Is it possible? I read this: http://www.emboss.co.nz/amdmults/ and it shows how to do it for Athlons. My Sempron is Barton Core, so I guess it may work. Any ideas? If it works, which mod is the best for me? (Without the mod I can reach 2.4GHz with 12x200MHz, but I wanna know what's the max overclock this Sempron can give me... would it be possible to reach 15x200MHz = 3GHz)?
