Hello,
I have RX580 and it's detected (by @nando4 help :)) and setup all above but I got blue screen error with "ACPI BIOS ERROR". I'm stuck with it for weeks 🙁 I've try to run other PCI compaction as Nando comment but the same result so he said maybe it's not compatible with this bios model.

My notebook spec.: Acer Aspire 4752G / i7-2760QM / RAM 8 GB / Windows10 / BIOS version 2.19

My eGPU gear: EXP GDC 8 with mPCIe / MSI Gaming RX580 8 GB / DIY eGPU Setup 1.3x 

Setup in BIOS:
- Network boot: Disabled
- Graphic mode: Integrated

Setup & Status in DIY eGPU Setup 1.3x:
- HM65: gen=2 p=8 tolud@3.49GB
- DSDT: yes
- PCIw: yes
- using_devcon_text: yes
- all_alloc: yes[64MB] ------------------
- iGPU=8086 : 0126 (Intel)
- eGPU=1002 : [email protected] (ATiAMD)

Do you have any ideas for this issue?

Thank you.

@nokhuakwan - Try forcing PCIe speed to gen1 to check whether you are experiencing PCIe signal integrity issues.

Hi, 

Have you try enabling hotplug for your mPcie port?

Hi, 
If you mean enabling hotplug by modding bios, no I'm not do mod bios yet but if you mean doing hotplug by using DIY Setup eGPU, yes it can do hotplug and detected my eGPU adaptor. I'm not sure this reply answer your question or not. 😕

I was having the same issue before but by enabling hotplug I get mine working. 
I'm using grub to modify the key to enable hotplug. But your case maybe different with mine before. 

Have you try different gpu?

Thank you for your advice Smile I will try enabling hotplug with this method.

Before I get my RX580 I borrow GTX1060 from my friend and it works fine as an eGPU.

Just update for my case, now eGPU(RX580) works. Big thanks to @nando4 with a lot of helps and thanks @jkeychen for this topic and another old topic with Acer 4752G and also advice for enabling hotplug by mod bios method and @burnok for instruction of modding bios to enabling hotplug (link locate in the first post).

Conclusion:
- Got ACPI BIOS error. @nando4 found out my loaddsdt is the cause of error so skip running "call loaddsdt" by edit startup.bat
- Hijack PCI config space by enable dGPU in bios then Setup 1.35, hotplug eGPU, run PCI Compaction for eGPU with ignore dGPU then dGPU[off], startup.bat and chainloader.

@jkeychen, I was expecting to apply this guide, even when looks really hard, but i was surprised, when i did connect my RX470 with the cheap mining riser to my Asus X452CP in the WiFi Slot.. and surprise, it was detected instantly as the RX470, may be it happened because the internal dedicated GPU is an R5 M240 Radeon and the driver software apply to all radeon graphics. I have not make anything, non disable the internal dedicated GPU, either the HD graphics and i have not still test the GPU on any stress benchmark, curiously i used an external TV by HDMI and works well, and i disconnect the TV and the Laptop screen worked too. The only weird thing that happened to me, was that when the RX470 reach almost 70W trying to play  in comsuption while playing Horizon Zero Dawn (cracked version), the generic power supply i have turned off, so i guess that a benchmark will fail easily.  By the way, Horizon did'nt run good, but tomorrow i'll test again Horizon, BF4 and GTA V.  Bye and i'm happy.

 

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
