SLI doesnt seem to be working everytime i put it on I notice a performance drop in games and in 3D mark 06 i have tested both GPU's independently and they both work to full capacity so assume its a software problem i have unistalled the lastest drivers and tried some of the older ones but i see no difference could it be the bios which i did update around the same time as the prob but i am unsure as i only notice the difference in some games eg crysis and not in others as one of my cards could run the game eg left 4 dead.
