Hello again everyone,

Since I had the issues with my setup I kind of gave up. The performance was solid but weirdly jumpy meaning I couldnt play games well. I have recently plugged everything back in and tried to get it going again using my internal LCD and it simply wont work. I get the following error: 'You are not currently using a display attached to an NVIDIA GPU'. I have clean installed my drivers and had a look at the internal LCD section along with the dGPU section in the guide thread. As far as I can see none of it relates to my problem, besides maybe getting Setup 1.30 and doing something technical.

Any help would be appreciated,

Woosypan

Additionally, although I can understand your situation, posting the same stuff in different threads won't magically let a solution fall from the sky. The DIY experiences thread is usually well visited so if you haven't got a solution presented it may be because it's difficult to find.

Totally understand, only reason I posted it here was because I once I saw this thread I thought it might have been in the wrong place before. Thanks for the help.

Hi guys,

Sorry to be a burden. My eGPU is not performing as well as it should. Boots fine, shows up fine in device manager. Even runs games fine. Just not as well as it should.

There is sometimes some juddering from what I can only assume is a pci-e bandwidth issue and the card benchmarks lower than it should, showing a loss in performance. So far we have discovered that I am running PCI-E x1 2.0 and that my TOLUD is good enough. I have disabled my dGPU (and now my iGPU) in device manager along with HD sound from the card to try to free up resources for the eGPU and it hasn't helped considerably. Here are some screen shots about my system that may help.

Thanks in advance for any help,

Woosypan

Laptop Specs:

Lenovo Z710

Intel i7-4710MQ 2.5GHz

8GB Ram

1TB HDD

Nvidia 840M

Windows 10

Egpu Specs:

PE4C-PM060A V3.0

Nvidia GTX560Ti

Now the issue I have, I can get all the GPU's to show up fine in device manager and If i play a game it will use the 840M, However I cant change what card I use as it wont allow me to load the Nvidia control panel. Here is a screenshot of my GPUz and device manager.

Is there something I'm missing here? I have wiped all the drivers and made sure there was nothing left on the system and used to latest DESKTOP drivers with no luck. Any ideas?

Are you running an external monitor? Have you tried right clicking on the 840m and disabling it?

P.S. Pretty sure its not a driver issue as your system is showing it in device manager as the right card. If you have done a clean install of your drivers, that pretty much eliminates it any driver issues

Hi Everyone, I have Lenovo Y50. I want tou use external GPU such as Geforce 970/980/980TI. Is my notebook compatible to use external gpu?

my notebook has wireless lan card atheros AR956x. i do not know what kind of m2 or NGFF. please suggest devices that i need to use external gpu?

thanks.

It depends on whether or not your lan card uses PCI-E or not (which I might assume it does). But nevertheless do some digging on what port your wireless card uses. The only versions of eGPUs I know of are express card or PCI-E. The EXP GDC Beast has models for both, but there are other companies that do different solutions. Do some research and see whats best for you.

Your TOLUD is more than ok. It's the last PCI Express Root Complex entry on your first screenshot.

"Currently running at PCI-Express x1 2.0" is also what you want although your GPU-Z screenshot shows x1 1.1 but I guess you hadn't put load on your GPU at that moment. If you press on the "?" button to the right of the bus interface section you get a little popup window which shows graphical stuff. At bus interface there should then stand x1 2.0 instead of x1 1.1, you might test this.

Apart from this I'd also say the problem is due to the PCIe connection either because the x1 2.0 is not stable or your adapter is faulty. You'd need Setup 1.x to force a x1 1.1 connection instead of 2.0. I had a Haswell Asus notebook and I simply couldn't get it to work with x1 2.0 connection and the x1 1.1 that I got to work was way too sloppy.

