The performance of various electronic components is determined, among other things, by the frequency at which they operate, the same frequency that is set for them in the factory and usually represents the most stable working frequency. However, this does not mean that the chip is unable to operate, theoretically, at any other frequency and this is where the user comes into the picture. There are 2 main reasons why a user decides to speed up his computer. One, to gain performance improvement from your computer for free, and the other, an attempt to push system performance to the maximum possible, Maayan ספורט An armchair, if you will.
Before we begin with this article, we will outline a number of basic concepts that will be repeated in the article:
Bass: The frequency at which all system components communicate. The bass is determined by a crystal in which an electric current passes.
Product: In order to achieve high end frequencies, it is necessary to multiply the basic frequency of the processor. In the past, the entire system worked at the bass frequency, but now the processor is able to operate at higher frequencies using the product.
cached memory: זיכרון It is divided into several levels: first, second and in some cases third. The first is the speed at which its processor works, and this memory is actually the memory that goes through the haste. The instructions that the processor receives from the operating system, for example, are also stored in this memory. זיכרון A second-level cache is the memory that the processor uses for the information it needs most urgently, because if it is not there, the processor will have to turn to much slower system memory (RAM).
The fast, as we perceive it at least, is divided into two types. One is the change in the frequency at which a certain component acts in order to improve its performance. And second, a physical and sometimes physical change that allows access to features that would not have been available in the component had it not been for the change.
Some of you who have experienced haste on their own, or have read about it in our forums, have probably realized that there are differences in the quality of the haste between elements of the same series. At first glance, the number Processors Of the same series are completely identical to each other. However, with a closer look it seems that the differences between them are numerous. As an integral part of the nature of the production process, some processors descend from the production line when the core is free from manufacturing defects, and on the other side of the barricade, Processors In a situation that is not worthy of use at all. Moreover, every manufacturer Processors Examines its employees under various conditions such as exposure to a wide temperature range, under heavy processing load and at various voltages. This torture mask enables the manufacturer to market the best processors, which have passed the tests very successfully, to the high market as extreme processors and the other processors to the average market.
Our story begins in the 80, when Intel The young woman supplied the processors to the IBM computer giant, which first gained its status as a manufacturer Processors Excellent. During this period, The fast An initial frequency of 4.77 MHz was made possible by removing it by brazing the crystal that determined the base frequency and replacing it with another crystal.
Around the same time, another giant was born; The processor manufacturer AMD Has obtained the license to set x86 's commands Intel, And began to produce Processors Herself.
The veteran users among us probably know that somewhere in the 80s and 90s we all had hands-on experience in a hurry - the turbo button. In fact, this button changed the speed of the system to allow old games to work smoothly. This is because games in the past have relied on processor frequency instead of relying on their own work rate. by the time Processors New and faster games were launched, some of the games failed to synchronize themselves and suffered from instability and crashes. The original turbo button actually slowed system performance. Later versions of the turbo button, which include different settings, speed up the system.
The user's freedom to set processor speed continued during the merry 486 days, with the processor still operating at the same basic speed as the rest of the system, which included the cache memory (which had a dedicated expansion slot on the motherboard and sold with the processor), PCI slots and memory . However, as processor speed grew at a dizzying pace, the speed of other components failed to maintain the same pace of progress and the stability of the system was undermined. The proposed solution of Intel Previously valid to this day - multipliers and divisors. For example, if the base frequency at which the system worked was 66 MHz, now thanks to the product, the processor will start working at double the frequency, and communicate with the rest of the system every two clock cycles.
