What Is Overclocking: How It Works, Execs & Cons, and is Overclocking Value It?

Final Up to date: April 22, 2020

To some the time period overclocking might conjure some type of overly-dramatic visualization of a crazed, long-haired, large-spectacle-wearing hippy-genius in a high-tech lab someplace pouring liquid nitrogen on {hardware} like some type of PC grasp race god. Nevertheless, the fact is overclocking is much more widespread, accessible and straightforward to do today and also you don’t have to be a genius within the slightest because of nice software program and instruments being out there.

Plus, the dangers related to overclocking are lower than up to now with PC {hardware} today being rather more versatile and being able to resist much more. Nevertheless, regardless of overclocking being removed from rocket science and changing into loads nearer to idiot-proof within the trendy age, there are nonetheless dangers related and little nuances you want to pay attention to, and so you need to determine for your self whether or not the additional potential efficiency is price it on your specific state of affairs.

Overclocking isn’t for everybody and might not be well worth the effort and time on your specific state of affairs. Plus, it requires a little bit of persistence to do proper since you do not need to simply dive head-first and tinker with {hardware} settings as a noob with out realizing what you are doing. 

When you’re constructing your first gaming PC you must most likely give overclocking a miss except you’ve got good causes to do it.

Lately are lengthy gone; in trendy instances, overclocking is comparatively simple



It isn’t at all times essentially the most sensible factor to do, however do not get me improper as there undoubtedly are locations for overclocking to get you extra on your cash and/or prolong the lifetime of an growing old system. This information will cowl what overclocking is, the professionals and cons to overclocking, how to decide on elements for overclocking, and for individuals who need to go even deeper down the rabbit function now we have additional modules under on precisely overclock each your CPU and GPU utilizing the most recent strategies and software program instruments. Strap your self in and will the power be with you and your elements.

What’s Overclocking? The way it Works

Laptop overclocking is forcing a element such because the CPU to run at increased, quicker speeds than the default (often known as “inventory”) pace set by the producer, and is completed by altering settings in a software program program or in your motherboard BIOS. The rise in efficiency you’ll be able to create by way of overclocking will rely upon varied components reminiscent of the precise {hardware} element mannequin and what base efficiency it has, how efficient your {hardware} cooling setup is, how a lot you push your half/s, and the way a lot threat you’re comfy with amongst different components.

The free enhance in efficiency that comes from an overclock isn’t free in concept, and comes with added dangers to your system reminiscent of overheating, system crashes, voiding your warranties, {hardware} injury, decreasing {hardware} lifespan, and even full {hardware} failure. Total, overclocking isn’t usually really useful for novices constructing their first PC because of the additional complexities and potential issues it may possibly create.

It’s solely actually prompt for the curious with the time and persistence to do it the correct approach, or these trying to absolutely maximize efficiency for his or her cash who’re keen to simply accept the potential dangers. Nevertheless, as talked about earlier than the reality is that today it’s loads much less dangerous and less complicated than it was as soon as was, and there are methods to do it fairly safely that drastically restrict the entire potential downsides.

For instance, if you happen to push a component past what it’s safely able to, your system might merely crash or refuse as well indicating that you have to tone the settings down a bit; and you’ll then reset the settings and be up and working once more as regular with out issues. Tlisted below are additionally fail-safes constructed into trendy CPUs, GPUs and motherboards that assist forestall {hardware} injury and failures when overclocking.

Overclocking isn’t some forbidden darkish artwork that ought to solely be left to the consultants and excessive fans; it’s fairly a standard apply today amongst intermediate PC builders, and even with some whole novices who’re eager on actually stretching their system additional or who’re simply inquisitive about these kinds of issues.

Elements that may be overclocked embrace the CPU, GPU (graphics card), reminiscence (RAM) and monitor (to extend the refresh charge). Total, the CPU is the most well-liked half to overlock adopted by the GPU. When it comes to simplicity, the GPU is the best general, and can be the most secure typically. However don’t get me improper; overclocking a CPU could be very, very secure as nicely assuming you’ve received the correct issues in place (defined quickly).

