your just expecting too much.

4.5 ghz on air, isnt gonna be stable, or easy. even with these.

sure, it can be done. mine can do almost 4.8 on air so far.
but not much is stable past 4.2-4.3ish.
atleast, not to the point where I am willing to push more Vcore into these.

I am still learning the ins and outs of my CPU here.
it OC's insanely, but getting stable is the hard part so far.
these are very jittery little processors.
alittle voltage off, and you will be unstable. yet they boot at almost any speed you set them at.
