Hey guys... do you change bios settings then let AOD do the rest?

My AOD says
System is tuning, and this may take several minutes to several hours.

Current CPU clock is: 223 MHz
Current HT Link ref. clock is: 223 MHz

AutoClock is finished successfully!

So if i go and change my multi in the bios will my pc crash?
At 223mhz im only at 2787 MHz
If i raise the multi first and then run AOD it crashes after 3.0ghz
