DIY eGPU experiences

[kizwan]

As far as I know, there are at least two version of Toshiba A505; one with Core 2 Duo + Intel GMA 4500MHD, while the other one have (1st gen) Intel Core i + Nvidia GT310M. If the latter, you will not be able to use internal LCD with eGPU, without little tweak. You can use Ultramon/Chung Gun method but you still need external monitor. However, with this method, games only work in windowed mode & performance will be reduced. If your notebook have either Intel GMA 4500MHD or Intel HD Graphics or Intel HD 3000 iGPU, you can use & get acceleration on internal LCD, if you use Nvidia Fermi desktop graphic card. Both Intel iGPU & Nvidia Fermi are needed for Optimus setup.

Hi everyone,

Been doing a lot of reading and finally got the stuff to get the egpu running with the nvidia gtx 550ti on my lenovo t420.

I plugged it all in, bios is 1.15 (i have 8gb of ram), did a clean install of windows 7 professional, and installed the intel hd drivers (for intel hd3000), and then reboot, installed the gtx 550ti drivers from the official nvidia site.

It just gives me the "Windows has stopped this device because it has reported problems. (Code 43)" everytime.

I've tried the modded drivers, with no luck.

I tried doing the setup 1.x doing the pci compact thing, and ran the startup.bat, and chainloaded with windows 7 (using mbr didn't work somehow since it just says "missing operating system".

Am i doing something wrong? Am I missing something?

I've been working on this for over 10 hours today. I'm going to head to bed.

I hope you guys can point out somethings for me to check on because I'm just stumped at this point.

Thank you!!

Now this sounds good.. so is it only the edge S series that is going to have TB or even E series..? But think these laptops will be release only during sep-oct not before..

if the notebook had hdmi port
and connectting hdmi on laptop to mini hdmi with an converter
dirrectly to PE4H or PE4L can it work ??

I'm wanting to upgrade to an adapter that supports Express card 2.0 (I assum the old PE4L on the ViDock doesn't) to get x1.2Opt working on my setup. Do you suggest grabbing a PE4H now or waiting for the v3 to come out?

No, that HDMI port is output only and can manage only video signal, the mHDMI ports on PE4H or PE4L are in/out and can manage both data and video signal

@xtraman122: considering that the culprit of the failure in negotiating PCI Gen 2.0 is the connector, i think the PE4L inside the Vidock is able to handle it (due the cables are soldered to the PCBs). The PE4H sold now can only handle PCI Gen 1.0 for the same cause,

it's mean i must use PM3N or EC2C ?

Yeah, PE4H/PE4L + EC2C/PE3A/PM3N only.
