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.

 

Hardware

 

 

The Hardware Test - OSX 10.10.5/DaVinci Resolve

-NYC Gaffer

-Aspiring cinematographer, needed more horsepower to hack at my 6K footage.

-Constraints of living in New York, desktop is not an option.

-Test was a success! Time for the build.

 

Akito Thunder 2

-Affixed what was left of the Akito to the SilverStone Case

 

IMG_1992.thumb.jpg.78f15f64a617822f93218

-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. You can see the quality of the solder points on this cable)

-I've read plenty of horror stories of people blowing out their GPU or mobo using cheap cables

-Molex to Barrel to power the Akito PCB

-CSGO setup is not so different, just add Steel Series Mouse, Big mouse pad, 7.1 headset, and keyboard (but in Windows)

 

Software: OSX

 

  • OSX 10.10.5 - I was stumped for a few hours because I needed to use version 0.9.6 vs 0.9.7 of goalque's script because I have a dGPU

 

  • It seems like he's solved this issue with 0.9.8 which is great (0.9.6 was really hard to find).
    • 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).

 

5682202b13763_ScreenShot2015-12-28at10.5

 

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.
  • Disabled windows Paging and hibernation
  • Windows automatic login

 

Overclock eGPU:

 

  • MSI Afterburner
  • (+125) 1490 Mhz core on boost
  • (+505) 4009.5 Mhz memory
  • 64.4% ASIC quality
  • 110% power limit
  • 87mV
  • 91c temp limit
  • custom fan curve
  • ~74c Load, 50-60% fan speed

 

Under-volt CPU with Intel Extreme Tuning Utility:

 

  • I've been getting through the benchmarks with -74mV, but I would crash after an hour or 2 of intense gaming
  • been testing -53mV right now for stability
  • Macsfancontrol to boost internal fan controls

 

Benchmark results
 

3dmark13-FS=13228

Unigine Heaven Benchmark 4.0 score: 2091

Valley Benchmark 1.0 score: 3488

 

Startup procedure

 

  • Laptop off, eGPU thunderbolt cable connected to port closest to MagSafe, power on eGPU, power up laptop.
  • 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)

Great setup! Unfortunately there is no tool for OSX to OC the card. The only way would be to mod the BIOS.

If you have in Windows a constant CPU load of 10-20% without doing anything, try this:

- boot into Windows

- set Mac into Hibernate mode

- power on MacBook and boot again into Windows

 

On some games it is also nice to limit the CPU clock speed to sth like 3GHz, which results in much lower temperatures (with the lower voltage) and stable CPU clock speeds.

Hello Jmlee5,

I have very similar usage for my MBPr mid2014 GT750M.

Thanks to goalgues's script egpu setup on OSX 10.10.5 was flawless.

I am using Akitio box, Zotac GTX970, CHIEFTEC Smart Series SFX-500GD-C power supply for GPU and Akitio.

It is working even on restart. With 400W cheap power supply I have to hot plug Akitio so I have changed power supply.

 

My main goal was to using it for DaVinci Resolve, but gain over GT750M in rendering is only 3-6 fps (usually only 3fps). But playback of 3.5K Alexa 4444XQ footage is jumpy, stuttery and eventually stops. Without eGPU, playback is steady.

 

What is your experience with DaVinci Resolve in OSX? Can we compare rendering times and usabilty?

 

Is enyone else is willing to try transcoding on various setups with CUDA acceleration (or Open CL) in DaVinci Resolve so we can compare.

Davinci Resolve is free and it is very easy to do testing if we use same footage and same export encoding settings. I can provide guides.

 

Cheers

Hello guys, and JMlee5,

 

I also have a Macbook Pro Retina 15 late 2013 with the Geforce 750M. I am interested in making a very similar eGPU setup, running Windows 10 (or 7 if I must), and using the internal LCD, not an external monitor.

I will be using a EVGA GTX 760 and Akitio Thunder 2.

 

I am pretty clear on the hardware side of things, but not the software...

I am trying to figure out if I need to use the DIY eGPU 1.3 setup software to make it work. Or does it work just plugging the eGPU in and booting windows? Will windows recognize the eGPU without aditional software?

 

I am very new to this, so forgive my noobish questions. Any help would be greatly appreciated! Thanks!

@Necemon I can playback red 6K footage at 1/4 res at 23.98fps. In windows when I overclock the card I can get 16 fps at full res 6K. If I modify the bios I'm sure I can pull down the same speeds on OSX. I don't have any Alexa footage on hand. I can try and get my hands on some and do some tests. Are you east coast? 

 

how fast are your drives? If your media is on a spinning hard drive I would bet that's your main culprit. 

 

@maarten the answer to your question is no, windows will not recognize your eGPU without additional software. You will get an error 12. 

 

You don't need to purchase the DYI eGPU setup it just makes things easier. I would say I'm pretty tech savy, but doing the DSDT overrides myself is a bit out of my depth. What really impressed me was Nando's support. He answered most of my questions within a few hours, even on Christmas Day. (Def worth the $25)

 

@Dschijn I followed your advice running my cpu at 3.0ghz everything runs super cool/stable, no matter how much abuse I throw at it. Rock solid advice. Thanks!!!

