How Understanding to Overclocking

The word overclock may be a foreign language for a beginner who is interested in the field of hardware . But for those who have advanced the field of hardwawe , the word is a word used raw and in their daily lives .Language overclock composed of
two words over and that means the clock setup mainboard and a processor clock for VGA . Overclock said connoted by making computers faster .

Either when starting the hobbiest to overclock . It is estimated overclock already started in 1985 . If not mistaken , the first computer sold are the type XT PC with Intel -type processors ( 8088 ) and made ​​faster work of the NEC V20 processor . Understandably speed on the PC XT computer beforehand incredible slowness . Never mind the word Linux or Windows systems . We know when it was just the IBM PC - DOS as the operating system of a computer . DOS diskette shaped only been able to be used as storage on a computer including the operating system . In the years that not many people know about such as the type of hard disk or memory . Hardware is still very expensive and simple . Never even heard the word giga today. Memory is still a few Kilobytes , the first very large hard drive with a few tens of megabytes

Overclock began when the Pentium processor and 486 DX Classic first . But spurring processor can only be done with jumpers on the mainboard . Eg 166Mhz Pentium 200MHz speed dijumper be , little difference between 166Mhz and 200MHz . But good enough for speed this year .

Hectic overclockers began in 1997 when Intel issued a speed 300Mhz Celeron processor types with type 1 slot and driven into a crowded crowded 450MHz . When it appeared the overclockers who started spur processor until the last line .

Taiwanese company when it has mastered the field of hardware makes the mainboard with the option that can be set up by the user . The emergence of the mainboard to setup Abit BIOS and mainboard via jumperless . The first announced Abit mainboard with minimal jumper and the user can perform the setup in the BIOS for the processor speed .

WHAT IS THE REAL PURPOSE overclock ?

The main goal is to overclock a processor spur VGA and CPU in order to work faster .

But this time to the existing technology , enabling a person to have the convenience of making computer with overclock . For example, someone wants to spur faster computer processors work with lower to match the computer has a faster processor and expensive . For example, using the processor for $ 1 million but was able to have a speed that is almost or exceed more expensive computers with processors

There is also a special purpose that became a trend after 2000 . For example, for gaming applications . With the overclock , a computer will be faster and more convenient to enjoy. With overclock all devices will increase . It is this last function is the most general purpose use . Due to the availability of additional devices almost everything is available , and supported by the mainboard companies to enter the BIOS overclock system . Unfortunately , when it has not all been perfect development . Because of the limited devices such as memory , motherboards and heatsinks are not as complete as it is today.

HOW DO overclock ?

Actually overclock the CPU clock speed setup in the BIOS . When a processor with a speed of 1.6GHz with 100MHz bus , meaning that the processor runs at a speed 16X100Mhz will produce 1600Mhz or 1.6GHz processor speed . By changing buses at the BIOS option instance from 100MHz 133MHz then the computer will be working with a speed of 2.1GHz or 2.1Ghz or 16X133Mhz with 2.128Mhz results . Is so easy to overclock . Yes , only in this way can be driven computer and how easily someone overclocking .

HOW EXPENSIVE THAN THE COST overclock ?

Costs can vary overclock . When you overclock a computer that is not too high , for example by accelerating the rate of the processor to 10 % or 20 % faster . Maybe you do not need the extra cost . The only changes made ​​in the BIOS alone .

Example you are using 1.6GHz processor , then spurred into 2.1Ghz . With standard heat sink , is still positioned at a safe speed for the computer and can be done easily .

But when done overclock quite high , above 25 % for example , will generally occur in constraints appear hot processor . Because the design of the processor heatsink cooler made ​​standard as limited to a particular speed . Constraints on the thermal processor can be improved by converting non standard heatsink . With non- standard then the processor heatsink avoid hang or malfunction due to overheating work . Or assisted on the air circulation inside the computer to improve the cooling system .

Why heat a scourge of activities overclock . With increased speed , the impact will make the processor gets hot .

Then where the level of activity overclock expensiveness . When you overclock the processor alone , without any other fixing devices . It can be said to be cheap . But if you wish to optimize all existing devices , including memory , mainboard premium , top-end VGA , power supply , cooling and even a special case designed for overclocking . That is where the value is expensive to be provided . Because of a special device that is provided does have its own advantages .

