Hey guys,

At last I got my eGPU to work:haha:

Since there is no guide on how to set up a double width full length graphics card with the native 10Gbps Sonnet Echo SE Thunderbolt to PCIe adaptor, I want to write down how it worked for me. Thank you Nando for supporting me. It was a bit of work to get me up and running

My hardware configuration

Steps to get it working

1. You need to cut the gpu from power supply through the adaptor and reconnect it to the PSU. This is needed because the Sonnet Echo SE comes without a PCI Reset Delay. Done by following the wiring guide created by MystPhysX (here).

2. Wire everything up.

3. Install Windows 7/8 via Bootcamp

4. Boot with PSU/eGPU powered OFF

5. Install DIY eGPU Setup 1.30, run c:\eGPU\egpu-setup-mount to get drive v:\ and use notepad to create the two text files in the spoiler:

v:\config\startup.bat

 

call speedup lbacache

:: wait for eGPU to appear on the PCI BUS
call vidwait 60

:: initialize NVidia eGPU
call vidinit -d %eGPU%

:: Perform the pci-e fixups
call pci

:: Chainload to the MBR
call chainload mbr

:: Speed up end-to-end runtime of startup.bat using caching

 

v:\config\pci.bat

@echo off echo Performing PCI allocation for 2012 13" MBPr based off Tech Inferno Fan's findings . . . :: The X16 root port @echo -s 0:1.1 1c.w=6030 20.l=AE90A090 24.l=CDF1AEA1 > setpci.arg :: Underlying Bridges in order from high to low @echo -s 4:0.0 1c.w=5131 20.l=AB00A090 24.l=C9F1B801 >> setpci.arg @echo -s 5:3.0 1c.w=4131 20.l=A700A200 24.l=C5F1B801 >> setpci.arg @echo -s 7:0.0 04.w=7 1c.w=3131 20.l=A300A200 24.l=C1F1B801 28.l=0 30.w=0 3c.b=10 >> setpci.arg @echo -s 8:3.0 04.w=7 1c.w=3131 20.l=A300A200 24.l=C1F1B801 28.l=0 30.w=0 3c.b=10 >> setpci.arg :: The NVidia eGPU @echo -s 9:0.0 04.w=400 0C.b=20 24.w=3F81 10.l=A2000000 14.l=B8000000 1C.l=C0000000 3C.b=10 50.b=1 88.w=140 >> setpci.arg setpci @setpci.arg set pci_written=yes

 

6. Boot with eGPU powered off

7. Your eGPU should work:Banane38: You can install any game you like and enjoy!

And some stats from my experience:

Battlefield 3 Ultra graphics settings and Full HD --> 40 fps

new Neverwinter MMO on all graphics settings maxed --> 35-40 fps

Metro last light on maximum settings --> runs fluently (didnt check the fps but it looks nice)
