I’ve had a stack of recurring offline questions from users with problems getting mPCIe, expresscard or NGFF.M2 eGPU adapter interfaces working. This includes GPU-Z not reporting no clock details, error 10/12/43 or even not being detected at all.  mPCIe and NGFF.M2 are more troublesome getting going than say expresscard or Thunderbolt.

Below are common problems and how to correct them:

 

eGPU is detected but has error 12. See these software solutions:

https://egpu.io/forums/pc-setup/fix-dsdt-override-to-correct-error-12/
https://egpu.io/egpu-setup-13x/

 

error 43: NVidia driver 372.90 or newer with GTX10xx cards on mPCIe/M2 interfaces

NVidia driver 372.90 and and newer have been found to cause an eGPU error 43 when hosted on non-hotpluggable interfaces (mPCIe, M2) using GTX10xxx cards.  For workarounds see:

https://egpu.io/forums/expresscard-mpcie-m-2-adapters/nvidia-is-killing-off-mpciengff-m2-egpus-error-43-with-372-90/

  

Set the PSU to be permanently on to help detection and error troubleshooting

BPlus eGPU and EXP GDC eGPU adapters by default only enable PSU power upon detecting a PCIe signal. This can cause a race condition where the eGPU isn’t ready to go when the PCIe CLKRUN signal is asserted.

The fix is to jumper the PSU so it’s permanently on rather than being eGPU adapter managed.

BPlus PE4C 3.0 can set a the PWR ON jumper shown with yellow arrow on the far left here to do that.
EXP GDC has a ATX PWR switch shown here to do that.

If neither of those switches is available, then manually power ON your PSU with these instructions:

ATX PSU:  http://aphnetworks.com/tutorials/psu_paperclip_trick pictured here
Dell DA-2: bridge [remote+GND] pin 5+6 with a paperclip.  (another  pic). Explained here.

Doing this will greatly assist further troubleshooting.

 

error 43: incorrect eGPU initialization due to PSU mistiming

Use GPU-Z software to check if your clock information is being reported correctly. If not, then your eGPU isn’t initialising properly. This can happen due to incorrect clock timings. Ensure you have set your PSU to be permanently on as per previous step.

 1. Set the delays on the eGPU adapter (PTD – EXP GDC or CLKRUN/PERST# on PE4L/PE4C). Boot into Windows or Setup 1.35. Is the eGPU detected with correct clock info reported by GPU-Z?

 

error 43: running a NVidia dGPU and eGPU

If you have 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 disable your dGPU, uninstall ALL your NVidia drivers, use “DDU” to disable automatic driver installation and clean NVidia registry entries. Then do a ‘clean’ install of the latest NVidia desktop driver.

 

A black bootup screen or ACPI_BIOS_ERROR windows bootup BSOD

Here the BIOS doesn’t know what to do or mangles the ACPI when it sees an eGPU. The latter preventing Windows from loading successfully. So the solution is to not let the BIOS see the eGPU. A couple of ways of doing that as below. The PSU must be set to be permanently on as described above for this to work.

1. Set the delays on the eGPU adapter (PTD – EXP GDC or CLKRUN/PERST# on PE4L/PE4C). Boot into Windows or Setup 1.35. Is the eGPU detected? Note: if this bypassed the black bootup screen then you’ll probably find a reboot will again black screen the system.  This delay works when doing a cold boot from the system being powered off.

2. Start the system without the eGPU adapter interconnect HDMI cable disconnected(eg: between eGPU adapter and EC/mPCIe/M2 end).

– halt Windows bootup with F12/F8 attach your interconnect cable. Is the eGPU detected in Windows device manager?
– or boot into Setup 1.35 , attach your interconnect cable,  hit F5 to scan for the eGPU. Is the eGPU detected?

3. With no eGPU attached:

– halt Windows bootup with F12/F8 hotplug your eGPU adapter interface. Is the eGPU detected in Windows device manager?
– or boot into Setup 1.35 , hotplug your eGPU adapter interface, hit F5 to scan for the eGPU. Is the eGPU detected? If the eGPU isn’t detected, bootup with wifi connected into Setup 1.35, hotplug your eGPU interface, hit F5 to scan for the eGPU.

