 AMD’s newest Ryzen CPUs are blisteringly fast—a testomony to the corporate’s momentous slingshot again to the forefront of chip growth. However that is not at all times sufficient for these of us with a screwdriver and a dream. We would like extra. And to do that you will must discover ways to overclock an AMD Ryzen CPU like the professionals.

Overclocking is basically fairly a easy act: you are pushing your processor past its rated limits for greater efficiency. To attain this, you will must reap the benefits of any latent efficiency leftover from the imperfect chipmaking course of—not each chip is made equal, and a few could have greater thresholds than others for pushing energy and thermal calls for. That is what we name the silicon lottery—receiving a chip able to cruising previous inventory speeds is similar to a profitable ticket.

There are a number of methods to overclock your AMD CPU: you’ll be able to allow AMD’s Precision Enhance Overdrive 2; hop into the the Ryzen Grasp Utility, or the most recent Radeon drivers; or head to the BIOS and tweak nearer to the steel. If none of these suffice, there are nice third-party overclocking instruments to get probably the most out of your chip at a extra granular stage. All of which ought to enhance your CPU efficiency. 

That mentioned, these days AMD is operating its Ryzen CPUs a lot nearer to their restrict out of the field. So whilst you may have the ability to squeeze a contact greater frequencies out of a single core, CCX, CCD, or entire CPU, it is unlikely you’ll break any lofty velocity data with out some liquid nitrogen and a dying want in your PC’s elements.

It is all nonetheless to play for, although, and there may be advantages to overclocking your chip with out placing its life in jeopardy. Simply comply with these easy steps to a speedier AMD Ryzen CPU.

What that you must overclock your AMD Ryzen CPU

AMD leaves the door broad open for avid gamers to overclock their Ryzen CPUs, and you will find much less stringent guidelines for overclocking in comparison with Intel’s lineup. That mentioned, there are nonetheless just a few belongings you’ll want with a view to get an overclocking up-and-running. 

  • A appropriate motherboard. AMD helps overclocking on all of its Ryzen CPUs however not each motherboard does. The next motherboard chipsets assist overclocking: X570, B550, B550A, X470, B450, X370, X300, B350. Try the greatest AMD motherboards for our suggestions if that you must decide one up.
  • An honest CPU cooler. Whereas it is unlikely you’ll push your CPU a lot additional than its acknowledged limits, overclocking will improve the facility calls for, and due to this fact thermal output, of your processor. Which means you will want a CPU cooler that may deal with greater than your chip’s rated TDP. Most highly-rated liquid all-in-one coolers ought to do the trick, as will bigger air coolers.
  • CPU monitoring software program. With a view to be certain your CPU is operating at greater frequencies and doing so at an appropriate temperature, you will want some type of monitoring software program. HWMonitor is our go-to, together with HWInfo, MSI Afterburner. AMD’s personal Ryzen Grasp Utility can be a great decide. Some peripheral software program additionally affords this data, so use whichever you discover best to report temperature, energy, and clock speeds.
  • Inventory benchmarks. If there’s one factor I’ve forgotten to do all too usually when overclocking my CPU, it is accumulate some efficiency figures earlier than I begin. Do that, and it is possible for you to to see in case your overclock on the finish of this course of is definitely netting you any precise efficiency achieve. As a result of that is what we’re actually doing it for, proper?

It is also good to have a benchmarking and stress testing software program at hand to verify your overclock is secure. Some common decisions embrace: Cinebench R23, 3DMark Time Spy, AIDA64, x264 HD, and a number of at present’s common and demanding video games. You simply need to watch out along with your alternative right here—Prime95 is a well-liked CPU stress testing software program however it could actually put your CPU below excessive duress, which can result in some uncomfortable temperatures and voltages over time.

That’s the level of stress testing software program, although.

It comes down to private choice. You is likely to be joyful operating a few video games to examine your overclock is secure sufficient in your wants, whereas another person may choose to push it to the bounds to make sure it is rock strong it doesn’t matter what will get thrown at it. You actually simply need to make certain that your PC is not going to show itself off throughout your regular day-to-day utilization, no matter which means for you.

PLEASE NOTE: All the next overclocking methods, together with Precision Enhance Overdrive 2, will void your CPU’s guarantee. That does not imply they’re essentially harmful over the long term—CPUs are likely to deal with themselves with intelligent failsafes these days—however do watch out when adjusting any of your CPU’s operational settings to make sure a easy overclocking course of and lengthy lifetime of your elements.

Methods to overclock your AMD Ryzen CPU 

Soar forward to the overclocking information that fits you with the hyperlinks beneath, or scroll down to begin proper at first. 

