What is overclocking in CPU.....?

Answer 1

Overclocking is the process of running a computer component at a higher clock rate (more clock cycles per second) than it was designed for or was specified by the manufacturer, usually practiced by enthusiasts seeking an increase in the performance of their computers. Some purchase low-end computer components which they then overclock to higher clock rates, or overclock high-end components to attain levels of performance beyond the specified values. Others overclock outdated components to keep pace with new system requirements, rather than purchasing new hardware



The primary benefit of overclocking is additional computer performance without the increased cost. Most individuals who overclock their system either want to try and produce the fastest desktop system possible or to extend their computer power on a limited budget. In some cases, individuals are able to boost their system performance 25% or more! For example, a person may buy something like an AMD 2500+ and through careful overclocking end up with a processor that runs at the equivalent processing power as a AMD 3000+, but at a greatly reduced cost.



There are drawbacks to overclocking a computer system. The biggest drawback to overclocking a computer part is that you are voiding any warranty provided by the manufacturer because it is not running within its rated specification. Overclocked parts that are pushed to their limits also tend to have a reduced functional lifespan or even worse, if improperly done, can be destroyed completely. For that reason, all overclocking guides on the net will have a disclaimer warning individuals of these facts before telling you the steps to overclocking.

Answer 2

confident, through fact once you overclock your expanding the voltage, and that CPU can in undemanding terms cope with lots and gets warmer than what it particularly is meant to and reason issues. in case your going to overclock, get a liquid cooling gadget, then it particularly is not AS risky.

Answer 3

Overclocking is the process of pushing to CPU to perform outside it's rated frequency.

This can be achieved by manipulating the FSB (Front Side Bus) and the CPU clock multiplier. When overclocking, you also have to push more power into the processor in order to function properly. This is achieved by increasing various voltage levels (usually just the north-bridge voltage and the CPU voltage). Failure to provide the CPU with enough power



For example:

My processor runs (stock) at 2.66GHz. My processor achieves this speed by multiplying the front side bus (266MHz) by the clock multiplier (x10). 266MHz x 10 = 2660MHz = 2.66GHz.

I overclocked my processor to run at 3.4GHz by increasing the front side bus to 425MHz and LOWERING the multiplier to 8. 425MHz x 8 = 3400MHz = 3.4GHz.



For my processor to run stable I had to increase the CPU voltage. My processor runs at a stock CPU voltage of 1.27v. For my processor to run stable I had to push more juice into the processor; I needed it to run at 1.42v. I reached this conclusion by using pure trial and error and a lot of testing using a program called Prime95**. This added power causes added heat. Those extra 0.15v that I set the power supply to supply to the processor created A LOT MORE HEAT. This heat was too much for my heatsink fan and I was forced to choose a much more optimal cooling solution.



All processors overclock differently, even if you're comparing two of the exact same model CPUs.

I can't push my processor too much further than 3.4GHz (on air cooling; I may be able to do so with water cooling solutions) but someone with the same processor as me (heck, they may even have the EXACT same hardware as me right down to the same BIOS version) and may be able to push the CPU to 4GHz on air cooling. ALL chips (processors) vary in how well the overclock. I must note that overclocking ANY COMPONENT decreases it's life span, because it's not meant to run at the speed it's being forced to run at.



Many people overclock to save money. For example, The difference between some of the Phenom II X4 processors (made by AMD) differ only in clock speed. Some people will purchase a slower, cheaper model and overclock it to perform on par or BETTER than the much more expensive models.





**Prime95 pushes the CPU to its limits. All cores are pushed to 100%, testing various complex calculations, involving mersenne prime numbers. Basically, it tests to see if the processor can perform complex mathmatical computations. If the test expects 2^4 to equal 16, and the processor returns the answer as 15, whichever core processed that calculation gets shut down, and the CPU fails the test. While this doesn't seem too bad, it is very bad. Errors such as this could cause the computer to crash, and often. If it passes for an extended period of time, it's deemed "stable".

Answer 4

Nothing that would do you any good if you're to stupid to read up on what overclocking is

Answer 5

Overclocking is pushing it beyond what the specs say. OC can be good and bad



Good as in getting more out of a low budget CPU or GPU to get more performence/FPS so on so on

Bad as in risk of over heating/frying a component, wearing it out faster. Theres really alot to it. Dont over clock without reading and studying it. Go google overclocking if you really want detailed info

Answer 6

overclocking is when you set the wattage higher then default settings which cause it to run faster because it has more fuel to consume, I would not suggest overclocking a base computer that has been purchased from a retailer. this is because when you overclock a cpu it runs hotter and if not properly cooled a cpu will die and now your stuck with a computer that no longer works

Answer 7

just think of your cpu like someone on a treadmill, they have their own pace. However overclock = make them run faster but get hotter (potentially).

Answer 8

Like putting a turbo in a car

Answer 9

Wow. A lot to say.

Well, "overclocking" means to run the cpu frequency at a higher rate than what was determined by factory default settings. Hypothetically, a cpu runs at 2.4 GH(Giga hertz), now, because you have a tower pc, a cpu heat-dissipation fan or liquid cooling, you can run the "clock" of the cpu at a higher frequency than default; 2.4GH to 3GH. this is achieved by altering the BIOS, but only should be attempted if you have already installed an additional aforementioned fan or liquid cooler onto the heat sink of your cpu, thermal paste required. The two, primary issues with overclocking limits are temperature and voltage. You don't want your cpu to idle over 40 C and you don't want it to run on "full load"- maximum capacity, like top speed in a car- over 80-90 C; neither do you want your pc to give volts to your cpu more than necessary, lest your cpu die out early. You can record results using CPU-Z and overclock using this manual:

Happy overclocking.
