DIY eGPU experiences

[LoneNF]

I've got a question:

Let's say I don't want to connect my eGPU via ExpressCard. Can I use a different Adapter instead, like a mini HDMI to Displayport or mini HDMI to HDMI?

What are you going to connect your eGPU to?
At the moment there are 3 possibilities:
-- ExpressCard:
-either the ExpressCard 1.0, than you use the PE4L v1.5 or PE4H, than you connect the HDMI cable to the ExpressCard-EC2C
-or ExpressCard 2.0, than the HDMI cable is soldiered to the EC2C

-- mPCIe: you connect the HDMI cable to the PM3N, that is sticked in one of the mPCIe slots in the insides of your laptop

Some people modify their laptops (soldering and usually cutting of the laptop required), so the HDMI port replaces some native port of the laptop, or some cover is removed to connect the cable inside of the laptop

-- you have a Thunderbolt port and connect some eGPU device though that port.

I would like to know whether you can connect an eGPU via Displayport or HDMI, instead of the possibilities you named. After all, that's how the ExpressCard Version is connected to the GPU. Just that the mini HDMI Cable is conncted to the Laptop via the ExpressCard Adapter.

No, you can`t.
There are some devices that use USB3.0, but they are not suitable for eGPU yet.

The eGPU is not connected to the HDMI port, the HDMI cable is used to connect the eGPU and the expresscard (the PCIe interface). The Displayport or HDMI ports are connected to the graphic card of the laptop, not the PCIe interface.

The HDMI cable is used only because it suits the purpose well. You could take many USB cables, or any other cable, that can carry the signal from the expresscard to the eGPU properly. There are even no HDMI connectors in the PE4L v2.1 because they are causing to much distortion of the signal. So the HDMI cable is simply a good cable and doesn`t has anything to do with actually HDMI interface.

The goal of the eGPU is to connect the desktop graphic card to the PCIe interface of the laptop. It is possible, as i wrote, through expresscard, mPCIe card or thunderbolt port.

GER:
Der HDMI Kabel wurde nur genommen, weil er bequem ist für diese Anwendung. Nicht weil man eGPU durch HDMI Ausgang anschließen kann.

Thanks, understood it now.

My native Language is actually english, but here in Germany you hardly ever get to talk english, which is why I might sound a bit "rusty".

Hello,

I've discovered this forum recently. I find it very interesting and I'd like to give this eGPU solution a chance:-)
But I got one problem. Before I buy the PCIe-expressCard Adapter I want to be absolutely sure that my laptop "supports" eGPU.
So the question is:
Do I really need to pay $25 for this test?!
First nando4's article in the beginning of the thread says:

...
To be absolutely sure an eGPU can be accomodated requires booting Setup 1.x and performing an 32-bit PCI "All" compaction...

But somewhere else I read that Setup 1.x costs $25.
Since I haven't found any 8540p's results yet I'm a bit confused.
So is there some cheaper way to check my notebook? Or I just somehow overlooked the download link?

Thank you very much.

PS: HP EliteBook 8540p with dGPU NVS 5100M (1GB), 8GB RAM installed and TOLUD seems to be 3 GB.

I haven't posted in a while and I've come up with an interesting finding. If you're getting microstuttering, which sometimes happens with optimus, you can get rid of it by setting an FPS cap. In diablo 3 with the fps cap off, around 1/3 of the time I had microstuttering, which at times was horrendous. My computer would go back and forth between 180fps and 18 fps. I set the fps cap to my refresh rate (vsync alone did not work) and the microstutter was gone. Note that there is still some microstutter, but lots of people complain about it, so it seems to be something to do with the game engine.

Diablo 3 is the only game I got microstuttering in with opt x1.2. On 1.1 I also got microstuttering in SWTOR, and other games may also microstutter. You can globally enable the FPS cap using EVGA precision on any Nvidia card as long as you have a 300 series driver installed....

I have experienced this especially with Diablo 3 and have found the same FPS cap to help. I will test the FPS cap on the only other game I ever play on my laptop: an emulated ps2 game. However, it does not have anywhere near the amount of microstuttering as in D3, so that game might not yield any useful information.

I have had the same problem with Diablo III, but in my case I disabled the shadows and the problem was almost gone. I will try the FPS cap to look what happens.

In my case I have a Lenovo T420 + Geforce GTX 550 TI + x1.2 Opt.

Your English is completely OK, i simply saw Germany as your location. My mother language is Russian, but i know English good and German very good So i wrote a note in German

Setup 1.x is not a program to check the possibility of using eGPU. It`s made to overcome problems that rise during the connecting and setup of the eGPU.
But the idea with the check is interesting

Dudes,
I paid 25$ for the eGPU setup. So how will it be delivered to me?

[smflesh]

Is this possible with the Acer Aspire 5741G? Has anyone tried it with this model?

It doesn't have an expresscard slot but I'm not too sure about the mPCIe / whatever else can be used
