mPCIe/EC eGPU troubleshooting steps

Recommended Posts

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 from say http://www.bios-mods.com 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/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

I wanted to set up an external graphics card , so I purchased a PE4H ver2.4 + PM3N and a gtx 650 ti graphics card 2 gb

I had to buy a Diy setup 1.30 software, to install the graphics card port pci express . Again my bios had to be put in Legacy for that to accept the playback format hard disk MBR .

but the software does not work in the sense that it does not recognize the PM3N . Then I remove my internal wifi card defaulting because she had to take a lot of bandwidth . But it still does not work . In addition there has shed light on the pe4h .

Thank you cordially for your help Sebastien

Sorry I'm French .

Sebastien, I write this to you now a third time. Please perform this check:

Probably a whitelisting problem with the mPCIe slot. To get it detected boot Setup 1.x with the wifi card installed, then carefully unplug it, power on the eGPU and *really carefully* hotplug the PM3N end into the wifi slot. Then hit F5 to attempt to detect the eGPU. If detected OK then can try to use the PCIe ports->undo-whitelisting functions to bypass needing to boot with the wifi card in the system to get the eGPU detected.

Nando Yes I understood what you wanted me to try. But the problem is that I do not get there has to detect your method. Maybe I took half bad. If you could explain more precisely, or I can take picture of my pc so that you can better help me.

Boss nando please help me:48_002:

1. Try setting the PCI Reset Delay switch to 6.9s (SW1=3).

2. Then power on the eGPU and quickly power on the notebook. A RED LED on the PE4L will indicate when the PCI Reset Delay is active. Is will turn off after ~7s.

3. Proceed to boot Win7.

If the card isn't detected then you have a mPCIe whitelisting issue. To deal with it set SW1=1 (no PCI reset delay), install the wifi card, boot Win7, hit F8/F12 to halt the boot process, power on the eGPU, *carefully* swap out the wifi card for the PM3N, continue the boot process. The card should be detected at that point. If there is an error 12 against it obtain Setup 1.x to deal with it.

Hey guys,

I'm running a Lenovo L540 with the following specs:

Windows 8

Intel HD 4600 graphics

i5-4200 CPU

12 GB RAM

I am using the PE4H 3.2 adapter with an expresscard. My power is a 550 watt PSU hooked into the ATX slot of the adapter. The card I'm running in the adapter is a Radeon R9 270 OC. When I power up, the LED on the adapter lights and the fans on the card start spinning. My problem is that it seems like my system isn't detecting the card. I have nothing in device manager other than the Intel HD card. I know that I'm going to need to disable that to get the radeon to work, but until I can see the card in device manager, I don't see what else I can do.

I just ordered Setup 1.x, so I'm hoping that may help. Does anyone see anything I'm missing or have any suggestions for how to get my laptop to recognize the card? I have updated my BIOS and checked all the settings and that didn't give me anything either. Any help that can be offered will be much appreciated.

Thanks!

EDIT: Have Setup 1.x installed now, but when I select it as a boot device, I get the error: Remove disks or media. Press any key to restart

EDIT 2: I have succesfully booted into Setup 1.30, but now my eGPU isn't being detected. Any help or advice is very much appreciated as I am starting to hit a dead-end!

Hello all guys,

Let me expose my problem.

I've bought a nvidia gtx960 turbo 2gb ddr5 for my HP AIO m100ep...

I'm using a BEAST eGPU with mPCI-e interface but every time i start the PC the graphic card starts spining his fan too fast and the computer dont reconize it also.

It simply dont appear on the system...

I'm using a ATX PSU with 350W.

Can anybody help me? I'm been struggling against this for a long time. :ambivalence:

Pls refer to http://forum.techinferno.com/diy-e-gpu-projects/11393-mpcie-egpu-troubleshooting-steps.html#post149873

Hi, this is my first message and i see a lot of people rlly do a lot of work to help anothers. i want to thank all the people who will help me, i'm not a english speaker so i will try to write properly and explain you my case.

I have:

-Packard Bell EasyNote TK85 (similar to some Acer Aspire).

-i5 480m

-4GB Ram

-dGPU: nVidia Geforce GT 540m

-eGPU: nVidia Geforce GTX 550 Ti

-500W power supply.

I want to make an eGPU works because my dGPU is kinda broken.

I put all in position, and my PC doesn't recognize the card at all. I tried it on W10, seeing that didn't work on it i installed w7 on my PC t try with it and had the same result.