Precision Enhance Overdrive 2

  • Execs: Simple to implement, longer sustained clock speeds
  • Cons: Would not improve max clock velocity, voids CPU guarantee

One of many quickest and best methods to run your Ryzen CPU at greater sustained frequencies than at inventory is to enabled Precision Enhance Overdrive (PBO). That is PBO2, in reality, these days, which is a brand new and improved model of the auto-boost software out of the crimson staff.

That is proper, PBO2 is an official software, and whereas AMD nonetheless warns in opposition to potential danger when utilizing it, it is likely one of the extra risk-averse methods to enhance your CPU’s efficiency.

So what’s PBO2? It is an automated and adaptive one-click software to spice up efficiency. It’s primarily an extension of Precision Enhance 2, which is AMD’s enhance algorithm liable for making certain your CPU manages to hit its most clock velocity throughout operation.

It is also not technically overclocking your chip. At the least not within the sense that you just’re forcing the processor to run at the next than inventory clock velocity. What PBO2 does is enable your chip extra energy to run at its enhance clock for an extended sustained interval or time, thus enhancing efficiency. 

So PBO2 achieves what lots of you is likely to be in search of no matter its lack of OC credentials.

A screenshot of an MSI motherboard BIOS with PBO2 menu on screen

Some motherboards supply a number of choices for PBO2, however you’ll be able to simply hit ‘Enabled’ and be achieved with it. (Picture credit score: Future)

PBO2 is simple sufficient to allow within the BIOS, which is how we advocate you go about setting it up. You may often discover this setting inside superior overclock settings, possible below ‘AMD overclocking’. The good thing about enabling it within the BIOS is that your motherboard might be able to overrun AMD’s traditional presets, providing you extra management over PBO2 parameters, together with undervolting. To not point out BIOS choices appear rather less transient than desktop software program.

Ryzen Grasp is a free obtain accessible on the AMD web site and a superbly viable possibility all the identical. All that you must do to get began is open the software program, hit superior, navigate to both Profile 1 or Profile 2 on the left-hand facet, and allow Precision Enhance Overdrive from the highest choices bar.

Whichever you select, your system ought to set three parameters above the default specification as soon as PBO2 is enabled:

  • PPT – Whole Socket Energy
  • TDC – Sustained Present Restrict
  • EDC – Peak Present Restrict

Ryzen Grasp affords an in depth breakdown of all of the settings you will must tinker with to overclock or enhance your CPU. (Picture credit score: AMD)

These values are ruled by your alternative of motherboard. Some motherboards with high-end VRM and energy supply elements will probably be rated to a lot greater values than others, and which means they’re comfy, or not less than must be comfy, with sustaining that type of energy for longer.

It is value mentioning that you may additionally undervolt your CPU to attain even decrease energy consumption and your chip’s thermal qualities. Soar all the way down to the undervolting your CPU part for extra.

General, although, the profit to PBO2 may be dependent in your motherboard and its elements, in addition to your CPU’s roll of the silicon cube and leniency for greater energy limits. It is also stored in examine by the parameters measured by Precision Enhance 2, reminiscent of temperature, workload sort, lively core depend, and most enhance frequency.

To transcend these specs, you will want to take a look at utilizing PBO2 in tandem with AMD’s auto-overclocking characteristic, undervolting, and even handbook overclocking.

However earlier than we transfer on, you will need to stress check your overclock when you assume you have bought an honest one in place. Soar all the way down to the testing your overclock part for extra data on how to try this.

Computerized overclocking

  • Execs: Easy, works with PBO2, will increase max clock velocity
  • Cons: Be careful for prime voltages, voids CPU guarantee

It is fairly easy to robotically overclock your chip from inside your BIOS or by AMD’s Ryzen Grasp Utility software program. It is a free software program obtain accessible on the AMD web site, and it accommodates every part that you must monitor and manipulate your CPU’s operation.

AMD’s automated overclocking builds upon the PBO2 enhance mentioned within the earlier part, and makes an attempt to mix PBO2 with a manually assigned offset to the utmost enhance clock of a processor.

To enabled automated overclocking within the BIOS, head to the superior overclock settings, often below ‘AMD overclocking’ and allow PBO2. In contrast to in PBO2 information, although, we’re additionally going to regulate the Max CPU enhance clock.

A screenshot of an MSI motherboard BIOS with max boost clock setting highlighted

You solely want modify this one additional setting on prime of turning on PBO2 to permit your chip to exceed its inventory clocks. (Picture credit score: Future)

To allow auto-overclocking in Ryzen Grasp, head into the superior settings within the app. There’s a shortcut on the simplified popup window, if most well-liked, but it surely’s truly simpler to get a way of what is going on on from the superior window. From there, head to Profile 1 or Profile 2, the place you are free to tinker along with your CPU’s settings.

