Are you working on your thesis and the PC is so slow that you want to write it by hand? Or, more generally, for some time the computer has been responding less quickly than usual and you suspect that the CPU is responsible for everything? If so, let me help you deal with the problem as much as possible.
If you want some "tip" on how to speed up the CPU
before thinking about a replacement or a hardware upgrade of your computer
(which will have to happen sooner or later anyway!), Let me explain what you
can do to try to "revive" the entire operating system.
Do not worry: even if manual skills are not your strong
point, you can give a boost of energy to your computer's CPU through software,
by acting on the operating system settings and using programs designed for the
purpose. Of course, miracles cannot be done, especially if your computer's CPU
is now obsolete, but at least a minimum the situation should improve. Happy
reading and good luck for everything!

How to speed up your PC CPU
The CPU (Central Processing Unit) is often referred to as
"the brain of the computer" and, although inflated, it is a perfect
figure: it is, in fact, the component that gives the instructions to the rest
of the hardware, for example the RAM , to work; and its slowdowns cause a
general slowness of the machine.
Mind you: CPU slowdowns aren't always anomalous. If, for
example, you are usings a video game or video editing program , slowing down
your computer is completely normal. On the other hand, when, at least as far as
you know, you are not making use of software that is expensive in terms of
hardware resources, and the computer is not lean and snappy, there is some
problem to be solved. This is where this tutorial come into play.
There are several techniques to speed up the CPU : some
consist of measures implemented by the operating system, such as the
identification and consequent closure of processes that are making excessive use
of the processor; others involve the use of special software, designed
specifically to optimize the use of the processor.
Overclocking deserves a separate chapter : a practice, not
really within everyone's reach, which allows you to push the CPU beyond the
limits set by the manufacturer by acting on the computer's BIOS. I'll tell you
more about it later. But now let's go in order and start with the “lighter”
solutions.
How to speed up the CPU without overclocking
Here are some methods to speed up the CPU without
overclocking , which are simple to implement and do not present any risks to
system stability.
Limit the processes that consume more CPU
As easily understood, the first thing to do is to identify
the processes that consume more CPU and eventually close them.
To start, right-click on the Windows taskbar (the one with
the Start button) and select the Task Manager item from the context menu. In
the window that opens, if necessary, click on the option to show more details
and go to the Processes tab .
What you see is the list of operating system processes and
applications that are currently active. The left column shows the name of the
activity in progress while on the right, in order, there is the column called
Status in which there are any information , then find the percentage of CPU
used by each single process; followed by the amount of RAM expressed in
megabytes, then the writing and reading activities that each single process
performs on the disk and, in the last column on the right, the amount of
network traffic required by each single activity carried out by the operating
system.
If there were anomalous processes, the percentage of the CPU
used would jump to very high values, often even at 100% . If you notice
processes with these characteristics, Google their identity and, if they are
not essential system processes for the functioning of Windows, close them. If
it is a program, you can close it directly from its window; if it does not
respond or does not have a window to call up, you can act from the Task Manager
by right-clicking on the name of the process and choosing the item End task
from the menu that opens.
When a process is giving the computer a hard time, an
eloquent message appears in the Status column (the one immediately to the right
of the name of active processes) such as, for example, “the application is not
responding”. In short, impossible to go wrong.
Disable unnecessary programs at startup
When you turn on your PC, programs run and, in all
likelihood, you use some of them sporadically. In addition to loading the CPU,
they also have an impact on the RAM and, therefore, cause a general slowdown of
the system.
To avoid unnecessarily burdening the performance of your
computer, I'll explain how to disable unnecessary applications in automatic
startup . Open Task Manager by right clicking on the Windows taskbar and
selecting the appropriate item from the context menu.
Now go to the Startup tab and locate the unnecessary
processes. There is no definitive rule for managing software startups, as your
computer runs a variable number of programs when you turn it on, depending on
the ones it has installed on your hard drive. The selection principle is
therefore elastic but, in principle, leaves everything that has to do with
security in the Enabled state , therefore, for example, Windows Security
notification icon (which is linked to the checks carried out by Windows
Defender ). If you have other security suites installed, then it is worth
leaving the related service enabled on startup. Likewise, if you use cloud
services like Google Drive orOneDrive , you should let them run when your
computer starts.
