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: mPCIe method: BIOS: 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 ExpressCard Method: Same as mPCIe method ExpressCard Power mode: Generation 1 Nothing happened eGPU setup: EXP GDC Beast V8 500W ATX PSU DELL 220W Power Adapter (backup for small cards) PCIe 6pin+6pin+2 auxiliary power cable (backup spare) ExpressCard Signal Cable mPCIe Signal Cable [IMPORTANT NOTE]: 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!

Hi! I've currently got my Akitio Thunder 2 + MBPr setup working beautifully with Windows 10 - except for one annoying issue. Sometimes when I boot up Windows 10, the OS will try to output on the output of my eGPU (GTX 960) instead of the internal display. This means that I can't log into the OS and that I have to force-reboot. Sometimes I time the bootup correctly, and everything works perfectly, but sometimes it doesn't - which is very annoying. Do any of you guys know a way to force Windows 10 to use the internal display - always - even if an eGPU is plugged in (basically forced Optimus)?

One month ago, i've started my first eGPU project. I was looking for a solution to improve my render times. I've searched the web for possible solutions and i found this site. After two days reading a lot of articles in this forum, i've made my decision. So i started a new thread "eGPU with IMac 21" 4k (late 2015)" in the section "Apple eGPU discussion" and wrote down my questions. Within a few hours, I've got all the answers i needed (many thanks to @Dschijn! Without his recommendations, gain experiences and hints, i never would be able to build my egpu). When i finished my first part of my egpu project, Tech Inferno Fan asked me to post an implementation guide. So here is my implementation guide: Because i want to speed up my render times, i needed an GPU with a lot of CUDA cores. So i decided to built up my eGPU with a high performance GTX 980 TI. My Hardware: iMac (Retina 4K, 21.5", Late 2015) 3.3 GHz Intel Core i7 1TB Fusion Frive HDD 16GB 1867 MHz DDR3 RAM The components, I bought: Akitio Thunderbolt2 PCIe Expansion Box MP-TB-PCIE ( https://www.format.de/Products/5961/index.php?gclid=CPDWsYn2hsUCFUblwgodMa0AVA) ASUS STRIX GTX 980 Ti (http://www.hiq24.de/shop//GeForce-STRIX-GTX980TI-DC3-6GD5-GAMING,-Grafikkarte/170245/100/i.html?) PSU: Thermaltake Smart SE 630W (http://www.hiq24.de/shop/Hardware/Komponenten/Netzteile/ab-500-Watt/Smart-SE-630W,-PC-Netzteil/81758/9512/i.html?) 24-Pin ATX adapter (https://www.caseking.de/bitspower-24-pin-atx-ueberbrueckungsstecker-zuad-083.html) DC cable (http://www.reichelt.de/DC-AKS-7525/3/index.html?&ACTION=3&LA=446&ARTICLE=150126&artnr=DC+AKS+7525&SEARCH=niedervoltstecker+2.5mm) MOLEX adapter (http://www.reichelt.de/DELOCK-82315/3/index.html?&ACTION=3&LA=446&ARTICLE=143815&artnr=DELOCK+82315&SEARCH=6-pin+pcie+kabel) Within a few days, i have got everything, i need. I've opened the AKiTiO. I bend the back part of the case a bit because the GTX980TI is to long. I put the GPU into the PCIe slot I connected the two 6+2 power cables from the PSU to the GPU With the DC cable and the MOLEX adapter, i've built up a power connector for the AKiTiO (as described here in the forum) I prepared the ATX adapter for the paper clip trick After this steps, i connected everything together and so i've got my eGPU in the "ghetto-mod" version I connected the TB2 cable (included within the AKiTiO) and switched on power at the PSU Then i've turned on my iMac (now the blue LED at the AKiTiO lights) For the driver installation, i've downloaded the script: https://www.techinferno.com/index.php?/forums/topic/7989-script-automating-the-installation-of-egpu-on-os-x-inc-display-output/ I've followed the instructions in the thread. This script is doing the installation automatically (thanks to goalque for this amazing work) After the first try, I've got the message "nvram: Error getting variable - 'csr-active-config': (iokit/common) data was not found" To solve this, the SIP has to be switched off (csrutil disable) when using MAC OS X El Capitan (here is a link http://www.macworld.com/article/2986118/security/how-to-modify-system-integrity-protection-in-el-capitan.html) Then i boot up my system and installed the latest CUDA driver package from NVIDEA I started my 3D program and the external GPU was recognized directly. I did a few test render,, the performance was great :-) Then i connected an external monitor to the eGPU via a HDMI cable and after i made the external monitor to my primary monitor (https://support.apple.com/en-us/HT202351) everything works fine. Conclusion: The whole project has lasted one week. The system runs very stable and the fans are very quiet. Many thanks to this forum! The next steps will be: finding a suitable case for my PSU, AKiTiO and GTX upgrading to OS X 10.11.3 and the latest NVIDEA driver installing Windows 10 (via BootCamp) and make the eGPU running under Windows Update: I have just updated to MAC OS X 10.11.3 and NVIDEA Web Driver 346.03.05f01 (incl. CUDA Driver Version: 7.5.25). Everything works fine. Update: A few days ago, I also installed Windows 10 /with Bootcamp). I followed the instructions (and the power up sequence) by ZapCord and everything works fine. The eGPU will be recognized and i am able to do fast renders. On the external display, the eGPU works brilliant, only OPTIMUS will not work.