Tick the Auto Overclocking field from the Management Mode choices bar (a restart will probably be required), and 4 parameters will probably be set inside app. These are:

  • Enhance Override CPU – the megahertz worth which you intention to extend your CPU’s most enhance clock
  • PPT – Whole Socket Energy
  • TDC – Sustained Present Restrict
  • EDC – Peak Present Restrict

So the identical as PBO2 besides with the added capability to extend the utmost enhance clock your chip can intention for throughout operation. This worth just isn’t a mandate, nevertheless, and your chip won’t essentially hit it at any time. So greatest to be practical and set this to a few hundred megahertz, max.

For instance, a Ryzen 9 5900X is rated to 4.8GHz max clock velocity out of the field. A totally comprehensible aim could be to intention for a lofty 5GHz, and to take action it would be best to set a 200 worth in Enhance Override CPU. That units the CPU’s most enhance frequency to 5GHz. If you wish to hit 5.1GHz, set this to 300MHz, however that is already fairly optimistic.

You’ll be able to crank up the Enhance Override CPU setting to whichever worth you need, it does not imply your CPU is definitely going to hit that worth throughout operation. (Picture credit score: AMD)

The PBO2 values are additionally a bit of extra vital with regards to auto-overclocking, since you’re now attempting to hit the next goal frequency. Which means it’s possible you’ll discover your CPU makes use of extra energy funds typically use, which could have a knock-on impact on thermals and noise ranges.

You’ll be able to examine to what extent your CPU is gobbling up its energy budgets on the House display within the Ryzen Grasp software program. It is good to regulate these throughout testing to make sure you’re pleased with the typical values.

As soon as once more, although, you are free to undervolt your CPU to try to decrease your voltages, and one of the best bit is you’ll be able to string collectively PBO2, the automated overclock, and undervolting to create a system that truly runs quicker and at decrease voltages than its inventory compadre.

That is automated overclocking, anyhow. And once more you will need to stress check lots earlier than calling it a day.

Now let’s get onto the extra advanced matter of handbook overclocking.

Handbook overclocking

  • Execs: Tons of choices, extremely customisable
  • Cons: Static, does not supply big real-world features, straightforward to interrupt stuff

Handbook overclocking is the ‘old fashioned’ approach of doing issues, but it surely’s additionally usually helpful for pushing your processor past its limits—if what you are doing. It is vital to strategy manually overclocking with a measured and gradual strategy, not solely to seek out your CPU’s candy spot but additionally to maintain from zapping it with extreme voltage.

That is why we advocate the 2 approaches outlined above earlier than tweaking issues manually. That is not solely as a result of it is probably extra harmful, you have to throw warning to the wind and reside a bit of each now and again, however as a result of AMD Ryzen CPUs are very effectively optimised by AMD, and so adaptive algorithms are likely to get extra out of Ryzen CPUs than a gentle all-core overclock.

However let’s get on with how one can obtain that in case you so want. And because the introduction of Zen 2 processors, the Ryzen 3000-series, AMD Ryzen overclocking has grow to be about not solely overclocking your chip, however overclocking your chiplets. That is a probably thrilling prospect, as every chiplet (generally known as a CCD) affords one other likelihood to win on the silicon lottery.

However I am getting forward of myself. Let’s get into the precise overclocking course of, which may be achieved manually by way of your motherboard’s BIOS (the standard approach) or the Ryzen Grasp Utility.

Let’s keep on with the old fashioned approach and head to the BIOS. This course of will look barely completely different relying on the producer of your explicit motherboard. However that mentioned, I’ve by no means seen one that basically shakes issues up an excessive amount of, so I will try to maintain issues common from right here on out. It can even be fairly straightforward to match up what I am saying contained in the Ryzen Grasp software program, too.

MSI motherboard BIOS with CPU ratio setting highlighted

Crucial setting for adjusting your goal clock velocity is CPU Ratio, usually known as the multiplier. (Picture credit score: Future)

To get into the BIOS, you will need to mash the Del key through the PC boot course of. If that does not work, strive F2 or Esc. It ought to say on the backside of the display throughout POST what to press both approach.

As soon as into the BIOS, you will need to head to the overclocking choices. You might have to enter Superior mode for this, which ought to have a keyboard shortcut related to it clearly marked on the BIOS display. On our MSI X570 Godlike motherboard that is F7.

