i am running 2 9800gt's on a XFX Nvidia 790i ultra, i have overclocked cards before so i know how to do it, is there a diffrence in sli?

Do both cards have to run the same clocks?
Can i overclock each card seprate or is it better together?
Does the 9800gt provide good overclocking?
Any thing else should i know?

Thoughts and suggestions please

PS i read somewhere that you have to flash your card bios to overclock with sli setup, that driver overclocking (rivatuner) doesnt work when using sli. Is this true because i dont feel up to flashing my cards bios

for SLI o/C the cards you have to make sure the cards have the same clock on both memory and core and shader and all that.


if not the SLI will either be

a- not stable (crash tastical!)
b- it will go and down clock the faster card to the slower card

most likely with an O/C answer = A


*Not 100% sure on the flashing part i have never heard about it, and as for 9800GT being a good OCer its basically a rebranded 8800GT with some added goodies so i believe it is :p .
