Overclocking

Posted by dogman1234 on January 20, 2011


There are many ways to increase your computers performance. One of them is adding more components, changing to new components, or overclocking. Overclocking, by definition, is the process of increasing ones processor clock generator to achieve a higher cycle rating for faster processing. Basically, make your CPU run faster. The basic understanding of overclocking is the essential increase of information travel to get  the Input/Output system to move along. Example: If traffic is moving 25 mile per hour through a tunnel, how much traffic could you get through a two-way? Not much. Now, if one increases the speed, the traffic density will decrease and traffic will increase THROUGH the tunnel. That is the idea of overclocking. Overclocking takes the information and speeds it up to get more out than let is rest inside the CPU. How does one go to overclocking a CPU? Well, it is not that hard. let us take a look at what can be done to increase your CPU speed. First, the understanding of where, what and how:

Where: To overclock, may reside to the BIOS,( or Basic input/Output System). An alternative to BIOS is UEFI,9 or Unified Extensible Firmware Interface. This is just a graphic version of BIOS). the BIOS will allow you to change features of the computer and its parts so that better communication is achieved. Altering the features will alter the systems behavior, either good or bad. That is why overclocking is somewhat controversial.

What: What is needed to overclock. Well, a computer,( no, duh). The most needed is the hardware, and firmware,( BIOS). There are things to watch out for in the Processor section of the BIOS.

Base Clock Frequency, Core Voltage, Voltage, Temperature, Multiplier, speed. Let us start with Base Clock. BLKfreq, or base frequency, is the standard frequency of operation.Some may call it the Front Side Bus, others the Quick-Path Interconnect.  These are not it. it is actually the Multiplier. It is what allows a specific frequency to be achieved for the CPU. Here is where Frequency comes in place. It is timed at the Megahertz level. Some CPU’s come standard with a 133 Front Side Bus frequency. To manage a stable CPU, electricity must flow through the semiconductor. Vcore, or voltage, is applied to the CPU to make the clock speed become more stable and the unit will not be disoriented.

How: Here is where the fun begins. Start by entering your BIOS, go to the CPU configuration center. Now look at what you have as a stable unit right now. Adjust the FSB from 133 to 140 MHz. Increase voltage by .0125v. Reset the computer. Now, enter the BIOS again and increase FSB form 140 to 150 MHz. increase voltage by .0125v each time. If you chose to increase the Multiplier as well, you must increase the FSB by 5 MHz along with +x1 multi PLUS an increase of .0250V.

That is the idea. There are good tutorials to specific CPU’s tailored to the enthusiasts mind. Go to the listed sites to your right and search. thank You, and have a great day…and a happy overclocking as well.

    There is one additional thing I think is worth mentioning in regards to Overclocking. As a computer service provider myself, I tell clients Overclocking a computer is *likely* to reduce its lifespan due to added wear and tear on the components. Now, whether you agree or disagree with this statement is not important, but adding a disclaimer such as, “Overclocking a computer *MAY* result in additional wear and tear on motherboard or other system components, and users assume any and all additional risk associated with this practice.” is recommended. The last thing any of us wants is someone coming along with a lawsuit later stating “(X) told me is was ‘safe’ to Overclock my computers and now my AutoCAD business has fifteen dead machines in two weeks time.”

    Every system is designed with specific tolerances and an estimated time before failure. Manufacturers are well aware of this and predicting the future failure rate of sold systems actually HELPS them project future manufacturing demands. So, the more customers that Overclock their computers the more likey they are to accelerate the demand for replacement machines ahead of its original curve.

    It is far better to buy a system capable of running the number of processes desired OUT OF THE BOX and hoping it actually meets the manufacturer’s original lifespan estimates — unless you have the money to replace a system or its components whenever you want.

      I will actually get into overclocking this was just the basic idea of what overclocking is. It never said that its safe where do you read that ? And overclocking is fine as long as you have good cooling and an aftermarket heatsink, it wont decrease your cpu lifetime by much. that depends on how much voltage you add to keep your cpu stable, Say your cpu is 2.4ghz at 1.3v say you can go up to 2.8ghz on the same voltage. This means that your cpu lifetime wont be decreased. As its still on stock voltage.

      Thanks for brining it up though but i will get more in depth about it sometime soon.

    Hello guys,

    I will try to put emphasis in the thread about the effects of overclocking. We will see to it that everything is in order and that all posts are neatly written.

    Thanks guys! Certainly this is not the first helpful site on the topic of system performance and extreme tuning, and my bet is that it will not be the last. I think the format of this site is very good and definitely hope you will continue working on it.

    One possible way to improve the article might be to take a complex reference material such as Wikipedia’s “CPU Core Voltage” article and ‘decode’ it into everyday English. If I am reading the article correctly, the distance between the two “Terminals” in a Field-Effect Transistor (or “FET”) is growing ever smaller with improvements in CPU manufacturing technology. If we think of this gap as being similar to the gap in an automotive sparkplug, the voltage builds up and “jumps” the gap at certain intervals when the impendence (or resistence) to current flow is overcom. Certainly in semiconductor terms the flow of current is “controlled” through other means, but the principal is similar enough that I can use it to illustrate my point.

    In any electrical circuit the “wear and tear” occurs when current flows and although this wear is measured in millions or billions of signal pulses through the circuitry, it still is finite (or of fixed lifespan over a specific time). Therefore, if we increase the frequency with which the “management pulses” occur, it is in effect like downshifting a manual tranmission is a car and increasing the Revolutions Per Minute (or “RPM”). Yes, the car runs faster in this configuration, but the mechanical strain placed on its engine components and drive train (or “Transmission”) probably increases. There is also the idea that intra-circuit cooling, or the cooling happening deep inside the CPU, is not going to have as much time to take place between pulses. All the CPU cooling fans and gadgets on the market move heat away from the surface of the CPU chip, but there are none I am aware of which can improve cooling within the chip itself.

    If we think of the circuitry of the CPU as the internal parts of an automative engine, then these are the Pistons, Rods, Cylinder Heads and CAM Shaft (and so on). While the cooling mechanisims are the Radiator and Cooling Anti-freeze fooling through various channels surrounding the engine. In fact, the cooling system of most automative engines is probably more efficient at removing heat from an engine block than the present air (or liquid) cooling systems of CPUs.

    Gamers and graphics professionals can certainly Overclock their CPUs, but my point is that each of these audiences should also be aware of the “potential” downside of this practice.

    I would love to know more about Overclocking and practice it on a couple of systems I do not need to rely upon each day, so until that time I will rely on your expertise and GREAT PHOTOS to understand this subject. Keep up the geat work!

      Hey good example and comparison but in my opinion the wear and tear is very minimal as long as the cpu does not get to hot. Most people wont even reach the end of their cpus lifetime as everyone updates to new parts every 3 to 5 years.

      Thanks again and hope to see you around.
