Safe Voltage for Ryzen: Everything You Need to Know

The AMD Ryzen processor is an outstanding choice for anyone looking to build a new PC or upgrade their existing system. However, before you purchase this gaming beast you must know about the safe voltage for Ryzen.

Around 1.5 volts is considered as the safe voltage for Ryzen however, there are different Ryzen models and each one has slightly different requirements.

As you we’ve already mentioned AMD has produced different models in their Ryzen series to compete with the intel. let’s learn some interesting facts about the AMD Ryzen series and its voltage.

If you are interested then we highly recommend reading this article to the end.


What Does ‘Safe Voltage’ Mean for Ryzen CPUs?

The term ‘safe voltage’ stands for a stable voltage under load condition which ensures that your PC is booting up fine and working stably without any hiccups.

Every PC user wants their processors to be running at their peak performance, but many of us don’t know how to overclock the Ryzen CPU to achieve this goal. On a side note, we have a quick read on how overclocking reduces CPU lifespan. It’s an important one.

If you are one of those who don’t know how to overclock Ryzen then you should know about the safe voltage for Ryzen CPU first, by which you can achieve high overclocks.

Although AMD has not mentioned any specific Voltage range for all their Ryzen CPUs however we have tested different models and below is the safe voltage for the Ryzen CPU range.

Safe Voltage For Ryzen 7/5/3 Processor Models:

If you are using any of the below-mentioned AMD Ryzen CPU models then we recommend you to set your vCore voltage between these ranges.

AMD Ryzen 71.35 to 1.40 Volts
AMD Ryzen 51.31 to 1.36 Volts
AMD Ryzen 31.20 to 1.225 Volts

How to Know The Safe Voltage for Ryzen CPUs?

It does not matter which CPU you are using or what is the model number of your Ryzen processor. All processors have different voltage requirements and some processors even require a little more voltage than others.

However, it isn’t a very simple thing to know as there are a number of factors that come into play when determining the safe voltage for Ryzen CPUs. Below are the main factors due to which the safe voltage of the CPU may vary.

  • Core current
  • Temperature
  • Operating Frequency

Core current

As you know CPUs have different core currents so it’s obvious that cores with lower current require less voltage than those with high power consumption.


When the temperature of the CPU is low, its working efficiency and stability also increase, and thus we can say that the safe voltage for Ryzen becomes higher at low temperatures.

Operating Frequency

The same things happen when the operating frequency of your CPU is higher. So, at higher frequencies and low temperatures you need to increase the voltage for Ryzen CPUs.

What is Drop Off Voltage?

When you increase the voltage of your CPU, it starts producing more heat which can even cause a complete shutdown of your system. Thus, it’s recommended to keep an eye on the drop-off voltage which tells when the CPU is going to shut down due to the lack of cooling.

Drop-Off Voltage = xV Core + 0.2V

Above is the formula for drop-off voltage which tells how much extra voltage you should add to keep your CPU from shutting down due to increased temperature. However, this number varies and a little change in V Core can make a lot of difference.

For example: If you are using a Ryzen 5, then a 1.2V drop-off voltage is enough for a Ryzen 5 to work efficiently in an overclocking state. On the other hand, if you keep this voltage at 1.2V then your CPU might shut down due to temperature issues so it’s better to overvolt it 1-2 notches and test again.

AMD recommends keeping up to 20 degrees C of cooling headroom.

What is The Safe (Drop off) Voltage for Ryzen CPUs

As you know there are different models of the Ryzen CPUs and we’ve already told you that each one may have slightly different requirements. Let’s find out what is voltage offset ryzen CPUs, in order to get a better understanding of this topic.

Max Safe Voltage for ryzen 3600X

If you are using the ryzen 3600X CPUs then you should not increase vCore voltage above 1.36 volts even if your temps are low or frequency is high.

Why? Because this CPU has a high core current and if you increase the ryzen 3600 safe voltage value beyond 1.36 volts then it may permanently damage your processor.

Now what you should do is to reduce the CPU voltage slightly so that you can achieve a stable overclock without causing damage to your Ryzen 3600X.

One thing you must keep in mind is that the damages which occur to your processor will be permanent therefore, you need to be extremely careful during the overclocking process.

