I have experienced this with 2 overclocked processors. The current one is an Intel E3300, stock is 2.5GHz (200*12.5). I pushed the fsb from 200 to 300, giving 3.75GHz (300*12.5). However, the cpu scaling shows 3.33 2.67 2.13 1.6 GHz. I'm guessing the standard stock speeds it is adhering to are based on 266 fsb. 266*12.5=3.33, 266*10=2.67, 266*8=2.13, 266*6=1.6.

"cat /proc/cpuinfo" & "cpufreq-info" show the wrong frequecies.
"dmidecode --type processor" shows it at 3.75GHz all the time, no matter which frequency was selected in CPU Frequency Scaling Monitor.
