Most computer CPUs and GPUs come from the factory with a maximum speed setting certified by the manufacturer. Running your computer within those speed limits and with proper cooling ensures that your computer performs without problems.
However, the nominal clock rate given by the manufacturer is more often than not never nearly the upper limit of the actual CPU and GPU performance limit.
There is still some performance reserve that you can tap into if you need more speed. This is where overclocking comes in.
Overclocking is the process of setting a higher multiplier or clock rate, typically within the computer’s BIOS.
In doing this, it forces the CPU and or GPU to handle more operations per second, thereby increasing the speed of the processors and the overall speed of the system.
While overclocking opens up more performance from your CPU and or GPU, the excess heat built poses a reliability and longevity risk to the processors.
One must take proper steps to monitor and manage the additional heat load to mitigate the reliability issues occasioned by excess heat production and build-up.
Additionally, the power source must be tweaked to provide ample power to meet the higher electrical current demand. Failure to consider these aspects might result in the total failure of the processor or CPU in general.
Moreover, because the performance of the whole system depends also on the speed of the RAM, you must take into consideration the memory speed aspect as well.
If RAM is not fast enough to store and process the faster data throughput coming from the processors then your whole system will suffer. That is where RAM overclocking is also another important aspect to consider for better overall system performance.
So, why would you want to overclock your CPU or GPU and risk its failure? The obvious reason for overclocking is to get more performance from your computer in general.
Overclocking comes in handy when running particularly demanding programs. On the other hand, overclocking your GPU comes in handy when gaming. An overclocked GPU can help yield smoother action and produce better graphics much more reliably.
Herein we will explore 20 of the best overclocking software for CPUs, GPUs and RAM to help you reliably and safely overclock your hardware. The list below is in no particular order.

Is Overclocking the CPU Safe?
These days, CPU overclocking could be considered quite safe if you know what you are doing. The most popular overclocking software protects users from damaging their systems with bad settings.
Also, modern CPU components are manufactured with protections in place so that the device won’t get destroyed easily.
However, keep in mind that unrestricted overclocking can lead to bricking a CPU in rare cases. Moreover, a handful of issues arise from overclocking a CPU with any clock speed if you are not careful.
First and foremost, overclocking leads to higher operating temperatures. Major frequency boosts can lead to extra wear and tear due to the constant heat generated here.
An overclocked CPU utilizes more electricity to run, which can cause wear on a computer’s PSU (Power Supply Unit). Sometimes, an overclock may cause system instability or frequent crashes as well.
Is Overclocking RAM Safe?
Unlike CPUs, a computer’s RAM doesn’t generate much heat. Users face far fewer issues when overclocking RAM.
If the RAM is overclocked incorrectly, the system will crash and reboot but in most cases there will not be a permanent damage.
For that reason, most people shouldn’t hesitate to overclock the RAM in their system. They stand to reap various performance benefits in doing so.
It’s difficult to cause permanent damage to the system’s RAM through overclocking. Regardless, users should focus on system stability while overclocking RAM.
Nobody wants to see their system crash on a regular basis after all. RAM overclocking is quite safe because the consequences are almost always temporary.
Pros of Overclocking CPU and RAM
By overclocking a CPU or RAM, users increase the operating frequency and speed of the hardware.
Higher frequencies equate to better performance. Hardware like the CPU or RAM can complete tasks faster than their stock versions. In real world usage, this leads to faster load and render times.
A program might launch a few seconds faster. Rendering a video file might occur noticeably faster and also gaming will be smoother and faster as well.
Without a doubt, overclocking comes with tangible benefits for the user. Gamers can squeeze extra frames out of the existing hardware. Nobody’s going to complain about a faster computer, especially as hardware starts to age.
Overclocking provides an excellent alternative to replacing older hardware. At the expense of more power consumption, an older CPU or slower RAM can be overclocked to make tasks manageable.
An otherwise outdated PC could run like an upgraded machine without the cost of replacing hardware. Not all CPUs can be overclocked though, but most RAM can be overclocked.
Cons of Overclocking CPU and RAM
CPU and RAM overclocking does come with certain downsides that require consideration.
First and foremost, overclocking adds wear and tear to the hardware over time. Higher operating frequencies and clock speed equate to higher power usage and heat generation.
An overclocked CPU or overclocked RAM may come with a shortened lifespan. Safe overclocking minimizes this wear and tear, but it does occur nonetheless.
As previously mentioned, RAM is almost completely safe to overclock. On the other hand, users can cause irreparable damage to a CPU if they use overclocking software they don’t understand.
Luckily, most software comes with safety features built in to shut down the system as soon as issues arise. An individual should gain a basic understanding of overclocking before beginning this process because it’s not always foolproof.
Finally, higher power consumption leads to increase electricity costs. The consumption can wear out a system’s Power Supply Unit (PSU) a bit sooner than expected.
Added electricity consumption won’t make or break the bank for most people, though. In the end, safe and effective overclocking is more than possible with both CPUs and RAM modules. Users can reap these benefits on both old and brand new hardware alike.