Having a computer with the most optimal level of hardware is almost the same as buying a PC at a price of 2 PCs . Example, first there are a beginner wanting a good conditioner for the computer because it has been overclocked . To save him buy 7.200RPM 80mm fan speed will be cheaper than buying a good heatsink but more expensive . A few days later , he returned 7.200RPM change their heatsink with a new heatsink . It is said , when paired fan inside the case turned out to make her come around the table to vibrate .

WHAT YOU NEED TO DO TO DO overclock ?

Easy to make in order to overclock the processor , but the impact is wide enough for other hardware . When speaking on the current computer , overclock will affect the system hardware like I / O , VGA and others .

A few MHz overclock the processor will also boost the performance of other parts such as memory , PCIe , PCI and AGP clock . This means that when the processor with 100MHz bus speed driven into 120MHz ( 20 % ) , then other hardware clock speed also increases . Similarly, the memory speed will be encouraged to follow the processor speed is about 20 % .

Many errors occur for beginners because it is not too familiar with the calculations , as well as the limitations of the hardware capabilities . For that we share of each hardware associated with each other because it will directly affected when driven on a standard processor .

Spur overclock PROCESSOR WITH THE IMPORTANT THING CONTAINED 3 .

1 . Processor has a certain speed limit , the higher the more hot and unstable . Facing heat can only be faced with a good cooling system . Change their particular type of cooling will keep success when overclocking .

2 . The higher the multiplier a processor will increasingly unstable . Generally, those who want to overclock to take the initiative by buying low bermultiplier processor . With a low multiplier , then the speed of the processor has a higher persentas plus cheaper . Suppose you use a 2.4Ghz processor with 200MHz 12X multiplier will easily be driven into 3Gz with 250MHz bus dann an increase of 25% . Compared with a 3GHz processor you are using the bus 200MHz and 200MHz 15X multiplier which requires working at 3.75Ghz with 250MHz bus would be hard to steady work

3 . Power for processor power . We are familiar with overvoltage . By adding voltage to the processor will maintain the stability of the computer . If overclocking is done at a reasonable limit , overvoltage rarely done . But at a fairly extreme overclock , overvoltage generally be a last resort taken . The impact back to the first point ie the heat of the processor . Why overvoltage done . The faster the processor works , the greater the power or the power is needed . By increasing the power supply to the processor with the increase in voltage or overvoltage will provide sufficient power when the processor works on standard speed . To increase the power to the processor , there is an option in the BIOS setup vcore . Figures Vcore processor is what is played in order to become more stable

IMPACT ON - CHIP SET STABILITY AND OTHER HARDWARE .

After discussing the overclocked processor constraints , we again see the bottom of the bus clock to the computer system . Looking from the mainboard , there is a division of the same speed that the work of each of each synchronous hardware .

Seeing the bus division you can analyze . When a computer with a processor speed of 100Mhz on the external bus , and driven into 120MHz . The impact calculation on device PCIe clock , AGP and ISA buses also increased 20 % faster . Sample only when an AGP VGA with 66Mhz bus , the speed of the chip - set which is driven 20 % alone will force the VGA working on 80MHz speed . That is going to be difficult to make the VGA remained stable when playing games . Or you are using a SATA hard drive types that are sensitive to change , when doing overclock may cause failure of the hard drive to work .

Before the company makes the option lock mainboard PCIe / AGP and PCI , the easiest way is to find a safe spot on the internal clock . When someone overclock , 20 % may actually make the hardware is not stable . However, increasing the speed to overclock 30 % instead of hardware to run normally . The point of 30 % is a safe point taken the overclock . The safe point calculation is different both in kind of existing processors .

Constraints on increasing the speed of the chip - set with overclocking , this time is not a problem . Several companies have been designing mainboard so that the computer works more stable with the addition of a new option to lock from the hardware clock . This option serves as a lock so that the clock of the other hardware does not go up following the clock speed of the processor . When the speed of the processor to work on non- standard , then the third part of the work will remain the same as the standard speed .

PREPARATION AND PHASE overclock .

Because the overclock is a trial and error activity or trial and error . The earliest stage is that you have to know where the place to reset the BIOS when the computer is locked when it is done overclocking . If the BIOS can not boot normally , the mainboard can work pengembalin in order to reset the BIOS back to the default position to restore the BIOS .