Throughout the overclock settings display you will discover your BCLK frequency and your CPU Core Ratio:

  • BCLK stands for base clock, and it isn’t solely vital in your CPU clock, but additionally different capabilities of your motherboard, RAM, and PCIe bus. The BCLK acts as the elemental marker of clock velocity in your system, and most different clocks are primarily based on a multiplication of it. Don’t fret, we’d like solely work out some easy maths for our functions at present, and to make life simpler your BCLK will possible be set to 100MHz by default. This worth may be adjusted for small will increase in clock velocity, however since these changes may also have a domino impact on the clock velocity of different elements, not simply the CPU, we’ll go away it as is.
  • CPU Core Ratio (usually known as a multiplier) corresponds on to the clock velocity of your CPU, as a multiplication of the BCLK. It can possible be set to auto by default, which is able to hand away management of this ratio to varied different algorithms behind the scenes, however for the needs of our overclock we need to set this to a gentle worth. The worth we set right here is the multiplication of the BCLK that we wish our CPU clock velocity to be, i.e. a CPU Core Ratio of 40 would lead to a CPU clock velocity of 4,000MHz (40 x 100MHz = 4,000MHz).

To work out your goal CPU Core Ratio, then, it is easy:

Goal clock velocity (MHz) / 100

It is not a case of choosing any worth in your CPU Core Ratio, nevertheless. Set this too excessive and you will find your CPU will not boot accurately, and can possible kick you again to the BIOS for one more go at a decrease clock velocity.

An MSI motherboard BIOS with BCLK setting highlighted

You needn’t mess with the CPU base clock all that a lot, until you actually need to dive proper in to extra advanced overclocking. (Picture credit score: Future)

So contemplate small increments when growing your Core Ratio. This manner, precisely the place the restrict is in your processor, and precisely once you hit it. I like to recommend you retain your telephone or a notepad shut by to jot down what Core Ratio works and what does not, and the identical goes for voltages.

Voltages are the second piece of the overclocking puzzle, as a result of what a CPU is likely to be not capable of obtain at inventory voltages, it might be able to with a bit of extra energy surging by its transistors.

If you cannot fairly discover a secure Core Ratio that you just’re pleased with, you may need to contemplate bumping up your CPU’s voltage (VCore). On the flip facet, in case you’re discovering your system is secure at a great clock velocity you are pleased with already, you possibly can contemplate dropping your CPU’s VCore to undervolt your processor.

Phrase of warning: altering your CPU’s VCore is likely one of the extra harmful issues you are able to do in your system’s BIOS, so for the protection of your chip, stick inside cheap limits.

An MSI motherboard BIOS with CPU voltage settings highlighted

You may need to mess around with the CPU Core Voltage setting to make sure a secure overclock. Try to keep away from a 1.4V VCore just like the displayed right here.  (Picture credit score: Future)

For an AMD Ryzen CPU, the cheap vary of VCore is round 1.35v. Some say you’ll be able to push nearer to 1.4v, however you are pushing up into a spread that would trigger injury to your processor over time, so achieve this at your personal danger. Bear in mind the upper you improve your voltage, the higher your cooling answer will have to be to keep up comfy temperatures of beneath 80–85°C.

So you have bought your clock velocity and your voltage all seemingly working accurately? You can go away issues there and transfer on to testing your overclock, and in reality that is a fairly good approach to go about issues even in case you do find yourself coming again thus far I am about to make: You’ll be able to inform your processor to run at an offset voltage.

An MSI motherboard BIOS with CPU voltage settings menu highlighted

(Picture credit score: Future)

It is good to do as soon as your comfy working voltage, however after getting it you’ll be able to check out permitting your CPU to drop the voltage when it isn’t required, reminiscent of when it is in an idle state. To take action, set your CPU VCore to offset mode, change the offset signal to unfavourable, and set the vary to which your CPU can decrease the voltage to.

These are nonetheless simply the fundamentals of overclocking, and also you may need to take into consideration diving into additional optimisations reminiscent of load line calibration to take your overclock that one step additional. What’s right here will web you a snug overclock although, however not earlier than you have achieved some stress testing to verify it will not be shaken unfastened anytime quickly. 


Okay, I’ve talked about undervolting lots however now it is time to truly inform you do it.

By means of the BIOS you’ll be able to truly set PBO2 to undervolt your CPU with a view to working your CPU at decrease voltages whereas retaining the identical efficiency, and even enhancing it with automated overclocking. All of which saves on energy consumption, waste warmth technology, and extra noise.

You may discover the choice to undervolt your chip below Curve Optimiser in your BIOS overclocking settings. To seek out it, I needed to flip PBO2 to ‘Superior’ after which dive into the menu from there. 

