It is a "black edition". Isn't the multiplier unlocked ?
Change the multiplier.

See section 3.4.1 and "Multiplier/Voltage Change". Use
CPUZ from cpuid.com, to verify the changes, and make
only small changes so you can understand how it works.

You can give it a little more voltage, as you explore the
speed it is capable of. You need to know

1) The nominal value. What does it need, to operate at
the stock speed. The hardware monitor may show this
value, when the computer is idle.

2) The maximum value. There is some value which will damage
the CPU. It helps if you know what that value is.

3) As you increase frequency, eventually the computer will be
unstable. If you proceed in small steps, the computer will
not completely crash, but may only be unstable when Prime95
is running. You increase the voltage a step or two, and
rerun the test.

If you plot the values, you might see something like this.

Voltage +---------
|
+-------+
|
-----+ Frequency

The slope of the best fit line, through the points, gives
you some idea how much voltage it would take to reach
a particular frequency.

If you need raw data, see hwbot.org . Some of the results have
screen shots, and they may include voltage information, or other
settings.

Also I would suggest you make sure cool&quiet are disabled or you may
see many problems whilst trying to overclock.
