i have oc many 1366 and 775 CPU before,
but i have bo idea in oc AMD chip,
can someone give me some basic parameter??
Yea, the main settings are going to be your Vcore, your multi, and your CPU/NB. I would start setting your vcore to somthing like 1.40v, and change your CPU/NB voltage to somthing like 1.25v-1.30v. next step is to raise your CPU/NB freq up, not the NB but the CPU/NB. you want to start around 2600. if its stable you can jump to 2800. for you CPU, use the multi and set it to 3.8Ghz and then its time to check temps and run prime95/IBT to check heat and minor stability. if your temps are under 55c per core then you can bump your CPU/NB freq to 2800 and your CPU to 4.0Ghz. and your done. pending on your CPU cooler and case flow you might be able to hit 4.1-4.2
Overclocking the CPU/NB will help you with stability alot, and give a nice performance boost. CPU/NB overclocking is great!

I have a problem, I want to increase NB frecuency =2400Mhz, Which parameter ?
NB voltage or CPU-NB voltage ?? 1.20v or 1,25 v ?
For overclocking your NB to 2400 your going to want to change the CPU-NB settings, not the NB settings. the voltage is the exact same limits as your chip, so try to keep it under 1.45v-1.47v if you can. also don't even bother with only 2400. Set the voltage to 1.30v and crank it to 2600. if that is stable them jump it to 2800 and your good. After that there is little performance to be had.
Keep in mind adding voltage and overclocking the CPU-NB will add heat to you CPU core temps. so watch them closely and enjoy.Edited by KhaoticKomputing - 2/17/12 at 7:53pm
