it seems that a cache line would not become eligible for snooping until at least 2 processors had read data from the same location. it is an excellent machine for general computing. - by rick c.

AMD was the first x86-family vendor to implement no-execute in linear addressing mode. it shows the promise of the os, and the current lack of graphics driver performance at this stage of development. exit2dosNov 24, 2006, 6:26 AM Quote: Nowhere on the Vista site does it differentiate between the 32 bit and 64 bit editions... From an IT support perspective, processor architecture means Windows architecture, and multiple Windows architectures in an organization means multiple versions of everything from Windows source files to service packs to drivers.
