Help

i overclocked my CPU 2 day.
i set the clock frequency to 13X and the CPU Frequency to 220
which makes it 2.86 Ghz
my cpu is 2.6 Ghz PDC E5300
i made it 2.86 cause i think its not taking too much power or HIT.
MOBO is Gygabite G31-M

so after done..
i restarted with pressing F10 > y
i found the CPU 2.86 @ the BOOT Start up Report.
but when i logged in windows. i found it 2.60
the PCWIZARD & CPU Z shows the same.
