SLI Overclocking? Core/Mem speed?

[^^^Floorkiller^^^]

Heya all!

Long time since my last post on this forum :rolleyes: .
I have a kind of n00b question about SLI and how its running under DEFAULT SLI configuration.
I have today a Gainward 7800GTX at 470@1300 but i would like to pair it up with another exact same type of card.
I have seen sites that have tested SLI in benches but at speed 420@1200?

Now, what i would like to know is, if the core/mem is running in a SLI kind of speed and if its possible to overclock SLI setup.
I have not come across so many sites/forums where SLI overclocking has been spoken about very mutch.
So if there is an master/guru in this matter feel free to fill a poor mans mind :p .

/Thx and keep up with the O/C ..

I would like to know the same. I have 2 7800 GTs in SLI format. I can only run them at stock speed. If I try to OC them, it fails the test, no matter what, even if i try underclocking them. Someone had mentioned turning off the test in Riva Tuner. How do I go about disabling the test in Riva tuner?