In principle, all the programs that you do not use daily can
be placed in the Disabled state (if they are not already) by right -clicking on
the activity that you do not want to be performed when the PC starts up and
choosing the Disable item from the context menu . If in doubt, you can choose
Search online for additional information on the related activity.
Disable background applications
Windows 10 and later make discreet use of native
applications, such as the calculator or the Maps application . The default
settings provide that all of them can be updated even when they are not
actively used and that part of these can send notifications. All work that
burdens, once again, on CPU and RAM (little, but still burdens us).
To disable its operation in the background, simply click on
the Start button (the Windows flag) and select the Settings item (the one
represented by a gear ) from the menu that opens. In the next window, go to
Privacy , then to Background apps (from the left menu) and disable the apps you
deem unnecessary.
Also in this case there is no precise rule. My advice is to
leave the Microsoft Store and Windows Security background activities running .
Applications Cortana , Camera and My phone can be left active if you treat it.
The same goes for other applications that you use quite frequently. The rest
can be deactivated by clicking on the switch to the right of each single
application listed.
Programs to speed up the CPU
After having done some manual interventions to relieve the
CPU of some tasks that are delegated to it by the operating system, I want to
talk to you about some programs to speed up the CPU , which can do for you: one
of these is CPUBalance .
If you have never heard of it, it is a program that takes
care of restoring the workloads assigned to the CPU, according to automatic
rules but that you can also change at will (if you know where to put your
hands). The algorithm on which this software is based prioritizes the
applications you are using, making sure that all other processes running at the
moment stress the CPU as little as possible.
CPUBalance is free, but it is available in a Pro version
that includes automatic updates and allows you to support the work of
developers: it costs 8.43 euros per year .
You can download CPUBalance from the manufacturer's website
by scrolling the page until you identify the blue Download CPUBalance button ,
click on it and wait for the download to finish. When the download complete,
open the .exe file obtained and click on Yes , OK , then on Accept , Next and
Install , to complete the setup.
Now, start the program, click on the Yes button and adjust
everything as you like. The default settings , in my opinion, are acceptable:
when a process you are not using takes up more than 20% of the CPU, the
software adjusts its requests below that threshold but never below 4% because
otherwise the process would risk or to freeze or terminate abnormally.
The fact that this program comes into action when the total
processor load is greater than 11% makes it practically always active because
it is enough to have opened a small number of applications to reach this
percentage of workload.
The only option I recommend you change is the one related to
disabling the software when you are not using the PC. To do this, click on the
ProBalance Options menu , then on Advanced Options and, at the bottom of the
window that opens, check the Disable ProBalance when the PC is inactive box ,
selecting a minute from the drop-down menu that you find immediately below (I
recommend you set it to 5 minutes) and then clicking on the OK and Save changes
buttons .
This will also allow you to save battery if you use a
laptop. Seen? Nothing particularly complicated.
How to speed up the CPU with overclocking
Are you looking for a method to "squeeze" your
computer's CPU ? Then you should consider overclocking .
To understand what it ti, you need to know that the
processor works at a speed, called clock frequency , which today is expressed
in GHz and which measures the amount of cycles performed every second. To give
you a practical example, if your computer's processor has a clock rate of 3
GHz, it means that it runs 3 billion cycles per second .
The manufacturer sets a speed that it believes can be
reached by the hardware it produces without damaging it, therefore a frequency
below the real possibilities that guarantees its safety.
Overclocking means exceeding the clock frequency and making
the hardware more performing. Are you wondering if it is safes to overclock a
processor? A precise question to which I can honestly answer yes, but within
certain parameters. There are many myths about overclocking, suspended halfway
between popular legend and the heroic deeds of "geeks" that tend to
magnify the experiences made.
