  1. Hi there, lots of useful info on here! Still I need to ask a few questions as my setup isn't quite working! I've a 2012 rMBP on El Capitan 10.11.2 and I used the automate_eGPU.sh script to quickly sort out the modification of files and installation of NVIDIA web drivers. I'm testing it with an NVIDIA GTS450 which is connected via a Sonnet Echo Pro and PE4C 3.0. SW1 is set to 2 (PERST# delay 9.8sec), SW2 to 1 (CLK no delay). It's picked up fine in OS X and I can drive an external monitor with it no problem. However, it doesn't appear to be doing any rendering - all the legwork is still being done by the internal GT650M!!! It shows each screen as being driven by the GT650M in About This Mac, and testing with games seems to corroborate this. What gives? I can't find any examples online of other people who've had this problem (at least in OS X). The GTS450 is correctly identified in System Information. A second question... I know there isn't a way to get the output on the internal LCD on Windows on this Macbook due to it having a dGPU and Apple's rubbish firmware, but is that the case in OS X? The Intel HD4000 is accessible there, does that mean I could funnel the graphics back to the internal LCD or is it just impossible on all counts?
  2. hi guys! I need help with my egpu. My gtx 970 with the akitio 2 works fine on my mac mini on os x 10.10.1. mow I tried it on my Macbook pro mid 2012 15" with the same os and it doesn't work. The gpu isn' recognized, System information I get NVIDIA Chip Model instead gtx 970. The drivers are the same as on my mac mini.
  3. First off I want to say thank you to the community here. I wouldn't have been able to do any of this without the hard work and dedication of everyone who blazed the trail before me and shared their experience. I wanted to post my success story in case others were trying to do something similar. Hardware 15" MacBook Pro Retina, Mid 2012 2.6 GHz Intel Core i7 (Turbo boot to 3.6 Ghz) 16 GB 1600 MHz DDR3 Sonnet Echo Express SE II Asus NVIDIA GeForce GTX 980 4 GB LG Ultrawide 34" 34UC97 curved 4K display [3440 x 1440 @ 60 Hz] Apple Cinema Display 20" (2006 or 2008, I forget) [1920 x 1200] OS X (worked on both 10.10 Yosemite and 10.11 El Capitan I've been successfully using my eGPU under OS X for over a year. Thanks to Goalque's Automate eGPU script. Really is super easy. Major props. Some thoughts, in no particular order Original setup was using the MBPr in clamshell mode in a Hinge Dock --> Did not work well, issues booting, internal screen stayed on Updates can randomly break everything --> easy fix with the automate eGPU script Very stable --> quite pleased with the success Windows 10 Just got this working last weekend. I originally used bootcamp, which on my device sets up windows to use MBR. Could not get it to work even with the help of Setup 1.30 / 1.2. Out of boredom I nuked the windows partition and re-configured everything to boot EFI. I eventually got everything working using the DSDT override. Some additional thoughts, in no order The integrated Intel GPU causes all sorts of trouble. Windows updates drives a lot without telling you. Causes blue screens. Needed to keep disabling the device in safe mode This slowed down and frustrated the process, often times I didn't realize the integrated GPU was causing issues I believe the DSDT override was done correctly, and after that everything began working correctly (the large memory device is in device manager, but there is nothing below it) My game of choice is Heroes of the Storm. Conveniently I can test it in both windows and OS X. It runs much better in OS X Seems to be CPU limited. In OS X Turbo boost is constantly overclocking to 3.4 GHz. CPU temp in the mid 90s. Fans at Max. (GPU does not seem pushed, fans slow). 50-70 FPS @ max res, mix of Ultra on more GPU intensive settings and Low on CPU settings In Win 10, Turbo boost was all over the place 2.8-3.2 GHz. Game was much choppier. 25-60 FPS. CPU temps were ~102. Same settings. I have screenshots of everything. Unigine Valley benchmarks in both OS X and Win. I'll add tomorrow. Realize this may not be a great guide for others trying to replicate, but wanted to share my success story as a guide post for others with similar hardware. And to say thanks again to the community. I've been an avid reader of the guides and other builds as I worked through mine. Feel free to ask any questions. I'll help where I can.
