Dell Inspiron - iGPU & dGPU but want to add eGPU!

Hi,

After a day of fiddling this forum is my last resort - willing to buy Setup 1.35 if that gets it working.

The Dell Inspiron 5547 has 8GB RAM, Intel Integrated Graphics 4000 plus a dGPU Radeon R7 M265. The eGPU that I used to try-out was Radeon HD4500 (just to try out!). The eGPU adapter is GDC EXP Beast V8 connected through NGFF2. The BIOS unfortunately is not helpful at all - no settings to turn on/off anything - no way to turn off the dGPU.

I've tried a lot, but definitely:

- turning on the laptop with everything connected -> black screen, no boot

- turning on the eGPU after Windows boots -> keyboard no longer functions, but graphics card not detected

- ONCE have I seen the eGPU in the Device Manager, but no display output - I think this is after removing the other AMD driver and while coming back from sleep - after reboot it was gone and I've never seen it again.

- the EXP GDC seems to work fine, have plugged in a Soudblaster Z and that works OK - detected and everything. I can even leave that plugged in.

- key problems:

1) hangs in BIOS if booted with eGPU, sometimes even repeatedly boots and shut down - only to give a very loud beep in the end

2) keyboard no longer functions with eGPU detected (this is weird I think)

3) Maybe the fact that the eGPU (to try) is also AMD is causing issues? In the end - if everything all works - it will be NVIDIA so if that's an issue I'll try to rule it out.

I read a lot on the forums about turning off the dGPU - I wish I could figured out how! Also read about having more than 4GB being a problem? And is DDU specific for NVIDIA?

Any help very much appreciated!

Hi Nando,

I already tried most of the things from the link you posted. In particular:

set the PSU to be permanently on to help troubleshooting

This was done using the small switch on the GDC EXP. The LED is now on permanently.

error 43: NVidia driver 372.90 and newer on non-hotpluggable mPCIe/M2 interfaces

error 43: running a NVidia dGPU and eGPU

I'm not using any NVidia GPU (yet).

error 43: incorrect eGPU initialization due to PSU mistiming

not sure where I'm supposed to get error 43 - I haven't seen it, but then again: my eGPU isn't shown anywhere.

mPCIe/M2: eGPU doesn't get detected

This is the case. But using a non-GPU PCI-E card (SoundBlaster Z) works, so it doesn't seem that BIOS whitelisting is in place.

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

Not sure - if this were the case, would the SoundBlaster Z work?

eGPU still not detected: faulty hardware?

Done - not faulty.

NVidia driver stopped responding" intermittent messages: can't run Gen2 signalling

Not seen, not using NVidia card (yet).

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

Not sure how I can see whether this port 'disappears'? Can I see this in Windows?

A black bootup screen or ACPI_BIOS_ERROR windows bootup BSOD

This *is* happening. 

I will try to use GPU-Z and see if that reveals a bit more. 

 

Meanwhile, where can I read up on PCI compaction to see if that could be the solution?

PCI compaction is part of the DIY eGPU Setup 1.35 tool. See details about it at https://egpu.io/egpu-setup-13x/

I'm sorry but this is no longer necessary - after an evening of plugging in/out & reboots, the processor broke (!) - now the only thing the $600 laptop does is beep 7 times 🙁 🙁 🙁

I guess that marks the end of my eGPU endaveours... If anyone wants to buy a hardly used EXP GDC V8 with NGFF cable, please DM.

hi, i have the same laptop and is working... for me i did...

"Boot with wifi card into nando's eGPU Setup 1.35 carefully hotplug the eGPU adapter in place of wifi card. Hit F5 to rescan the PCIe bus"

EXACTLY WORKS... then next install drivers with 
DESHabilitar DRIVERS FIRMADOS
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS

bcdedit -set TESTSIGNING ON

HABILITAR DRIVERS FIRMADOS

bcdedit -set loadoptions ENABLE_INTEGRITY_CHECKS

bcdedit -set TESTSIGNING OFF

then works perfectly but every reboot you need to do this...

Hey joseitoz, I'm dealing with the same problem that you were and I'm only able to detect my egpu by hotswappingwith theWiFi card too.
I haven't been able to install drivers tho because anytime I shut down it goes back to the black screen, and a shutdown is required to finish installing the drivers. Was just wondering what you meant by installing with DESHabilitar DRIVERS FIRMADOS and setting load options

hi sorry by my english... i mean you need to do hotswappingwith theWiFi card too.
then when you are in windows.. go to CMD like administrator and put this:
(dissable firm drivers)

bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS

bcdedit -set TESTSIGNING ON

so you go to drivers nvidia modifed and install... whitout reboot
and when you done put this: 
(available firm drivers...)

bcdedit -set loadoptions ENABLE_INTEGRITY_CHECKS

bcdedit -set TESTSIGNING OFF

and everything back to normaly....

now every reboot you need to do hotswappingwith theWiFi card too. but no drivers...  write for twitter @joseitoz if you have any question...
