(EXP GDC Beast v8.4d mPCI-E + GTX970 + ATX PSU) eGPU project for Lenovo IdeaPad Z710, i7-4700MQ, 16GB RAM, SSD, GeForce GT745M

Recommended Posts

Hi,

I want to show you my new project.

I bought my laptop about 5 years ago.  It was never speed deamon, but for every day use, it was enough to me.

 

Its specification:

Intel i7-4700MQ

Nvidia GeForce GT745M

16GB RAM

512 SSD Adata SU800

Yesterday I bought Witcher 3. Of course on 1080p it's impossible to play, because of about 10fps :D

 

So I make a decision to buy external grahpic card.

I choose GTX970 and now I am looking for occasion to buy it.

 

I've already bought EXP GDC v8.4d mPCI-E. It is used and cost about 30$.

I will use ATX PSU to supply graphic card, because I have old desktop PSU at home.

 

My plan:

1) unlock bios

2) buy GTX 970

3) enjoy Witcher 3!

 

BTW I try to cool down my laptop, so I replaced thermal paste to Kryonout Thermal Grizzly and make some tests. Temperatures and fps are on screenshots.

 

1) laptop on table, playing GTA V 1080p

- first minute (GPU core 1045MHz)

-after some time, because of high temperature and GPU throlttling (GPU core drop down even to 400MHz)

2) with thermalpad Glacier NC400 SilentiumPC

- 30 minute and longer (GPU core drop to about 900MHz)

 

3) without down case of laptop (like on picture with thermal paste) on thermalpad.

Here laptop never drops down MHz and max temp are about 72 Celsius degrees.

Bacause of that I bought second down case for my laptop and I will cut there additional holes.

 

Greetings!

 

I will describe next step when I get all stuff I need!

Nice, if you are going to cut some holes or modify the backplate you could maybe fit something like a low profile cooler like the SlimHero 56mm tal (136W TDP) or maybe the Noctua NH-L9 37mm tal (65W TDP). That would probably fix all throlttling issues and allow you to run a bit higher clocks also if you can mod the socket to fit.

      Hello, A couple of days ago I got a new GPU but when I installed it into my computer I was unable to use it but now I know why. When checking the device manger I went into the events tab of my GPU when I went to view all events, I noticed an error it said " event 411 kernel PnP " and It also said Problem Status: 0xC01E0438. I believe this is why my GPU hasn't been working on my PC. If you know how to fix this problem or have info on how to fix this problem that would be greatly appreciated. I'm also using a EVGA NVIDIA GeForce GTX 1660.

      I'm having a problem where my PC is saying my eGPU is not usable, its detected in the Device Manager and it doesn't have the yellow triangle next to it. I cant use it games and the Nvidia Control Panel doesn't recognize it either. I'm using a EVGA NVIDIA Geforce GTX 1660. I'm using windows 10 and I tried DDU and reinstalling them and now I cant access the nvidia control panel. The GPU is not recognize on any other apps and I went on *********** and was unable to find my answer, Any help on how to fix this problem would be greatly appreciated.

      Title sums it up.
       
      TL;DR: we have a Clevo that runs a desktop CPU, one with those huge 82 Wh batteries. We remove the GPU and let it use the CPU's integrated graphics. How much time for the battery to go from 100 to 0? Is it comparable to an ultrabook's?
       
      I'm theorizing a mobile set with a static eGPU and an upgradable CPU. Given a hypothetical user that needs fast processing on the go and long battery life while retaining very high degrees of mobility, but at home wants a powerful machine to run most games, I guess that would be their best bet. It would surely be more convenient to keep everything in the same disk. And even though the thing would be quite heavy to carry around, changing CPU would be more cost-efficient than changing an entire laptop. (Not sure if I'm right here, and also I'm not sure whether the motherboard in a Clevo would be replaceable when the new CPU needs a different socket, which is another reason why I'm asking here.)
       
      If my above guesses aren't correct, then an ultrabook with Thunderbolt and without a dedicated GPU would be a better choice. If they are, then we would be carrying more weight in exchange of a more cost-efficient setup, which I think would be a fair tradeoff.
       
      Also I am aware of the heating problems that these laptops suffer from, at least compared to a desktop setup. Would they be solved by moving the GPU out of the chassis, and instead plugging it with an eGPU dock via Thunderbolt port?
       
      What do you think? Is it doable? If not, why?

      Hello!
       
      I have a notebook Asus X550CC.
      Some weeks ago my screen went black with the brightness working though (black screen but one can see brightness changes) - I couldn't figure out the root of the problem, since it was sudden and it works with an external monitor.
      Now, I was trying to install an SSD with a caddy. I went to BIOS to change the boot order, but couldn't find my SSD - so, I accidently disabled launch CSM option hoping it would recognize it or something. After that I couldn't access BIOS anymore and I have a very slow startup with dxgkrnl.sys, wdfilter.sys and CAD.sys showing not loaded in the boot log.
      I tried to:
      Remove CMOS battery for 8h  Short JRST2001 and JRST2002  Access BIOS through windows 10 troubleshooting None of the above worked for me
      The laptop does not restart or shuts down correctly as it gets stuck somewhere and I have to press ON/OFF button again in order to shut it completly. The only display I can see in the external monitor, during start-up is the windows 10 loading screen (can't see the asus loading screen) and it takes more than 5 minutes to get me there (seems like a bootloop).
       
      I hope someone may have the answer cause I'm running out of solutions 
       
      Thanks in advance, everyone!

      Hello everyone
      I created a case for egpu using 2.5mm acrylic sheets. The first time I created a case to support a GPU + ATX psu
      Now I created another one for the GPU with an external Xbox 360 203w psu.
      the finish was not good but for my use it is already good.
       
      *both cases album
      *Construction of the second case 
      *adapting xbox psu to 8pin power (taken from 24pin)
       
      all made by hand with the tools I had.

      from Brazil.
