Introduction
When “fast is not enough” gamers and hobbyists find and devise new and intriguing ways of taking their hardware to the max. Even with these fastest chips available, most users still demand more and say that the speed from even the fastest chips aren’t fast enough, or they just blatantly just want more. This is where overclocking comes into the equation; by which users make their processor run faster than the default recommended speed setting. Overclocking has become common with all of the newest hardware devices having the ability to reach overclocked speeds of over 50%.
Q. If a processor can achieve higher speeds why don’t manufactures increase them?
A. To regulate the market, making one processor that can range from 1.6 to 2.4 and just regulate speed is easier than making a different one for each speed.
Things you should know
The following you should know before and to successfully overclock a your AMD or Pentium: an overclockable processor, an overclocking friendly motherboard, and a plan for a great thermal solutions including heat sink and extra system cooling fans. Check your system for extra fan locations, later in this text will be detailed info on how to configure them.
• If you plan to overclock you system then be sure to select your hardware wisely. There are always overclocking opportunities. Intel and AMD produce processors that are overclockable.
• Some motherboards are more overclocking-friendly than the others, I suggest Asus or Epox. Select a motherboard that has good reviews, don’t experiment or settle for one that’s not reputable because the motherboard is the heart of you overclocking project. Do you homework!
• Once you’ve become an experienced overclocker, you know to keep the processor and the entire system cool to ensure stability, select a case that can handle many fans for optimal airflow. Your number one enemy for overclocking is heat.
o Add additional system coolers in the front and back of the case to generate an air flow pattern coming in from the front and exiting at the back.
o Make sure the cooling fans for the power supply sucks hot air out of your system box.
o Use thermal compound (do not substitute) between a good and strong heat sink and the processor to ensure great thermal contact and thus optimal heat dissipation.
What are the benefits of Overclocking?
• The increased performance with minimum cost
• Satisfaction from achieving it, then later tweaking it.
*What are the risks of Overclocking?
• Overclocking may void your system warranty.
• Overclocking may reduce the life-time of your system.
• Overclocking may cause system less stable. If you find your system unstable at higher speeds, proper testing is the key to a successful overclock.
What is clock speed for of processor?
The clock speed of a processor is the main factor that determines the computing power of a computer, measured in MHz or GHz. To better understand the concept, imagine your car drives at fixed speed of 1 to 60 mph, although the optimal speed is 50, nothing prevents it from going faster or slower. You want to run at higher speeds only at favorable conditions.
How CPU manufacturers determine the clock speed of a processor?
The manufacturer decides on what speed to stamp on the processor based on the following factors:
• Core, design, and capabilities of the processor itself.
• The thermal stability and characteristics of the processor.
• The most advantageous market conditions.
From the above it is clear that given the right conditions, a processor can be either underclocked or overclocked. An 900MHz processor can be overclocked to run at 800 or 500MHz as long as the motherboard allows, or overclocking to 1200MHz.
How to set the clock speed of a processor?
The actual clock speed of a processor is set by the motherboard. There are two ways to do this.
Hardware jumpers. You can change the jumpers to get different combinations of basic BUS speeds and multipliers. This method is used for most brands of motherboards. It is however inconvenient since you need to actually open the case to access the motherboard and to know what your doing. So if your looking for a motherboard that overclocks easily, look for “jumper free” overclockable motherboards.
With software "jumpers" or “jumper free” motherboards, you change the clock speeds (and the core voltage) of a processor using software embedded in the motherboard BIOS. Most overclockers like this option.
What is Overclocking?
This is the process of running the device faster than it is specified to do. Overclocking is an old process that just recently has gone mainstream. Overclocks can range in the 30-50% range with some creative cooling, if not air cooled then liquid (Water or Nitrogen). Overclocking achieved by increasing the frequency at which the processor is multiplied or bus speed.
With a successful overclock, the system will run stable and exactly the same as it did at the default factory set frequency, just faster. This often requires more cooling than stock and increasing voltage on processors improving the speed of devices, internal and external, and performance improves in accordance to how much the device is overclocked. If not properly overclocked, usually from overclocking too much, performance can actually degrade, as the processor or is over stressed beyond optimal frequency settings.
Overclocking generally refers to running your CPU, and these days your video card too, at higher internal CPU clock and bus speeds than the manufacturer's specs for achieving better system performance at little or no cost. In the past, overclocking was simply changing your motherboard's settings for the next higher CPU Multiplier. It's not as simple anymore, since both Intel and AMD have locked the multipliers in their CPU's. As a result, in today's world the bus speed is usually the only easy way to overclock and achieve CPU speeds that don't officially exist. Bus speed, as opposed to CPU overclocking changes your whole motherboard's BUS, affecting PCI, AGP (with all the components attached to them) as well as Memory speed, so in effect you are overclocking everything! Because of the fact you are overclocking your whole system and every component connected to it, one of the necessary requirements is to have good quality components. You have a better chance of reaching higher speeds and still running a stable system with good quality brand name components instead of cheap hardware. Some brands/models of hardware overclock better then others, some don't overclock very well at all, so it's a good idea to already have a rock stable system with good quality hardware before you attempt overclocking, since overclocking essentially pushes your system beyond the manufacturer's specs, adding heat to the equation.
How to Overclock
Overclocking is accomplished by adjusting the frequency of either the CPU multiplier or FSB (front side bus) speed in the Bios of the motherboard. All common day processors have a multiplier locked, meaning that the rate at which the speed is multiplied by the front side bus is not adjustable. Therefore to overclock these processors one must adjust the bus speed.
FSB speeds are an important aspect of Overclocking because it influences the speed at which all devices connected to the motherboard operate. There are usually three default front side bus settings, 66MHz, 100MHz, and 133MHz. The slowest of the three, 66MHz, and 133MHz the highest, was used by Pentium II processors slower than 350MHz and all previous processors starting with the original Pentium line. Today’s Celerons run at this 100MHz FSB, which is one reason why the Celeron lags so much behind its older Pentium III brother. 133MHz FSB is which PIII processors run today, P4 processors depending on the level you have, can range from 400MHz to even 533MHz and up operate at this frequency.
Pentium IV processors can be overclocked with 103MHz and 112MHz front side bus speeds easily. Of course, anyone can overclock this easily, but most often than not, something else will be required to get an overclock to be successful. More often than not, voltage adjustment will be required. Increasing the amount of power that the processor receives will give it the little extra power to get the processor to be successfully overclocked. Remember that when overclocking, always move up in the smallest increments allowable. Doing otherwise could be harmful for the system