Hello everyone, I just installed a new 880M into my M17x r4, booted into Debian and everything worked perfectly (using proprietary drivers from previous 675M) But things didn't look so nice when I logged into my Win7. I downloaded the latest drivers from Nvidia(361.43), created a modded inf and the installation failed The error looks like the screenshot on this page: http://www.custompcguide.net/2-methods-to-fix-nvidia-installer-failed-issue-for-geforce-video-cards/ I have tried: DDU, Safe Mode, Disabled Driver Signing Mode, "Manual" Install through device manager, two other versions of the driver and more(tm) So after trying all possible guides that I could find online, I decided to install another copy of win7 onto a clean partition. The driver install worked flawlessly and I managed to even get a stable +60/+200 overclock on the card, yay Migrating my previous windows installation by reinstalling all programs would at least take me another two full days and cost a lot of nerves :/ Thus I'm asking you guys whether you know a way to either - get the drivers to install - copy the drivers from one windows installation to the other (both are win7 ultimate x64) - easily get the old programs moved over to the new partition (including registry, user accounts and all other windows stuff) my old windows installation has experienced dd(cloning hdd) and multiple partition resizes besides being windows and thus slowly decaying over time. looking forward to your answers bonus questions: my 1440p screen flickers sometimes. might this be caused by the integrated graphics and could i disable it somehow? (i have tried different dp cables) what OCs have you achieved on the 880M? what's the maximum voltage that you'd classify as safe? temps with current OC dont go over 70C, stock cooler is pretty loud though

Hello I recently re-installed Windows 10 after an SSD fail, which meant that I had to redo my DSDT Override. I was wondering if there was any other way of fixing error 12 than those suggested on the forum (that I know of), when I found this tool called BAR-Edit 3.2. The BAR is supposedly the PCIe memory space (unless I totally have this wrong), and I was thinking if it was possible to use this software to edit my eGPU's resources so it would work. Anyone know if this is possible? -Aerostar P.s. I didn't know where to post this, so I created a new topic (sorry if this is annoying)

Hello techinferno-team, I decided to finally register on the site and in this forums as I have read a lot about eGPU implementations and actually tried to accomplish one by my self. Those are my parts: Lenovo Thinkpad t430 with i5 3320M, 8GB DC RAM, 160GB SSD, Intel HD4000 EXP GDC BEAST, Expresscard bequiet! 450 Watt PSU Windows 10 64bit. So far, so good - but it just won't work. Everytime I boot my Laptop up with eGPU connected, it loads the Windows 10 screen with the blue logo on it. After app. 2 minutes a little circle spins around, suggesting the PC is loading the OS. I waited to hours, the screen remained the same. Then I tried booting Windows up, then instering the eGPU. That does not work either, as the card is not recognized. I tried putting laptop to sleep, plugging eGPU in, then waking it from sleep. It just turns off. I also tried powering the PSU of the eGPU on when the windows logo appears, but the card is not recognized and the fan of the GTX670 spins like crazy. First time this appeared I almost thought I bricked the card. Then I tried another thing: I used the egpu with my old Thinkpad t500 on windows 7. I plugged it in, booted up, installed drivers, done. It works. So the eGPU components should work fine., I I am absolutely at loss here. What can I do to get this thing working? I have read like every article about eGPUs on T430 and on Windows10... But it just won't work. I would very much appreciate your help in this case; furthermore I hope this is the right place to post this in. If not, I apologize - this is my first post. I am not a native speaker, so if you do not understand something in my text feel free to ask, I will do my best. Thank you so much! daku I tried every setting advised in the existing troubleshooting guides at least twice, none of them worked.

Hello Guys. I have the Lenovo Y500 with Windows 8. I just want to ask if you rate me to download windows 8.1 or not. Thanks for help noesges
