Will do! Once I get a bit of time off that is

Here is my current working eGPU setup. LAPTOP Laptop: Lenovo w530 OS: Windows 10, 64-bit CPU: Intel(R) Core(TM) i7-3740QM CPU @ 2.7GHz Storage: Samsung SSD 850 EVO 500G iGPU: Intel(R) HD Graphics 4000 dGPU: NVIDIA Quadro K1000M eGPU SETUP GPU: Gigabyte GeForce GTX 950 Overclocked 2GB 128 Bit GDDR5 PCiE Video Graphics Cards GV-N950WF2OC-2GD PSU: EVGA 500 W Adapter: Bplus PE4C V3.0 INSTALLATION 1. Convert from GPT/UEFI to MBR/BIOS using the directions on Tech Inferno Fan's setup page. 2. Install Setup 1.3 from @Tech Inferno Fan. 3. Download Nvidia driver: 361.91-desktop-win10-64bit for me. 4. Plug in PSU, PE4C(SW1 = 1, SW2 = 2), and GPU. 5. Turn off computer. 6. Plug in Expresscard. 7. Turn on computer, GPU fan comes on, PSU fan comes on. 8. Check device manager for “standard VGA graphics adapter.” Install the device driver downloaded earlier. For me the driver kept only installing for my dGPU, even when I disabled it either in BIOS or in device manager. I just kept trying different combinations and restarting the computer until it worked. There is probably a better way to do this. Once device manager says “GTX 950” then move on. Or, maybe do the next step first? 9. For me, the GTX 950 gave error 12. So, I tried a bunch of PCI-E compaction settings in Setup 1.3. It seems that the best one for me is it [ignore]dGPU, endpoint=56.25GB, compact iGPU + eGPU, force eGPU to 32 bit so that iGPU doesn’t take over. Then turn dGPU off. Add all of those steps to your startup.bat, and chainload into windows with mbr. Seems like it is automatically doing EC gen 2. Startup.bat looks like this: - call iport dGPU off - call vidwait 60 - call vidinit –d %eGPU% - call pci - :end - call chainload mbr 10. Now the eGPU will work just fine. I just chainload into windows to use the eGPU and start windows normally in order to use the dGPU. PERFORMANCE I ran 3dmark11 on using my dPGU, my eGPU with and without Optimus, and finally with my CPU set to handle PhysX. Changing PhysX to CPU was basically the same as with using the GPU, but I kept it that way anyway. Overall I am super happy with how this turned out. I can now play modded-up Skyrim with depth of field (enb) on and rise of tomb raider on high with depth of field off. I also like Homeworld (playing the remastered one now) and can play with all effects maxed out an will have fps >100, as long as vsync is off… with vsync on (default) I was getting 3fps, look out for that… Here are the 3dmark scores. 3dmark11 Score Graphics Physics Combined NVIDIA Quadro K1000M P1284 1135 7743 1015 NVIDIA GeForce GTX 950 – Optimus P6787 6797 7816 5618 NVIDIA GeForce GTX 950 – External P7291 7421 7524 6197 NVIDIA GeForce GTX 950 – External – CPU on PhysX P7369 7437 7983 6229 PREVIOUS ATTEMPTS AND NOTES The first time I tried this, I bought everything new and plugged it in and got no eGPU fan turning. I spent a long time trying to trouble shoot and finally realized that the GPU was DOA. Once I got a replacement it took less than 1 hr to figure this out. Ha. I originally thought that maybe the V8.0 EXP GDC Beast [Expresscard Version] I was using could be broken so I switched to the PE4C that I am using now. Clearly the GPU was just broken so I have an extra gdc beast... IMPROVEMENTS Would love to know if people have ideas for improvements!

Awesome! Sorry about the typo earlier, I meant to say just that... sending eGPU to 32 bit so iGPU doesn't take over. I didn't need to do a dsdt override first though.

And if you then get error 12, force the eGPU (not iGPU, oops) into 32 bit space. This is what I just got working for me with gtx 950 and lenovo w530.

Hi aldimeola81, Thanks for the response. Turns out the GPU was totally DOA as I suspected. I took it to work (haha) and stuck it a desktop--still didn't work at all. Returned the GPU, was sent a new one, it worked fine right away (well after an hour of playing with pci compaction--iGPU+eGPU with eGPU forced to 32 bit is the only thing working). I was so happy to see that error 12, such an improvement over getting not even a spin of the fan. Also, thanks to nando who helped me to realize that the card was simply DOA.

I have now also tried a PE4C, with all combinations of sw1 sw2 switch settings. So I have now tried two adaptors. I have now also converted from GPT to MBR with and installed Setup 1.3. Setup 1.3 does not detect the eGPU either. Is my brand new GPU dead on arrival? Only thing I can think of now.

Hi all, Hoping to get a bit of help with an eGPU setup. LAPTOP Laptop: Lenovo w530 OS: Windows 10, 64-bit CPU: Intel(R) Core(TM) i7-3740QM CPU @ 2.7GHz Storage: Samsung SSD 850 EVO 500G iGPU: Intel(R) HD Graphics 4000 dGPU: NVIDIA Quadro K1000M eGPU SETUP GPU: Gigabyte GeForce GTX 950 Overclocked 2GB 128 Bit GDDR5 PCiE Video Graphics Cards GV-N950WF2OC-2GD PSU: EVGA 500 W1 80+, 500W Continuous Power, 3 Year Warranty Power Supply 100-W1-0500-KR Adapter: [Expresscard Version] V8.0 EXP GDC Beast Laptop External Independent Video Card Dock Arrangement: See photo; 8 pin (GDC Beast-side) to 20 pin MB and 4 pin CPU; 6 pin PCI-E from ATX straight to GPU; ExpressCard/HDMI connector; GPU to a TV by HDMI The problem My computer never detects the card. Here is what I have tried: (1) Computer off, plug everything in. GDC delay switch is all the way to the left. Turning on the computer, the PSU fan comes on and the GDC turns on a blue light (stays on) but the GPU fans don't spin. In Device Manager, my iGPU and dGPU show up, only. EVGA 500W should be fine, as the Gigabyte website suggests that "350W (with one 6-pin external power connector)" is sufficient. (2) In UEFI BIOS I selected "Integrated Graphics" which turned off the dGPU, I turned Power>ExpressCard speed setting to "Generation 1" instead of automatic, and finally I disabled PCI LAN as a boot option (after reading gdc manual). I then used DDU to remove all of the nvidia drivers. I get the same result as before, blue light, no gpu fan, atx fan spinning softly, windows boots up normal. Only the iGPU in Device manager. (3) Finally, I did the PSU paperclip trick, to force the PSU to be on during boot up. Light is blue, no gpu fan, and then turn I on the computer and nothing new happens. Simply doesn't show in Device Manager. I had to disconnect the 20 pin connector in order to place the paperclip, but figured this was fine since the only wire coming from it to the gdc is the ground for signaling on/off. (4) I have also do most of these options with the delay switch in the middle (7s) and right position. I have also tried plugging in the ExpressCard at odd times, like during the windows startup or while the laptop is already on. I have not tried setup 1.3 because I am not sure what problem I have here and how this would help. Would whitelisting cause this? Everything is super new so probably there aren't any hardware issue here i suspect. I picked this adapter over the Bplus one because the banggood website lists my computer as compatible. Please chime in if you have ideas. Thanks in advance (is this the place to post this question, even though it is about expresscard type adaptors?). Best, Dan
