I recently successfully got my egpu working (topic is mentioned in this thread somewhere)

I have one question. I bought a dell adapter for power ( model adp-220ab b )

and I am looking for an extension for it but I cant see any 8 pin to 8 pin that match the design, did dell design it in such a way it cant be extended?

Can someone make any suggestions?

Ive solved my problems and all my solving and discoveries are here.

I plug my eGPU after windows has started now. Because whenever I run it while already plugged in I get that screen.

Also I used a GTX750TI like you before as well but my laptop didn't have enough resources so I used the GTX660 from my desktop which was fine.

I could use the GTX750TI as well but I couldnt get Nando's DIY egpu Compaction feature to work

This is my contribution to this forum. My procedure and setup that worked.

Hardware used;

L@pt0p; HP 2570p Elitebook

GPU; Geforce GTX 750 Ti

PSU; NEX650G

Boaard; PE4C 3.0

Connection; ExpressCard/34

Can someone recommend me something to replace the NEX650 PSU?

I wanted something like this https://www.amazon.com/Dell-OptiPlex-D220P-01-ADP-220AB-ZVC220HD12S1/dp/B00CFGVWXG (Dell 220W DA-2 AC Power Supply Adapter)

Im trying to make my physical appearance not be as... big.. so I can make a nice enclosure

[[[Remove this if not appropriate]]]

My goal was a simple plug and play eGPU solution to play Darksouls 3 with my girlfriend

Finally got it to plug and play and just work.

Hardware;

HP 2570p Elitebook i7, 8Gb RAM

GTX660 (Originally GTX750TI does not work with HP 2570p easily)

            Possible to use GTX670/760/770 due to similar resource requirements in comparison to GTX750TI

PE4C v3 EC/34

750W PSU (Unnecessary output)

Windows 7 ( Windows 10 = Error 12 = More work)

Started out with a GTX750TI Which was a mistake because I should of bought a GTX660, luckily for me my desktop had one already and all I had to do was swap.

You can make a successful eGPU from a GTX750TI however it requires alot more work unless you have a laptop that has enough TOLUD range to accommodate it. My experience with the 750 was a painful.

I personally would only pursue it if you are more educated in this type of field.

I have been unplugging and reattaching and it seems to just work great, Im reinstalling Windows 10 to try that

Steps

1. Waited for Windows to start loading then,
2. Plugged my rigged GTX660 + PE4C to my EC/34 slot,
3. Upon loading it appears in my device manager, not named GTX660,
4. Downloaded the GTX660 driver from NVIDIA and it recognized the GPU,
5. After installation it will name the GTX660 in device manager.
6. Requests restart, I had to pull it out after hitting the restart button and then quickly replug at windows load
7. It didn't work immediately,  after unplugging/replugging while laptop was on it started to give a display to my GPU's HDMI output which was connected to a monitor.
8. I played Darksouls 3 and it works great.

Safely Remove eGPU

1. Shutdown laptop
2. Unplug once off (Ive gotten a blue screen once prematurely pulling for some reason)

SPECIAL THANKS to Nando and Arbystrider, I would of gotten no where without you guys.

Please correct me in anything because I want to know this abit more intimately.

I also dont mind admins editing, moving or altering the content or the title etc if needed

DSDT override process that you'll need to host your gtx750ti is at the following URL. If cant nut this out then consider getting a gtx660/670/760/770 all of which have a smaller pcie aperture that can fit within the 2570p's bios set TOLUD limit.

 

Thanks for getting back to me Nando. I had looked at an article stating that  gtx660/670/760/77's fit better but already have my device. Im also using windows 10 and considering dual booting windows 7

Will read this thread and see how we go. Might make a video

Hello,

I am a big fan of the eGPU idea and started a first try, back in 2011 with a HP Elitebook 2540p i7. It was fantasic to see, how a business notebook can get gaming performance only with a small circuit board and a midrange desktop GPU. (PE4H v2.4 with a Geforce 560ti EVGA). I had a lot of fun with this system. But I haven ‘t high competence in software or hardware things. Basic Knowledge I would say.

etc etc etc

 

Did you get any further?

I managed to get the gpu detected and driver installed etc but and error 12 occured (not enough resources)

Im using 2570p with GTX750Ti linked by EC34 via PE4C v3

Windows 10

Ran nandos and couldnt seem to toggle certain functions perhaps because Im running legacy instead of UEFI

Let me know what you are up to

sold gtx 750 buy  lesser contiguous s 128MB+64MB  graphic card  GTX670/680/760/770.. they use 128MB+32MB of space.

Im trying to use a GTX750TI on my HP 2570p. Is it not possible? Would you recommend selling for a 32bitish kinda card?

