Acer V3-571 + R9 270X x1 2.0 mPCIe eGPU implementation writeup...

Sure, tell me if I miss something.

Notebook model: Acer V3-571 series

CPU: Intel Core i5 3210M

iGPU: Intel 4000 only, no nVidia iGPU inside.

eGPU kit: PE4H V2.4 mPCIe + PCIEMM-060A and B

VGA: Club3D Radeon R9 270X

Power supply: Scythe 500W

Setting up

With the PCIEMM-060A cable, I was unable to run @2.0, as soon the VGA needs to process something more heavy a BSOD pops out. But there was no major problems running @1.0 except for performance loss or some unstable FPS on some games.

The setup 1.x process was:

Got the VGA ID;

Force linkspeed to Gen 1 on eGPU(VGA) port;

Run PCI Compactation and choose the first 36-bit option avaliable. And chose to apply only on eGPU;

- 32-bit options somethimes get stuck on a black screen before the chainload starts.

startup.bat

call speedup lbacache

call iport gen1 2

call vidwait 60 [VGA ID]

call pci

:end

call chainload mbr

Using the PCIEMM-060B cable I only changed to force Gen 2 on the eGPU port, no changes on other options.
