I have an AMD 5200+ brisbane and I have overclocked it to 3.0 Ghz. This my first overclock. I am using stock cooler and a slight voltage increase to achieve that speed. I ahve ran Prime95 for 8 hours stable. The I included only shows temps after running Prime95 for a few minutes, but when I ran the test for 8 hours I didn't see temps over those. Should I try and push the speed a little more? http://www.picfront.org/d/eoCpnqAa/screenshot.PNG
Push it until it is not stable then start to back down. take this with a grain of salt don't continue to increase voltage. just because its not to hot doe snot mean the voltage wont fry the chip. find max Vcore online then don't go past that.
