After a few days of properly working egpu I got an error 12(could not allocate resources for graphic card).This is a startup.bat setup that I was using so far:
call iport dGPU off

call vidwait 60 
call vidinit -d %eGPU% 
call pci
:end 
call chainload mbr  
 

  . Operation- Run compaction works fine in DIY egpu setup 1.3. I tried to follow those those instructions:

 

So I managed to modificate startup.bat like that:

 

call iport dGPU off
call iport gen2 2
call vidwait 60 
call vidinit -d %eGPU% 
call iport reset 2
call iport init 2
call pci
setpci -s d:0.0 BASE_ADDRESS_5=d001
setpci -s 0:1c.1 1c.b=d0 1d.b=d0
:end 
call chainload mbr

 

It also did not help. Here is my pci.bat file: 

pci.rar

I would like to buy a graphic card to use as egpu.I am going to connect GPU to my laptop HP dv6-6173sf via mPCI-e . My question is:  which graphic card  would be better, Geforce GTX 970 or Radeon RX 480 to have as egpu and which egpu adapter would be better PE4C-PM060A V3.0 or exp gdc beast?
