What is MHz in RAM? The processing frequency of a computer’s processor is measured in MHz, which stands for megahertz. This measurement tells you how many instructions per second the processor can execute. A higher number means that the processor will be able to process instructions faster than a slower one.

RAM is one of the most important components. It is short for Random Access Memory, and it is a device that stores computer data. The more RAM a computer has, the more data it can store and process at any given time.

What Is MHz In Ram?

So, MHz is a measurement unit or memory performance frequency. The way we measure frequency for any object movement per second, computer memory operations are calculated similarly.

And this is the mega Hertz written as MHz. It’s another standard unit of Hz, also known as s-1. It simply indicates the cycle operation of instruction memory can complete per second and is calculated in the mega unit.

What Is RAM Speed?

So, the same answer goes for this as we did for the MHz. Ram speed is the frequency processing speed of its operations in a second.

There are several options when it comes to choosing RAM speed. The speed ranges from 1300MHz, 1600MHz, 2130MHz, 3200MHz, and up to 4266MHz. For example, 8G DDR4-2400 RAM runs at a 2400MHz frequency speed.

DDR5 is the latest version of DRAM used almost worldwide. DDR is an abbreviation for “Double Data Rate”, and the stock ddr4 ram speed mhz is generally 2400MHz or 2133MHz.

Two DDR sticks with a combined capacity of at least 32GB, each with 3200MHz speed is ideal for a high-performance setup. You can go over this, but usually, this is the sweet spot for gaming and streaming.

The Difference Between RAM Frequency And CAS Latency

RAM frequency is a part of the speed, although many people confuse it for RAM speed. To measure RAM, you will have to calculate the number of cycles it can perform every second. For example, if a RAM performs 3.2 billion cycles every second, it is rated at 3200MHz.

The higher the number of cycles your RAM performs, the more data can be read and stored. DDR and RAM are usually correlated.

On the other hand, CAS is the delay between the time RAM receives and issues a command, and CAS is short for Column Access Strobe.

A series of numbers indicate the number of clock cycles your RAM needs to issue a command. Slower CAS timings with faster MHz RAM tend to be slower than fast CAS timings with slower MHz RAM.

Is Higher MHz Better?

Higher MHz RAM can make your setup operate faster. However, that is not the case in most scenarios. If you are force-feeding your CPU more data, it might not make your PC faster.

In most scenarios, you will not be able to tell the difference. Higher MHz might be better in technical terms but not in real life. How fast RAM performs depends on several other factors such as bandwidth, latency, DDR, number of channels, etc.

More RAM is better than faster RAM. Additionally, it would be unwise to go over the required speed of your CPU and motherboard.

Does MHz Matter in RAM Compatibility?

Of course, it does.

A higher RAM does not always benefit the overall system performance, but can it cause any harm? Reaching the insane high MHz number will overclock high-frequency RAMs.

Despite this not being a usual scenario, going for a higher RAM and risking your PC’s system is not worth it. It can make your system act unstable and cause crashes or freezes. Moreover, you will not even see a significant difference using a higher MHz RAM.

Does A Higher MHz increase FPS?

If higher MHz RAM will increase, FPS depends on the amount of RAM. In some cases, it can. It is possible to increase FPS by adding more RAM to your system, but every game needs a different amount of memory for it to run. The amount can differ from game to game.

Is It Necessary To Get The Fastest RAM Speed For Gaming?

Generally speaking, gamers don’t need to purchase the fastest RAM. However, it is also dependent on the CPU you own. RAM kits that have tighter timings might improve FPS in certain games.

However, this improvement is still not as satisfactory as you will get by upgrading your GPU. For Intel and AMD, 3200MHz or 3600MHz will work well.

A higher speed, such as 4000MHz RAM, can increase your overall cost, especially a RAM kit with tight timings.

Is RAM MHz Important In Gaming?

RAM frequently does not significantly impact a system’s overall performance. So you might be questioning whether RAM MHz impacts gaming.

A graphics card is generally one of the essential parts of a gaming system. RAM does not necessarily impact gaming.

It would be best to spend on an advanced graphics card and processor instead of opting for faster RAM. 3000-3200MHz RAM is generally the sweet spot for gaming PCs.

Is 32GB Too Much For Gaming?

Mostly, yes 32GB is overkill. 32GB is not necessary unless you need it for future-proofing. Gamers can use 16GB for a good gaming setup. Even 8GB is enough for gamers, and the gaming experience will still be just fine.

Is 2133MHz And 1600MHz RAM Good?

For most games, 2133MHz and 1600MHz RAM is good. As long as the other components of your PC live up to the speed, 1600MHz RAM will not be an issue. Other devices heavily impact devices that use DDR3 1600MHz RAM on your PC.

As for 2133MHz RAM, it would work perfectly fine for gaming. When most people used the DDR3, faster RAM was costly. Therefore, people generally used 1600MHz unless they had particular needs.

Frequently Asked Questions (FAQs)

Does MHz matter in RAM?

MHz makes a difference in every type of RAM, despite what generation RAM you have. MHz is vital in RAM as it speeds up the clock cycles and the rate at which the data transfers every second. MHz is essential in every version and size of RAM.

Is 3000 MHz RAM good?

While building a new AMD system, 3000MHz would be the minimum RAM speed requirement. You can use a higher RAM if it is within your budget, but chances are you might not notice a big difference between 3000MHz and a higher speed. It is best to stay between 3000MHz and 32000MHz for gaming.

What is a good MHz for RAM?

The MHz needed for specific RAMs depends on the processors, GPU, and CPU you are using. A 16GB or 32GB at 3200MHz RAM would be ideal for gamers who use Intel processors. As for AMD CPUs, the same GB with 3600MHz RAM would work perfectly.


We hope you have a proper idea of what is MHz in RAM. It is not as complicated as it seems.

You should always purchase the RAM size required by your PC components, such as motherboard and CPU. A higher MHz RAM is not guaranteed to improve your system’s performance. You will barely notice the difference by switching to a higher RAM speed.

Is Roccat a good brand- What Experts Say?

If you are a hard-core gamer, RAM MHz can be a matter of concern for you, and 3200MHz should work perfectly fine for you.
