In the family K10 ago Phenom X4 II and 4 cores, variants X3 and X2, Athlon X2, X3 and X4 and Phenom II X6 soon. But there is also a processor with one core, the Sempron 140. Indeed, the Sempron "Sargas is a 45nm K10, based on the core of the Athlon X2 II but with only one core active. Clocked at 2.7 GHz is a good solution to upgrade the machines AM2, especially considering its price. And our fellow Belgian wild shrimp have decided to check what he had in his stomach.

By cooling the CPU with liquid nitrogen and using an AM2 + motherboard (with DDR2), they reached 5.5 GHz, more than double the original frequency. In AM3 (DDR3), they failed to exceed 5GHz, although it is still interesting. As we see, AMD has some leeway with its processors, although obviously the liquid nitrogen is not very common outside of overclocking competitions. Note that the Sempron 140 can be transformed in some cases Athlon X2 II, but the pattern of our colleagues was not amenable to this little game.