An MSI motherboard BIOS with Curve Optimiser all-core settings highlighted

You’ll be able to merely set an all-core optimisation right here, just like the gentle undervolt set within the picture above. (Picture credit score: Future)

As soon as you have discovered it, you will need to set the All Core Curve Optimiser signal to unfavourable to realize an undervolt. You’ll be able to go away the Scalar to Auto.

With each increment of the All Core worth to the max depend worth of 30, you are primarily adjusting the voltage to clock velocity curve of your CPU—telling it to run at a decrease voltage for a given clock velocity, or, in case you have a look at it one other approach, telling it to run at the next clock velocity for a given voltage.

From right here, although, you’ll be able to additional undervolt on a per core foundation, additional optimising the voltage curve to your particular chip. It is likely to be good to take a look at Ryzen Grasp right here, which provides you a primary and second greatest score in your CPU’s cores, which ought to deal with being undervolted additional than others.

An MSI motherboard BIOS with Curve Optimiser per-core settings highlighted

If you wish to get extra particular, you’ll be able to set the Curve Optimiser on a per-core stage. (Picture credit score: Future)

You may additionally discover you’ll be able to apply an automated overclock on prime of your undervolt for optimum efficiency with decrease energy consumption. To take action, merely set it such as you would within the automated overclock part above, by heading again a menu within the BIOS and enabling an offset to the Max CPU enhance clock.

You may need to be testing your system for stability right here each step of the way in which, although, so let’s check out how greatest to go about that.

Testing your overclock

Like I discussed approach up prime, it is vital to select a monitoring software program that provides you all the knowledge that you must precisely monitor your CPU’s operation. 

HWMonitor is a strong decide, as is HWInfo. Truthfully, I usually confuse the 2, they’re so comparable. MSI’s Afterburner is often a GPU overclocking software, but it surely additionally affords CPU monitoring graphs within the prolonged drop-down view which may be actually useful to see how your CPU ramps up and down over time.

For probably the most half, you will desire a fast and soiled benchmark that can put respectable load in your CPU to examine it isn’t going to crash and burn. There isn’t any must run by the prolonged benchmarking course of each time in case you a brief run will show your overclock unstable immediately. Cinebench R23 is a fairly fast one for that function, and in case you hit the superior possibility within the menus you then’re capable of run each multi-core and single-core exams. With this, you’ll be able to see not provided that your CPU is secure, however below load what clock speeds it’s managing to achieve.

Maxon Cinebench R23 mid-run with an AMD Ryzen Threadripper chip

A few Cinebench runs ought to offer you a transparent thought of whether or not your overclock has any likelihood of sticking. If it passes, you will need to put it by its paces with extra taxing testing. (Picture credit score: Maxon)

A single run of Cinebench is not going to show your system secure for lengthy durations, although. You can strive Cinebench’s stability check for half-hour for that, however you may as well use both an app known as AIDA 64 or one known as Prime95. 

Be warned, these are stress exams by identify and stress exams by nature, so they need to actually solely be used to verify your system is as much as day by day use and never for too lengthy.

What you are in search of when testing an overclock, firstly, is that your PC does not flip off, restart, or BSoD through the check. That often means one thing is awry. On this case, it is time to head again to BIOS or Ryzen Grasp and check out a decrease clock velocity or the next voltage—inside motive, after all.

The opposite factor to be looking out for are excessive temperatures, excessive voltages, or unusual CPU behaviour. So regulate your monitoring software program of alternative, measure max and common metrics, and be sure to’re not pushing your CPU too far for an every single day overclock.

A screenshot of AIDA64 in action.

There are a number of methods to emphasize your system in AIDA64, simply watch out to not overdo it.

Bear in mind, generally these previous couple of megahertz will not translate into any efficiency in anyway, however your CPU may demand a lot greater voltages with a view to attain such lofty clock speeds. You do not need to push your CPU for no motive, and overclocking for on a regular basis use is extra of a query of real-world features than it’s about chasing greater and larger numbers.

Depart that to the professionals.

Since that is PC Gamer, we’re actually chasing gaming body charges. A GPU overclock will web you far more in that division, however let’s not write off the CPU OC but. Play just a few video games to examine stability after which seize some matching benchmark numbers to these you bought approach again at first of this course of—I informed you they’d come in useful.

In case your system is secure and your body fee greater, congratulations, you have overclocked your CPU. In case your system is secure however your body fee is similar, effectively, that is not all that unusual for an AMD CPU these days, however not less than you’ll be able to most likely run at a decrease voltage. 

And if it is unstable and your body fee worse, effectively, it is again to the start with you.
