A newbie making progress overclocking my CPU after unlocking to four cores. Now at 3,950 MHz on 219 FSB and 18x multiplier through BIOS changes. Have not changed the voltage which is as 1.344. Running Prime95 for hours and temp has reached 33C. Should I continue to push higher? If so, which parameter? How do I change the voltage? In BIOS? Where? Running AMD overdrive too. If needed, what do I look for to adjust memory timing? How?