Technically, the method of truly overclocking a component goes like this: you employ sure software program (or your BIOS) to manually change settings of a specific element reminiscent of its pace. With a processor, you’d enhance the clock pace which is measured in cycles per second or Gigahertz (GHz). This may be carried out a wide range of methods reminiscent of rising the clock pace immediately, altering the multiplier, or altering the bottom clock (BCLK). This can all be defined within the module on overclock CPUs.

With a graphics card, you’d enhance the clock pace as nicely, which will increase the pace at which graphics are rendered and due to this fact can enhance your gaming efficiency. With GPU overclocking it’s also possible to tweak different settings just like the reminiscence clock pace which boosts the pace at which texturing is processed. With each the CPU and the GPU you even have the choice of accelerating the voltage, which is the quantity of energy given to that element. This will additional enhance the efficiency your element is able to however comes with added threat of damaging parts.

Potential Execs to Overclocking

The principle good thing about overclocking your PC is getting quicker general efficiency, particularly in CPU or GPU demanding purposes reminiscent of video games, video modifying, 3D rendering, and so on.

  • Overclocking might prolong the life of an older PC. As a substitute of upgrading elements or constructing a brand new system altogether, an overclock might hold your rig within the recreation for barely longer than it could in any other case.
  • Overclocking might prevent cash since you might efficiently use it as a approach to purchase cheaper parts after which overclock them to the identical efficiency stage of dearer elements.
  • In sure instances overclocking might optimize general system efficiency as some setups may have bottlenecks the place overclocking of 1 half might assist the efficiency of one other half.
  • Overclocking could also be enjoyable and attention-grabbing to you if you happen to love computer systems, take pleasure in studying, and have enjoyable attempting new issues.

Potential Cons to Overclocking

  • Elevated warmth generated from the element/s you’re overclocking, which will increase demand for cooling of each the precise element/s and the within of your case.
  • Elevated energy consumption that means you might want a greater and/or extra dependable energy provide.
  • With the elevated want for max cooling, your system might produce extra noise as a result of followers working time beyond regulation.
  • Overclocking might make your system unreliable and will increase the possibilities of system errors reminiscent of blue screens and different points.
  • As a result of additional calls for being put in your elements, overclocking might cut back the lifespan of your {hardware}.
  • Overclocking might void the guarantee of your parts so if something goes improper it’s all on you and your pockets.
  • Might injury or completely destroy your {hardware} if you happen to push a element too onerous or do one thing improper.

Which Elements Can You Overclock?

CPU Overclocking

The processor/CPU is the most typical element you could push additional than its initially supposed manufacturing facility pace, with the most effective case efficiency enchancment usually being as much as round 15-20%. Overclocking your CPU is definitely fairly secure and pretty idiot-proof as long as you don’t apply additional voltage (defined later) and you’ve got the cooling setup to deal with the additional warmth. When you push a CPU too onerous by elevating the clock pace too excessive, your system will sometimes refuse as well and you’ll then change it again till it really works.

To overclock your CPU you’ll want a appropriate CPU that has what’s referred to as an unlocked multiplier (most if not all AMD processors, and Intel processors which have a “Okay” of their mannequin quantity), an overclocking-friendly motherboard, an aftermarket CPU cooler, overclocking software program, and ideally a dependable PSU. To be taught extra about overclocking your processor see our CPU overclocking beginner’s guide.

GPU Overclocking

It’s also possible to overclock a graphics card to squeeze out extra gaming efficiency, with best-case efficiency will increase going as much as 15-20% similar to with processors. Once more, if you happen to don’t apply extra voltage it’s fairly secure as nicely. 

