Trouble detecting 2 GPU's in Vista 64 (MOBO P5n-d)

Hi all!

Just switched from a p5n-t deluxe motherboard to a p5n-d motherboard. Since the switch I haven't been able to find the 2nd GPU (graphic card). There is no SLI-option in the nvidia menu.

I have made sure the card is connected etc, but no luck at all. Is there a setting to enable this or any strange bug with this motherboard that requires some patch to allow two Graphic-cards in SLI-mode, any setting in the BIOS etc?

How can one solve this problem?
Thanks!

 

1) If your gpu's have power connectors, have you plugged in the 6-pin power cables?

2) Is the SLI bridge hooked up to the 2 cards?

You can try clearing cmos as well. After these, nvidia driver should detect the SLI setup and the option will be available in windows. If still no luck, uninstall nvidia driver, restart pc, install it again. Might want to look for a new driver from nvidia.com.
