There is an option to disable in my laptop (intel cpu+amd dGPU) in the bios and I think its a whole different story for the AMD APUs I guess.

Oh okey alright I see it...I think at this point man I guess you really need to use Tech Inferno Fan setup 1.30. It's your last option I believe. Just PM him for details.

That was a quick response, okay i will try to contact him later. Thanks!

Whoah this is such a whole different story now buddy wait a sec,

I did not know you had an AMD CPU, I guess you got all the steps right but I am trying to remember how I did mine at those last few steps, I remembered when I installed the Catalyst Desktop version, I did not reboot yet and checked my device manager, it shows the eGPU (initially attached and powered) as "Microsoft Basic Display" adapter. I would then push on the combination of FN plus the display function to select only my led monitor and it did went ok and I then rebooted. Now once the laptop boots up with that brand it will directly connect to my LED TV monitor and boot normally to windows 8.1 lockscreen. Although it took a while to boot up to windows 8.1, I knew why its maybe because it is performing the initial pcie compression to accomodate the eGPU electrically and integrate it into the system but neither that I experienced a BSOD unless I put that pcie reset delay button to the right side, it would display only weird artifacts.

Maybe it's an AMD APU thing..sorry..couldn't help more

Oopsie my bad!!! here I forgot one step!!

disable dGPU in the BIOS option and choose iGPU only!!!!

Don't choose switchable graphics, use integrated graphics!! shown here below

Try that and tell us what happens!

I should create a new thread for discuss my problem on there, sorry..

Thats what i thought a few days ago, i have to disable igpu on BIOS, but it seems there hasn't the option to disable it on my BIOS

screenshot:

I tried to contact samsung support (my laptop model: 535u4c), but they didn't released the newer version BIOS for my laptop

Maybe there was an option (disable igpu using cmd) or something like that?

Tried your instructions still not worked for me

Here's the detail:

Your last instruction told me to install amd driver 14.9 (not the beta version) with egpu attached to my laptop. It went smooth until i accepted to reboot, before the windows go to my desktop (there's a windows 8 icon starting up windows), it went bsod (it's said atikmpag.sys) and rebooted again and again until i unplugged the egpu.

Tried to hotplug method was not worked at all, it's not detected my external vga.

The last method i tried to disable my igpu first, then restart the windows (while the windows was restarting, i plugged the egpu).It went to the desktop with no blue screen, and i checked to device manager and my egpu (R7 250) was showed up with no errors

Screenshot:

I checked the egpu with HwInfo software, if you see the current clocks its 13.6Mhz. When i check my igpu (HD 7550M & 7600G) the current clocks was 199Mhz. And i thought the external graphic card was idled, am i right?

But now it still cant showing up to the external monitor, went to display settings and detect external monitor.. nothing appears

Any suggest?

Wait

Do this carefully step by step.

-download and install DDU Uninstaller.

-download desktop AMD Catalyst 14.9 WQHL driver

-download latest intel hd graphics driver

-run DDU uninstaller and remove AMD graphics first (just follow prompts, Clean and reboot)

-run DDU uninstaller again and remove Intel graphics driver. Reboot

-install intel hd graphics drivers reboot

-install AMD Catalyst 14.9 WQHL driver with your eGPU attached to your PC powered on (don't worry this is completely safe trust me) Reboot

-once it has booted, just press your FN+Display button and select secondary display only and enjoy your setup

are this steps is reffering to me or @cchoo?

Hi,

Desperately need your help!!!

I have Dellstudio 1555 + egpu sapphire ATI R9 270 + igpu ATI Mobility Radeon HD 4570. I failed to install the driver. My external screen is blanks.

This is the version I installed. But it failed when installing the driver.

Catalyst Software Suite 14.4

I try to find the DNA driver, but nothing match with this new card R9 270.

Any suggestion or ways to install the AMD driver for both igpu and egpu?

The hardware is working fine, as I already try using lenovo T520 with Intel graphic inside, and it working pretty well.

Thanks

I'm having same trouble with ccchoo, the external screen was blank after i plugged egpu. I'm using windows 8.1 and 8gb ram, tried to detect external monitor on display settings nothing seems to appear...

maybe the problem is to try the nvidia card first, if the card is success to display the external monitor, it could be the amd drivers problem

hey darkydark, you can use (br /) change the () with this <> it should work to "enter" your text. and dont forget to use the html on-convert linebreaks

Hi, i want to ask a few questions about eGPU for my laptop.

Here's the detail:

Samsung 535u4x

8gb ram

a8 4555m 1.6ghz

Display VGA Dual Graphics with 1GB gDDR3 Graphic Memory

win 7 64bit

PE4L pm060a ver 2.1 (mPCIe)

PSU 500w

HIS Radeon R7 250 1gb ddr5

i've tried to plug in the PE4L mpcie cable to laptop wifi card slot before boot up the windows. When i was booting up the laptop went BSOD (atikmpag.sys error, i've already check this error it was a driver error from amd).And i've tried the hotplug too (sleep mode the laptop, turn on the egpu, plug in the cable, resume my windows) and when i check on device manager, it wont scan my ext VGA.

Here's the screenshot :http://i59.tinypic.com/nxw2ub.jpg

Tried to switch SW 1 and SW 2 repeatedly it's still doesn't works

My questions:

1. Did i miss something like setup 1.xx (as Tech Inferno Fan said) should installed to fix this?

2. was the Radeon R7 250 supported to do an eGPU?

I've seen many peoples were succeeded to run eGPU with Radeon HD not the R series, maybe the vga was supported only on pc desktop