 

mPCIe port that hosted the wifi card disappears when connecting an eGPU in it’s place

Use the Setup 1.35 PCIe Ports->enable to enable the missing port.

 

mPCIe/M2: eGPU doesn’t get detected

Likely due to BIOS whitelisting preventing the port from being enabled when a non vendor device is detected. Overcome by booting with the wifi card and then hotswapping in the eGPU. That way the BIOS will enable the mPCIe port to work. A few ways to do that:

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 1.35. *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 1.35’s PCI ports->undo_whitesting feature.

 

mPCIe: eGPU still not detected – a non-standard vendor port implementation?

PERST# mPCIe pin 22 may need to be isolated with a very thin piece of cellophane tape (sticky tape) like shown due to a non-standard implementation by your notebook vendor causing CLKRUN/CLKREQ initialization mistiming. See PERST# pinout. Asus notebooks known to suffer from this issue.

If you are absolutely unable to boot and hotplug the eGPU on your T530i, try to tape (isolate) pin2 aka the 3.3v_RUN of the GDC mpci-e connector like this, it solved all my cold boot issues! SRC: wimpzilla.

 

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.
If using an EXP GDC adapter then consider testing a US$7 mPCIe eGPU adapter [PCE164P-N03] (inc NGFF M.2) instead.

 

“NVidia driver stopped responding” intermittent messages: can’t run Gen2 signalling

EXP GDC, PE4H 2.4 and PE4L 1.5 all use a socketted cable and therefore have shown Gen2 signalling issues. This error indicates there was transmissions errors. If have another video card test it as subtle impedance differences between vendors can cause these errors.  Also try isolating your PSU to it’s own power outlet, not using any USB devices in the eGPU adapter and even wrapping aluminium cooking over the eGPU adapter’s connecting cable (between system and eGPU adapter) to isolate EMI noise.  For the EXP GDC, if handy with soldering, consider making your own interconnecting cable. Also consider adding power cabling ferrite beads.

The other solution is either to get a better Gen2-compliant eGPU adapter such as PE4C V3.0 or PE4L 2.1b (both with soldered cable).

Finally, if Gen2 cannot provide a reliable link, downgrade your link from Gen2 to Gen1 using BIOS options or Setup 1.35.

 

 The eGPU stops working after some time of use

This can be either a PSU or video card stability issue with the factory settings which may be clocked beyond what the components can handle. For the latter, downclock your video card by 15% – core/mem/target power using MSI Afterburner. If the problem persists, then swap your PSU for a known good one and test again.

Also try isolating your PSU to it’s own power outlet, not using any USB devices in the eGPU adapter and even wrapping aluminium cooking over the eGPU adapter’s connecting cable (between system and eGPU adapter) to isolate EMI noise.  For the EXP GDC, if handy with soldering, consider making your own interconnecting cable. Also consider adding power cabling ferrite beads.

Lastly, set your power profile->CPU max performance to 99% to turn off CPU turbo multipliers that may be causing CPU overheating. REF: maverick234

 

The eGPU is reported as running at x1 1.1 link speed in GPU-Z rather than x1 2.0

Click the “?” next to Bus Interface to perform a render test. This will take the eGPU out of lower power x1 1.1 Gen1 mode and (usually) switch to x1 2.0 (Gen2) mode.  If it still remains in x1 1.1 mode then you can uprate your link from Gen1 to Gen2 using BIOS options or Setup 1.35.

 

Error 31 against the eGPU “The device is not working properly because Windows cannot load the drivers..”

Power management L1/L2 (L01/L01) could be switching off the hosting PCIe port as discussed.  Disable L1/L2 mode in your BIOS to fix.

I also have an EXP GDC 9.0b and both switches are missing (empty solder pads). I asked the seller about it through taobao and they kept repeating that the switches weren’t necessary. Surrounding pads are blank too, so I don’t think it would work to simply add a switch or jumper.

