Thread Starter 
Im new in overclocking and i want to overclock my e2220 cpu but i dont know how.smile.gif
I have Intel dual core e 2220 currently working on default speed (2.4 ghz) and motherboard Asus P5KPL.Also i have 3 gb DDR2.
Any help??

I had two of these, one got up to 3.4ghz stable, the other around 3.3. I needed around 1.50 Vcore on both chips.

Overclocking these chips is pretty simple - change the default bus/baseblock from 200mhz up to something higher. The stock multiplier is 12x (200 x 12 would give you 2.4ghz), which is fixed by Intel.

For example, change your bus to 233mhz would give you 233*12 = 2.8 ghz; 266 would give you 3.19 ghz, which your chip should do with 1.45V and up. So basically, go into bios (by hitting delete upon system bootup) and up your bus to those speeds, and see if system is stable.

I made it to raise using oveclocking profile up to 10 % because im not sure what will happened.I have option to raise up to 30 % but i dont know if my system will be stable.What your opinion?

Try to avoid the automatic overclocking feature, because you have absolute no control what's going on inside. I'm not too familiar with your board, but there should be an option to enable manual or "advanced" overclocking. Let me know once you find it.

For stability, the first thing to do is see if the system will even boot up windows. If the PC restarts or blue screens half way during startup, then you know it's NOT stable!

If everything boots up fine, then use a CPU stressing program, such as Prime 95 (google it), to load both cores to 100% and see if errors or blue screens develope. But if you follow my advice on Vcore and bus mhz settings, you should be atleast somewhat stable.

But before you go that far, what cooler are you running?

Also i have Windows 7 OS which is not comptabile with PRIME 95...

First, set it to "manual", and try 233 mhz bus/base, with Vcore at 1.40V, should work fine. Then try 250mhz.

Prime 95 works with all Windows. I'm using Win7 x64 myself and Prime 95 works perfectly.

I tried with 233mhz and my cpu temp is about 37C and i think its ok for me because i dont need more GHZ. 2.8 ghz its very good.Thanks men biggrin.gif

No problem.

But, we've all said "don't need more ghz" at one point, and trust me, it won't last long wink.gif

stop overclocking your pc, you have a crapy cooler and if your ram and psu are low end you can fry your pc.
