Understanding Basics of Overclocking

Introduction to Overclocking

Long term that comes to your mind is "What happens in Overclocking? Is this dangerous for the equipments?" So many questions which we used to meet on our forum.

You should know that any changes in your PC can make it unstable,specially change in Temperature, because there is a close relationship between the frequency and operating temperature of a component.

In this last sentence that you should understand that all the components are clocked should be at a lower frequency than they could reach a maximum. In the best cases you can control all the change. You can make a use of specialized software as Rivatuner tool for your graphics card, and so on.

Overclocking does not destroy the equipment, it is near to impossible , happens really rare. In the worst case, but rather your operating system may suffer from the instability of your configuration for your hardware working with your OS.

Practiced so extreme (forced cooling) as we like to do here, overclocking a lot more risks, playing with the limits is still unreasonable, but so fun. In any case we hope that pleasure and performance are words you’ll hear. 

Most of the time you get higher frequencies that are not available officially, and performance that come with it. Interesting isn’t it?

The overclock is not only the increasing frequency of operation, we would rather talk about adjusting the frequency working conditions for components. Users who overclock their components mainly focus their efforts on processors, video cards, motherboard chipsets, and Random Access Memory (RAM). It is done through manipulating the CPU multiplier and the motherboard’s front side bus (FSB) speed until a maximum stable operating frequency is reached.

Overclocking is a technique which increases the clock speed (over-clocking) of the original processor. Like most things, especially electronics, have a small range of tolerance, for example, any appliance that operates on 220v, it can also operate at 230v or 210v depending on the tolerance that the manufacturer gives you. The processors are also designed with a range of tolerance (elgunos processor is in little as in the K5 and others is very high, as in the Celeron). This tolerance is very largely in the heat. Suppose a processor running at 35 ° C in extreme cases such as summer or playing the processor must operate stable at 50 ° C, then do not leave it to its maximum capacity or speed to avoid overheating, but a little less so if we succeeded in cooling the processor can either increase the speed without affecting the estabildad. Sometimes you can be stable with the original cooling.

How to do Overclocking?

First of all there is to know how to measure the speed of the processor. There are two speeds, the internal and external processor or bus speed . Bus speed is the speed at which the processor communicates with the various components. The internal speed is the speed at which the processor works, and makes load. The speed is known commercially and is the internal speed is calculated as follows:

Frontside Bus speed * multiplier = processor speed
The bus speeds most important official in the market are 66, 100 and 133 mhz. For example, a Celeron 366 is: 66 * 5.5 = 363 (commercially 366) is a Pentium II 450: 100 * 4.5 = 450 and a Pentium III 533 is: 133 * 4 = 532. Multipliers are usually integers and decimals 0.5 (2.5, 3.5, etc. ..) multipliers depend on the mother trjeta (some are from 1.5 to 5.5 and from 3.5 to 8). The bus speed is also dependent on the motherboard (some are 1 or 2 and more than 20). The most common are: 66, 75, 83, 95, 100, 112, 124 and 133.

  • How to Stabilize it ?
    Of course there is always a limit on the processor becomes unusable and can not do anything, but sometimes you can stabilize. First of all with good cooling and increasing the voltage of the second processor. Range is between 15% and 20% (depending on the original voltage). For example the maximum 2.2 to 2.6 or 2.7 may be 3.2 to 2.8, etc. .. The main drawback with this technique is that by raising the voltage also increases the heat and without a good cooling something worse may happen.

    As an overclocked component operates outside of the manufacturer’s recommended operating conditions, it may function incorrectly, leading to system instability. Another risk is silent data corruption by undetected errors. Such failures might never be correctly diagnosed and may instead be incorrectly attributed to software bugs in applications or the operating system. Overclocked use may permanently damage components enough to cause them to misbehave (even under normal operating conditions) without becoming totally unusable.

    Heat is a major enemy of any electronic device, so we should look to eliminate as much as possible in our system. There are techniques to increase the heat dissipation, but require knowledge, money and sometimes imagination.

  • The heatsink
  • The fan
  • The fan / heatsink
  • Peltier units
  • Micro cooling
  • Graphics card cooling
  • Cooling box
  • The most common cooling system in computers is the fan / heatsink.

We must first cool the micro-component in question, although the graphics card can also be quite warm. To this end, a heat sink on the micro, which absorbs heat from its surface and eject it, aided by a fan to avoid the pond that warm air near the micro. The greater the heatsink and fan, best. There are fans to control the speed of rotation or the temperature of the heatsink that are in contact, really important.

For cooling, the ideal is to have a fan , which brings cold air. In a normal power supply tends to draw the hot air, but is not normally a fan of entry. So a fan will be convenient to purchase and install on the front of our computer, where generally there are some holes already prepared for a 8×8 cm fan.

In any case, do not forget two points: one, that hot air rises, so the air flow must be above (never below the entry of cold air), and two, there are few schemes as effective and Cheap as opening the computer case. It is not very aesthetic, but it works very well.

We must take into account that by increasing the clock frequency also increases energy consumption, and that fans can add to exceed the capacity of the power supply.

Advantages of Overclocking:
One of the main advantages of a computer overclocking is increasing the speed. While the time is near and programs are added, the speed of a computer is reduced. Even a brand new computer could always benefit from the ability to run faster. With a click of your mouse, launch programs without much delay and while typing the letters appear immediately. For a slower computer, it would be small but significant delay especially when you’re using software or playing games.

Another benefit of overclocking is that you will see the total increase in performance. The programs will begin to function more smoothly than before and the time of shipment will be declined. If everything goes great for overclocking process, your computer crashes and programs will be less susceptible.

To take advantage of the increasing speed and performance within your system, there is another particular advantage that gamers will enjoy.

When you overclock your system, you also make the video cards. These cards are projected graphics to your screen. For gamers, this is an important advantage because it will transform the game graphics and gently increase the frame rate. The delay of the system that often angered gamers will experience the best fallen and the game will be achievable.

Speaking of the advantages of overclocking a computer, we must mention the financial benefit. This is probably one of the main reasons people select to go this route with the updating of your machine. Instead of buying new components such as a faster processor or more RAM, a person can easily change the settings to make the components and function at its highest level with little or no cost associated. Depending on your current components and their settings, sometimes you can even overclock the component at a rate higher than the improvements currently sold in stores. This is a good way to get tomorrow’s technology today.

Disadvantages of Overclocking:
One of the main risks associated with overclocking your computer is warming. Since overclocking means you will run the components at a rate much higher than anticipated, the cooling system installed inside the computer can not handle higher temperatures. This leads to overheating and can cause serious damage to your system.

Another risk that is associated with overclocking is instability within the system. It is possible that the wind can really overclock certain components and make the operation of the stop. One example is the sound card. After overclocking, your sound card may stop working. Also, you can see an increase in crashes and the computer programs that are insensitive.

Rule number one with overclocking your computer is that if you are not willing to risk losing your computer to severe damage, it does not overclock. Whenever you alter the settings on your computer, you’re taking a risk and that risk can end up being fatal to your computer.

In the review, although there are many risks involved with overclocking a computer, easily outweigh the benefits. The power to take a computer and change the setting to a point where your system is working at full potential it provides is a great feeling of achievement and can boost the ego of a person within seconds.
