But by the time Windows successfully detect my Q4000 i straught away hook up my external monitor (EIZO CG245W 24-inch) to my eGPU, then the system blinks, i assume it detect a display signal. but it wasnt. And my W520 suddenly shutdown. And i can not make it work again. Even after hundreds of time reinstall-uninstall NVIDIA Drivers with DDU it wont make it work again.
So, at this point i switch the GPU to my Quadro 6000 6GB GDDR5, and repeat the last success process. Nothing happened. Our good friend Error 43 back again and stay there forever.
In my desperate time, i finally ordered the ExpressCard signal Cable.
While waiting it's enroute somewhere in China, I test the EXP GDC with my AJA Kona 3G 4K I/O Video Capture Card, and hey it's working! i can do Edit & Realtime Preview 4K RAW video files thru the card flawlessly, It utilized the card's hardware encoding, (4K RAW files from ARRI & RED Camera) as well as output 16-Channels 192KHz Audio signal from my DAW. (no additional 6-pin power required for this card)
Then i test my both Quadro 4000 & Quadro 6000 GPU back to my HP Z800 workstation, guess what? They're both bricked! It received power, but system cannot boot up. Beeping. means GPU is faulty.
The next day, my AJA Kona 3G card also bricked!
Today the ExpressCard signal cable finally arrived along with my 6-pin + 6+2 pin, but again, when i use the ExpressCard setup it doesnt do anything. No power comes in to the EXP GDC. My 500W ATX PSU is running though, but the LED indicator on the EXP GDC not lit. i set the slot to Generation 1 power mode in BIOS.
So, I've tried both mPCIe and ExpressCard on W520 with nothing but frustrations. Did i miss anything here?
I appreciate any workaround on this. Since i've never found any eGPU setup with W520 anywhere in the net. specially using ExpressCard & a High end Quadro GPU.
Here's my last config that i've managed to make Q4000 work:
Whitelist latest BIOS 1.42 Power Management: Both for Processor and PCI set to Disabled Display Mode: Integrated Graphic OS Detection Mode for Optimus Graphic: Disabled PXE Boot and all Network Boot options including PCI LAN Boot order : Disabled Win 10:
Device Manager: System Detect eGPU, Error 43 Uninstall NVIDIA Driver with DDU (safe mode) Reboot Check BIOS first, usually it will set back the Display to Optimus Mode, i Let it Boot in OPTIMUS MODE Make sure Graphic Card(s) is detected in Device Manager as a 'Basic Microsoft Display Adapter' Install Quadro driver for both Discreet Graphic & eGPU Reboot to BIOS Display Mode: Integrated Graphic OS Detection Mode for Optimus Graphic: Disabled Quadro 4000 for Mac successfully detected in Device Manager. Plug my external monitor to eGPU GPU Bricked
Same as mPCIe method ExpressCard Power mode: Generation 1 Nothing happened

You will know your graphic card is working fine when you power on your laptop, normally all Quadro cards fan spin at normal speed, then it will spin faster/accelerate for 3-4 sec at Windows logo, means the system & OS detects your card then it back to normal fan speed. During the setup, i often get my Quadro 4000 fan spin so freakin fast. Faster then the POST boot init, but then back to normal speed Bricked Quadro Graphic Card: Quadro 4000 Fan spin fast forever, while Quadro 6000 stays low speed.
Thanks a lot!
15" Dell XPS 9550 + GTX970@16Gbps-TB2 (AKiTiO Thunder2 via Kanex TB3 to TB2 adapter) + Win10 [jowos]By jowos
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.
system recognizes gpu driver installed no problem on external screen [Partially] Optimus working, just don't disable the GTX960M in Device Manager. Only works for Furmark.
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
Download the newest NVIDIA driver. update the TB3 firmware and TB3 management software on Dell.com, or as instructed on https://thunderbolttechnology.net/updates per manufacturer. 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. Plug the setup in, and power on. Windows should boot just fine. Use display driver uninstaller to remove the old drivers. http://www.guru3d.com/files-details/display-driver-uninstaller-download.html Install the newest driver downloaded in step 1 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. :-(
Geforce experience recognizes GTX970 no problem NVIDIA Control Panel recognizes all three with no problem. 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' 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. 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:
modifying the nvidia driver per this video, with no avail. [in progress] just purchased this headless hdmi plug to simulate a dummy display, and use Win+P with screen share option. [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. 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? 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
I have a setup almost identical to this build:
1. AKiTiO Thunder2 PCIe Box
2. EVGA GeForce GTX 750Ti with G-SYNC Support 2GB GDDR5 128bit, Dual-Link
3. GameMax GM450 OEM (GM-450) - 450W power supply
4. Macbook Pro Retina 13 (2013)
I installed the latest drivers from the EVGA website. I connected external display via HDMI and can see my card in Device Manager.
The problem is under a smallest load (starting a game or Unigine Heaven test), the whole system freezes, picture from the external display disappears, although fan on graphic card is still going.
Any ideas how this can be fixed? I took power from the Molex connector. Could that be the problem?
I'm using a 2015 MBPr 15" (running windows 10 through bootcamp), with a gtx 1070 plugged into an akitio thunder 2, which plugs in to the thunderbolt port on my laptop.
I tried to install the drivers, but the installation software cant recognize the gpu plugged into the thunderbolt port. It also doesn't show in device manager. Interestingly enough, several new things appear in device manager, under system devices, several PCI upstream and PCI downstream switch ports are connected, which seem to be from the thunder2. The lights on the GPU itself change depending on whether or not it is plugged into the thunderbolt port, and I'm certain that it's getting enough power from my PSU.
Can anyone help me get this set up?
