I bougth the same adapter cri-cri bought and I can confirm, that it works at Gen 2 speed.

Now I would like to try to desolder it and put a cable in between. I want to move my mpcie slot to a position where it is easier to access. Any suggestions on wich cable to use?

i talk about kz-B26 not kz-B22

I don't think this one will work either. Hwtools writes on its page: Maximum speed of PCIe2.0 (5Gbps) is not guaranteed.

In my opinion the problem will be the extra connection and the unshielded cable.

I tried it and still get code 12. Im starting to think maybe its a problem with win8. In the devicemanager my egpu is listet as PCI-Bus 2.

Tech Inferno Fan edit>> mrbauer's problem was solved via PM.

I've actually not been hotplugging it while Windows is in sleep mode. My Method is to have the eGPU off, boot up the machine, boot into Setup 1.x, then power on the eGPU.

Thanks daver 160. This was the point i was missing. Now setup 1.x detects the egpu almost everytime. But not always.

Have you tested to make sure that Windows detects your eGPU?

Power on your laptop, then power on and plug in your eGPU, and boot into Windows normally. Your Device Manager should detect your eGPU so that you have 3 display adapters. Your eGPU GTX 660 should be recognised by have an Error 12, which is a good sign.

This works perfectly.

Don't forget to make sure that your "10de:11c0" is in fact the one listed in the Setup 1.x screen. For example, when you boot up into Setup 1.x, it will detect your iGPU, dGPU, and eGPU. Make sure that you are using the address ID that Setup 1.x sees for your eGPU otherwise it'll be looking for something that's just not there!

The startup.bat you posted works for me and 10de:11c0 is exactly as listed in Setup 1.x.

I altered call chainload mbr to call grub4dos mbr.

It works both ways, but with the chainload one I get an errormessage.

If I run the startup.bat and chainload to win, the dgpu is disabled, but I still get code 12. I think this is related to the pci compression. I tried several options. With some it works, but there is always the code 12. I hope you can help me out here.

I got 8 gig of ram and even if I change it to 4 gig it doesnt work.

I hope you, daver160 or Tech Inferno Fan could help me out here.

I finally got all components for my egpu setup. My setup differs a bit from daver160s. I got the same laptop, but with the i7 2820qm and Windows 8, the PE4l adaptor, for Pci 2.0 support and a GTX 660 as egpu.

I set it up today, but I couldnt get it to work.

1. Preparing the machine for eGPU this worked, after some trying.

2. Installing and setting up eGPU components it basically worked too, but if I boot up my notebook with the egpu powered up and plugged in. It doesn't start. I just got a black screen. It just works if I plug in the egpu in sleep mode.

3. Running Setup 1.x Didn't work at all. I had the same problem like daver160. It just freezes if I try to disable the dgpu. So I tried to switch out the startup.bat and then I did not now how to go on.

My startup.bat now looks like this:

setpci -s 1:0.0 COMMAND=0:7 10.l=0,0,0,0,0,0 -s 0:1.0 b0.w=10:10 19.b=0,0 3E.w=0:8 COMMAND=0:7 20.l=0,0call iportbus force

call iport g2 1

call vidwait 60 10de:11c0

call vidinit -d 10de:11c0

call pci

call chainload mbr

Maybe daver160 you could provide a step by step guide how you did it.

Thanks for your help.

I think Im going to test one of this adapters. It would be great if they go on 2.0 speed. And it would be even possible to desolder the half slot and solder a cable in between. So that you have an extension or could place the slot at another place in your notebook.

Hey.

Great work. I have almost the same laptop and Im going to do a egpu setup with a gtx 660. But I dont understand exactly what would happen if I dont use setup 1.x. to disable the dgpu. Would it work at all? And is it maybe possible to disable the dgpu via bios?

Hey guys I have PCI-E 2.0 x1 port #2 and i plan to buy KZ-B26 and PE4L for easy plug and unplug can it work properly

Thanks in advance

This wont work at 2.0 speed. As dicussed in this topic: http://forum.techinferno.com/diy-e-gpu-projects/2958-pe4l-pm060a-mini-pcie-extender-2.html. I wanted to build somethin like that on my own.

Im about to get started on my own egpu. I already ordered a pe4l 2.1 and a gtx 660. I have a dell Xps 15 l502, with a gt540m dgpu.

As I understand it I definitly need setup 1.x to get it to work. But what would happen if I tried it without setup 1.x. Would it not work at all or would I just miss optimus?

Hello,

1x is the best you can get with an EC2 Slot. So you best go with [email protected] and try to enable optimus, since you have a GTX 670.

X2 and higher are only possible with more than one ECSlot or mpie slot or a combination of both. And I think they wont work at 2.0 speed.

Hey,

@Hunter20 I dont think these will work. And even if they work they will take a lot of space, just consider you need 18 or 19 pins. I peronally like the idea of cri-cri much more. In fact im thinking of trying something like this on my own.
