Could somebody explain how to overclock from my bios? I tried using the AMD overdrive, but for whatever reason it says I do not have the 740g chipset even though I have the 740g on my motherboard which is a gigabyte ma74gm-s2. I need to know 1) what ratio to set (2.5-11 in increments of .5) and 2) what voltage to set my CPU to. I have an AMD Athlon x2 2.31ghz processor and I need a slight performance increase until I get my Phenom.
