anyone upgraded to Windows 10?

and if yes, does the DYI work? (dsdt is ok?)

Just upgraded to Win10 this morning. Still trying to get my DSDT override to work, if I use asl to override it hangs at boot. I installed uefi by accident so DIY eGPU setup doesn't work :(

Hi i have been running an egpu setup for months now and have only recently began having trouble with the update to windows 10. Before the upgrade i was running a copy of Windows 7 Pro 64 bit this worked fine as i did a dsdt override and was able to get my egpu running with a boot through setup 1.3. However with windows 10 im still sure i need the DSDT override so i have tried it countless times and cannot get it to generate the Large memory section. I have also tried multiple configurations with setup 1.3 to boot up with my egpu and cannot get it working. Any help is appreciated.

Errors i am getting range from the computer picking up the device as a default video adapter to Code 12 when it reads it right.

My setup:

HP Elitebook 8440P (upgraded to Windows 10 Pro 64 from 7 Pro 64)

8 GB Ram

Core i5 540M (with integrated Intel HD graphics)

250 Gb HDD

Egpu:

The Beast EXP GDC 16x PCIe adapter (connects via expresscard)

GPU im using in it is the Zotac GT740 2gb.

well here are my steps:

- i used the "bcdedit -set TESTSIGNING ON" cmd (not sure if it is needed though, it was for wind8)

- follow this video

for easy steps for the override

- to get the .aml table, use the -f option with the "iasl" cmd

I'm not sure at which part you're stucked but I'll try to help :)

Okay thank you sooo much i will give this a try and get back to you. I had it going for 7 so easy i didnt think updating to 10 would be an issue.

EDIT: Okay i am lost with this video and the links are either broken or to files that are non existent. Did you need to download what he did in the video?

Got windows 10 fixed and had egpu working in some sort of test mode. I only switched out of that when my games could not (or would not) launch do to Driver signature check verification being disabled. Im not really sure how i enabled test mode but it displayed a version : Build 10240 in the bottom right.

And coyote im going to give the DSDT override another shot. Will be posting my results, seeya.

Hello,

My question is - how do I forbid Optimus turning off dGPU or disable Optimus at all (I have no graphics options in BIOS)?

Yesterday I upgraded to Windows 10 and installed Nvidia Driver for Windows 10. Everything seems to be the same as on Windows 7, both dGPU and eGPU (and ofcurse iGPU) are showing up in Device Manager and no hardware problems are present. But, when I try to set dGPU as PhysX processor - it does not let me, when I try to set dGPU as PhysX processor it switches back to eGPU automatically.

I think the cause of the problem is that on Windows 7 I had Optimus disabled. But on Windows 10 I have Optimus enabled and I did not find a way to disable it to rule Optimus as possible cause of the problem.

I can confirm that dGPU is only briefly turning on when it is being accessed (like when I want to see info in MSI Afterburner, or when I want to see driver details, or when I scan for new hardware) and then powering off after 2-3 seconds.

Hello there!

First of all, thank you for this great forum. After is stumbled upon this forum i wanted to try an egpu setup myself.

I shouldnt of done that :P

My rig:

Deviltech laptop

i7 720qm

5870m, 8gb, win 7

I bought a beast egpu and fitted an 7850 (from my desktop) on there. Fired it up. In device manager it shows its there!

And there it holds. Its there, but i cant do anything with it. According to amd program its a secundaire gpu, but its disabled. I cant get it enabled!

When i just swith the 5870m (internal) off i get a blank screen. After reboot it says there is no amd gpu installed (device manager says otherwise)

GPU-Z says it there. When both cards are switched on i see all details in gpu-z (bandwith etc etc) when i switch off the 5870m (internal) it still shows the 7850 (egpu) but no details.

Question: Can i run the 7850 on internal lcd?

Or do i have to buy an nvidia card?

Regards Dennis

Hey,

If you have a quick look in the pros and cons at the beginning of this thread I think you might find the answer to your question. I'm pretty sure you have to do a little trick to get AMD cards to run on the internal LCD.

Unfortunately I'm new here and don't have enough experience to tell you what your enabling problem might be. But here's the link that's given in the pros and cons to do with the LCD.

Maybe the PSU has less power that it says and it's more important quality than power. Here you can read some guys whom have problems until the change the psu.

Give it a try ;)

Hey, I tried with a 750w and everything worked flawless, thanks for the advice!

Cheers for the reply! This forum is crammed with usefull information. My prob is i cant get the question in a right search format :P

Ive gotten myself a gtx 465 from the scratch chest... Seems to be working (didnt expect that). Think this will be easier to get on internal lcd :)

hi @Tech Inferno Fan i already have use eGPU with my gtx 970 but ignore the setup 1.30 but i saw this setup can make more performance with x4. While i want to use x4 it only port 1 and port 5 but both failed, how can i switch my eGPU is port 2x2.0 or 4x2.0

Port 1 and 8 is empty and port 3,7 is disable

If you have electrical links to support x2 (port1+2, port3+4, port5+6 or port7+8) or x4 (port1+2+3+4, port5+6+7+8), then need to unlock the flash descriptor and modify the bios using the FITC utility as described at http://forum.techinferno.com/dell-latitude-vostro-precision/9690-14-dell-latitude-e6430-performance-upgrades-system-mods-2.html#post130202. Only then can the port run at x2 or x4 speed.