The 9.0b is also failing to run at PCIe 3.0 x4; I can only get 2.0 x4 and 3.0 x2 (1 cable) working properly. I’m going to try a different brand M.2 -> x4 adapter that looks more promising.

Hi,

I have a Dell E6430 laptop with an Intel 4000 integrated gpu. I am trying to upgrade it to a GTX 1050 TI eGPU with the GDC Beast expresscard adaptor and a 450W power supply while using the internal display.

The problem is that when I plug the GPU into the laptop after startup, the gpu is not recognized by the device manager. When I try to download the Nvidia driver from the CD and the website manually, it gives me the “Nvidia cannot find compatible hardware”. When I plug the GPU into the laptop before startup, I get a black screen and my laptop starts up, as I can hear the startup screen, but the screen stays black. The light is on for the GPU and the fans are spinning.

My laptop seems to recognize the GPU because it acts differently on startup when it is plugged in, but doesnt recognize it if I plug it in after. I have tried to follow some BIOS setups like disabling Wake on LAN, NIC onboarding, and Integrated NIC. I also tried to use DDU to unistall both the intel GPU and the Nvidia GPU while restarting. I have tried to use an HDMI from the eGPU to an external display and get the same black screen. I also tried it on another laptop and the Nvidia showed up in the device manager on that laptop.

I followed the steps of the link below, which is using the same setup but with Windows 8.1 and I could not get it to work.   https://egpu.io/forums/implementation-guides/dell-latitude-e6430-zotac-gtx-1050-ti-mini-via-exp-gdc-8-4d-expresscard/

I am just trying to play PUBG! Please let me know if there are any suggestions, Thank you!


So building off of my post above….

I ended up getting setup 1.35 and got my laptop to recognize the card and got an error 43 and decided that I was just going to switch from the gtx 1050 to a 960.

So now I did that, used DDU to get rid of all previous Nvidia drivers. My laptop now gives me an error 12 with the new 960. I tried to use setup 1.35 to get rid of the error 12 like I did with my 1050. Except it doesn’t work. I tried the steps in both of the videos and it defaults to my Intel 4000 when I run the test chainloader after compaction.

I don’t really want to get into all the windows files to change the dsdt if I don’t have to. Any ideas?

Thanks!

Hello everyone

plz help me. I have an HP Elitebook 8570p with an EC slot and an EXP GDC 8.4 with an EVGA gtx 780. it was still ok until today when I am playing Rise of the tomb raider and suddenly I was out of the game with something related to Nvidia driver as i remember.

And now I cannot start my eGPU. It ran for a few seconds and then it shut down . I wonder if it has problem with my ATX psu. besides, i am using Hunkey LW6500HG

It could be a faulty PSU, video card, eGPU adapter or (most likely) eGPU adapter cable. Try reseating all cabling and see if get detection. If not, swap out individual components with known good working ones until identify the faulty component.

I could start it again a few minutes again and it ran for a while. Then it shut down again with a blue screen “dumping” as I remembered. I restarted my laptop and watched some videos on Youtube. It was still ok

Hi there people. Hopefully you can give me a hand. I´ve tried to get this going with no luck. I have a EXP-GDC v8.4 on an HP Envy M4 (M4 1150la) via PCIe to a Gtx660 and an old HD4870.

HD4870 results in a no detection at all of. No image on my external monitor and i belive it does not get detected at all (didn´t find it on device manager).
I don´t even know if EXP GDC gets detected with no GPU.

On the other hand with the Gtx660 i just boot to a black screen but loads Windows 10 completely (got to know by plugging/unplugging USB and hearing system sounds). 
BUT! when i boot with no EXP-GDC and i go to devices manager, under “Hidden Devices” i can see that Gtx660 has been installed (or at least detected as shown on the SS attached). 

Sooooooooooo… any idead of how am i supposed to proceed or what to do? 
Thanks in advanced!

I´ve being  playing with following BIOS setting: Secure Boot (disabled), Legacy (Enabled/Disabled) and just for a chance Virtualization (Enabled/Disabled).

