Which generally means that you are only supposed to use ASUS proprietary tools for overclocking their cards.
Probably done to ensure their customers don't overdo things !
When looking at Core Speed in Rivatuners Hardware monitor, what does it show for 2D ( desktop) and 3D (game, 3dmark, etc) activities ?
I disagree with you here. I have used either coolbits, coolbits 2, or nvtweak on my ASUS V9980 Ultra from the time I owned it. I've never used ASUS' software, I've only ever used official drivers from nvidia's site.
