AMD Driver Crashing Issue on eGPU

[buzzytheblue]

Hello all, I recently picked up a Lenovo T430 as a replacement to an Asus laptop of mine. Soon after it arrived  I found that the expresscard slot could be used for eGPU setups. So, I decided to try my hand at it. I have reached a bit of a roadblock though.

 

Laptop Specs:

T430

i5-2520m

8gb RAM

120gb SSD

 

Board being used  PE4C-EC060A V3.0

GPU: ATI Radeon 5670 512mb

 

I am able to run an external monitor off of the eGPU and it does not show any errors (12) or otherwise. However, after working flawlessly for anywhere between 1 and 5 minutes, the display driver begins to crash every 5-10 seconds, freezing the computer completely. I managed to open MSI Afterburner for a moment before the driver crashed and saw that each time it did so, my eGPU usage spiked to about 80-100%. Not sure if that is relevant, but I found it odd. The 5670 does not require external power and the PE4C is connected to an EVGA 430W psu via the mobo power.

 

I'd appreciate any input anybody with more experience has on this issue.

 

Thanks,

Zach
