Overclocking Athlon 2600+

Howdy.Iv had this for a while now so im thinkin of overclocking the bugger.Under Sandra2005 it says the processor is Duron M8 and Athlon XP/MP and Sempron(Thoroughbread) 130nm 1.5-2.5Ghz+1.5-1.65V.Whats the best and safest way to overclock it,and does the 2.5Ghz part mean that it should go to that speed no problemo(without after market cooling)its currently at 2.08Ghz the votltage is at 1.63V.Cheers.

 

Come on guys is no one going to help me out here.BTW when I reset my CMOS do I lose everything on my PC.

 

Ok may be u guys just need a bit more info on my system specs eh.
Im using a
MS-6712 motherboard
1026 mem(3Sticks 2x512,1x256 PC2700 166MHz)
KT400 Chipset

 

Overclocking anything without after market cooling is usually a bad idea. How is your CPU temp with stock cooling?

333DDR memory limits your FSB to 166 without overclocking the mem too.