Another thing is patience . Try doing processor speed increase step by step . Excessive upgrading will only mess up your analysis . Slowly overclock will be easier managed , and analyzed the moment whether the computer has been unable to work properly . And try to enjoy some of the applications that everything is running normally before increasing the processor speed higher.

In the event of failure eg computer experience hangs , blue screen or fail to run certain applications . Go back to analyzing the hardware part . And look for the section Which makes the computer failed overclock .

SOME PARTS ARE OFTEN LEAD TO FAILURE DUE TO OVERCLOCK .

1 . Memory is generally the most dominant . When overclocked occurs , the memory section must balance processor speed .

2 . Overheating occurs when the processor heatsink using standard

3 . Power shortage in the processor because the mainboard or power supply is inadequate

4 . The ability of the mainboard does not support , or are not designed for overclocking

5 . The ability of other hardware devices are not able to work at overclocked speeds

THE MOST IMPORTANT PART OF OVERCLOCK IS MEMORY AND POWER SUPPLY .

A few years ago you would never know the memory type with speed PC100 SDRAM , PC133 and PC150 . Currently, the development speed of PC2100 DDR memory is shared with , PC2600 and PC3200 . And the type DDR2 PC4300 also subdivided into , PC5400 and next. And the last memory dual channel technology that provide greater bandwidth with 2 memory modules have to be installed together .

Let's take the example of the Pentium III 500Mhz bus speed of 100MHz . To become a 667MHz overclock the computer should be setup with a 133MHz bus . And the memory of PC66/PC100 should be replaced with a standard PC133 and PC150

If you are using a Pentium 4 1.6Ghz with 100Mhz DDR memory and the computer bus using PC2100 enough . But with speed 133MHz overclock from 100MHz into the computer memory speed ideally using PC2700/DDR333 .

Choice of memory speed is not a problem when overclock the processor . Just to optimize computer performance , required a memory abilities as well. If the purpose overclock to maximize the overall performance of a computer is memory speed becomes essential.

For example , using speed 200MHz processor with dual -channel memory for optimal performance on a memory with DDR PC3200 DDR memory speed . Is PC2700 or PC2100 memory speed can not be used . The answer : they can be used . Some motherboards now include multiplier option or for sharing memory with processor speed . By lowering the speed of the computer memory multiplier to use lower memory speed

The impact of lowering the memory multiplier is certainly contrary to the purpose of overclocking . On one side of the processor speed increases , on the other hand is memory speed is lowered . What happens if the memory speed downgraded . Of course part of the memory only produces a lower bandwidth or have a lower transfer speed is reduced due to the low clock . On the side of the processor or CPU is working fast , memory side instead be a delay in the transfer of data between the processor to the memory . The result would make the computer slightly lower performance

The use of the memory multiplier is only useful if the memory can not work when the processor is done too high overclock . For example, you use the type of DDR PC3200 standard types available in the market . With increased processor performance by overclocking , generally there is a failure in the memory . Because the memory is not able to work outside the standard speed limit . The choice is to lower the speed multiplier one step from the existing rate .

For example in the picture below . With a processor speed of 200MHz berFSB the standard memory speed will be driven at 200MHz x 2 = DDR400 PC3200 or equal to the speed . Processor overclock 10 % of the required standard speed processor memory speed at DDR440 speeds . If memory is not able to work at DDR440 speeds , choice by lowering the speed multiplier 1 step below . So the memory will work at the speed of 365Mhz or almost the same as PC2700 speeds . Because it has a speed of DDR400 memory , the speed of 365Mhz is still acceptable under the standard speed or memory .

DESIRE IN WHICH GENERALLY WANT TO REACH BY THE GAMER .

One's desire to have a faster computer can not be separated from the existing hardware support . Currently, there are many types of premium memory market. Premium choice of using memory types is not easy . Besides being more expensive , higher memory performance than standard memory has a distinctive tersendir .

We had to ask at a moment 's largest memory manufacturers . Why memory is made of premium ( for overclocking ) and standards . Simple answer from them .

MEMORY CHIP IN FOR SOME WITH MODEL :

The first is a standard memory sold in the market . Memory standard is aimed at end users . Generally the standard memory chips are cheaper and assembled back into a memory module. Or already assembled into memory modules and sold to companies for use on computer branded computers . Type of memory standard mass-produced in large quantities so that production costs are cheaper .

