Turbo key and core unlocker question??????

If you are stable at 3.7GHz then don't worry about Turbo Key. It is designed to overclock your system when you press the power button, but anything past your current config proabably won't be very stable.

Core unlocker is a different story. If you have an X4 then disregard, but an X2 or X3 can be "unlocked" to be an X4. Most had cores disabled for a reason so you are hit-and-miss as to its success. There are lots of threads out there for unlocking an AM3 CPU if you want to try it out...