To overclock a graphics card you’ll want software program of which there are many free choices (defined later). In contrast to a processor although, you’ll be able to principally overclock any graphics card available on the market. Some graphics playing cards, that embrace “OC” within the mannequin quantity, are already overclocked by the producer. Study extra with our full GPU overclocking guide.

RAM Overclocking

You possibly can overclock your reminiscence to run at increased speeds in case your motherboard helps these increased speeds which might equate to barely quicker efficiency in video games which can be extra CPU-intensive (because the RAM helps the CPU) and non-gaming purposes that closely depend on reminiscence pace. 

RAM overclocking is so simple as enabling a setting or two within the BIOS, and typically it is necessary to get the precise listed pace of the RAM that you simply purchase as oftentimes the motherboard will default your RAM to a decrease pace. For instance, if you happen to purchased 3200MHz modules, it is not unusual on your motherboard to default it to say 2133Mhz, wherein case you technically must overclock it within the BIOS to set the pace to 3200Mhz.

Overclocking Your Monitor

Yep, you heard that proper. Monitor overclocking is a factor, and means you power its refresh charge to increased ranges than the producer supposed. It was extra commonplace again within the day earlier than increased refresh charge screens reminiscent of 120Hz and 144Hz screens burst onto the scene, however today it’s nonetheless potential with sure fashions.

The refresh charge of a monitor is what number of instances per second a pixel is rendered, with the usual being 60Hz. With increased refresh charges, the graphics are being rendered on display even quicker than 60 instances per second (reminiscent of 144FPS for a 144Hz display) which might make fast-paced video games like FPS/shooters seem extra easy. Like overclocking any half, there are nonetheless dangers to overclocking your refresh charge past what the display specs are, reminiscent of damaging your display. We do not suggest it, and in order for you the next refresh charge, you must simply purchase a display that has the Hz you are after.

Forcing the next refresh charge isn’t really useful



So, Is Overclocking Definitely worth the Threat?

As talked about, doing an overclock is sort of secure today if in case you have appropriate {hardware} and take it gradual and regular, but whether or not or not it is truly price it’s going to completely rely in your specific parts, efficiency goals, and threat tolerance. With some techniques you won’t get a lot of a efficiency enhance to make it well worth the threat (or to make it price the additional pressure in your elements).

However with the correct system and when carried out proper, overclocking could possibly be a smart transfer to squeeze out a pleasant bit of additional efficiency for little to no additional value (although do not forget that you want a greater cooler, higher case cooling, higher motherboard, and so on). As with most issues {hardware} associated, the reply is identical previous reply that is been repeated for millennium: (and can proceed to be) – it relies upon.

In regards to the Writer

I am Julz, creator of BGC. In my teenagers I realized recreation programming as a interest in my spare time, which led to a eager curiosity within the {hardware} aspect of issues as nicely. I then began this website to share what I used to be studying about DIY on the time, and thru years of trial and error and gradual reiterations within the high quality and depth of content material, over time the location has advanced from a really rudimentary little weblog with solely a handful of pages into a comparatively in-depth useful resource for PC builders and avid gamers that has helped many avid gamers and energy customers make the leap to construct their first PC with confidence to reap the benefits of doing so.

My fav video games of all time are the immortal OOT, Good Darkish, MGS1, MGS2, GE007, DKC2, and HL1, however since attempting VR for the primary time just a few years in the past I have been fully fascinated by it and the limitless potentialities it presents. When you expertise the best digital actuality experiences out there right now like Half Life Alyx and Saints and Sinners simply to call two, if you happen to’re like me you will really feel fairly freakin’ enthusiastic about the way forward for gaming and leisure as an entire.

PS: After an extended hiatus from hobbyist recreation dev, I lately made a return and am excited to say I will quickly be saying my first official recreation launch – an immersive story-driven VR Sci-Fi Journey powered by Unreal Engine. When the time is true I will be saying the primary sneak peak trailer on my Twitter if .
