That CPU is easy as shit to OC
Just do exactly as I say
I had an Athlon 64 X2 4600+(2.4)
I got that to 3GHz before it hit max TDP
What you have to do is, Slowly increase the FSB (5mhz each turn) until it turns off, then up the voltage one notch and continue until it won't go up anymore
Your CPU will get to 3.2GHz comparable to mine(higher stock clocks)
If you need help, call me
//Your FSB seems pretty weak... try incrementing to 250MHz(in 5mhz bursts)
Also 65W? That could be trouble, mine is 95W...
