DIY eGPU experiences

kizwan,
OK, thank you! I'll write more when I have everything to eGPU

[kizwan]

Good luck!

Should the V2 of PE4L perform better than the normal? I thought the V1 was pcie2.0 capeable?

I had a quick question. So I'm waiting for my x3 mPCIe cards to do my x4 setup. I was able to get my x1 working with no errors, so should I foresee any problems getting the rest going if x1 is working fine? Can't wait to get it all setup.

I was also curious but when i had my x1 HD4850 going flash was giving my errors in Firefox and Chrome. I'm using the latest DNA driver. When I went back to my iGPU it was working fine.

Good luck!

I have bad news. I learned that the Intel Turbo Memory (ITM) has a different pinout, which does not coincide with the mini-PCIe pinout (mPCIe port #2 is used for ITM and TV-tuner).
I inserted the Wi-Fi adapter in the slot for ITM (mPCIe port #2), and Wi-Fi card is burned!
But ITM normally works in mini-PCIe slot for Wi-Fi (mPCIe port #4). I think that the Acer 5920G is not possible to get a x2 link. I think it is necessary to remove such information from the first post.
This explains the failure of user antichamp (link)

Can I get the link to where you got the information that ITM have different pinout? As far as I know it is mPCIe card & connect to mPCIe port. I can't find any info to suggest otherwise. Also 5920G schematic show it's PCIe lane. antichamp's post didn't mention it have the same problem, only unable to get x2 working. According to antichamp's previous post, connecting WIFI to PCIe port#2 doesn't caused any problem, in fact WIFI is detected. Also, the picture show that PCIe port#2 & port#4 doesn't show up if no device connected to them. This means using the mPCIe port for eGPU will be tricky. Setup 1.x anti-whitelist should be able to make eGPU to work with mPCIe port on this notebook.

BTW, ExpressCard is PCIe port#1 based on the information here & here.

I can not give a link because it was found out during our correspondence in Russian Acer-fans forum, it's all written in Russian. I have wi-fi card is detected, but after 5-7 minutes the laptop was freezed and no longer start with Wi-Fi card. Without it - normally starts.
I will check the mPCIe port #2 when I get PE4H... But I think it will feil

[kizwan]

Using eGPU with mPCIe port on your notebook will be a bit tricky (I edited my previous post ^^) but Setup 1.x should be able to get it to work.

Ok, you reassured me
I will try ...

If you put back the Intel Turbo Memory to PCIe port#2, does it detected in AIDA64? Also, if you put back WIFI card to PCIe port#4, does it work again? If Intel Turbo Memory is not detected anymore, I'm afraid PCIe port#2 is burned.
