Thanks, -Kai ________________________________________________________________________ ____________________________________ My experience with the AMD HE CPUs has been that the scaling breaks Win2K3, and any virtualized environments. -- William Pitcock SystemInPlace - Simple Hosting Solutions 1-866-519-6149
