you should be able to push at least 200Mhz to 2.5 GHZ. All you have to do is go into the bios (usually by pressing delete when the computer starts go into advanced features or another tab in the bios that specifies it is for overclocking and up the FSB by about 5Mhz then reboot and do that again. When you go to high the comp wont start so remove the bios battery on the motherboard reset the Phenom to the speed you thought it was stable at and then run prime 95 overnight to make sure it stable. If not then lower the FSB
what mobo are you using? can you list the rest of the specs? isn't the 9600 with the unlocked multiplier? i think that in bios you can simply raise the multiplier to overclock second next best thing is to overclock the fsb. i have mine at 228x11(mulitplier) gives my phenom 9500 2.5ghz speed.
I have a 9600BE and I had it OC to 2.4 By Muti. 11.5 to 12 But I cant get it any higher. its stable at 2.4 by the PC hangs if its any higher. I know that the B2s dont overclock well but I hoped to get 2.5 I will upgrade with the 45nm in Q4 for something faster.
