Dear Wbmw: You say you like debate, but your style leaves a lot to be desired. As to what could be keeping Barcelona clocks low, it has been suggested to be speed path issues. Else they could raise clocks by cooling the CPU more, if it was a thermal problem like the Intel IDF demos with phase change cooling or LN2. Speed path issues can be hard to find and thus, fix. But once done, speeds can shoot up in a single step. Tbred-A was such an animal. It turned out to be needing more decoupling capacitors on the die. 4% more die area and it ran 600MHz faster (1.8 -> 2.4GHz). If the same was true for Barcelona, we could see jumps of 600 to 800MHz in one stepping (to 2.6-3.0GHz). Given that at 55W TDPmax, Barcelona HE runs at 1.8GHz already, it doesn't appear to be thermally limited. Pete
