How to Lock Multiplier and turn off Speed Step
Step 1
Enter Bios
Step 2
Go to Advanced Tab

Step4
CPU Ratio Adjustment set to whatever the max is for your CPU I beleive it is 9 for a Q6600
Step 5
Disable C1E Support
Step 6
If the Intel SpeedStep one is still there disable it. It should disapear though when you lock the multiplier to a set number.
After you completed this you will have disabled speedstep completly.
How To Overclock The CPU
Preperations: Make sure you have adequate cooling for your case and processor
Step 1
On the same Advanced menu Go to JumperFree Configuration
Step 2
AI overclocking Set to Manual
Step 3
CPU Frequency-This Is the actual bus speed for your CPU so whatever you set this to you multiply it by your multiplier you just locked it too which I beleive will be 9. So lets say you want 3.0 GHZ. You will set this to 334mhz which will be multiplied by 9 will give you a clock speed of 3.0GHZ
Now you should be overclocked when you save and restart the computer for now leave the voltages alone and let the bios set them If you become unstable you will have to raise the Vcore up a little the Max voltage intel recomends is 1.5volts so I would make sure I stay under that
Good Luck hope this helps.
