and how do i do that?.. sorry if it's something really obvious, but i have no idea.

just put the card under load,and look in the gpu-z for the pci-e link,must be gen.2 according to your setup

gen2 bandwith gives a real experience on the internal screen...

Also, do you buy chance also use the EXP GDC adapter? If so, is the "ATX PW" switch in the left or right position?

Edit: moved the switch into the left position, things seem to be fine. Now the eGPU and the PSU turn on and off when I turn the laptop on and off. Previous freeze seems to be game-specific. Aside from some stuttering, games are stable to run. Will try connecting to a TV via HDMI to see if stuttering/framerate improves.

ok.look if the pcie link is working on x1.2

I am using pe4h v2.4 wich i had try in various notebook,not gen2 compliance,although remember once achieved in a msi with an i7 Sandy bridge to reach gen2 bandwith.

yeah, the problem for now is that the nvidia control panel is impossible to open. i'll try the WIN8.1 drivers tomorrow and post the results when i do. Thanks for the advice, since my laptop initially came with 8.1 on board it is worth a try.

ok.

it will work finally,that is my guess..

you will not see two display in the optimus internal screen,only you wil have a transparent option in the nvidia control panel wich alows to use egpu as a preferred render graphics

ok.

let me know the news.

Start thinking that  your dgpu interfiere in some way in the optiumus function,i am quite sure that you will have acceleration in an external monitor but the internal display function it is disabled.

Here's the Device manager, showing the active display adapters and on the second screenshot, the pci-e bus part that I disabled

ok.it is how it should be.....

are you familiarized with upgrading BIOS procedure ?could unnhide the option to disable the dgpu within your bios .

Not recommended if you not have experience with this .....

and don´t give up....it is not an option,keep trying drivers and search for documentation in this fórum...i can guarantee that it will work

sorry,screenshots...

windows has a tool that make just that,search "screenshot"in the search box of cortana...

Please make a snapshot of your display manager list and device system list.

Tried the latest drivers just now, and nvidia control panel gives the "no monitors connected to an nvidia gpu" message. Will try the older version now.

 

Update: Older drivers such as 372.70 result in the exact same message appearing. Starting to think about getting a monitor...

Currently running Windows 10 64-bit.

Try the latest see what hapenning,then try any driver before  372.70 .I am sure you will get the internal screen functionality one way or another. i will take a look inside your bios see what options you have.

I am unaware of optimus functionality lately regarding the drivers,try the last one and let me know please.Also i want to know wich operating system are you running.

Hi,now that you left only the igpu and the egpu,download the driver for the gtx960 from the nvidia website,the last one.let it untouched.

try to install it an let me know what is hapenning.

The 740m need to be eradicated from the displays manager list,you have to see only the igpu and the egpu there.

There is two ways to do that,disable in bios or use x1setup provided by ******.

Sincé none of them is available for you you coud try to disable the pcie that host the gt740m,not the card but the pcie bus that host it in the system device.

Works for me few times. i see you are mod the driver,guess there is no need for that,once you achieved that the system not see the dgpu,you could install the egpu  driver without mod.anything.

ok.

Hi,have you disable the dedicated card?

Optimus is not working with the gt740m in the device manager list.

Hi Mugsat! the best method to do DSDToverride for me is to use DsdtEditor ,found here:http://olarila.com/forum/viewtopic.php?f=7&t=62nts

Easy and clean extraction of the dsdt.aml,used by me in windows 7,8,10 never failed.

Previous you have to install java in order to work properly.then you have to install asl compiler version 4.0 for windows 7 and version 5.0 for windows 10.

Hello techno guys. Im just a new member here. I would like to know if theres a solution with my diy egpu problem. I have a lenovo b490 i5 2.6ghz, 8gb ram dgpu nvidia 610m, exp gdc beast 8.3 via mpcie, gtx 750 ti, 600w atx psu, connected to external monitor. Everything works fine but the problem is, when im booting it up from set up 1.30 i always disconnect my external monitor and reconnect it after booting and logging in to windows, because when i dont, the loading screen and logo of lenovo will just hang and will not boot to the os and set up 1.30. If any of you guys have the same situation, can you share to me your solution, Im just afraid my vga connector will wear out in my orthodox process together with my egpu card.

hi,you have to have a delay switch on the exp gdc beast board,try to adjust the time in sec from when the bios detect the external gpu.Good luck!

it work... thanks man ...  

hi,sparrowsp

could you upload some benchmark along with an gpu-z snapshot (wonder if gen 2 pci-e signal is stable on this laptop along with the beast adapter).I  am looking to upgrade my notebook and could one as yours be an valid option for me, also looking a thinkpad x230.

Thank you!

Anyone can help me please?

 

specs:

Hp elitebook 2570p

windows 7 64 bit

My problem ... is when i plug in with gt 730 64 bit it work perfectly....... but when i plug gtx 750 128bit and gt9500 128 bit ....

i get error 12 code............. it occur when i plug any 128 bit gpu... :'(

Any solution guys?

hi,think the gtx750ti need more space.try dsdt override fist,if not solved use setup.x1 in order to do a succesfull compactation against gtx750ti.

Thanks for the response, Dan! That's what I figured. I just wanted to make sure that I did some troubleshooting before shelling out more cash. I'll keep everyone posted on my progress.

Edit: Stupid question: would a DSDT override even work even if the device manager doesn't even detect it at all? I get all the lights, fans, and usb ports going, my TOLUD is 3GB, is it still relevant?

Just to double-check:

Possible problem children?

Edit 2: ^Forgot to mention that Port 3 is where I put my egpu in (expresscard). I guess I need an override after all?

dsdt override create a 36 bits space in the memory map wich is needed in some cases when the tolud is high to open the posibility for setup 1.3 to make succesful compactation in that space too if all intents in the 32bit failed and the posibility to use more ram in some system with high tolud.dsdt override may not be enough to detect your egpu without a succesfull compactation .
