2 Ways to Know RAM Speed ​​in Windows

There are several reasons why it is important to know the RAM speed we have, but how do we know the RAM speed?

A computer is a device made up of many different components and they all work together to create a cohesive multifunctional system. But a very important component of a computer system is Random Access Memory, or RAM in short.

RAM is very important for multitasking, as it is the working memory of the computer and as a storage place for tasks in progress for quick access. The more RAM you have, the more tasks you can perform simultaneously.

But not everything is based on memory size. RAM speed is also an important factor to consider. Today, we’ll give you an overview of how to find out the RAM speed of your Windows computer.

How to know the RAM speed

1. Use Windows Task Manager

Use Windows Task Manager

The first method involves Windows Task Manager in Windows 8, Windows 8.1, Windows 10, and Windows 11. Older task managers, such as Windows 7 and older operating systems, do not display this information, so if you have an older version for old Windows, please see other methods in this post.

The first thing you need to do is go to Windows Task Manager. You can access it by right-clicking on the Windows taskbar and then clicking Task Manager. Or, just press the button Ctrl + Shift + Esc which will start the Task Manager.

If this is your first time opening the Task Manager, you may want to click See more to extend an oversimplified version of Task Manager. Then click the tab Performancewhere you will see a number of values ​​regarding CPU, RAM and GPU usage.

Click on Memory to view RAM information. Below the graph itself, you can see some information about your memory, such as the form factor, the slots used on the motherboard, how much RAM is reserved for the system, and the RAM speed.

In the example here, you can see that the administration RAM is running at 2400MHz. Most modern computers run DDR4 RAM between 2133MHz and 3600MHz, even with some RAM kits it can exceed 4000MHz. DDR3 RAM, on the other hand, only runs at 1866 MHz.

2. Use CPU-Z


CPU-Z is a utility that allows users to view more data about their computer, including CPU information and computer RAM. CPU-Z is a good choice if you have an older version of Windows or if the information displayed by the Task Manager seems unsafe for any reason.

First, open it halaman download windows CPUID. You can download any version you want, although we recommend that you use one of the latest versions if you have newer hardware on your system. The latest version of the CPU-Z has added support for DDR5 memory and 12th generation Intel Alder Lake processors.

Once downloaded, install the software (or open it if you downloaded the portable version), then open it. Then click the tab Memory.

To get the real speed of RAM, you just need to multiply that “single data rate” by two: 1197.7 x 2 gives us 2395.4 MHz, which is much closer to the 2400MHz reported that we have seen earlier.

Why it is important to know the RAM speed

There are several reasons why you might want to know the RAM speed. One is that after building a custom PC, you may want to check if the RAM is set up correctly or not.

A common mistake that many computer manufacturers end up making is not setting the XMP profile in the BIOS correctly after completing the computer setup. This will cause the computer’s RAM to run at the default clock speed of 2133 MHz instead of the displayed speed. This can lead to a performance penalty.

Another reason might be to check that everything is working properly after upgrading RAM. If you’re on a laptop, installing an aftermarket kit running at 2666MHz while your computer’s memory is running at 2400MHz will degrade your RAM to a slower speed of both.

Even a complete replacement may not make it run at the advertised speed, as the laptop may not be able to run RAM at speeds above 2400MHz. You should check this before, during and after, update and troubleshoot accordingly.

Why is RAM speed important?

RAM speed, or data rate, determines how fast data can be transferred to and from your processor. At DDR4 or Double Data Rate 4, we usually see RAM running at speeds between 2133MHz and 3600MHz.

When you buy a new computer or just buy memory, you’ll often see the memory speed listed on the spec sheet. For RAM running at 3200MHz, for example, you will see the RAM speed listed as “DDR4-3200”.

You may also see it listed as a “PC4” specification, which is the data rate eight times. For example, the PC4-25600 memory is rated at 3200MHz, while the PC4-28800 memory is rated at 3600MHz.

The easiest way to find out the RAM speed is “faster data rate, faster RAM”. But it is not very specific, as several factors can affect the performance of RAM. Like CAS latency, for example, it can increase as data rates increase, and this can have a negative impact on performance.

In most applications, having more RAM is also better than faster RAM. However, if you play, faster RAM can help you get a little more performance and a few frames per second.

Faster RAM can cost more than regular RAM, especially when you’re trying to keep your CAS latency low while continuing to increase your speed.

And one important thing to keep in mind is that if you’re looking for an upgrade, it’s better to buy more RAM than to replace your existing RAM with much faster RAM.

Here’s how to find out the RAM speed. People often overlook the speed of RAM, especially since getting more RAM is better than getting faster RAM. However, if you need to make sure everything is working properly, now you know how to do it.
