GPU overclocking capped?

I'm new to overclocking and want to OC my graphics card, so I thought I'd start out with basic stuff. I've got a 6850 and am trying to use the Catalyst Overdrive function, but the slider for core clock frequency is capped at 850MHz.

Is there a way to get around this in a fairly simple way? I understand rivatuner can take it past its limit but am I right in thinking that I would have to re-oc it every time I turn the computer on; compared to Catalyst which applies the setting automatically upon booting up?

    You can use MSI afterburner (based on rivatuner) and make your overclock start at login time (it's what i'm using for a long time now)

    You also have more option with it like setting up a custom fan curve and voltage adjustement...
  2. That sounds like a good idea, didn't know you could do that with Afterburner. The thing is, I've downloaded that program but it won't launch: "Some of MSI Afterburner components are expired, missing or corrupted!"
  3. try to reinstall and make sure to have the non beta version of the official website ( V2.3.1 as of today as all their bata have an expiration date so unless you want to update frequently the program, grab the stable version...
