2 Ways to Know RAM Speed ​​In Windows

2 ways to know ram speed in windows.

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

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

RAM is very important for multitasking because it is the working memory of the computer and as a place to store ongoing tasks 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 are going to give you an overview of how to find out the RAM speed of your Windows computer.

1. Use Windows Task Manager

The first method involves the Windows Task Manager in Windows 8, Windows 8.1, Windows 10, and Windows 11. Older Task Managers like those in Windows 7 and older operating systems don't show this information, so if you have an older version of Windows old, please refer to other methods in this post.

The first thing you need to do is access the Windows Task Manager. You can access it by right-clicking on the Windows taskbar and then clicking the Task Manager option. Alternatively, simply press Ctrl + Shift + Esc keys which will boot the Task Manager.

If this is your first time opening Task Manager, you may want to click View more to expand an oversimplified version of Task Manager. Then, click on the Performance tab, where you'll see a number of metrics on CPU, RAM, and GPU usage.

Click on Memory to see information about your RAM. Below the graph itself, you will be able to 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 admin RAM is running at 2400MHz. Most modern computers, run DDR4 RAM between 2133MHz to 3600MHz, even with some RAM kits it can exceed 4000MHz. DDR3 RAM, on the other hand, only goes up to 1866MHz.

2. Use CPU-Z

CPU-Z is a utility that allows users to view several pieces of data about their computer, including information about the computer's CPU and 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 unreliable for whatever reason.

First, go to the CPUID download page. You can download any version you want, although we recommend using one of the latest versions if you have newer hardware on your system. The latest version of CPU-Z has added support for DDR5 memory and Intel 12th generation Alder Lake CPUs.

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

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

Why Knowing RAM Speed ​​Is Important

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

One common error that many PC makers end up making is not setting up the XMP profile properly in the BIOS after completing their PC setup. This will result in your computer's RAM running at the default clock speed of 2133MHz instead of the advertised speed. This can result in a performance penalty.

Another reason might be to check if everything is working fine after the RAM upgrade. If you're on a laptop, installing an aftermarket kit that runs at 2666MHz while the computer's memory runs at 2400MHz will result in the RAM being downgraded to the slower speed of the two.

Even replacing it completely may still not make it run at the advertised speed, as the laptop may not be capable of running RAM at speeds higher than 2400MHz. You should check this before, during, and after, upgrade, and troubleshoot accordingly.

Why is RAM Speed ​​Important?

RAM speed, or data rate, determines how fast memory can transfer data to and from your CPU. At DDR4, or Double Data Rate 4, we typically see RAM running at speeds between 2133MHz and 3600MHz.

When you buy a new computer, or just buy memory, you will 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 data rate times eight. For example, PC4-25600 memory is rated at 3200MHz, while PC4-28800 memory is rated at 3600MHz.

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

In most applications, having more RAM is also better than faster RAM. However, if you're playing games, a faster RAM might help you get a bit more performance and a few frames per second.

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

And one important thing that you should remember is that if you are looking for an upgrade, you are better off buying more RAM than replacing your existing RAM with much faster RAM.


So that's how to find out RAM speed. People often overlook RAM speed, especially considering that getting more RAM is better than getting faster RAM. However, if you need to check that everything is working as it should, now you know how to do it.
