I've just loaded Ubuntu 12.04 onto a brand box with an AMD 645 quad CPU with 8GB RAM. In the BIOS it says, the CPU is running at 3100MHz. However when i boot into Ubuntu 12.04 it says 800MHz?
I've checked using:
cat /proc/cpuinfo command from the terminal and running System profiler and benchmark application. Both say 800Mhz at each core?
Any ideas or input would be much appreciated.