I had no idea I could be limited in this way before buying the card

Ive tried for awhile and now I think I need private help. Willing to paypal

Error 12 question.

bump me or message me privately if you can help I think its simple now, hopefully.

hp 2570p, gtx750ti, pe4c v3 ec/34, nando 1.3.

Hi aldimeola81,

Thanks for the response. Turns out the GPU was totally DOA as I suspected. I took it to work (haha) and stuck it a desktop--still didn't work at all. Returned the GPU, was sent a new one, it worked fine right away (well after an hour of playing with pci compaction--iGPU+eGPU with eGPU forced to 32 bit is the only thing working). I was so happy to see that error 12, such an improvement over getting not even a spin of the fan. Also, thanks to nando who helped me to realize that the card was simply DOA.

" I have now also tried a PE4C, with all combinations of sw1 sw2 switch settings. So I have now tried two adaptors. "

Where can I find out about these SW1 and SW2 things? I cant find any explanation anywhere

Hardware used;

L@pt0p; HP 2570p Elitebook

GPU; Geforce GTX 750 Ti

PSU; NEX650G

Boaard; PE4C 3.0

Connection; ExpressCard/34

Software used;

OS; Windows 10

BIOS; Legacy (Has option for Hybrid and Native UEFI, tried native didn't boot)

Progress so far, issues noted under each figure, please help.

When turning on the gpu before the laptop the screen stays black and my external monitor connected to the gpu by hdmi doesn't seem to work at all.

I plugged the gpu after turning the laptop on and I got the following results in fig1 and 2. GPU detected but after installing driver it asks me to restart which makes it come to a black screen. I am using a hdmi output from my gpu.

I dont think it completeed its driver installation upon restart

Figure 1. Setup. The 24pin ATX from PSU has a lid on it which allows for the gpu+psu to run I can hear the fans. Not connected directly to the PE4C (displayed above)

Figure 2. GPU is detected in device manager, but when I run the nvidia driver it says not compatible or not found etc.

Figure 3. Not sure about my BIOS at all. But when I run in Native UEFi windows never loads, automated shutdown.

Figure4. In properties of the gtx750ti it says not enough resources, how to rectify this problem?

Error 12? Im reading this 

Whats the function of the SW1 and SW2 switches?

• Support two delay switch to avoid registration problems when boot. (SW1, SW2)

Also cant do anymore till my laptop arrives, dont want to blow up my brother laptop

I do believe that the 24-pin ATX connector is meant to go on the PE4C.

I have attached the 24pin ATX connector directly to the PE4C and now both fans from the gpu and psu dont run.

Seems to only run when I have the 24pin ATX seperate with a "tester" cap on it, like in the picture.

The only power that is connected is a 6/2 pin to the gpu which is connected directly to the PE4C and a VGA ATX 6/2 to the PE4C power slot lower left, also like in picture. 

Is it possible to accidently not connect enough of the power slots and still get it to respond this way? 

Hey guys. So I got this far.

Connected the laptop HP EliteBook 8460p i5 2450M to this ASUS Geforce GTX 750 Ti 2GB GPU via an express card /34

And this resulted in my laptops display not initialising which was to be expected I recall reading on different threads here.

My second monitor is using hdmi so I tried hdmi on the gpu and also connected a hdmi to dvi adaptor to the laptop and sadly the monitor never detected anything,

Can anyone help make sense of this with me?

BTW I connected the egpu while the laptop was off. Then powered the laptop on

I do apologize for making no sense. I had the goal of just making the fans run.

I've looked online for abit and I cant find a way to access my PCi-e section on my Samsung RC520 . Does every laptop have one?

I have successfully run the fans by connecting the pcie 6 pin into the gpu and connecting the gpu to the riser with a pcie 4 pin connection. But for what ever reason I had to connect the MB pcie 24pin with a "testing cap" on the end. ( Displayed in picture)

Also can you recommend an alternative to my riser? Ive noticed alot of you use   EXP GDC v8.0  or something similar. Is it not possible with my one?

Some cables and attachments with my riser

EVGA SuperNOVA G1 Gold 650W Power Supply
ASUS GeForce GTX 750 Ti OC 2GB

PCI-express 1x to 16x 16x-1x mining Extender Riser Card + Power + USB3.0 cable 

Samsung RC520 15.6 inch Laptop (Intel Core i5 2410M 2.3GHz, 6Gb, 750Gb, DVD SuperMulti DL, WLAN, BT, Webcam, Windows 7 Home Premium 64-bit) - Black/Silver

These are the parts I plan to use. I dont have a laptop with working usb3 unfortunately so right now my goal is to just get the fans to run on the devices which I dont seem to have any success with so far.

I have plugged the VGA 6/6+2 cable from the psu to the gpu and no fans seem to operate.

Any solutions for connecting it to a laptop without usb3?

ALso any recommendation on new reasonably priced laptops? I need something lighter for uni
