Recommended Posts

System

Lenovo G40-70 (This may work with these other Lenovo laptops which share the platform:  G40-30, G40-45, G40-70m, Z40-70, Z40-75, G40-80)

CPU: Intel Core i7-4510U, 2.6 GHz

iGPU: Intel HD Graphics 4400, 1024 Mb 

RAM: 8 Gb DDR3

OS: Windows 10 x64

 

Setup

eGPU Board: Bplus PE4C v4.1 with M.2 Key A/E (http://www.mfactors.com/pe4c-v4-1-pci-express-16x-card-to-m-2-card-or-pcie-x4-connecter/  Model: PE4C-M2060A)

Video Card: MSI Radeon R5450, 1024 Mb GDDR5

Power: Antec 430W

External Monitor: Asus VE228

 

Tools Used

DIY eGPU (https://www.techinferno.com/index.php?/files/file/87-diy-e-gpu-setup-130-by-Tech Inferno Fan/)

HWiNFO64 (https://www.hwinfo.com/download.php)

Phillips Screwdriver

Dremel

Heat Gun

Sugru

Packing Tape

 

The Build

To run DIY eGPU, Windows has to be installed in a non-UEFI boot mode.  Here are my current BIOS settings:

jv6qWdEbEzIqY4Smrr9R7ANT0k7yr70j6eghCVql

 

519DG21YeeEBTx4JRNvvSYY1YGXRhbsZRnRt_FUw

 

Once Windows was re-installed, I installed WiNFO64.  Here's what the hardware looked like prior to installing the PE4C in place of the wireless card:

slhNIYZ520KmVXyTo8ox48NDcBdY-33iXT6JnTml

 

Then I installed DIY eGPU by right-clicking on setup-disk-image.bat and running as Admin:

vRb3z1f1bGO3ZIJ_PrJzmg3gDAtkPrBtjjZ7R0uY

 

Rebooting and selecting DIY eGPU Setup 1.30:

6fwkMx0xHKLQ0gPqitJ7X3Bie02_JKv8CarwU0yB

 

Then "menu-based":

8MqPkOx9bBym7fTb-3VvBahnqqGR-2hzl6UeVrHN

 

There's the Atheros wireless card in the DIY eGPU hardware list:

wccHlN4Q65LKrvASYmWs-ZMnGXlYP0oAsVQL1B3O

 

Shutting down I then removing the wireless card:

TcOb0kyoVofRbvGUqSQnQXbM6-LX1YoWSpowD5iz

 

I then used a Ryobi dremel clone to slice off a portion of the laptop's plastic case and chamfer the edge off of the CD drive connector.  This was necessary to get the cable to fit into the PCIe slot and tuck the cable up so that the laptop is able to sit level on a desk.

I also cut a notch into the removable cover on the bottom of the laptop:

8hEnkiam3N3nzxQYnYvq-4FCt18VqPct9x6fjfZN

 

I used a heat gun to soften the hot glue inside of the heat shrink on the plug, so that I could slightly bend it to fit:  (Note: That is a cat hair, not a manky man hair.)

A blob of Sugru:

gM6xBEeh7awRapHJO-IA84JDieC4yVd6EGKKiZw2

 

And some masking tape keep the cable secure, while letting me remove it relatively easily:

gmBybg1DFAOj5pAZnAlgP8C6tHJClA5eDGv2YRg8

 

I plugged my MSI video card into the PE4C, kept the Delay and Settings switches at their stock positions, turned on the ATX power supply and booted the laptop into DIY eGPU.  And there's the video card listed in the hardware where the wireless card used to be:

npvU3sExk6Hj-M_xzR9WD_dYa_iHXNjpI5hEGo-l

 

Then i ran PCI Compaction:

Ukv0l-14T1sb8czhV1pr6TYhTf6WlJ77O59dzChK

aidb94SsX2pL8uefWl9BYw-dpD3F2awl-P4NxQb2

HmMeBabhysDYtMLg1pLDeGUZX8usaXkyWQJv7ULh

 

I was unable to return to the DIY eGPU menu:

OlIQIrpRbdIc5E5YN48uED-d_7wAUISTbLSfPhNH

 

So I just rebooted into Windows and ran WiNFO64 to check that the external video card was detected:

l-gpZqveYA8D8wk1Ao31NGikPdT5p5SgOy4VspI0

 

Then I installed the latest Radeon drivers, & connected up my second monitor.  I now have dual display with the second monitor set as my Primary and the laptop's display below it as the Secondary.

