hi guys,

in desperate need of assistance in getting an EGPU to work on my HP 840 G3:

Laptop specs:
  • HP 840 g3
  • I7 6600U
  • 32gb ram
  • 500gb ssd
Egpu:
  • Beast EGPU
  • M2 ngff cable
Gpu: MSI RX 570 8GB OC

Now, all of this worked perfectly via the express card on my older laptop but this isn't as easy. Over to this HP - I've taken out the wifi card and installed the cable in correctly. Set the complete egpu up and powered on the 840 G3.

What I get is constant boot cycles, Acpi bios errors and not reading the card... I have tried everything and even paid and downloaded Nando DIY EGPU setup. I had installed this software correctly and all is well in terms of that setup yet when i run 'test run' i get ACPI BIOS errors.. i try halting the windows boot and plug in the HDMI end into the EGPU to try " hot plug" and windows loads up yet the "microsoft display adapter" does not appear in display(device manager).

This laptop is such a good laptop and would be perfect for my setup.. Really begging for your expertise guys
Thank youuuuu!!!
 
Solution
Some laptops just don't like egpus. The wifi card slot is not meant to support a egpu, meaning that it probably was not designed for it nor was it ever validated for such use.