Over the years, CPUs have become more and more performing
and it is true that overclocking reduces their life cycle . Equally true,
considering the pace at which hardware evolves, it is very likely that you will
change computers before it comes to its natural end. What remains unchanged is
that putting stress on the CPU to make it perform at its maximum increases its
heating, and raising the temperature in the PC case too much can damage various
components .
Nowadays it is almost impossible to "break" an
overclocked processor, because if something does not work properly, the
computer will continue to restart or display the infamous Blue Screen Of Death
, the blue screen through which the operating system communicates that
something it's not going the right way.
There are several ways to overclock the processor: there are
specific software that takes care of it or, if you feel like it, you can
intervene directly on the BIOS / UEFI of the PC (which, in case of problems,
you can easily reset ).
If you want to know everything about overclocking, I invite
you to read this tutorial that will satisfy all your curiosities about it and
will give you the right "tips" to get started.
Other useful solutions
After having done a bit of tuning to the computer's CPU, the
result does not satisfy you? Does your computer still seem slow to you? Then I
have another series of solutions to offer you.
The CPU may not be the only cause of computer slowness. The
RAM , the hard disk and file fragmentation, the graphics card settings, the
presence of malware or viruses , the driver or not updated the operating system
and more may be responsible.
It is not a conspiracy against you, the computer does not
want you badly. Even the most experienced users tend to underestimate the
importance of routine maintenance .
If you want to know more, this tutorial is for you, showing
you simple operations that will solve any situation, even those that seem
desperate.
How to speed up the Mac CPU
Wondering if something can be done for your Mac's CPU as
well? The answer, between good rules of use and a little maintenance, is
affirmative.
The first thing I recommend you do is check which software
is possibly putting a strain on the CPU. You can do this by clicking on the
icon with the colored squares on the Dock bar . Then click on the Other folder
and then open Activity Monitor , an application that shows the list of
processes running on the Mac.
To view the list of processes that consume the most CPU,
select the CPU tab at the top, then press the % CPU tab , to make sure you sort
the processes according to the processor load used in real time.
Now, check the processes for a few minutes and, if you
notice any "suspicious" ones that consume a lot of CPU (eg over 90%)
for a long time, google what it refers to and, if it is not an important
process system or an application you are using and need, terminate it.
To do this in a "clean" way, open the program
referenced by the process to be terminated, click on its name in the menu bar
(top left) and select the option Exit [application name] . Read more here . If
the program does not respond or does not have a visible window, you must close
it via Activity Monitor : click on its name , then on the [X] icon at the top
left and, finally, on the Exit button . Read more here .
You can also save RAM by limiting the number of applications
that are launched when you turn on your Mac. A quick operation that you can
perform by clicking on the System Preferences icon (the one that looks like a
gear that you find on the Dock bar ) and then clicking on the Users and groups
icon . From here, you need to select your user profile in the left part of the
window and, this time in the right part of the window, click on the Login Items
tab .
What you get back is the list of software that starts with
the operating system. Select the one you want not to run automatically (making
sure it is not important to you or to the functioning of the system) and click
on the [-] button located at the bottom left. If you wants to deepen the topic
you can do it here .
What about overclocking ? Given the "closure" of
both software and hardware of Apple computers, it is not a matter that is worth
dealing with: basically, if one chooses to use a Mac it is because he wants an
already super optimized computer that does not require operations such as
overclocking to give the best of oneself.
How to speed up the Android CPU
And with Android , how do we put it? Is it possible to
overclock the CPU of a smartphone or tablet equipped with the “green robot”
operating system? The answer is yes: you can change the processor frequency,
but it is quite risky and not recommended.
In fact, it provides for the unlocking of the operating
system (and often the deletion of data) via the root . After that, by
installing a special application it is possible to balance the minimum and
maximum CPU frequency by altering the default values.
As you well understand, among possible overheating due to
configuration errors, the potential disadvantages of this practice outweigh the
advantages. You can, however, speed up Android in other ways that I tell you
about in the tutorial I just linked to.
