Specifications

ADX245OCK23GM was one of the first dual-core microprocessors with newer C3 core stepping. This stepping came with a few notable features, such as new C1E low-power state, implemented in hardware, and generally lower power consumption and cooler operation. The C3 stepping also fixed errata in C2 core revision, where the CPU could not reliably access DDR3-memory when each memory channel had more than one memory module populated. C3 core can be identified by "GM" suffix in the part number. Performance-wise the ADX245OCK23GM is similar to "GQ" model.
