eGPU first time start no display

Hey guys. So I got this far.

Connected the laptop HP EliteBook 8460p i5 2450M to this ASUS Geforce GTX 750 Ti 2GB GPU via an express card /34

And this resulted in my laptops display not initialising which was to be expected I recall reading on different threads here.

My second monitor is using hdmi so I tried hdmi on the gpu and also connected a hdmi to dvi adaptor to the laptop and sadly the monitor never detected anything,

Can anyone help make sense of this with me?

 

BTW I connected the egpu while the laptop was off. Then powered the laptop on

I do believe that the 24-pin ATX connector is meant to go on the PE4C.

I have attached the 24pin ATX connector directly to the PE4C and now both fans from the gpu and psu dont run.

 

Seems to only run when I have the 24pin ATX seperate with a "tester" cap on it, like in the picture.

 

The only power that is connected is a 6/2 pin to the gpu which is connected directly to the PE4C and a VGA ATX 6/2 to the PE4C power slot lower left, also like in picture.

Adapter may be kill.

 

I don't know if this applies to PE4C, but on EXP GDC it should turn on the PSU when the laptop starts up.

 

I stand to be corrected, of course. For all I know I'm talking out my arse.

Whats the function of the SW1 and SW2 switches?

  • Support two delay switch to avoid registration problems when boot. (SW1, SW2)

 

Also cant do anymore till my laptop arrives, dont want to blow up my brother laptop

I plug my eGPU after windows has started now. Because whenever I run it while already plugged in I get that screen.

Also I used a GTX750TI like you before as well but my laptop didn't have enough resources so I used the GTX660 from my desktop which was fine.

I could use the GTX750TI as well but I couldnt get Nando's DIY egpu Compaction feature to work

 

This is my contribution to this forum. My procedure and setup that worked.
