ddr4 1.2 v vs 1.35 v

DDR4 1.2v VS 1.35v – The Answer Varies User to User

Confusion can make an obvious decision baffling.

1.2 and 1.35v!

The voltage difference between these two DDR4 RAM is only 0.15v. And, it’s this tiny difference that makes choosing between the RAMs’ a daunting task.

So, which one is better in DDR4 1.2v vs 1.35v?

In DDR4 1.2v vs 1.35v, 1.2v is the standard operating voltage for DDR4 RAM with better temperature stability. Whereas, 1.35v DDR4 is factory overclocked and comes with unstable operational temperature. Yet again, DDR4 1.35v has the ability to run higher power applications which 1.2v DDR4 lacks.

Now, which one to choose between two? Here we have compared the features of those RAMs in detail. This will help you choose the perfect RAM.

So, let’s get started!

Does RAM voltage matter?

Yes, RAM voltage matters. For most modern CPUs, the memory controllers are designed for working in low voltage memory. This helps prevent long-term damage to the CPU. But overclocking upto a certain voltage for faster work is applicable.

The standard voltage of DDR4 RAM is 1.2v. But the voltage can be overclocked for workload demand. The limit should be 1.4v for the longevity of RAM and to avoid any risk.

Short Comparison: DDR4 1.2v vs 1.35v

To improve the system’s performance, the best solution is to upgrade the laptop memory.

Here, DDR4 1.2v and DDR41.35v are both standard voltage RAM. But they have certain features that make the difference.

Let’s take a look at them

Detailed Comparison 

Knowing the differences itself isn’t enough.

To distinguish them, you need to know more details. This will help you know their functions and relate to your choice of work. 

Off we go to know more about it-

Overclock:

In ddr4 1.2v ram, it is possible to overclock up to 1.4v max. Because this keeps the temperature low. But there are some motherboards that do not support high memory voltages.

Here the question arises, is 1.4v safe for DDR4? Yes, it is. Some memory module kits run up to 1.35v with XMP. Going above 1.4v isn’t always safe. Until the system is stable, raising the voltage slowly is recommended.

After a certain time, the RAM won’t boot when pushing the voltage too high. In that case, try a lower voltage.

Whereas, 1.35v is factory overclocked. Overclocking the RAM will increase the temperature and damage it. In that case, a RAM cooler is required to cool down the temperature.  So, overclocking will not be possible with 1.35v just as 1.2v.

So, 1.2v takes the round.

Application Usability:

DDR4 1.2v is for low-power applications found in laptops. Web, office and media Programs don’t take excess power or speed for even normal usage.

Here’s the power consumption for 1.2v DDR4 RAMs.

But Graphics designing tools, Software Development tools, and 3D animation software need higher voltage. Besides, multiple monitors require additional ram with high voltage. Especially if you are a designer. 

So, for a graphics designer 1.35v, DDR4 RAM would be a better choice rather than 1.2v. Because higher voltage will be able to release a higher amount of energy a lot quicker.

1.35v DDR4 takes over this round!

Speed:

Higher voltage RAM has more BUS speed which leads to faster data transfer. While doing graphics designing, 3D animation, or playing video games higher speed is needed.

In that case, you can pair your PC with ddr4 3200 1.35v. Whereas, you’re limited to 2666mhz with 1.2v ddr4 RAM. So, 1.35v will be more efficient than 1.2v ddr4.

Here ddr4 1.35v wins. You can look into The Oloy DDR4 RAM. However, if you need a single 8 gb stick, you can see Timetec 8GB DDR4 3200MHz.

Video editing:

For smooth video editing, the PC requires enough memory available for the operating system. Including the computer’s background tasks to continue working.

The minimum capacity for RAM used for video editing is 8GB. This is approximately 1.2v. Well, it won’t be necessary to have an optimized RAM from AMD.

But technically 16GB is better for smooth video editing and letting the background task continue.  But professionals should consider 32 GB. Besides, it is enough for editing 1080p projects or 4k files within minimum effects. 16 GB is approximately 1.35v.

Here’s again 1.35v wins!

Stability: 

As mentioned before, 1.2v is a standard voltage whereas 1.35v is technically overclocked. 

It is possible to overclock 1.2v ddr4 slowly keeping the temperature under control. On the other hand, 1.3v has to be cooled down. 

Here, the temperature stability of 1.2v is more than 1.35v.

Therefore, 1.2v is the winner. In that case, you can look into the Corsair 4GB DDR4 1.2V.

Price:

Average price of ddr4 1.2v RAM is $100-$120 and $160-$175 for 1.35v. If you do not intend to do graphics design, animation, or any other high voltage work, 1.2v ddr4 will be a good choice.

But ddr4 is basically for high power and energy work. As higher voltage is necessary for higher video editing, buying 1.34v with a higher price is worth it.  

Here again, 1.35v wins!

Well, these were the Factors that differ from the DDR4 3.5v Vs DDR 1.2V

Which One to Buy?

After the overall comparison, it’s time to decide which one would be wise to choose?

Fundamentally, both RAMs’ are great to use. But their functionality slightly differs. Among them, the notable differences are overclocking, temperature stability, and the speed of transferring data. 

Now the question is – “Is 1.35v good for RAM?” Yes, low voltage RAM is good if the task isn’t high loadable. If you’re up for high power, faster speed, and more application usability, buy DDR4 1.35v.

Along with regular tasks, this RAM especially helps to do video editing, graphics designing, 3D animation, web designing, etc

Now the second question is – “Is 1.2 v enough for RAM?” Yes, it is. But 1.2v DDR4 RAM is used for less power-hungry applications.

Like the Web browsers, Office Programs, and Media Programs

As the temperature remains stable, overclocking is possible when required. So, if you do general power work, it’d be wise to buy DDR4 1.2v. 

Frequently Asked Questions (FAQS)

Can 1.2 v RAM replace 1.35 V?

Yes, 1.2v can be replaced by 1.35v. But that won’t be wise because 1.2v can be overclocked keeping the stability of temperature. But 1.35v is more likely to get hot faster. Unless you need to do higher efficiency work, don’t replace 1.2v with 1.35v.

Is it safe to overclock RAM?

Overclocking RAM isn’t risky. It is safe unless it exceeds the overclocked limit. After that RAM does not overclock and responds to the system.

Conclusion

So, that’s all about DDR4 1.2v and DDR4 1.35v.

Basically, the voltage in RAM decides the speed and frequency of data transfer

For which choosing a high voltage RAM is beneficial. 

Moreover, faster RAM will improve your lows. It’ll create a more consistent gaming experience for you.

Have fun jamming!
