DIY eGPU experiences

[kizwan]

Ok, now the newer version works, but it hangs too. Always at the same time when the setup says:

--More--(85)--
command:compact@arg.fil equiv of [*compact pciend 100000000 devcon.txt
ignore 8086:0116 makebatch R:\config\pci.bat*]
Copy R:\config\pci.bat(ram dsk)-> A:\config\pci.bat(drv)...
command=call pci.bat Performing PCI write (compact@Sat Nov 12 8:59:01 2011)
Press [Enter] to return to menu...

When I press Enter it hangs. I run the 32-Bit Compaction with this settings:
Ignore:GPU 1 or 2 (No matter whether 1 or 2, when I choose "Ignore:None" then the Programm always says:"No solution found", but when I ignore 1 or 2 the programm always hangs)

I can't help you on that. You can run "Save diags" in Setup 1.x & post it here. Nando4 can take a look for you. Everything you need to know how to get the dump file after running "Safe diags" are available in Setup 1.x page.

Other solutions

1. Can your notebook boot with eGPU already connected to notebook? If you can, BIOS might be able to allocate resources for your eGPU & this will solved Error 12 you got.
2. Did you use D.N.A. drivers? It also can solved Error 12 in certain conditions.

Thank you!
I think I can use the PCIe port #1 & #2, that's what I see in everest:

But what kind of videcard is better for me to buy? Should I use a gtx 560 or may be better to use the Radeon?

Look like you can do x2 link. The ExpressCard slot is most probably PCIe port #1 & the other empty mPCIe port is PCIe port#2. I don't have any recommendation for you. Any ATiAMD & Nvidia graphic card will do. Look like you're leaning toward Nvidia graphic card. Either GTX460 or GTX560Ti are suitable for you. If you want to get GTX560 (without Ti), I think better you get GTX460.

Ok. What about 2Gb of video memory? It would be better to x2-link or it does not matter?
Now I choose between GTX560 2Gb and GTX560 Ti 1Gb (same price)

[kizwan]

As far as I know, the video memory doesn't play major role in performance. Better get GTX560Ti.

No, it can´t.

Did you use D.N.A. drivers? It also can solved Error 12 in certain conditions.

No, I used the original Driver, but I will try this out, thank you.

You can run "Save diags" in Setup 1.x & post it here.

I will do this, thank you again.

After installation of the newest D.N.A. driver my system don´t says:"Code 12", but it says this now:

Die digitale Signatur der für dieses Gerät erforderlichen Treiber kann nicht überprüft werden. Bei einer vor Kurzem durchgeführten Änderung an Hardware oder Software wurde möglicherweise eine Datei installiert, die falsch signiert oder beschädigt ist. Möglicherweise handelt es sich auch um schädliche Software einer unbekannten Quelle. (Code 52)

In English:

The digital signature of the necessary drivers for this device can not be verified. In a survey conducted recently, changes to hardware or software may have been installed a file that is signed incorrectly or damaged. There might also be malicious software from an unknown source. (Code 52)

Uninstall the D.N.A. driver then reboot. Before windows loading, press F8 to bring up windows boot menu. Choose "Disable Driver Signature Enforcement". Then install D.N.A. driver again.

It still says "Code 52", even after the Re-Installation. I will remove the DNA driver an install the original driver. Then I will post the Save diags here.

Ok, Windows is crashed after I make the Save diags. It wont boot up. I am writting this from Ubuntu.

Windows is okay now after I deleted the eGPU files from Linux.
