AMD64: CG Stepping

Unlike C0-stepping chips which have energy saving mode at 800MHz, 1.30V and respective 35W TDP, the CG stepping differs by Cool'n'Quiet at 1000MHz, but 1.10V and thus 22W TDP.

I think the main point of CG is in improvement of the memory controller.
AnandTech reviewers keep on writing (see new Aopen board review) how 3200+ isn't capable of going much over 2.2 GHz yet I am able to run it at 2.5 GHz and so are many others. The main problem I found with 3200+ is its inability to handle large banks, many banks, and higher memory frequency. That is nothing else than a flaky memory controller on the chip. Memory handling has been AMD problem for ages and it is also again with Hammer.
Lets hope that CG goes further than C0.