The second type is a special memory for sale . Usually memory is sold exclusively intended for companies renowned memory . Companies with a certain brand of memory module manufactures memory and labeled brand of memory module manufacturer . Generally memory with a particular brand already has insurance against various hardware compatible . So the emphasis is compatible with the hardware available in the market

The third is the order for the type of memory based on the Premium . The maker of memory just makes memory types of companies dipesanan Premium OEM / brand specific companies large amounts of memory . Because it is made to order , despite having an huge amount but still expensive because it has quality . Premium Memory is made ​​with high ore costs . In addition to having a higher durability , premium memory capabilities will never be obtained on standard memory and almost never sold directly by the manufacturer 's own memory . Criteria of Premium memory is separated from the memory requirements of the standard . Usually marketed with low latency levels , or have the ability to work at high clock . Specifically for gamers , prefer premium memory . Premium memory type generally has a higher resistance .

Dual benefit also come with premium memory . Currently there are 2 choices between premium memory with low latency air- resistance standard and premium memory clock that is able to survive at high clock speeds but high berlatency .

To use memory with high clock capability , more ideal to use to overclock . But it has a weakness with high latency eg berlatency named with PC4400 2.5-3-3-6 , so the computer looks less responsive . But the memory that is better able to withstand the high clock and were able to receive the voltage above the standard ( we call vDIMM ) . This option must be taken , because this is just a special type of memory that is able to balance the needs of data transfer between the processor memory .

Conversely, a premium air- memory latency . This type of memory has a dual function . When you want a computer with not too high overclok recommended fixed using air- latency memory for example 2-2-2-6 . Computer looks more responsive , because working memory is so fast compared to the high clock memory and has a high latency . Besides good response effect on air- latency memory , overclocking is still possible as long as the use does not exceed the limit of maximum memory capability . By playing a higher latency in low-latency memory air , still allowing the memory to work at a greater clock . For example PC3200 with 2-2-2-5 latencies at 200MHz speed , still able to work at 250MHz with 3-3-3-6 latency . The choice lies in sipemakai , does require endurance memory clocked at a high level or wants to retain the ability to be more responsive to working memory .

OVERCLOCK COMFORT WITH POWER SUPPLY QUALITY ( GRADE PREMIUM )

Last is the ability of the power supply . Premium power supply has a high level of efficiency as well as good protection as well as function as a power supply for the computer security .

Power supply premium has several features such as overvoltage , overload , short protection and so on . System protection on the output voltage is critical . When the power supply is experiencing an overload , the output voltage will generally increase . At the position of harm , then the power supply will shut itself down in order to maintain the existing devices do not experience overvoltage .

Protection system is needed for the overclock that computer in safe assets . If you ever find a motherboard and processor power supply keeps burning because only provide power supply to the computer . It is one of the weaknesses of the system impact of power used .

It may rarely occur in the use of premium-class power supply . Surely it would be ridiculous if someone uses a standard power supply for 300 thousand , but mounted on a set of hardware that cost over 10 million dollars .

But the most important part is the level of power efficiency . On the power supply is known as power efficiency / power efficiency ( power factor ) as input and output ratio . Input power is required by the power supply from the power source , while the output is issued by the DC power from the power supply load a computer .

Is it the sense of power efficiently . efficient power consumption is the ratio between the input with the output generated . When a power supply has a power ratio of 50 % , meaning that 50 % of power output produced from 100 % input . For example , a power supply with 300W of power with a maximum ratio of 50 %, then the resulting output is 150W .

Currently, there are many manufacturers of premium power supply . Power supply of premium generally has a power level of up to 65-85 % efficient . This means that the power output is more efficient than a standard power supply . With 400W labels and 75 % power efficient , which means the output power can be given to a hardware device reaches the maximum level of 300W DC to AC 400W power requirements . By doing both VGA and Processor overclocking , power requirements will increase . A good idea to look back at how the ability of the power supply to the load of hardware . Provides a standard power supply and power efficient low -level waste will only electrical power and confound your analysis when overclocking

With the above article , the reader is expected to already know more about the use of hardware , especially for overclocking . It is expected that you also do not assume that the overclock is a crazy -risk activities . Anyone can make a computer faster than standard . Overclock not to damage the hardware activities , but only improves the performance of the computer in order to work better .

Overclock not only aims to buy cheap processor to produce the same speed with a faster processor and expensive . But the whole harware maximize existing device , to work as closely as possible . Impact, a computer of your dreams is more convenient , faster , and more responsive in order to be enjoyed .
