AMD Optron 165 @ 2.4 Ghz How how can i go and how much do i raise voltage to go highe

CPU frequency: 2400 (260 x 9)
CPU voltage: 1.35 V

motherboard: Asus a8n-E
memory: G Skill (1GB X 2)
memory timing: 3-3-3-8 1T
memory voltage: default
HT frequency: HTT x 3
power supply: Antec NeoPower 480W

I want to achieve the highest possible overclock and this is my first time overclocking and i want to be very cautious in increasing the voltage. I hear that these cpu's can achieve around 2700 MHz. I dont know how to configure my voltages to achieve this.please help.

first what kind of memory are u using just as test drop the memory devinder to 166 and check if you can overclock more
for the vcore to stay safe i would say 1.55 v is max remenber to watch your temp keep it as much as possible bollow 50C

Im sure yoiu can get lots more out of the chip, do you know the stepping?