Hello all,

I just recently managed to set up my GTX 670 as an eGPU, so thats good news :D .

Here's a quick look at whats going on.

post-37462-1449500062689_thumb.jpg

eGPU set-up:

Dock : EXP GDC Beast (mini PCI-e)

GPU : Asus 2GB GTX 670

Power supply : Dell DA-2 220W

Monitor : 32" Sony TV

System:

15" Acer V3-571G

Processor : i5-3230m 3.2 GHz Dual

RAM : 8GB Vengeance

Integrated GPU: HD4000

Dedicated GPU: GeForce 710m

OS : Windows 8.1

Graphics driver : 353.62

@Tech Inferno Fan

I'm having some real issues with performance. My card is recognised, the monitor is running fine, there are no errors in device manager and the card is clearly doing work because it heats up. However, my 3dmark11 score is in the low 6000s and 3dmark doesn't recognise it as a 670. Performance in game is also terrible. I've been looking through @kizwan 's thread and cant find anything related. The only thing wrong is a black screen on boot, which a reboot solves. Please help. Thanks in advance.

EDIT : From what I've read eGPU setup 1.3 MIGHT solve my problem but I have an SSD so I have no partition type. Is this a problem? Is there a way to get it running without eGPU 1.3?

@Woosypan

from the screenshot you posted, 3Dmark ran the test on the 820m not the 670....although it's a 710m you have?

Optimus should kick in and disable the dedicated gpu, and the egpu should take place.

I don't understand how this works really (i don't have a dGPU) but my guess is that you'll need a dsdt override and/or the setup 1.3.

Hi,

i have a problem with my egpu an i hope someone can help me with it.

I have a lenovo x230t with an nvidia gtx 670. I conecctet them with a PE4L V2.1 with Expresscard and an 550Watt beQuiet power supply.

This config runs without any problems for about a year. Here and there some restarts and hotplugs if it doesent start at once but it worked 99% of the time.

But since a few weeks it doesn't work anymore. If i plug in the epxresscard before i start the laptop, between the boot and windows or with windows already running: the cpu usage get extremly high, Service Host: Local system (network restricted) and System Interrupts, eat the most usage and also windows stutters extremly, the mice pauses it movement every 1-2 seconds and so on. I tried a lot to solve this but nothing helped: i set up a clean windows installation a few times with just the needed drivers installed, i reduced the RAM from 8gb to 4gb, checked the gpu in another computer where it worked without any problems and also deletet the iGPU drivers.

When it worked the sequence was to start the egpu, plug it in, start the laptop than, if it worked, the laptop turned off automatically but in 3-4 seconds turned on again and it worked.

Now when he turns off automatically it seems that he is in some kind of endless loop and the display remains dark. This or the previous mentioned stutters. Also the Laptop doesn't recognize the eGPU in the device manager only the iGPU is visible.

If someone has an idea what I can do to get it working I would be very grateful.

What have you been playing? Some games are very sensitive to small bandwidth of the graphics card. However, your 3DMark11 score should be fine. The review by Futuremark states 9550 points for the GTX 670 which is most probably reached with a quadcore CPU. Also you're losing performance by the small bandwidth. You've only got 1/16th of the bandwidth that a graphics card with x16 PCIe 2.0 has, always keep that in mind. Your mobile "only" dual core is also decreasing the physics score which is then decreasing the whole score.

Check if you've got actual x1.2 connection or only x1.1 with GPU-Z under load. You can use Furmark for this or GPU-Z itself, there's a button on the main window that pops up a small graphics application that puts your card under load.

A 820M would never reach anything near this score. Futuremark states 1210 points for this card.

I've been playing some CS:GO, and with decent settings it doesn't run above 100 constantly (which it should do no problem) and full settings are jumpy (other setting can be jumpy too). I haven't played any other games really but the bench marks were seriously low fps, not one was above 60 and the physics was max 12 fps (I know this comes down to my CPU a lot).

The problem I have with it all is that if you look at the other implementations of my GPU the lowest 3dmarks are in the 7000s and someone running a very similar laptop to me got it over 9000. I think my processor might actually be a little better than his too.

I understand the bandwidth issue and I'm trying to find out if I'm 1.1 or 1.2 but I can't see it in gpu-z. My question is, how can I improve the whole situation? There is setup 1.3 and there's Verde mod drivers that I can see, but what's best for me?

Look at "Bus interface" like in this picture:

Is your TOLUD ok? Forget about any Verde or whatever drivers. You only need the usual Nvidia desktop drivers.
