Difference between 1.2V And 1.35V DDR4 RAM

Last Updated on November 6, 2022 by Tech Questions

There is a big difference between 1.2V and 1.35V DDR4 RAM. The lower voltage RAM uses less power, which can lead to better battery life on laptops and other portable devices. It also runs cooler, which can extend the lifespan of the RAM chips.

However, the lower voltage RAM is not compatible with all motherboards and may require special BIOS settings. The higher voltage RAM is compatible with all motherboards and does not require any special BIOS settings. It uses more power than the lower voltage RAM, but it also runs faster and has better overclocking potential.

It is often said that there is no difference between 1.2V and 1.35V DDR4 RAM. However, there are some key differences that should be considered when making a decision about which type of RAM to purchase. 1.2V DDR4 RAM is typically faster than 1.35V DDR4 RAM.

This is because the lower voltage allows for more speed and stability when operating at higher frequencies. 1.2V DDR4 RAM also uses less power than 1.35V DDR4 RAM, which can be important for devices that are battery-operated or have limited power sources. 1.35V DDR4 RAM may be a better choice for applications that require high data rates or large volumes of data to be processed quickly.

It is also important to consider the compatibility of your device with the different types of RAM before making a purchase.

What is the Difference between 1.2 V And 1.35 V RAM?

There are a few key differences between 1.2V and 1.35V RAM. The most notable difference is that 1.2V RAM uses less power, which can lead to decreased battery life in laptops and other devices. Additionally, 1.2V RAM typically has lower performance than 1.35V RAM due to its lower voltage.

Another key difference is that some motherboards may not support 1.2V RAM, so it’s important to check compatibility before purchasing any new memory modules.

Can You Mix 1.2 V Ram And 1.35 V RAM?

There’s a lot of confusion out there about mixing different types and voltages of RAM. So can you mix 1.2V RAM and 1.35V RAM? The answer is depends on your motherboard and what it’s compatible with. Some motherboards will automatically adjust the voltage for you, while others will not work if the voltages are mismatched.

If you’re unsure, it’s always best to consult your motherboard manual or manufacturer to see what they recommend. That said, mixing different types of RAM isn’t generally recommended as it can lead to compatibility issues down the line. So if possible, stick with one type of RAM for all your slots.

Is 1.35 Volts Good for RAM?

There’s a lot of misinformation out there about what voltage is “safe” for RAM, and it seems like every few months, someone re-opens the question. So, let’s set the record straight: is 1.35 volts good for RAM? The answer is a qualified yes.

While 1.35V is technically within the JEDEC specification for DDR3 voltage (1.5V), going any lower carries some risks. That said, plenty of people are using 1.35V RAM without any issues whatsoever. The main risk of running your RAM at 1.35V is that it may not be as stable as higher-voltage RAM.

This can manifest itself in occasional crashes or freezes, or in more serious cases, data corruption or hardware damage. That’s why we only recommend running 1.35V RAM if you’re willing to accept these risks. If you do decide to run 1.35V RAM, make sure to use high-quality modules from a reputable manufacturer.

Which is Better RAM 1.35 V Or 1.5 V?

The answer to this question depends on what type of RAM you are using. If you are using DDR3 RAM, then 1.5V is the standard voltage and you should use that. However, if you are using DDR4 RAM, then 1.35V is the standard voltage and you should use that instead.

1.35V RAM in 1.2V Slot

If you’ve ever tried to put a 1.35V RAM module into a 1.2V slot, you know that it doesn’t work. The two voltages are not compatible and the RAM will not function properly in the lower voltage slot. However, there is a way to make it work.

By using a simple voltage divider circuit, you can step down the 1.35V to 1.2V and use your RAM in the lower voltage slot. Here’s how it works: 1) Solder a resistor onto each of the RAM module’s power pins.

Use different values for each pin (eg. 10kΩ on one pin, 15kΩ on another). 2) Connect the ground wire from each resistor to the ground pin on the motherboard’s RAM slot connector (there should only be one). 3) Now plug in your modified RAM module into the motherboard’s RAM slot connector.

1.35V Vs 1.5V Ram DDR4

When it comes to comparing 1.35V vs 1.5V RAM DDR4, there are a few key things to keep in mind. First and foremost, 1.5V RAM will require less power to operate than 1.35V RAM. Additionally, 1.5V RAM is typically faster and more stable than its lower voltage counterpart.

However, it’s important to note that not all motherboards are compatible with 1.5V RAM – so be sure to check your motherboard’s specifications before making a purchase!

Does Ram Voltage Matter

Voltage is one of the most important factors to consider when purchasing RAM. It is also one of the most misunderstood and often misinterpreted specifications. The voltage specification for a given type of RAM represents the maximum amount of power that can be safely applied to the chips without damaging them.

However, this number is not always an accurate indicator of how much power the RAM actually uses. Different types of RAM use different voltages. For example, DDR2 SDRAM has a voltage specification of 1.8 volts, while DDR3 SDRAM has a voltage specification of 1.5 volts.

This difference is due to the fact that DDR2 SDRAM requires more power to operate than DDR3 SDRAM. As a result, applying too much power to DDR2 SDRAM can damage the chips, while applying too much power to DDR3 SDRAM will simply cause it to consume more power without any adverse effects. So does ram voltage matter?

In short, yes it does! Applying too much power to your RAM can damage the chips, so it’s important to select RAM with a voltage specification that matches your needs.


1.2V and 1.35V DDR4 RAM have different operating voltages, with 1.2V being the standard voltage and 1.35V being the low-voltage version. The main difference between these two types of RAM is that 1.2V DDR4 RAM is faster and has lower power consumption than 1.35V DDR4 RAM.