Hello everyone,

I have a small problem with my eGPU. My laptop is HP Elitebook 8570 with an EC slot and my eGPU with a GTX 780 still ran perfectly. The thing is when I play game for too long like today i am playing Rise of tomb raider , it suddenly shut down and I can only restart it after a few hours.  What is my problem:  ATX Psu, GPU or both? Besides, I am using Psu Hunkey green power 6500 second hand and I doubt it is the cause. 

Please help me and thanks in advance

Seems to me like temperatures or failure in driver. Try 1st reinstalling drivers. Also watch temperatures and try replacing heat compound.

is is possible that the fan on GPU itself has died?  

If you can start and run it for few minutes, then it is more than likely a thermal shutdown – GPU reaches a critical temperature and shuts itself down to prevent suicide. 

Can you borrow another graphics card from a friend, etc. just to try?

Hello! Here is a new test with Lenovo T540p with GTX970 via expresscard Exp GDC Beast.

There is no dgpu on the t540p, the geforce driver are installed, GTX970 is recognized in GpuZ but not functionnal for the moment.

No boot If the expresscard is plugged, I can plug it when I have thinkpad logo. No sign of life on external screen via hdmi.

With the T530 I just had to plug hdmi at the prompt for windows password.

I will try with older drivers.

edit : i have bought DIY eGPU Setup 1.35 , hope it will help.

Hello I am brand new to these forums, I held from joining till I got my first egpu working so I wasn’t talking out of my a** haha, BUT I successful set up my first egpu and I was blown away that it actually worked! Right out of the box too! I ordered what I assumed to be the EXP GDC Beast v8.4 (I’m not sure how to tell what specific model it is) (says Beast Pro on the mPcie) and i connected it to the port on my HP Pavillion m6 1035-dx and viola! I installed the latest nvidia driver for my 750 ti and it worked like a dream! So I uninstalled the drivers and then used my spare R7 370 (since it has 4GB of VRAM instead of 2) and here is where things got a little hairy so I have some questions you might be able to answer or have seen before.

TL;DR I have a working egpu and I just have a couple questions.

1.) In GPU-Z, the link speed for my eGPU fluctuates from “x1 1.1” to “x1 1.2” to “x1 2.0” while I’m doing various tasks, is this normal? Why does it change frequently?

2.) I did some benchmarks with the R7 370 installed and I left my computer while it was running and when I came back the screen was frozen and I couldnt do anything but I could still hear the music playing. Any ideas to what that was? The same thing kinda happened when I was using the benchmark utility on rainbow six siege, i clicked the desktop then came back and it crashed my external display and froze in the same fashion. But later I played the actual game for about 2 hours and no crash (GPU load was only at about 64% the whole time)

3.) I can not run Furmark on my external display, and it will only run with my integrated graphics, any fix?

 

Thanks for the help and I’m so glad I found a community of egpu enthusiasts. 

 

EGPU SETUP:
HP Pavillion m6-1035dx i5-3210m
EXP GDC v8.4 mPcie R7 370 4GB

My laptop is the Toshiba P205-S6337 with an ExpressCard slot. I’ve attached a GTX 460 to it and am using a 550 W power supply. I initially had Error 12 but solved that by performing the DSDT override and then hotplugging my GPU in the Windows 7 boot menu reached when holding F8. Now I’m facing Error 43 and am unable to solve it. I have tried the latest drivers (384.76) as well as a driver from years earlier (270.61). I’ve set the jumper on the GDC 8.0 to have the power supply always on and have experimented with PCI Reset Delays but I always get Error 43. I have tried to sleep and then wake the device but the error does not disappear. GPU-Z does not display the clocks for my GTX 460 and says it is 0 MHz. My BIOS has Wake-on-Lan disabled and I have no dGPU; the iGPU is the Intel 945 GM. I would appreciate any help! Thanks!

hello everyone, I had a previous account but I forgot the password after logging off so I created a new one  . I am having an issue with trying to get my egpu to detect. I have an exp gdc beast v8.0 and I’m trying to use a gtx 650 on it. My psu does not have a 6 pin connector for the gpu so I’m using 4 pin molex to 6 pin connector to give additional power to my gpu but my gpu still does not detect. Also I have tried using a gtx 1050 and I got it to detect but it kept giving me error 43. I tried  booting my laptop with the wifi card in and then removing the wifi card and plugging in the egpu to bypass any bios whitelisting but it still does not detect. Any help will be extremely appreciated.