Hi

On the photo ipad? How they are connected? What is this software?

 

How do you know what you're running GT750M = GUI in Davinci? How much shown video card in the preferences Davinci? Only 980 or 750 too?

 

Thx

Artem

In windows it shows video card 1: GeForce GT 750M - GUI only, Video card 2: GeForce GTX 980 Ti

 

In osx it only shows the gtx 980 Ti, but performance is the exact same as in windows (and the eGPU can not drive the internal display)

 

The Ipad 2 is using "air display" as a 2nd monitor (i suggest using duet instead, 60fps on the ipad)

 

The ipad retina is using "VS element" connected via tangent hub.

The app is free for one hour each day. But keep your eyes out for the tangent ripple. It's a control surface for $350 coming out soon.

Thank you very much for the answer!

I have a titanX+750m, but in settings Davinci appears only Titan, how to fix it? (i have full version Davinci)

I think it's a bug. Both GPUs are doing what they are supposed to be doing. It just doesn't show up in the preferences. 

 

As stated above, everything displays properly in my window's preferences, but only my 980ti shows up in osx. Performance is the same between both operating systems.

 

In both of our builds the 980ti and the Titan are overkill for our CPUs and akitio.

@Jmlee5  I successfully added the GTX 980Ti to my mid 2014 rMBP dgPU using goalque v 0.9.9 

 

But the card is seen by the system but not by the programs, am I missing something? the monitor is not detected by the system 

 

Did you need to run "nvram tbt-options=\<00\>"  for the dGPU

when i ran it I got: 

nvram: Error setting variable - 'tbt-options': (iokit/common) general error

 

I am wanting to use it for CUDA programs like Resolve and 3D

any help would be greatly appreciated TIA

No real and easy way to make it work on the internal display for games!

 

It's not goalque-script-easy, but I regularly LAN party without an external monitor, using my eGPU for Optimus, on my dGPU-equipped MBP. Details and process are in my build thread:

Also, OP: nice setup! I'm jealous of your Ti.

      We've had a stack of recurring questions from with problems getting a mPCIe eGPU working. This includes GPU-Z not reporting no clock details, error 10/43 or even not being detected at all. Overall it's more troublesome getting mPCIe working than say expresscard or Thunderbolt.
       
      Here's some common problems and some troubleshooting steps to correct them.
       
      Getting a black bootup screen, resolving error 10/43 or ACPI_BIOS_ERROR win bootup messages
       
      Here the BIOS doesn't know what to do when it sees an eGPU. So the solution is to not let the BIOS see it. Do that by setting the delays on the eGPU adapter (CTD/PTD - EXP GDC or CLKRUN/PERST# on PE4L/PE4C). Boot with eGPU adapter in the wifi slot into Setup 1.30 or Windows. Is the eGPU detected?
       
      I'll add that should error 43 continue AND you have a NVidia dGPU as well as NVidia eGPU then it's likely because of having the mobile NVidia and desktop NVidia drivers loaded simultaneously. Proceed to uninstall ALL your NVidia drivers, use "DDU" to clean NVidia registry entries and do a 'clean' install of the latest NVidia desktop driver.
       
      mPCIe port that hosted the wifi card disappears when connecting an eGPU in it's place
       
      Use the Setup1.30 PCIe Ports->enable to enable the missing port.
       
      eGPU does not get detected
       
      Overcome mPCIe whitelisting by booting with the wifi card and then hotswapping in the eGPU. That way the BIOS will enable the mPCIe port to work.
       
      1. Boot with wifi card into Windows, sleep system, swap wifi card for mPCIe eGPU adapter and ensure eGPU is powered on, resume system. Do a device manager scan in Windows. Is the eGPU detected?
       
      2. Boot with wifi card into Setup 1.30 *carefully* hotplug the eGPU adapter in place of wifi card. Hit F5 to rescan the PCIe bus. Is the eGPU detected?
       
      If this enables detection then avoid this tedious hotswapping by seeking a unwhitelisted modified BIOS for your system OR test the Setup 1.30's PCI ports->undo_whitesting feature.
       
      eGPU still not detected - set the PSU to be permanently on
       
      The latest EXP GDC and BPlus eGPU adapters try to manage the PSU to only power on after they detect a signal. This can cause a race condition where the eGPU isn't ready to go when the CLKRUN signal is asserted.
       
      Avoid this by jumpering the PSU so it's permanently on rather than being managed. Depending on the PSU you are using refer to the following doco on how to do that:
       
      http://forum.techinferno.com/enclosures-adapters/8441-%5Bguide%5D-switching-atx-psu-using-paperclip-trick-swex.html
      http://forum.techinferno.com/enclosures-adapters/9426-220w-dell-da-2-ac-adapter-discussion.html
       
      eGPU still not detected - a non-standard mPCIe implementation by your vendor?
       
      PERST# mPCIe pin 22 may need to be isolated due to a non-standard implementation by your notebook vendor: http://forum.techinferno.com/enclosures-adapters/10812-pe4x-series-understanding-clkreq-perst-delay.html#post142689
       
      eGPU still not detected - faulty hardware?
       
