Does 4850 Work with K8N-SLI

Just wondering if a single ATI Radeon HD 4850 will work with a Gigabyte K8N-SLI? I'm almost thinking not because the board is a "SLI" meaning nVidia. I'm still waiting for Gigabyte support to respond.

Thanks.

For some reason, mine won't work. After I installed the 4850, the system doesn't display anything. Seems it's stuck or something.

Current Setup: AMD 64 x2 4200, OCZ ModStream 520watts with 6 PIN power connector, GA-K8N-SLI, 2x Geforce 7800 GT

Steps took: 1) unplug system; 2) remove old cards; 3) set mainboard to "normal" mode; 4) install new card; 5) connect 6-pin and dvi cable

Seemed it would be so simple but it just sits there.

Thanks.

Try re-seating the RAM as well. unplug the computer, remove the old cards and the RAM. Put the RAM back in and then try just the 4850. if nothing happens, try it with just one 7800GT. should work after re-seating the RAM. Don't forget to install the right drivers for the HD 4850. Probably should uninstall the drivers for the 7800GT's first, then install the HD 4850.

Pretty much tried all suggested so far:

1) BIOS -> loaded default settings; also cleared CMOS.
2) Memory -> reseated; downsized to 1 Gig.
3) 4850 card -> moved to different PCI-E slots.

I can see the little red light blink momentarily on the 4850 card. Then, shutsdown. Then blinks, then shutsdown. Keeps repeating and my PC never boots up.
