What is

Overclocking is a cool way of making your CPU,
video card (monitor card), 3D accelerator and some other kinds of hardware run
faster and give better performance for free! (Intel's worst nightmare!
During this tutorial I will teach you how to overclock your
CPU, but you can use this information to overclock other kinds of hardware on
your PC.
Now, your CPU speed is based on two factors - your BUS(2) speed and
your clock speed (mine is 1 second per second... just kidding. I don't mean a
standard clock, like one you can tell time out of. Read on and you'll
Example: The BUS speed on older computers (let's take a Pentium
I 166MHZ(3) as an example) is about 66MHZ. 166, the CPU speed, divided by 66,
the BUS speed, gives you about 2.5, meaning your clock speed is about
Simple, huh? BUS speed X clock speed = CPU speed.

what exactly is overclocking and how do I do it?


  1. The little booklet you were supposed to received together with your CPU.

  2. A screwdriver (better be a Philips screwdriver).

  3. A metal plier with a rubber/plastic handle or a bunch of fingers (better be
    your fingers... oh, and when I said a bunch of fingers, I've meant at least 5,
    all of them attached to a living hand (better be yours). Undeads are also

  4. A calculator / a brain.
A) Open your computer using your trusty
B) Look at the little booklet you have and find the part about
the jumpers(4) board and read.
C) Use the plier or the fingers to change the
jumpers array so you will receive the clock speed you are interested in. Oh
yeah, and try not to step on your CMOS chip(5) or on your Cache chip(6).

Note: newer CPUs are "Clock Locked", meaning you cannot change their
clock speed, but you can still change their BUS speed... ;)
Changing the BUS
speed is similar to changing the clock speed (read the part on your booklet
about the jumpers).

How Dangerous is This Whole

Well, you CAN fry your modem, but it all depends on you.
you screw up and step on things, spill coffee over your computer or overclock
your CPU too much (see Advanced Tips), don't come back crying to me.

Possible Side Effects:

  1. Your computer won't start: this probably means you have overclocked your
    computer too much. Lower your CPU speed a bit and then try again.
  2. Your OS won't start (or crash very frequently) or your computer will reboot
    itself randomly etc': open your computer, find the jumper that changes the CPU
    Voltage (the CPU Voltage is usually something that fits into this pattern: 2.x,
    when x can be any number) and increase the voltage a bit on every
    Remember to increase your CPU Voltage as little as you can. The maximum
    is "VOLT 2.30". If your computer still gives you problems then do a little less
    overclocking and it should be fine.

  3. Overclocking your CPU might increase it's temperature and decrease it's life
    span. Don't worry about that, experts claim that during the year 2,000 we will
    replace our CPU once every 6 months and this will become more frequent during
    the years so you've got nothing to worry about.

How to Avoid
these Side Effects:

  1. Attach another fan or a "Heat Sink" to your CPU. It shouldn't cost much (a
    couple of bucks, maybe) and the outcomes would amaze you (For example: using a
    device that cools your CPU to -20 Celsius degrees you can turn a Celeron 300A
    into a 633MHZ CPU)

  2. Place your computer where you won't block it's air ways.

  3. There are programs like CPUIdle (URL(7) to download: http://www.geocities.com/SiliconValley/Monitor/6990/cpuidle.zip)
    that can shut down your CPU while it's not in use. These actions can decrease
    the temperature of your CPU, and it can even increase your CPU's life span.
    Note: CPUIdle only works on Windows, since it is "Built-In" on other OSs (see
    CPUIdle's documentations).

Statistically Speaking, How Safe
is this?

Very safe. Out of tens of thousands of overclockers in the
world, only a very few got some of their hardware fried up (and who says it's
because of the overclocking anyway?), and those guys didn't listen to the safety
warnings (they overclocked their CPU too much, increased the CPU Voltage too
much etc').

Is it Worth the Trouble?
DUH!!! Of course
it is! Do the math yourself.

How do I Overclock My 3D

Overclocking 3D accelerators is pretty much like
overclocking CPUs, only you have to take one factor into consideration... your
CPU speed.
You see, the speed your 3D accelerator works depends on your CPU.
The 3D accelerator cannot work faster than the CPU, since some vital 3D
calculations are done by it, hence the accelerator cannot continue without these
If your CPU's speed is lower than 400MHZ, I advise you not to
overclock your 3D accelerator. Go overclock your CPU and then overclock your 3D
card!! HAHAHA!!
