DIY Dongle for ATI for display only + Nvidia for CUDA only.

[arexma]

As I successfully ran cards of both camps in one machine already, but neglected that fact that many don´t want or have a screen to connect to the Nvidia card and now got asked in PM quite often:

You need to patch up a DVI dongle. What it basically does is, it makes the card(s) think a screen is connected, and thus installing the driver and activating the card.

I guess everyone already has a drawer full of DVI>VGA converter plugs, all you need is 3 resistors and ram it into the VGA end and plug it in.
Here´s a DIY manual:
