im lucky my e2140 came as part of a combo with a ASRock system board which BIOS is set by default to overclock this cpu up to 2.6GHz without increasing voltage^^ it is a very good processor though,for the money it costs, and has great potential (some overclocks reaching 100% (3.2GHz stable) shame mine wont go past 2.775GHz) =)