Ok, first of all, thank you so much for all the help. Secondly, under load it runs at PCI-Express x1 2.0 (I'm guessing good news). Also, how do I get my hands on setup 1.x or 1.3?Not sure if I mentioned before that it takes 2 boots to get the system running, the first boot just shows a black screen, is this important? Finally, I'm trying to get the dock replaced because it came with a slight dent in the PCI slot, so if that comes about we can rule out faulty adapters.

Besides all that, where the jumpy image is my main concern. I still have concerns that it isn't running at its full potential for some reason. I understand it wont run nearly as well as it would in a PC, but why are people getting much higher benchmarks than me with the same card if my TOLUD and PCI-E port are the correct spec?

Look at "Bus interface" like in this picture:

[ATTACH=CONFIG]15714[/ATTACH]

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

Right so I've had a look at both things and I cant find any specific examples of device managers looking like mine. So here's some screenshots I took.

So I have no idea what my TOLUD is or if there's anything I can do about it. Also, when I hover over the bus interface it says 'currently running at : PCI-Express x1 v2.0'. To be honest the frame rate on max settings is actually staying above 100 at the moment, not sure it would for long. But the picture can be stuttery or jumpy at times which is a big problem and this is down to the pci-e port isn't it? I guessing both these things I have shown are bad, but is there a way to deal with the jumpy issue and improve performance?

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?

Hello all,

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

Here's a quick look at whats going on.

eGPU set-up:

Dock : EXP GDC Beast (mini PCI-e)

GPU : Asus 2GB GTX 670

Power supply : Dell DA-2 220W

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?

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

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.

Pls do some background reading beginning with existing eGPU implementations a reference: http://forum.techinferno.com/diy-e-gpu-projects/6578-implementations-hub-tb-ec-mpcie.html#dx11

There we see that your system had an eGPU successfully attached already:

http://forum.techinferno.com/implementation-guides-pc/9742-15-acer-571g-gtx570%404gbps-c-mpcie2-exp-gdc-beast-win7-64-%5Babdullah%5D.html#post130965

This is amazing information and I cannot commend you enough for your help. Those experiences can tell me that it will indeed work and what power supply I can use. However two questions remain that are fairly simple and I believe I know the answers, but I cannot be sure. I will leave what I think are the answers in brackets after the questions.

-Will it work even though I already have a dedicated chip (710m)? (I assume yes on this one)

-What external dock do I need? (not looking for an enclosure, I don't have that sort of money)

-What power supply will be needed for the GTX 670?

-Can I buy a power supply that can power an entire desktop just for the GTX 670, just in case I build a desktop in the future?

(yes, the gpu will only draw what it needs from the power supply and it wont cook the gpu)

-Do I definitely need a second display or is there a way to use my laptop screen?

(no, an external gpu needs to be plugged directly into another display and there is no way to use the HDMI output on the laptop as an input)

Thanks again,

Hi guys, I am very new to all this so here goes.

I have an Acer V3-571G:

i5-3230m

710m 2gb VRAM

8GB 1600mHz Ram

I have recently come by a GTX 670 and am planning to run it externally. I'm pretty damn sure I only have one PCI-E slot where the wifi card sits, but taking that out isn't a problem. I have many questions, so I will list them off as bullet points:

-Will it work even though I already have a dedicated chip (710m)? (I assume yes on this one)

-What external dock do I need? (not looking for an enclosure, I don't have that sort of money)

-What power supply will be needed for the GTX 670?

-Can I buy a power supply that can power an entire desktop just for the GTX 670, just in case I build a desktop in the future?

-Do I definitely need a second display or is there a way to use my laptop screen?

The post that led me to this thread was on neowin and part of it read; 'IMPORTANT - Make sure to read the thread to establish what speed graphics bus you will have access to on your laptop and what features will be supported by your combination of laptop/graphics/PE4L.'. I need to understand this statement better and what it means for my machine.

I'm sure there are questions that I've missed out but we'll just see how we go with this so far. I'm sorry for being such a scrub.

Thanks in advance,

Woosypan