When i uninstall dGPU drivers and i instal eGPU drivers my PC recognise my 540m... so weird.. And there is a thing that is weird, if i turn on my PC with all plugged in and with power supply of the eGPU powered on, my screen laptop stays black, as well as my external monitor conected to eGPU and it stays some seconds running and it restarts then same happens again and restarts, that restart think has no end until i turn off my eGPU...

Hi everyone! I'm trying to build my first egpu setup and I have some doubts. Can i ask some questions about the PSU? I'd like to get some help, in order to avoid a massive explosion ahahah.

I'm going to use a Cooler Master 550W atx12v (with my Gigabyte gtx970 and Akitio thunder 2 PCIe box)

[ATTACH=CONFIG]16516[/ATTACH]

I saw in this guide that i have to plug two 6pin in the gtx970 and one 6pin in the Akitio using an adapted cable that will allow me to use the standard Akitio power input.

My questions are:

1) considering the fact that my PSU has three 6pin plugs, it's the same if i plug the P4 and P5 in the video card and then i use the P6 for the Akitio, or are they different and so i must know where which one of them must go in?

2) for the first question, i supposed that a 6pin plugs is 12v. It's right? And how can i know the A of these 6pin plugs? I saw that original Akitio psu is a 12V 5A. On the PSU there are written six outputs specs and no one has 5V for 12V.

I'm so confused. Is this PSU ok for the eGPU system that i'm trying to build? Of course I'm not going to turn it on without this information and without being sure that it's all plugged in the right way. I'm sorry for my ignorance and for my bad english. Thanks to everyone who's going to help me! n.n

Hey I was wondering if I could use this to help me get my Lenovo U310 to recognize my GTX 750 ti. Thanks!

 

Computer Components:

Core i3-3217U

BIOS - 65CN99WW

 

Tried list:

1.) Normal boot, PCIe slot 1 (wifi original slot)

2.) Normal boot, PCIe slot 2 (ssd original slot)

3.) Wifi card hotswap w/ computer in sleep mode. (this caused the computer to shut off when trying to wake from sleep. Computer booted with black screen.)

4.) Worth mentioning that I did this with a non-WL'd BIOS.

I got my Gtx970 recognised under windows 10 after hotplugging it for the wifi card while in sleep. But i get error 12 so i tried DSDT override..... that didnt work, windows 10 gave me bluescreen, AICP BIOS ERROR and windows 7 booted but didnt have Large memore in device manager and the sleep function has since been grayed out. Anyway when i boot into DIY egpu setup it tells me i have an unknown INTEL processor so it tunrs of iport functionality. Without that i cant access the PCIE  Devices menu, and therefore also not the anti whitelisting menu. I dont know how i can get my egpu to detect in setup or how i can get the setup to recognise my cpu correctly and enable iport functionality. If anyone knows soemthing that might work, that would be great. 

 

I have a chinese laptop with:

i7 4710MQ

16GB ram

250GB Samsung 850 mSata SSD

1TB HDD

 

Also i dont get the option to disable my dGPU it just says dGPU on demoted,  couldnt really make sense of the help description either.

I'm trying to setup an eGPU on a Thinkpad T440p. 
I have a GDC V8 with GTX470 powered by Dell DA-2, connected via M.2 (A+E key) to the motherboard. 


When the computer boots I get 5 beeps and a blank screen, which seem to indicated a "system board error".

Disconnecting the cable and everything runs as normal. 

 

I'm not sure how to proceed from here. I heard Nando is back so the setup1.3 software is back on the menu; will it help?

Anyone with a Thinkpad - chip in your experience.

Both your dgpu and egpu are allocated ok. With the egpu powering off, check you power leads and psu attached to it.

 

That's the thing. As long as windows doesnt start PSU stays working. As soon as the windows logo comes up on boot after a few seconds, The PSU shuts off. Could it be the mPCIe cable?

That's when the egpu tries to send output to the attached lcd which requires increased poer. If the power drawn by the egpu then is greater than the max of the psu, or the psu is faulty, then the psu will power off.

 

Pls try another more powerful psu.

Ooh never thought about that. Thanks. BTW should it be able to work without any setting changes like without running Setup 1.3?

windows 10 pro 

and wanting to use the m pci-e beast v8.0 to run gtx970 

 

Plugged everything in and powered on fine . The 970 was  Initially  detected but after installing the nvidia  driver it wont detect the 970  just the 750m .

Yes the PSU was faulty. I tried the GPU and it works. Now I want to troubleshoot a few things. My eGPU doesn't show display. It works, it shows up correctly and CPUZ even detects it. But when I ran a GPU stress test my Laptop's dGPU started to work and it got to 105'C which lead to thermal shutdown. Why didn't it work? I have set my dGPU to a lower priority via Setup 1.3? Would I need to disable my dGPU?

