@dub_monster , you query has been moved into this thread showing how to make a DIY expresscard adapter for use with the PCE164P-N03 PCIe riser.

Alright, thanks. So can i just plug that USB cable to that Expresscard USB adapter, without soldering mPCIE board to it?

hi... @diyman i did not have much time lately, but what if I could put your solder drawing into a bit precise scheme and contact a shop which makes custom flex boards... something similar like photo below

flex connection

or perhaps more cheaper solution to use these stripes and glue for pcb...
flex stripe wires

I do not think this is worth it.
I think the drawing is understandable. I added serial number and the name of the pins for clarity.
If you can produce PCBs, that would be the best solution.

Please note that my message is always reply to quoted message.

These ingredients are appropriate.

First, do not cut the PCB.
This ExpressCard already has a USB socket PCB and should be physical stability.
The printed wires must cut off the surface of the PCB. For example, with a blade.

If this is the case then you need to know the USB socket pin on the PCI-e.

You need to be sure of the pin assignment.
You can do this with a multimeter.

In my situation, the following is:

pin1 - WAKE
pin2 - REFCLK +
pin3 - REFCLK-
pin4 - PERST

pin5 - PERp0
pin6 - PERn0
pin7 - GND
pin8 - PETp0
pin9 - PETn0

USB 3.0 pinout

@diyman, thank you for the updated.

Did you CUDA-Z host-to-device numbers improve with the V2 solution indicative of better signalling?

This is an important thread as these older expresscards systems, while having a convenient eGPU attachment point, no longer have a cost effective eGPU adapter to attach to them. The lowest cost EXP GDC Beast has shown voltage & signal instablility.

This $7 eGPU adapter + $5 USB 3.0 expresscard + USB 3.0 cable + 9-13 soldered wires to attach the USB 3.0 pins to the expresscard pins looks to be the most cost effective solution & simplest modding solution. Just require someone to show it being done.

Unfortunately, I did not have the opportunity to test the re-soldered ExpressCard with the old USB cable.

I thought the 60cm cable was wrong because the eGPU did not work.
It turns out that 3.33V is dead on the riser. Now get 3.33V from the ATX PSU directly.
But I've cut the cable for directly soldering.
That's why I bought a new 1m long cable, but this does not go to Gen2 unfortunately.
With V2, I mean the new card and new case.

Now I bought a new riser (with included cable) on ebay, and I hope that only the 1m cable is of poor quality.

Ok, so i need to solder some things... not so easy as i thought

Hello,
I can also confirm, that you can use an ordinary gpu mining riser for egpu setup. I bought mine for 5$ locally and I got a USB 2.0 Expresscard adapter for free - very cheap setup 😀 . I've made a lot of shorts while trying to solder the wires, so I've designed own pcb using EasyEDA and let it manufactured (it was my first experience with doing that). Then i soldered wires to new pcb and riser's PCIe 1x connector easily.

My specs:
Lenovo T430 - i7 3612qm, Nvidia NVS 5400m
GTX 660 Ti
I got the eGPU running OK

It works pretty well GPU-Z shows PCIe 1x 1.1 and 2.0 connection from time to time. But CUDA-Z shows 370 MiB/s H2D speeds, thats not bad.

While browsing this thread I got an idea of redesigning the pcb and connecting the Expresscard and USB directly on pcb. Than you can desolder the EC and the slim USB 3.0 connector from the USB 3.0 adapter.

I wonder what is the real life difference, between your card 660ti and OP's 9600gt...  because both cards seem to work on pcie 1.1  about 300-400MiB one way... I am thinking what is the card limit for this line speed, I mean which card is already out of the this range (pcie 1.1 -2.0), but maybe that would be a question for @nando4

or perhaps how would the gpu perform in games vs. video editting (if used 560ti for example)

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
