How do you check if your CPU is unlocked?
The easiest way to tell if your cpu is unlocked is to try to change the multiplier. Set the multiplier DOWN by one step and see if your cpu posts at a lower speed. If it does not change the cpu speed at post, then your cpu is locked and you will have to either modify the bridges or live with fsb changes alone.

Can I unlock a locked CPU?
Locked cpu chips from intel are physically locked from the factory. There’s no hack or voodoo to get around it, you either have a locked (non k) or unlocked (k) chip. You can still raise the baseclock on a locked cpu but baseclock (bclk) affects more than just the cpu.