      Hello everyone.
       
      I put on a eGpu setup after quite a bit struggle 2 years ago and I used play games just fine. After a while I sold my graphics card gtx 970.
      Now since 2 days I am trying to put the eGpu setup back again this time with a Gtx 770.
      I couldn't understand the problem. I can shut my dGpu off with diy 1.30 setup. ( usb booted)
      And my laptop sees  gtx 770 along with my igpu Intel HD graphics 4000.
      After driver installation when I try to play a game laptop is tring to use iGpu instead of Egpu. (tried to delete and install driver few times)
      With MSI afterburner I can see  eGpu is  %0 all the time.
      Can it be power problem cause graphic cards fans ( Msi gtx 770 twinfrost ) are working all the time they dont stop.
      Or what else can it be. 
      Thx.

      In case you own a Lenovo Y410p or Y510p laptop, you might be interested in upgrading its performance by installing an external graphics card. Ultrabay eGPU adapter designed by @gerald was proven to be a convenient plug-and-play option to do exactly that. However, for a long time only an AMD-branded GPUs could be used due to limitations in the Lenovo's stock BIOS. The purpose of the modified firmware presented here is to expand the range of available GPUs by enabling Nvidia support on Gerald's Ultrabay eGPU adapter.
       
      Huge thanks to:
      @MWichni - For efficiently assisting me during the development of this mod. By flashing dozens of BIOS builds over the course of several weeks and thoroughly describing the effects observed (or the lack thereof), he enabled me to fully understand necessary parts in BIOS structure and come up with a final solution. @svl7 - Whose unlocked BIOS / Whitelist mod has served as a basis for this modification. His discovery of a security hole in V2.07 BIOS has provided us with a convenient BIOS flashing method that does not require a physical programmer. The Unlocked BIOS and WLAN whitelist mods originally designed by him are also implemented in this BIOS mod. @gerald - For designing the aforementioned adapter. Without it, all this work would make very little sense.  
      Key features:
      Resolves the "40-second reboot" issue normally encountered while using Nvidia graphics cards with Ultrabay eGPU adapter, thus allowing all Nvidia cards to be used. Based on the latest V3.08 BIOS. Includes Svl7's WLAN whitelist removal mod - for the convenience of aftermarket WLAN card users. Includes Svl7's BIOS debug menu mod - for the ease of experimentation with newly available features, e.g. attempting to use Nvidia Optimus to pass eGPU video back to laptop's display.  
      NB! Svl7's Debug Menu is not a toy! It contains a lot of options that are either not supported or partially supported by the hardware platform and/or can disturb its normal operation or prevent the PC from booting up at all. Any of the entries not originally present in the stock BIOS should be modified at your own risk!

      Error 43:
      If you intend using the GTX10XX-series Nvidia card as the eGPU (which you probably do), you are very likely to encounter the infamous Error 43 in Windows Device Manager. This is a widely known issue in the eGPU community and is not related to this particular mod in any way. Following this guide thoroughly will in most cases resolve the Error 43 issue.

      Hi to everyone , I have troubles to eliminate the error 43.
      I have beast 8.0
      EXpress card cable
      cx650M Source power
       
      I have tried  to install different versions of driver nvidia but the error persists.
      When I start the laptop and the power supply at the same time I have a black screen. but if I wait about 10 minutes  and then I turn OFF the laptop the restore computer appears , seems like  the laptop worked normally (but I have no video signal).
      Sorry for my poor english.

      Hallo Leute,
      Ich habe mir zu Weinachten eine Akitio Thunder 2 mit einer EVGA GTX 1060 6gb für meinen late 2013 IMac mit einem 120W AC Adapter von Leicke geholt.
      Zu meinem Problem, Ich habe alle mögliche Treiber probiert ich habe mein Windows zweimal neu aufgesetzt und
      habe verschiedene Sachen im Geräte Manager deaktiviert. Was kann ich da jetzt noch machen das die evt. doch geht?
      Danke schon mal im voraus
      Harry

      So my laptop (latitude e6430) has an expresscard, so I wanted to get a eGPU for it. I did some research, and already got the adapter, but theres one thing I need. I need to know what is my TOLUD and what GPU should I buy for it, respectively. Here I attach a screenshot of my device manager and my laptop's specs so that someone may help me. If I got this right, my tolud should be 3.5Gb. Is this true, and if so, what GPU should I buy?
      Processor: i7-3520M
      RAM: 8GB
      note: sorry that the screenshot is in spanish, but I dont think that should matter
