To overclock your cpu you gotta learn how the core speed of your cpu works
The basic overclock:-
The core speed of your cpu is =
Front Side Bus x Multiplier Ratio
So lets say Your cpu is clocked at 2.8ghz
And your front side bus is 100
That would make
100(F.S.B) x 28=2800 Mhz(2.8ghz)
So basically for starters we will learn how to overclock by raising the multiplier only
So basically You keep on raising the multiplier by .5
Then boot and use a stress testing program called Prime95 or AIDA or intelburntest.You check your temperature using any of the free softwares out there like hwmonitor and make sure you keep under the maximum temperature stated by the manufacter(intel in your case) for your cpu.I'm talking about your cpu's temperature.
After increasing a few multipliers you'll notice you can't boot into windows,That's because your cpu is not getting enough *Core Voltage* to run that multiplier,Oh one thing I forgot to mention is that you need to find the default CORE VOLTAGE for your cpu and set it too that,when you can't raise the multiplier anymore and your temperatures are still well within the safe limit you increase the voltage ONE INCREAMENT at a time.Do not increase by more than one increament at a time.Try to see if you can access windows with the boosted voltage.Then stress test again,Now you gotta find the maximum core voltage on your cpu by looking on intel's site.And make sure you stay within the safe temperature limit and voltage limit as stated by the manufactor.Now there are some cases where you're cpu is locked and cannot raise its
multiplier.
That's where Front Side Bus comes in hand,If you remember the formula I gave you its F.S.Bx Multiplier=Core Speed so by raising the Front side bus you raise the total core speed.Although the thing with F.S.B though is it increases most of your components speed on your motherboard,You may think that's great easy overclocking.But you are wrong,as let's say your cpu is well within its overclocking limit but if you keep on raising your F.S.B your RAM or your Northbridge(more advanced stuff) may reach its limit,This will cause stability issue causing you to get Blue screen of death.So yeah this is 101 on overclocking for newbies
P.S-Make sure to keep an eye on the temperature of your motherboard and it's VRM as most of the cheap motherboards cannot handle the overclocking the cpu can take and will most like fry if not taken into deep consideration.And you'll notice with your stock intel cooler you will only be able to get around 100-300 mhz overclock whereas if you had an aftermarket cooling you would be overclock much higher due to having a much much better temperature.
