How do I choose the computer RAM

The EMAG online store sells a wide range of products, including RAM. If we access the section with RAM, we will see an offer with different features. The large number of products can sometimes put you in the «fog», in particular on the user for beginners, who wants to choose a computer RAM.

We choose the RAM memory by type and slot

The first thing you need to do by choosing RAM is the type of memory. In the modern computer there are four types of memories:

• DDR – The first version of the GDR can now be rarely found;
• DDR2 – The second generation DDR is found on old computers;
• DDR3 – The third generation DDR, the most common version right now;
• DDR4 – The most modern DDR version is found only on new computers;

To find out which of these types of memory is used on your computer, run the CPU-Z program and open the «Memory» tab. Here the type of memory, quantity and frequency will be specified.

If you want to find out more information on each installed RAM plate, access the «SPD» tab.

In addition to the type of memory (DDR, DDR2, DDR3 or DDR4) it is necessary to consider that different connectors are used for the desktop and laptops. Dimm connectors are used in Dimm connectors and so-dimm laptops. SO-Dimm can also be used in mini types of desktop computer PCs.

To be sure that the chosen memory will enter the RAM slot on the motherboard, must correspond not only to the type of memory, but also to the connector.

We choose the desired frequency

After deciding with the type and connector of the RAM, you will have to decide with the memory frequency. There are some important points here:

• Memory frequency should be supported by the motherboard. Usually there are no problems, because modern basic plates support different RAM frequencies. However, it is better to check. To do it in place in the search engine, the name of the motherboard and access the website of its manufacturer. On the site you will find the specifications and frequency supported by the motherboard.
• In addition, the frequency of memory must be supported by the processor. Check the same. Enter the name of the processor in the search engine and consult the characteristics on the manufacturer’s official website.
• Then discover the maximum frequency of memory, with which the motherboard and the processor will work. This is frequent, that you can use.

At the same time, I must specify that:

• You don’t necessarily have to buy RAM with the maximum frequency accepted. To save you can choose the memory with a lower frequency. It is important that this frequency is supported by the motherboard and processor.
• If the type of memory corresponds, you can install the RAM with a higher frequency. Except that it will work at the maximum frequency supported by the motherboard and the processor.
• You can install RAM with different frequencies, only it will work at the lowest frequency of the RAM. Even if I don’t recommend it.

Check the maximum amount of RAM memory and the availability of slot on the motherboard

Another important moment, which must be taken into consideration by choosing the RAM, is the maximum amount supported by the motherboard and the processor. On the site of the manufacturer of the motherboard and the processor (even where the frequency occurred) check the maximum quantity of RAM. This amount cannot be overcome.

In addition, check the availability of free slots on the motherboard. To make him remove the side cover and check the motherboard. It is important not to forget before disconnecting the computer.

Final internship

It would be good to install the same branch plates. In this way you will be exempt from compatibility problems, which although very rarely, but appear. If you have the opportunity, it is better to install the entire kit.

If you do not have the opportunity to install the entire kit, choose memory with the characteristics close to those installed on the computer (compare the frequency, quantity).

Conclusion

Choosing the right RAM can be a confusing process, especially for beginners confronted with the wide variety of products available in online stores like EMAG. With so many models, capacities, and specifications, it is easy to feel overwhelmed by technical terms and compatibility concerns. However, by understanding a few fundamental principles, users can make an informed and confident decision that enhances their computer’s performance.

The most important factor when selecting RAM is its type and slot compatibility. Modern computers generally use one of four main types of memory: DDR, DDR2, DDR3, or DDR4 (and now DDR5 in newer systems). Each generation offers improvements in speed, energy efficiency, and performance, but they are not interchangeable — meaning you must choose the one that matches your motherboard’s specifications. Checking your computer’s manual or using tools like CPU-Z can quickly clarify which memory type your system supports.

In addition to type, other characteristics such as capacity, frequency, and latency also influence performance. For example, more RAM capacity allows for smoother multitasking and better handling of demanding applications, while higher frequency improves data transfer speed. However, it’s also essential to balance these features with your system’s limitations to avoid spending on unnecessary performance that your hardware cannot utilize.

Ultimately, buying RAM should not be a random decision but a strategic investment in your computer’s speed and reliability. By understanding your needs — whether for gaming, video editing, or everyday use — and verifying compatibility before purchase, you can ensure that your system runs efficiently. EMAG’s wide selection provides an excellent starting point, offering options for both casual users and professionals who demand top-tier performance. With the right knowledge, choosing RAM becomes less of a challenge and more of an opportunity to optimize your computer’s potential.