 

UjGl31QUtcmUwvVXCIyydaAtJLxB8FyGc3vtBgSc

 

Quality-wise I've been able to run games that my laptop alone couldn't handle, such as the We Happy Few alpha.  The low-end frame rate isn't great, but with some overclocking using MSI Afterburner it's doing pretty well.  As the card is sitting out in the open it doesn't overheat.  I'm not sure if this matters or not but I ran.. or at least tried to run.. three different benchmark apps:  3D Mark Demo (wouldn't run), MSI Kombuster 2 (also wouldn't run) and Heaven benchmark.

 

Stock

FPS: 14.0
Score: 352
Min FPS: 5.7
Max FPS: 25.3

 

Very Basic Overclock

FPS: 13.8

Score: 347
Min FPS: 10.4
Max FPS: 24.6
 

Next steps might include a different power supply, so I can put the ATX I'm currently using back into the 3d printer, and perhaps a case for the PE4C & video card.  Maybe someday a better video card.

 

I hope this has been helpful for someone.  Please ask me questions if you have any.

 

Note:  This is my second PE4C, as the first one I purchased would not work no matter what I tried.  They eventually RMA'd it and I bought a second one which worked out of the box, first try. \o/

Just a follow up post...

 

A friend sold me his 2nd hand EVGA GeForce GTX 970.  Initially I had a lot of trouble installing the new card.. mostly because my dual boot to Ubuntu was messing with my video display, making it impossible to boot into DIY eGPU.  Once I had that sorted, I removed the old drivers, installed the new.  But no joy.

 

I could see the new vid card in DIY eGPU and in HWiNFO6, but Windows would only boot up using the onboard video hardware.

 

After much fooling around with various settings, reboots, etc.  I opened Hardware Manager to make sure the card was appearing there.  I noticed that it wasn't enabled.  So of course I enabled it and BOOM everything worked!

 

Maybe this info will help someone else.

Did you change you hard disk to mbr from gpt?

 

I deleted all partitions and did a completely fresh install of Windows.  (I'm not certain it was even  necessary.)

I don't know, I've never tried.  But an EGPU setup will plug into your wifi card slot and make it impossible to plug in a different wifi card.

      Hi folks,
        Greetings from Brazil!  Not sure I'm posting in the right place, but I have a question:  how do I find out the brand and model of my BIOS chip without having to open my laptop?  I can't find this information anywhere.  Been searching for days... I have a Lenovo Ideapad 300-15ISK 80RS (motherboard Paris 5A8).  Thanks a lot for your time and help! I really appreciate it!   Best regards,   JC.

      Hi, I'm having problems trying to connect a GTX 750 Ti to my Lenovo T420 using the dock EXP GDC Beast (express card version).
      My laptop: Lenovo T420
      RAM: 8GB DDR3
      CPU: Intel Core i5 2520M
      GPU: Intel HD Graphics 3000
       
      My problem is: if I plug the express card and I turn on the laptop it doesn't boot up and the screen becomes horrible, with coloured pixels and a sound like "bip-bip".
      If I try plugging the express card when the laptop is already turned on it sees the gpu, but if try installing the drivers I have to apply the modifies restarting the computer.
      I hope you understood my problem (I don't speak English very well).
      Please help me, It's making me crazy!
       
      EDIT: I didn't say that if I plug the express card when the pc is already turned on, in the device menager there is "Error 12" on the gtx 750 ti

      In this thread you can post your requests for Lenovo Y50-70, Lenovo Y70-70, Lenovo Z50-70, Lenovo Z70-70, Lenovo G50-70, Lenovo G70-70.
      If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, or unlocked vbios for overclock NVIDIA card, then you can post your request in this thread. Also, if you have a problem with fan pulsating/clicking on any modified bios then you can post your request in this thread.
       
      The flashing procedure include two steps:
      1.  Flash main system bios.
      2.  Flash EC firmware.

      When my first CPU fan on Y500 is broke i replaced it on something compatible (non-original) and planned to replace it later on original. Since that time happened a lot things, but i still using that non-original fan. But i did some research and here is what i founded:
       
      I. ORIGINALS
       
      1. Forcecon (marked as FCN on fan)
      DFS5413005MH0T-FC1C (5V - 0.5A)
      Spotted in: Y400, Y500.

       
      2. Asia Vital Components (marked as AVC on fan)
      BNTA0612R5H-P007 (5V - 0.5A)
      Spotted in: Y410p, Y500, Y510p.

       
      3. Sunon (marked as SUNON MagLev on fan)
      MG60120V1-C230-S99 (5V - 2.25W (0.45A))
      Spotted in: Y410p, Y500.

      So, which to choose? Any recomendation? Maybe there also unexpected way (completely diffirent fan from another company for another laptop)?
