Overclocking HD 5750 with RivaTuner

[bl1tz]

Hey guys,

Well I just got my HD 5750 from UPS and am trying to overclock it, however for some strange reason, the ATI Overdrive tab in CCC is totally greyed out, I can't click anything and I can't seem to fix it, and I also tried to look up how to overclock using RivaTuner but had no luck so far, any ideas?

LOL, I'M SO STUPID. I just went in the Overdrive tab and clicked on the lock thingy and a message popped up warning me about the risks of overclocking and it's working. WOW. Sorry guys, hehehehehhehee.
QUESTION ANSWERED

Well actually, I used the Overdrive, and my HD 5750 is running at 870/1380 but 870MHz is the limit for the ATI overclocking tool, so if anyone knows how to overclock with RivaTuner or other reliable OCing program, please give me a hint. =D thanks.
