Overclocking in SLI mode with nVidia cards...

I'm having doubts about it because I'm confused... let's say I use coolbits to OC when SLI is enabled, is it one card running at faster speed or two cards running at faster speed?....cause I sure don't like the idea of one card running at 325 mhz core while one the other runs at 420..... anyone know if two card are actually being OC? thanks for reading :)
 
One of SLI's requirements is that the two cards be identical in every way, including frequencies. If you overclock one, you have to overclock both.
 
How do you know if you've done both when in SLI mode. If you use the slider in the nvidia control panel does it do both or just the primary?

SLI mode wont work properly if only one was done, that's how you know, heh.
 
yes, both cards are treated like 1, makes windows not have work too hard, everything you do is applied to both cards, its only in the nvidia driver behind the scene that its treat as 2 cards. Both cards have to be identical, if one was overclock and the other wasn't, it'd crash, so coolbits does both cards.

also editing the bios = very risky and warrenty destroying, only do it if you 100% its stable at the speeds you edit for and don't mind really living on the edge.

Thanks for the clear answer. I had been wondering about this too.
