Hi all

I am about to purchase the needed things for an DIY eGPU but first I have a few things I would like to ask.

I have the following laptops: Thinkpad T61, T500 and T410 all with integrated graphics. I am guessing my best bet would be to use the eGPU with the T410 due to it has an I7 cpu. However It would be great if I could also use it on my T500, would that be possible?

I have been looking at the PE4L v2.1b and PE4H v2.4a and I am really not sure which one I should by? The PE4H is around 30 USD more expensive than the PE4L.

Your help is much appreciated!

 

You should buy PE4L 2.1b for PCI 2.0 performance. I iam using T420 with PE4L 2.1b and GTX560 card. It is quite smooth to launch GTX560 as main graphics card and i got 3dmark06 benchmark 16997. It will wise if you buy a Thinkpad with i7 and without Nvidia NVS dGPU graphics card. cost will be reduce and not need to disable dGPU from bios.

 

Great thanks for the help.

My Thinkpad T410 is with integrated graphics already, but thinking about getting a T440 so might just settle with Integrated for that one aswell.

 

then what you will do with T410?? please through it to me

 

My intention was to buy a PE4L v2.1b + a GTX 560 TI and somekind of PSU.

 

Heyo,

Just stopping by to say that I successfully eGPU'd w/ PE4L & GTX560 Ti on my T420. Finished my little enclosure a few hours ago, I love it Overall spent on the whole project, in case any of you were considering:

PE4L + ship from Taiwan = $80
MSI GTX560 Ti 1GB = $90
DIY Enclosure = $15

All in all 'twas under $200, and if you get a cheaper GPU/better deal that number can go down even more.

Had some issues with drivers at first [and performance is still not where I hope it to be], and I haven't sorted out a way to boot w/o using non-external, but all is well and I can play the vidya.

 

So, I`m struggling.

Bought the PE4H a while back and finally got around to doing some testing. Benchmarked the machine before I tried this and got around 5500 in 3dmark06. So I bought a GTX 660 and did the following:

1. Booted into Windows
2. Hotplug the GTX 660, install the drivers using the driver disk that came with it.
3. Reboot

I only get a 3dmark06 score of 6200. Any idea why this is so low?

 

did you totally shutdown internal gpu??

 

1. You need disable the discrete GPU if you have any in the BIOS not device manager.
2. Make sure you are running external screen through the external graphic card.
3. Use 3dmark11 to bench DX11 for ur 660.
4. Also make sure your power supply is on before your system.

 

Can someone please help me, Im new in this business..
I got PE4L, 400W PSU, HD 4830 GPU, Lenovo T420,
I can't get my eGPU detected :[
I tried to run many different ways, basicly connect all the setup, turn on the PSU,
turn on the laptop and nothing :[
Tried with different PSU (500W), and different eGPU (HD 4770) still nothing.
I don't see the eGPU in device manager...
When the setup is connected and the PSU turned on, laptop off, there are 3 Leds on, green yellow and red,
when I turn on the laptop the red turns off, the fan is allways spinning on the HD 4830, on the HD 4770 only when laptop on

please somebody help :[

 

check out tech inferno forums for more help, most of eGPU operations has moved to that forum

 

Trying every possible place I found :]

 

Hello all,

I am new to this forum so sorry for any silly/vague questions.

My setup:
PE4L with a Gigabyte NVIDIA GTX650 2GB DDR5 PCI-E Graphics Card
Lenovo T420 with default system BIOS
Intel(R) core(TM) i5-2520M 2.5GHz
6gb ram
NO dedicated graphics, but internal is Intel HD Graphics 3000
Windows 7 ultimate 64bit.

My egpu has been functioning from the very beginning, and for games it performs very well. However, if I am watching 1080p videos on youtube or downloaded movies, for example, there eventually comes a point where the entire playback becomes choppy and laggy, and the cpu usage skyrockets to 100%. Even if I close all other applications the laptop really struggles.

I have been looking into the 1.x set ups but I am not sure if this is what I need. I tried to disable the igpu through device manager however that didn't seem to work as when I rebooted the laptop, my external monitor was not detected, and the resolution on my laptop was off.

I also read somewhere that somebody experiencing similar problems changed the express card speed to generation 1, which I have tried to no improvement.

Anyway, if anyone has some tips or suggestions on what I can try please let me know.

Thanks!

 

Anyone Got Bottlenecking on GTX750 TI?