2.Ran DDU  removed all drivers and reinstall. code 43 …

Next I try a specific version of the driver, such as  368.81 ,378.57

but

I don’t know if I have to modify my bios to enable hot plug, or use DIY eGpu tool

I need more help ,thx.

I don’t think I’ll ever get the joy of rigging an egpu to my potato laptop (n5110 i5)

Problems : 

1. Card detected and driver installed. Code 12

2. Trying to do dsdt override gives acpi error bsod (egpu not even connected. dsdt file issue?)

3. Boot with egpu gives error “connect all pcie devices xyz”

Undo whitelist and restore port – stuck at line 3, for ever. Am I doing it right? 

5. Only way for card to detect is boot normally – sleep mode – swap to beast card. 

 

Is there any solution or am I pursuing a lost cause?

Hi all

I have a dell latitude E6400 with

smartcard
ExpressCard 54 (pin’s not the ones that look like sata)
Firewire
blue toth (WPAN/FCM/UWB)
dialup modum (WWAN/FCM)
i394
wifi card (WLAN/WiMax)

 

I orderd a EXP GDC beast but it didnt have the right pin’s and was to nearow for my port.

 

I also orderd a DIY $9 mPCIe and 8pin to 2x molex(for the grafics card). I pluged the mPCIe in to the wifi card (WLAN/WiMax) port.

Ween I try to install driver “384.76-desktop-win8-win7-64bit-international-whql” It sayes “NVIDIA Installer cannot continue” “This graphics could not find compatible graphics hardware.” during “System Check”.

I have a MSI GTX 960 4GD5T OC and FlexATX 300w PSU.

Hello Guys, jumping in straight with the facts

-Lenovo Y570 (i5 2430M, switchable Intel HD3000 and NV GT555M (disabled))

-EXP GDC 8.4b with MSI AMD R7970 connected with mini PCI express

-Windows 10

-tried Windows Energy Settings PCIe Savings options

-tried RMPcieLinkSpeed registry settings with values from 4 to 0

(all with no result 🙁 )

-aside from that, card is working relatively fine

(((obviously link speed test was performed with GPUz link speed render test and/or games/benchmarks playing))))

 

 

The card will only work at PCIe x1 1.1, the platform should support PCIe 2.0 though.

Weird thing is, the onboard GT555M, while being an x16 Link (as expected), also only works at Gen 1.1. (should support up to gen2.0)

How can I fix this issue?

Thank you guys

I have a Lenovo Thinkpad T420, and I bought a EXP GDC Beast to use my graphics card with it, however when it’s plugged into the Express Card slot, all it sees is the USB to HDMI adapter.   Not sure what else I can do

Hello.

I seem to have run into a dead end here.

CPU: i5-2410m, 8gb ram

Motherboard: ASUS K54LY, Intel HM65 chipset, bios is newest, unmodded

iGPU: disabled in manufacturing

dGPU: AMD HD6470m

eGPU: ASUS RX 560 2gb without 6pin

Here are some things I have tried out:

Scenario 1:

Remove WLAN, insert the EXP GDC. no delay/ 7s delay/ 15s delay and ATX switch on/off do not provide different results.

Result: Laptop stuck pre-post, power-on led turns on, does not show the splash screen, does not show any hdd activity nor does the usb keyboard work. The eGPU fan does spin.

Scenario 2:

Boot up with the WLAN inserted, put laptop to sleep, replace the WLAN with EXP GDC, wake laptop up again.

Result: Windows detects the GPU, but error 12. The eGPU fan does spin.

Scenario 3:

Insulate the pin 22 on the mpci adapter, try no delay/ 7s delay / 15s delay and ATX switch on/off without any difference.

