I was running a stress test and incrementing my 4870 by 3mhz to find the max core clock at a stock voltage and it crashed at 832mhz. Ok thats fine... I bumped up the voltage from a stock 1.26v to 1.5v and that didn't do ANYTHING. Am I going crazy? I could've sworn that 0.24v would stabilized it at least A LITTLE!!! Any ideas?