      If you still don't get detection then test the video card and eGPU adapter in another machine to confirm neither is faulty.
       
      NVidia driver stops responding
       
      EXP GDC, PE4H 2.4 and PE4L 1.5 all use a socketted cable and therefore are not true Gen2 compatible device. This error indicates there was transmissions errors.
       
      The solution is either to get a better Gen2-compliant eGPU adapter such as PE4C V3.0 or PE4L 2.1b (both with soldered cable), or downgrade your link from Gen2 to Gen1 using BIOS options or Setup 1.30

      Required items:
      1.) Lenovo u310 (I have a Core i3 - Ivy Bridge, 8GB RAM)
      2.) 65CN99WW unwhitelisted.
      3.) eGPU (I used a EVGA GTX 750 Ti from another computer I had).
      4.) EXP GDC mPCIe Edition adapter (got from eBay - banggood seller).
      5.) ATX power supply (I used a 600W PSU from another computer I had).
      6.) USB wireless.
      7.) External monitor, keyboard, and mouse.
       
      Steps:
      1.) Obtain and install a unwhitelisted BIOS. If you are unable to obtain a unwhitelist BIOS, I think it might be possible to bypass it with Tech Inferno Fan's Setup 1.x (may need confirmation as I haven't used it myself yet.)
      2.) Shutdown computer and remove all USB devices, ethernet cables, power cables, card reader cards.
      3.) Remove mPCIe wireless card and detach antennas.
       
       
      4.) Attach EXP GDC external mPCIe cable to the former wireless slot and screw down.
       
       
      5.) Attach HDMI end of the mPCIe cable adapter to the EXP GDC device.
       
       
      6.) Attach graphics card to the EXP GDC device (I moved my laptop off the desk and onto the side shelf to make room on the desk for the monitor/keyboard/mouse).
       
       
      7.) Using the power cable adapters that came with the EXP GDC device, I hooked in my ATX power supply's 20 pin and CPU 4 pin cables. Then hooked the other end (8 pin) into the EXP GDC device. My EVGA 750 Ti also required that I use an additional PCIe power cable (6 pin) in the top of the card.
       
       
       
       
       
      8.) Then I attached my misc devices (HDMI monitor, USB keyboard/mouse/wireless adapter), and hooked in my PSU and powered it on (below is image of final product, also moved HDMI cable out of the way).
       

       
      9.) Power on your computer and let it install the standard VGA drivers and then install your drivers (I didn't have to go in the BIOS for any graphics settings, which it doesn't have anyways, nor did I have to disable iGPU in Device Manager before the card was added).
       
      Extra Info:
      I found that most games will play on med settings with about 45 FPS with this particular card.
      BDO: Upscale on - Anti Aliasing on - SSAO off - med settings.
      Skyrim: Med-High settings.
      Fallout 4: Med settings.

      Hello, A couple of days ago I got a new GPU but when I installed it into my computer I was unable to use it but now I know why. When checking the device manger I went into the events tab of my GPU when I went to view all events, I noticed an error it said " event 411 kernel PnP " and It also said Problem Status: 0xC01E0438. I believe this is why my GPU hasn't been working on my PC. If you know how to fix this problem or have info on how to fix this problem that would be greatly appreciated. I'm also using a EVGA NVIDIA GeForce GTX 1660.
    • By TheLoser1124
      I'm having a problem where my PC is saying my eGPU is not usable, its detected in the Device Manager and it doesn't have the yellow triangle next to it. I cant use it games and the Nvidia Control Panel doesn't recognize it either. I'm using a EVGA NVIDIA Geforce GTX 1660. I'm using windows 10 and I tried DDU and reinstalling them and now I cant access the nvidia control panel. The GPU is not recognize on any other apps and I went on *********** and was unable to find my answer, Any help on how to fix this problem would be greatly appreciated.

      Title sums it up.
       
      TL;DR: we have a Clevo that runs a desktop CPU, one with those huge 82 Wh batteries. We remove the GPU and let it use the CPU's integrated graphics. How much time for the battery to go from 100 to 0? Is it comparable to an ultrabook's?
       
      I'm theorizing a mobile set with a static eGPU and an upgradable CPU. Given a hypothetical user that needs fast processing on the go and long battery life while retaining very high degrees of mobility, but at home wants a powerful machine to run most games, I guess that would be their best bet. It would surely be more convenient to keep everything in the same disk. And even though the thing would be quite heavy to carry around, changing CPU would be more cost-efficient than changing an entire laptop. (Not sure if I'm right here, and also I'm not sure whether the motherboard in a Clevo would be replaceable when the new CPU needs a different socket, which is another reason why I'm asking here.)
       
      If my above guesses aren't correct, then an ultrabook with Thunderbolt and without a dedicated GPU would be a better choice. If they are, then we would be carrying more weight in exchange of a more cost-efficient setup, which I think would be a fair tradeoff.
       
      Also I am aware of the heating problems that these laptops suffer from, at least compared to a desktop setup. Would they be solved by moving the GPU out of the chassis, and instead plugging it with an eGPU dock via Thunderbolt port?
       
      What do you think? Is it doable? If not, why?