  4. Original Author: tranj10 After two weeks of fiddling around with my eGPU setup I have finally found a method that works well with my hardware. There are many suggested modifications on this forum (Evo*'s modified boot files, DSDT overrides*see note bottom of post, DIY eGPU setup), but it seems that these modifications are not necessary for the 2015 13" MBP. The setup includes easy plug-and-play hardware setup, fairly easy software setup (little bit of command line), and installation of Windows 8 on an external drive. Many users with 2015 MacBook Pros seem to have trouble booting up consistently with the eGPU on 2015 MacBooks, so hopefully the power up process I've found works on other MacBooks. Hardware: AKiTiO Thunder2 PCIe Box ASUS DC MINI NVIDIA GTX970 (fits in AKiTiO case without physical modification, but unable to close the case) Dell DA-2 AC Adapter Samsung T1 Portable SSD Cables: These cables from ebay are what make the hardware just plug and play Akitio Egpu 8 Pin to 2 x PCI E 6 Pin Super Low Profile No Latch 1 x Barrel | eBay Two PCI E 6 Pin to One PCI E 8 Pin 90 Degree Bend Right Low Profile USA Made | eBay Hardware installation: - Do not use the PSU that came with the AKiTiO enclosure - Really simple installation, just plug everything in (there aren't many cables and ports to figure out). Just make sure none of the 6-pin and 8-pin plugs are upside down, but it should be easy to tell. Note that for my software installation below, everything was done right after I reset the MBP to factory settings. eGPU and OS X: Goalque's automate-eGPU.sh script makes OS X very easy to setup for eGPU use. (http://forum.techinferno.com/mac-os-x-discussion/10289-script-automating-installation-egpu-os-x-inc-display-output.html) 1) Boot into OS X without eGPU connected 2) Download automate-eGPU.sh and then move it to desktop 3) Press command + space and type in terminal to open up a terminal instance 4) Run the following commands in the terminal - cd ~/Desktop - chmod +x ./automate-eGPU.sh - sudo ./automate-eGPU.sh 5) Go through the commands with "y" and then shut down 6) Go through the Power up process described below Bootable Windows 8 on external SSD: Follow this detailed guide (BleepToBleep: Mac: Install Windows 7 or 8 on an external USB3 or Thunderbolt drive without using bootcamp) - In step 3 part 1, enter the command 'cd C:\imagex' (or wherever you put the imagex.exe file) eGPU and Windows 8: 1) Boot into Windows 8 without eGPU connected 1a) Install Boot camp drivers if not done so already. 2) Perform Windows Update ignoring the suggested intel graphics update (not sure if ignoring intel graphics update is neccesary) 3) Download latest NVIDIA drivers 4) Power on eGPU and connect the thunderbolt cable to the MacBook 5) Check Control Panel > Administrative Tools > Device Manager > Display Adapters for a new display adapter entry 6) If nothing is there or you got a BSOD just restart MacBook and try again 7) Install NVIDIA drivers, selecting custom installation, and include all the options 8) Shut down 9) Go through Power up process described below I sometimes run into a Windows 8 boot up hang, but they don't seem to happen often so just power off and try again. Power up process: This is the power up process I always use to consistently have a successful boot without any black screen issues. 1) Have everything powered off 2) Connect thunderbolt cable to eGPU and MacBook 3) Power on the eGPU power supply (use a power strip with on/off switch) 4) Wait ~15 seconds 5) Power on the MacBook while holding option key 6a) Select the boot partition you want 6b) If you run into a blank black screen: - Force power off for MacBook - Power off eGPU power supply - Disconnect thunderbolt cable from MacBook - Power on the MacBook while holding option key - Boot into OS X, log in, and shut down - Go back to step 1 (there will be no black screen issues for at least the next boot up) - If you still are getting black screens after repeated tries then try a NVRAM clear (https://support.apple.com/en-us/HT204063) - Note that the NVRAM clear does mess with the changes implemneted by automate-eGPU. So you'll need to run 'sudo ~/Desktop/automate-eGPU.sh -skipdriver' to re-enable the changes - If the NVRAM clear doesn't help then try enabling -a mode with automate-eGPU by running 'sudo ~/Desktop/automate-eGPU.sh -a' Benchmarks: I have run 3DMark Fire Strike on the internal display and external display for the GTX 970 at stock manufacturer settings. - There is a 18% difference between internal and external display graphics performance - There is a 16% difference between external display eGPU and desktop GPU graphics performance - The external display eGPU (stock settings) performance is on par with the top overclocked desktop GTX 960s Here is a link to the comparisons: Results - They are ordered as: Desktop GTX 970 (stock) | Desktop GTX 960 (overclocked) | external display eGPU GTX 970 (stock) | internal display eGPU (stock) - The cpu is definately a bottle neck Thanks to @goalque for all his help in getting my setup for the 2015 MBP up and running! I would be interested in knowing if my power up process works for others out there, or if it's just a fluke. I am not sure if every step in the process is necessary (booting in OS X versus just waiting with everything off) edit: I went through this procedure a second time for a clean install, and it still works mostly fine. For some reason now only the thunderbolt port closest to the MagSafe port works for eGPU recognition in Windows 8. Both ports are usable for eGPU in OS X though. edit2: I am using the dsdt override as suggested here (http://forum.techinferno.com/diy-e-gpu-projects/7476-%5Bguide%5D-dsdt-override-fix-error-12-a-2.html). It doesn't seem to hurt or help, but I am just noting what I am using now.
  5. A new OS X 10.9.5 update has just been released. If you are going to update to the latest version, you will loose compatibility with the old OS X NVIDIA web driver. Do the following to re-enable your driver with the new update and new NVDIA web driver.1. Update to 10.9.5 2. Download and install NVIDIA Cuda 6.5.18 here http://us.download.nvidia.com/Mac/Qu...4.01.03f01.pkg You will not be able to install the web driver because it will not recognize your hardware; [EDIT] this step can be skipped if you downloaded a modded package.[ATTACH=CONFIG]12589[/ATTACH] Follow the steps here on how to skip the hardware verification
