The second K10-based Sempron microprocessor, model 145, was released in May 2010. The CPU uses C3 revision of the core, which now supports two DDR3-1333 modules per memory channel, and adds hardware C1E low-power state. Beside the new stepping, the AMD 145 is clocked 100 MHz faster than Sempron 140, and in all other aspects this this model is similar to 140. Internally the Sempron 145 is still based on Regor core with one CPU core disabled.