Speaking of the safe voltages and stuff like that, you should also have a look at realtemp vs coretemp in order to get a better understanding.

Max safe voltage for ryzen 5600x

If you are using the Ryzen 5600X CPUs then your safe voltage range is between 1.25-1.30 volts, so we recommend that you do not go beyond these values because it may permanently damage your CPU.

Max Safe Voltage for ryzen 5 2600

We have tested the Ryzen 5 2600 processors and found that their max safe vCore voltage range is between 1.2-1.32 volts therefore, we recommend to stay within this range in order to avoid permanent damages which can occur due to high voltages.

Max safe voltage for ryzen 7 3700x

The Ryzen 7 3700X is the flagship CPU of AMD’s second-generation ryzen lineup and like other 3000-series CPUs, it also requires a lower voltage than its predecessors. Finding safe voltage for ryzen 7 3700x can be tricky but still possible and we’ve already found it for you.

We have tested this processor and found that the max safe vCore voltage range for Ryzen 7 3700X processors is between 1.25-1.375 volts, so we recommend staying within these values in order to avoid permanent damages which can occur due to high voltages.

Max safe voltage for ryzen 5 3600

One thing you should keep in mind about the Ryzen 5 3600 which is AMD’s latest Hexa-core CPU is that its operating frequency increases exponentially as the temperature decreases therefore if you are using this CPU then you should set the vCore voltage to 0.01 volts higher for every degree reduction in temperature.

Now it is pretty clear from the explanation before this that if you want to make your computer go fast, then you need more voltage. But if you use too much voltage, it will be bad for your computer. So don’t use more than 1.4 volts of vCore on these CPUs, unless you are really trying to make them go fast.

Max safe voltage for ryzen 5 2600

AMD Ryzen 5 2600 is a Hexa-core CPU with 12 threads and the max safe voltage range for this CPU is between 1.25-1.275 volts, so we recommend going within these values in order to avoid permanent damages which can occur due to high voltages.

Max safe voltage for ryzen 5900x

The safe voltage for the Ryzen 5900x is between 1.25-1.3 volts, Because of the potential risks of using extremely high voltages, we advise staying within these limits to minimize long-term damage.

Max safe voltage for ryzen 5000

The Ryzen 5 CPUs are built upon a 12nm process design and their maximum safe voltage range is between 1.2-1.4 volts. Thus you should never exceed this limit no matter how much you need it because things can go pretty bad for you.

Max safe voltage for ryzen 5 1600

Likewise, the Ryzen 5000 safe voltage range is between 1.2-1.45 volts. Staying in this range will keep your processor safe and it will provide its maximum performance during and after the overclocking process without getting toasted.

How do I know if my CPU is unstable?

You can know more about your CPU’s stability by using the Ryzen Master software which has features such as temperature monitoring and voltage monitoring.

If you want to monitor your CPU voltage in real-time, then you can use HWINFO64 for this purpose. This free piece of software is great because it tells you exactly what your vCore, temps, and other things are.

Frequently Asked questions

How to set the voltage for the CPU?

Setting the Voltage for the CPU is easy and can be done through dedicated software. You can just go to Ryzen master and then you set the value in the CPU core voltage section.

How much voltage is for the CPU?

CPU’s Max safe voltage range is between 1.2-1.45 volts, and the optimal value within this range is the safe CPU voltage ryzen.

How to know my CPU max vcore?

First, you need to check with Ryzen master or HWINFO software after opening them you can see certain values such as vCore. You can also disable all the power-saving features in the BIOS. Once you have disabled them you can then see your CPU max vcore.

How much voltage is too much for a CPU?

Just as we’ve mentioned many times above in our guide, you should give 1.45 volts at max to your computer’s processor and that too after checking different conditions. You should never exceed 1.5 volts because this is the limit and exceeding this limit will most probably result in the toasting of your CPU.

Final Words

We did some research on the safe voltage for ryzen processors but to our surprise, we couldn’t find actual voltage values from any authentic sources such as AMD’s own website.

It took us days of research but thanks to computer geeks out there who love performing different kinds of experiments. During our study, we were able to know that the safe voltage for ryzen CPUs is 1.5 volts at max and it should never be exceeded beyond this value.
