Hello,
I bought a cheap mPCIE to PCIE adapter on ebay some time ago. I plugged it into my Samsung R530 along with a HD5770 and it worked right away. But I couldn't use 4 GB of RAM and couldn't get the DSDT-override to work. So I let it rest for some time.
Now I'm giving this another go and this time the GPU isn't detected. Neither by eGPU-Setup not by Windows. I tried plugging while sleep and after BIOS but nothing works. Also the fan of the card isn't spinning but the plug for the fan has between 10 and 12V. So I guess the card is powered. The card also gets a bit warm.
When I hotplug the adapter the Laptop goes blank or shuts down or nothing happens. Taping pin 22 doesn't do a thing.
The only thing that changed is a new processor. It was a T3100 Dual-Core and it is now a T9300 Core2Duo. But I don't think this is the reason it fails to detect.
I've ordered a new adapter of ebay but it will take some time to arrive. In the meantime, does anybody have another Idea?
