Very big thanks to the tech|inferno community!!! This is my first post. The forum actually was under revamp during my build, It was a good thing I was trolling this site for about 8 months and pretty much had the entire site in my web browser cache.

Time for the build. Akito Thunder 2 -I took the enclosure to the shop and hacked the case down to this. -Affixed what was left of the Akito to the SilverStone Case -I originally had the SFX 600W power supply. It arrived DOA. I strongly recommend not using the SFX PSU, It has a smaller louder fan. the SFX-L has a quiet 120mm fan that lines up with this cases vent holes -Paper Clip trick (pin-out diagram in the manual, cables are black) -Time Machine Drive -Akito PCB -GPU + SSD -I used an expensive 3m PCIe riser cable (the ones with the blue tape from amazon are doo doo.

Goalque you are the man!!! I thought the OSX implementation was going to be difficult, but it was a breeze thanks to you. Here is a helpful youtube link to deploy the script (watch all of it before you begin). Software: Win8.1 (Master Boot Record) I had trouble installing Win8.1 MBR (I tried from Disk utility, and from windows install cmd prompt - diskpart to create a MBR partion, but I failed) I'm sure there is a better method, but this is how I did it: Bootcamp Assistant: remove the windows partition Insert install usb on left side USB port. Used bootcamp to install Win7, 1st step is creating the windows/MBR partition (if I broke the install process and tried to Alt/option to the usb installer I would lose the keyboard and mouse) Booted back into OSX and used bootcamp to create a WIN8.1 usb install installed WIN8.1 on the WIN7 partition. (Nando's DIY eGPU Setup 1.30 works best with MBR vs UEFI, which is the reason for all the fuss) Paypal $25 to Tech Inferno Faneva to get the DIY eGPU Setup 1.30 (best $25 ever spent) Very Special thanks to Nando for quickly responding to all my questions. He sent me a specific startup.bat and pci.bat for my GT750M All installation instructions are sent with the software in a very clear email. Install the CalDigit drivers for the Thunderbolt Station 2 (this caused me a bit of grief, I assumed the drivers were installed because my drives mounted when I booted with Just the TB hub) I used my wife's hair ties to firmly secure the eSATA cables to the hub. If they are slightly loose, the drive will still mount, but will not function or format properly.

If boots to black screen: turn off Laptop off, disconnect the eGPU thunderbolt cable, power cycle eGPU, power on laptop holding down "option", wait for the boot drives and the mouse cursor to appear, plug in eGPU thunderbolt cable, select drive If hangs at boot selection, power off laptop (leave eGPU connected and powered on), power on laptop Almost always works if it comes to this stage (keep in mind this is for my particular setup) Very pleased with ease of boot, I was experiencing nightmares during initial build. I can't thank everyone enough in the forums for sharing their experiences My question: Are there any OSX overclocking utilities, like afterburner? (before I start playing with the maxwell bios tweaker)
Hi, Used this great resource to build a eGPU based on a EVGA GeForce GTX 980 Ti Hybrid 6GB with a HighPoint RocketStor 6361A Thunderbolt 2 PCIe Expansion Chassis, Silverstone Milo ML08B-H Mini ITX Case with Handle, and Silverstone SX500-LG 500W Gold SFX Power Supply. My eGPU requirements are solely for daVinci Resolve on OS X to boost render times and size of files that can be rendered without the dreaded GPU Is Full message. No gaming, no monitor. Can’t get any simpler. The eGPU is to run on either a MacBook Pro Retina, 15in Mid 2015, AMD Radeon R9 M370X, and a iMac 27in Late 2013, Nvidia GeForce GTX 780M. Did a quick bride of Frankenstein build on the table to check it all works using the MacBook Pro. Downloaded the Nvidia Web Driver (346.02.03f04), downloaded and ran goalque’s installation script https://www.techinferno.com/index.php?/forums/topic/7989-script-automating-the-installation-of-egpu-on-os-x-inc-display-output/. Rebooted the laptop and there was the 980 ti in the OS X systems report. Ran Resolve and it recognised the card and rendered at approx 3 times the speed of the non eGPU render. Sweet! Spent a day doing the build, with loads of pics which I’ll post here soon. Carried the eGPU over to the iMac, plugged it in and went through the process again. Downloaded the Nvidia Web Driver (346.01.02f04)*, ran the script, rebooted the machine. In the systems report there is a new card recognised, but it has the generic name of NVIDIA Graphics Device. In Resolve it recognises the card as NVIDIA Graphics Device. I rendered the same file. On the Laptop I was getting 10fps, on the iMac I get roughly 7.5. Both systems were reading and rendering to the same external SSD and the CPU wasn’t being taxed. Hmmmm. So I search the site for NVIDIA Graphics Device and found a few post relating to Titan builds, but they are reporting expected performance. Again Hmmm. So my next step is to upgrade the iMac from 10.10.3 to 10.10.5 to match the MacBook Pro. I will also update the NVIDIA Web Driver as at the moment they are both up to date base on the OS X but do not match. I can’t find anything relating to 10.10.3 and NVIDIA Graphics Device but its the only obvious difference between the two systems. I’ll post my findings soon. Any thoughts? Cheers
