eGPU for Five (5) Monitor Setup?

Recommended Posts

Hi everyone.

 

I am looking for some direction/advice on setting up an eGPU for my rMBP.  I am more of a software and cloud networking guy then a hardware/graphics guy - so I am out of my area of expertise here.  Any assistance is greatly appreciated.

 

NOTE: I have a multiple display/monitor addiction.  The more monitors the better - and that is the main reason I am here. 

 

My current setup:

Mid 2012 rMBP

2.3 GHz Core i7

8GB Ram

NVIDIA GeForce GT 650M 1024 MB integrated graphics

Two (2) 1080p 24 inch external monitors (one connected via thunderbolt port, and the other connected via HDMI)

One (1) 1080p 21 in external monitor (connected via the other thunderbolt port).

 

So yes, I am running three (3) external monitors off of my mid 2012 rMBP.  And, it actually runs fairly well.  Include the rMBP display, and I am running a four (4) monitor setup.  I can usually have youtube playing on one monitor and browsers on the other, while still maintaining decent performance.  I am actually really surprised at how well it works for a 4+ year old computer.  However, there are some apps that I run which require me to unplug one or two of the monitors, and the rMBP is almost always running hot.  And obviously, I can forget about doing any kind of high-end gaming (which I rarely ever do at all).

 

Where I am going:

My company is giving me a spec'ed out mid 2015 rMBP (which I should have in a few days).

Mid 2015 rMBP

2.8 GHz Core i7

16GB Ram

AMD Radeon R9 M370X 2048 MB (dedicated GPU)

 

I am very excited to get a nice spec bump over my 2012 rMBP, especially going from 8GB to 16 GB ram.  And I am sure performance will be that much better with my three (3) external monitors attached.

 

What I want:

More monitors!  4k monitors! Here is the setup I would like:

My new mid 2015 rMBP docked (probably using something like the Henge vertical dock station). 

Run five (5) external monitors - one vertical and 4 horizontal.

Monitor (1): Supplement the rMBP display (since it will be stowed in the dock) with a 24 inch 4k monitor.

Monitor (2): Another 24 inch 24 monitor

Monitors (3), (4), and (5) - these no NOT have to be 4k.  Will probably just use the three (3) external monitors I already have (mentioned above).

 

Priorities:

Gaming is NOT my priority.  If I can play GTA 5 in ultra mode - great! But I would consider that an extra benefit.  I rarely play new games.  I am more of a 16-bit, 2D platformer guy.  I have done some VR development, and if I could run the Oculus Rift or Vive - then that would be really nice.  

 

My main priority is to power all these monitors while removing at much load as possible from the rMBP - so that I can run virtual machines/edit video/have 50 chrome tabs open - all while playing and HD youtube video (you get the idea). 

 

Here are my questions:

(1) Will using an eGPU offload a lot of processing power so the rMBP can concentrate on running many apps at once?

(2) If games are not a priority, are there graphics cards that may be cheaper which are designed for running more monitors vs. powering games?  Or is it all one in the same?

(3) I notice that many GPUs only have 2 or 3 video out ports.  How can I go about connecting 5 monitors to the eGPU - if it is even possible?  Or, would I still need to run one or two monitors directly off the rMBP?

(4) Am I missing any details/information/questions that will be important?  What am I missing or not thinking of?

 

Thank you in advance for all and any advice.

1. yes. the pixels in your extermal monitors will be pushed by the egpu instead of your mbp's gpu. However, the internal display is tricky to get running from your egpu especially since your new mbp has a dGPU included. Processing apps etc still run on the mbp's cpu, except for rendering scenes and videos etc, so thats that.

2. Workstation GPUs exist out there that focus less on gaming and more on professional setups. Using these as an egpu is less common and i dont know much so i will let someone else answer this.

3. If your egpu doesnt have sufficient ports, you could consider daisy chaining some monitors if they allow you to, eg the thunderbolt monitors. Its basically pluggin monitor A into the egpu, then plugging B into A,... It should work. Depends if your specific monitors allow that though. You may wanna consider looking for GPUs with more ports preferably since there are tons of brands out there anyways. My rather basic 1060mini already has 5 ports- 1 hdmi, 3 displayports and 1 dvi, and if you get something similar just hook up adaptors and run as many from the egpu

4. Some insight: gaming GPUs  are powerful too and also can run many monitors with ease. I suggest looking up reviews of such setups and what gpus they use. Take note of the various resolutions too; five 4K monitors is very different from 5 1080p monitors.

 

All the best!

Most Nvidia cards have hard limit of 4 displays. (regardless of how many ports)

 

Might be able to use MBP to do 5th

      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.

      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?
