@diyman, your CUDA-Z results are a little below what's expected for 4Gbps-EC2. This likely means there is may be bit errors requiring some error correction being performed down the link.

FIX: Add shielding parallel ground lines to the PCIe TX/RX wires

There is one way you can improve this. The 4 PCIe TX/RX lines PETn0/PETp0/PERn0/PERp0 mPCIe pins 23,25,31,33 have noise shielding ground lines running parallel to them. In your implementation you have been connected these lines to a common ground as central silver blob.

So simply wire them in parallel so the differential signalling provides electromagentic noise suppression. If all goes well, your CUDA-Z H2D numbers will then be as expected.

You're right. I will improve later.
I wanted to reduce the number of solders because the pins are very small.  😀
I now test a GTX 560, but unfortunately the card is unstable (cooked card). If I find a card that is stable, I will edit my build guide with new CUDA-Z screenshots.

Thanks for help!

Could you draw where to solder which cable, because I didn't understand, I should be able to test what you draw by the end of April, when my adapter arrives

All right, I will attach a drawing, into the implementation guide.

Thanks, since I don't want to mess up my expresscard adapter when arrives

can you please draw a sketch where to solder mpci to expresscard. photos are ok...but dont help much.

thank you

I got my expresscard usb 3.0 today, could you help me with this, i need a draw or some documents to learn which ping goes where

I added the drawing, I hope to help you with the project
I wanted to do a better drawing, but I did not have enough time.
Later I might update the drawing and publish newer results with GTX 560.

I look forward to feedback.  🙂

Thank you for the drawing. One PCIe TX/RX GND shield wire location was corrected & opening post drawing updated. Please be sure to use this as a reference if doing further updates.

I added changelog.

thanks for the drawing...

hey all,
sorry for asking this in your thread: my adapter cards look alittle bit different.
which one should i use?
https://ibb.co/mPsPz7
No1 and No2 - are they the same? can i use them both for egpu? -or both not?
my usb to mini usb adapter dont have the WAKE# to bridge. does this matter?

thanks for your help!

@j_chaina , can you please link me where you purchased adapter 1? That one has a USB 3.0 connector on the PCIe and mPCIe adapters. As there are flat USB 3.0 cables it gives greater underside threading in tight spots capacity than adapter 2 that has a mini-USB end.

oh sorry my picture is misleading: i got two risers from amazon:
No1
https://tinyurl.com/y9ejwytr

No2
https://tinyurl.com/y7or4fg6

...and i also got this adapter on ebay:
https://tinyurl.com/y85curuj
(i dont know if i can use this adapter for my modding?!)

(both risers work so far that the GPU is running on it with a 430w psu; but my thinkpad t430 wont reconize the egpu through minipci - tried it all; with gdc beast v8.0 expresscard it works all fine, but only with gen1 - this is why i want to mod to express card like in this thread) - i will post my complete build guide later.

Oh I see. This adapter wires the USB lines to the USB cable. As PCIe wires required for an eGPU are not being wired through, it does not make a good adapter candidate for modding.

..but i can use No2 for modding?
thanks for the fast replies!  🙂

Yes. @diyman mods No2 in the opening post.

Your mpcie adapter with green PCB, only a mPCI-e to USB adater.
With this can you plug a wireless mouse recevier into this usb socket.
This use a circuit to make 5V from 3.3V.
The adapter with blue PCB has mini-B USB, but with custom wiring for x16 to x1 risers.

The green is not good for the mod, only the blue.  😐 

I have a plan with usb Type-C connecting, but it's need a lot of soldering...  🙂

thanks for the fast reply-
yea i also thought so..the green is only for normal usb stuff!

The blue one doesnt have the WAKE bridge. like yours. so i dont need to solder bottom mpci-e pin2 to WAKE pin on the express card?

i like soldering  😉

The wake pin is optional, this can the pcie device awake from sleep.

Maybe I will add my Type-C plan with draws.

@diyman, I believe an even simpler mod could be made here that would :

(1) use a male-ended USB 3.0 interconnect cable
(2) maintain the integrity of the USB 3.0 expresscard - just either end would be disconnected from the original circuitry

Could do that by:

1.allocate one of the USB 3.0 jacks on the expresscard to be for eGPU use
2. etch into the USB 3.0 circuit board (USB 3.0 port end) just beyond the 9-pin USB 3.0 jack pins to disconnect it
3. etch into the USB 3.0 circuit board (expresscard connector end) to also disconnect it from the circuit
4. Do some investigation on how to wire those 9pins USB 3.0 pins to the expresscard pins
5. Solder in the wires as needed being sure to run GND shields around the four PCIe RX/TX wires

I did not want to Type-A usb to use for connector on the laptop, because my family is also using my laptop and so could plug in either a pendrive physically to the egpu port. And this would not be good...

ok guyz... I cut off the board on the expresscard.. and I was facing serious problem...
how the hell I am going to solder that small things together...I am not a person who gives up easily...but that is insane... I might entirely give up and try another expresscard solution

I will give it another go and try my best to solder it together...

while searching for the options, do you think @diyman this adapter would work?

I see 9600 I press like. Great modelling too.
Good stuff!

Would you like to do an external mPCI-e slot?   

This PCB factory of the express card?
If so, then there is no need to solder well.

This is a pure solution for a mPCI-e slot with hotplug.

If it works, it's a very good idea!  🙂

I think this is like yours:

@jaggiemccool, I do not see tracks leading to the PCIe TX/RX pins 23,25,31,33. Your adapter does have USB pins 36, 38 wired suggesting it's an expresscard-to-USB adapter only.

There is an expresscard-to-mPCIe adapter but it's not so readily available, nor is it cost effective:

Same here, I give up, I don't have enough skill to do this, is there any adapter?

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

Hello, first time posting here so sorry if i don't know something!

I found out some riser cards for miners pretty cheaply from store. I would like to know could i use it like i would use EXP GDC Beast?!
Here is some pictures of the riser and connections: (I would use ExpressCard USB 3.0 adapter to connect USB to riser card)

So these are the main things i need, of course GPU is needed too and PSU too 🙂
I would like to know will this work in my 8470p?

@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?

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

I added GTX 560 results and V2 solutions - May 18, 2108

@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.
