Currently, when we talk about processors, we are talking about two different types of frequencies. Base Frequencies and Boost, really, ARE NOT REAL. All the processors of the market, whether Intel or AMD, operates at 100 MHzbut then, How do they achieve these very high frequencies?
The first thing we need to understand, in a simple way, is the meaning of frequency in a processor. When we talk about frequency, we mean the number of operations it can perform in one clock cycle. You should know that when we talk about clock cycle, we are talking about 1 second.
Let’s try to make it clearer. If a processor is running at 4.0 GHz, that means it is running at 4,000,000,000 Hz. This means, in a very simplified way, that the processor can perform 4 million operations in one second, something brutal.
The “trick” of the frequency of our processor
To understand this parameter, we mustLet’s go back to the first CPUs. These were initially not as fast, with operating frequencies weak equal to the system bus. Thanks to the development, this parameter increased and far exceeded the frequency of the system bus.
Believe it or not, the the system bus frequency remains at 100 MHz and nothing can go faster. If this were to happen, endless problems could arise.
Of course, right now you are confused because when we talk about a commercial processor, we are talking about working at “x” GHz or “y” MHz graphics cards. Well, to “fix” the lag the multiplier parameter has been introduced.
What is done is that the frequency of the components is increased by an established relationship. THE frequency multiplication factor to not depend on the data bus.
This factor is nothing more than the decomposition of the total working frequency into small cycles
Now you might be wondering why the system bus frequency is not increasing? Also, exceed 100 MHz This is a big problem that generates a lot of instability and problems. It can be changed, but usually it doesn’t work.
What about overclocking?
When we talk about overclocking or increased processor and/or graphics card frequency, which is to manipulate is to multiply it. Modifying it is extremely simple and does not cause any problems. If you don’t go all the way when modifying it, a blue screen appears and the values are restored by the motherboard without doing anything.
But play with system bus frequency it’s a lot more complex. It should be borne in mind that changing this parameter to only 1 MHz, bringing it to 101 MHz it affects to all components. We modify the working frequency, also from the SSD, he chipset or the USB sockets.
This may result in system malfunction or inability to turn on. Usually changing this setting means not even being able to get into the motherboard. Fist-sized beads of sweat are probably running down your face at this point. At this point you need to reset the BIOS of the motherboard, which is not complicated, but not suitable for everyone.
Note that many processors without overclocking compatibility means that we cannot change the multiplier. Yes, we can change the system bus frequency, although it is not recommended.
So much so that Intel in the 13th Gen Core blocked this setting to avoid issues. Thus, only Core-K and Core-KF currently allow overclocking. This prevents system damage and other issues from affecting settings that should not be changed.