Result: Laptop boots fine, but neither Windows nor Linux detect the presence of anything in the mpci slot. The eGPU fan does spin.

On the EXP GDC itself, the green led always stays on (should it not turn the led off once the delay has passed?)

I also tested the EXP GDC on a old Thinkpad X300, it worked with leaving all the switches stock.


Update:

Scenario 4: Currently the best working one

Boot up with the WLAN inserted, switch it out for the EXP GDC while on the OS selection screen.

Result: Evertything detects the GPU, on Windows with a error 12.

Need to do a DSDT edit as egpu setup did not manage to free enough resources with compaction, setting the dgpu to off and disabling the pci port of the USB 3 controller etc.

The TOLUD value reported is 3.0GB, large memory area missing from Device Manager. Will also later check what Linux will do with pci=noacpi boot parameter.

 

It is however a little bit masochistic to constantly hotplug it whenever I need to reboot.

ASUS seems to have implemented something non-standard on my laptop as the exp gdc seems to halt its post, not even reaching the ASUS logo on post, as for some other ASUS users.

As far as I know, ASUS does not whitelist their ports, so it must be some initialization problem.

In the past I upgraded the firmware of my USB 3.0 controller to one without the ASUS signature – that caused the laptop to restart twice at post before successfully booting, but the controller worked. Flashing a ROM with the ASUS signature fixed this issue. Could be related to how it does the check.

Theoretically PIN 22 insulation should have fixed this issue, but for some reason it makes the card not show up at all, it also makes no difference in which position the delay slider is in, the gpu fans always start up instantly without the green led ever turning off. I also found that insulating the PIN 2 works for some, tried that, no go.

Next off I should unlock my bios and see if I can disable any power management or detection parameters on the mpci port, so I could bypass the post halt.


Update:

Got it to work on Linux. This was the first time I ever saw anything displayed on the egpu on this laptop. Used the Scenario 4 brought up earlier, set pci compaction on and etc, then booted linux with pci=nocrs, had to blacklist the radeon kernel module so it would pick up amdgpu instead. Saw very noticeable gain in performance in Trine 2 for example, and both external screens worked.

Next up I should edit the DSDT for Windows as I am fairly positive it will work.


The DSDT edit did work on Windows. Running RX560 @ 1x 2.0. Still need to hotplug during boot to bypass the bios post halt.

 Hello, this is my first post so I need a little guidance here, so I am trying to use a GeForce GT 620 on an EXP Beast through MPCIE, with my Toshiba Satellite c55dt-a5106 on Windows 10, and when I first cold plugged it, the computer showed it as VGA adapter, but with error 18, so I installed the latest drivers from Nvidia, and I restarted the computer after it installed, as directed by Nvidia, but now it only either ends up with BSOD when starting up, or it stops booting at a black screen with a text cursor in the top left corner of the screen. When I boot into safe mode, it boots correctly, and is recognized correctly as GeForce GT 620. Does anyone have any ideas?

Hi all

I have a dell latitude E6400 with

smartcard
ExpressCard 54 (pin’s not the ones that look like sata)
Firewire
blue toth (WPAN/FCM/UWB)
dialup modum (WWAN/FCM)
i394
wifi card (WLAN/WiMax)

 

I orderd a EXP GDC beast but it didnt have the right pin’s and was to nearow for my port.

 

I also orderd a DIY $9 mPCIe and 8pin to 2x molex(for the grafics card). I pluged the mPCIe in to the wifi card (WLAN/WiMax) port.

Ween I try to install driver “384.76-desktop-win8-win7-64bit-international-whql” It sayes “NVIDIA Installer cannot continue” “This graphics could not find compatible graphics hardware.” during “System Check”.

I have a MSI GTX 960 4GD5T OC and FlexATX 300w PSU.

Ok so I have tryed the wightlist hotplug switching and the taping over the 22pin on the mPCIe adapter and pc can not see the eGPU. What now ?

I dont own the Setup 1.35

Shuld I look for a adapter that will plug in to my ExpressCard 54pin port ? It wuld have to be a ExpressCard 2.0 to ExpressCard 54 1.0 .
