eGPU shutdown underload

Recommended Posts

Hey guys,

i have just build my eGPU set up,

-2015 Macbook Pro Retina 13″

-Akitio Thunder 2

-Zotax GTX 1060 Mini

-450 PSU

 

I installed everything perfectyly and everything works both in Mac OSX and Windows 10 Bootcamp, after 2 days of using it without major issue(other than succesfully booting up), today something weird happend. While i was playing CSGO(Less than 1 hour), i hear some flickering sound, it was weird but i choose to ignore it, then after a while the CSGO stopped suddenly. I ran it back and it continue without any problem.

After playing i intend to check my GPU by testing the Unigen Heaven benchmark, while testing for about 5 minutes, i hear more flickering sound, my GPU fans spins weirdly, sometimes it spin very fast, sometimes normal and vice versa and suddenly it all stopped. My egpu fans shuts off and windows cant detect my external gpu hence benchmark was stopped.

i restart my mac and run the benchmark again, after a while the eGPU turns itself off again. I then thought it was some benchmark issue, then i play H1Z1, also around 5 minutes, my eGPU turns off again. The last two days, my eGPU has never turned itself off, and it was very stable, no matter what load i give it, it will run perfectly fine.

Anybody can shed some light?

Thanks

UPDATE: the auto shut off only happen when i put a pot of stress to the GPU, if i were to play moderate games, it is stable

I used to have a similar problem and it was power-related. Try using msi afterburner and capping the power to like 85 instead of 100 and see how it goes.

Yes, you can choose whatever gpu on the settings, brand/maker/chip, whatever. Be careful, it's main use is for overclocking, I'm just using it to "underclock/limit the power".

Good luck!

So i have not tried using the afterburner, but sometimes the eGPU would just work smoothly with no issue at all. And sometimes it would turn off by itself in both OSX and Windows

So... try it in windows? If its what I say it could be just when the gpu starts demanding more juice, and would make sense to happen in both win and osx.

On afterburner choose in settings your egpu, put the power limit to 85 instead of 100 - don't change anything else -  and play for some time or make some stress tests with some benchmarks.

I tried using msi but still after a few minutes the fan speed up and eGPU is disconnected

Hmmm sounds like it could be overheating, you could check how the temperatures rise and compare it to other people's cards? Maybe it can be hardware related (damaged card) or your case isn't ventilated enough? Its probably turning off so it doesn't burn itself as a safety measure.

I doubt it is overheating, because i just ran heaven for 3 minutes and it disconnected, and fan is normal, temp is below 55. Before disconnecting, the fan would ramp itself to max and then disconnects.

could you try the gpu on a normal pc? It might have something to do with your akitio box setup? At least to rule out a damaged gpu card...

I have tried it, and it worked perfectly fine with no issue, even after giving it a 1 hour stress test it still works well

I think it has something to do with my power delivery for the akitio box, i read online that i can use a pcie riser(with power), and i do not need to power my box because the adapter already gives the power? Is that true?

I just solved a similar issue with my old Akitio T2 using a GTX 970. Every time I'd load the unit up with a game or unigine, the computer would crash. Ended up being high resistance in the molex-to-barrel harness where I'd soldered the joins. 

Are you using the stock power pack for the akitio or have you put a molex-to-barrel in?

I used molex to barrel adapter. First i use molex adapter to 2.1 x 5.5 then another barrel adapter to 2.5 x 5.5 so that it can fit. So are you saying my adapter is not good? What could i do to fix it?

I'm not saying it's not good, just that mine wasn't. Wiggle those connections when it's on and see if you can simulate the problem. 

The crackling sounds you're hearing before crash definitely sounds like a power issue, once the card draws/wants more power and can't get it it will go into panic and restart the computer. 

How have you hot-wired the psu?

I don't know much about powered risers, but every post I've read with people saying they're going to use one has been told not to do so. 

You should be able to run the set up the way you have it configured. 

Double check all connections and make sure they're clean and tight, get some canned air and blow out connections to make sure there's no dust/dirt in any ports. Dust where it shouldn't be can cause all sorts of headache.

When i wiggle the connection, sometimes the akitio turns off. I use the normal paper clip trick. So i need to get a new barrel connection to solve the issue right?

so i should change my adapter to solve the issue?

That's more than likely your issue. If there's not a solid connection there when the aikito draws full power it will drop out, which makes sense with your symptoms. 

Heres what I did:

1) use the barrel plug off the akitio power pack! Cut it off with a decent length of cable to use to join it. It's a coax style cable, so bare back the outer insulation about 5 or so cm and twist the outer braid into a 'wire' and bare back the white wire. The white is + and the twisted braid is earth. 

2) test which wires are supplying the correct voltage for the akitio. I think it's 5v but check before you do anything else. Go to an auto parts store and buy some "red bullet connectors" and connect the white wire from the barrel plug to the 5v + from the connector you have and the twisted outer cable to ground. 

3) voila! Done. You now have a solid power connection. I found the barrel connectors you buy don't fit neat, which is why you're having problems.

      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?
