Asrock 970 Pro3 R2.0 + Athlon II X4 640

Hi all,

 

I need to ask some question about OC'ing my pc.

 

My system specs are:

Athlon II X4 640 @3000MHz (Stock)

Asrock 970 Pro3 R2.0

Visipro DDR3 2x4GB PC12800

HIS R9 270 ICEQX2 Boost Clock

 

Proc temp:

Idle @21-25

Gaming @40-45

 

According to Asrock's website, this mobo has a 4+1 phase (I know it's bad for heavy overclocking) and support FSB 2400MHz (4.8 GT/s)

 

Since my processor has a locked multiplier @15x so the only way to OC it is to play with HT Ref clock so it will affect HT Bus speed and RAM to (OC'ing it)

 

The stock multiplier is 15x200 = 3000MHz

 

I'm not going to OC much, I just want to reach 3300MHz with a stock cooler and not to mess around with the voltage etc.

 

Now, the questions are:

 

1.If I lower the HT multiplier from 10x to 9x in BIOS, the pc will shut itself down makes a clicking noise and then turn itself back on, is it normal? (Almost gave me a heart attack when it happened)

 

2.Let's say if I didn't lowered the HT multiplier to 9x keep it @10x and up the HT Ref Clock to 220 in order to reach 3300MHz (15x220) the HT bus will run @2200MHz from the default value @2000MHz is it safe?

 

4.Do I need to lower my RAM freq to 553MHz from 667MHz? with 15x220 scenario?

 

3.If you guys got any advice on how to OC my pc to reach 3300MHz max any advice will be appreciated.

 

Sorry for my bad english, I'm not a native speaker, Thanks in advance
