overclocking the x1900xt

[kingdomwinds]

I successfully overclocked my x1900xt yesterday to 697/1600. But after getting lockups in games, i tried to oc again. I got an error in overdrive and was not able overclock to those sppeds again.

So what is a good utility that overclocks cards to safe settings? I noticed that ATI tools is not soo reliable when it comes to overclocking

I use the CCC, you have seen where your card is going to lock up, lower the clocks and try again...
good luck

I dont know what to tell you there, you could try using driver cleaner to totally clean out the driver and reinstall them...? sometimes is better than others I gusee.
