alright, i understand the forceware thing. now am i doing something wrong...my 2d clocks and 3d clocks seems to only accept one memory speed. like i can set my 2d core clocks and 3d core clocks different and it's fine. but for memory, when i change one, it seems the other is also changed for some reason. also, is there a reason why i cannot overclock with rivatuner or coolbits at all when i unlock the pipes of my 6800? (i can't even underclock for that matter). i can do it with the utility gigabyte included and it works fine, no artifact at all. it seems what i have to do now to overclock with rivatuner/coolbits now is lock the pipes, raise the clocks, and then reset and unlock the pipes. is there a better method for this?
