For my new build I'm using a Biostar TA 970 with an AMD Sempron 145 2.8 GHz processor, and although I'm happy with the way it's performing, I'd like to juice it up a bit. From what I've read Semprons are unlocked and can easily be overclocked to 3.6 GHz and beyond, so I went into the BIOS to increase the processor's multiplier, and there is no option to go above 14 (14 x 200 FSB = 2.8 GHz) on the multiplier. The 970 is a fairly modern board so surely it must have CPU overclocking abilities... what am I missing?
