How to overclock multi GPU's?

[newgeneral01]

Im kinda new to overclocking and i just finished overclocking my 8800gts 640mb with ATItool, i immediately see a performance gain in crysis. Went from medium settings to high with almost no lag at all. Now i am trying to overclock the second GPU and make it the same speed. However i don't see the menu for my second GPU. I enabled Sli and checked if that helped, but it dint. My question is, how can i overclock bough of my video cards and then make then run in SLi to increase performance? Thanks

Do you actually see options to overclock each card separately? From what I recall when you overclock one, it automatically overclocks the other.
