Best Computer Memory: The Main Criteria That Influence The Choice

It is necessary to choose the right configuration of the main components that affect the device’s performance and cost to ensure that a computer memory fully meets the tasks at hand. Even the highest processor will only be able to work at total capacity if the amount and type of RAM are combined with its architecture.

While most operating systems and applications recently recommended no more than 512 to 2048 MB of RAM, today, even entry-level systems recommend at least 4GB of memory. Therefore, many users planning to buy or upgrade their computer system always need help deciding how to choose RAM for their computer and laptop. To make the selection of RAM more comfortable, let’s look at the main criteria that influence the choice of computer memory type and capacity.

The Optimal Amount

As many users believe, “there is no such thing as too much computer memory,” and the larger the amount of memory, the more responsive the computer system will be, and the fewer freezes of resource-intensive programs will occur. It’s hard to argue with this statement, but there are some “buts” you should pay attention to when it comes to RAM size.

First, these are the motherboard’s capabilities, which can be found in its description. Another limitation in buying the maximum number of modules is its high price. In addition, you need to consider that as the amount of memory increases, the power consumption from the power supply increases, and there must be a sufficient power reserve.

Therefore, it is necessary to combine the desired with the type of tasks to be solved (office or home computer, gaming or graphics system, or a laptop).

Types of Modules

Despite a wide range of prices and a large number of manufacturers, memory modules are available in only two types:

  • DIMM (Dual In-line Memory Module)
  • SO-DIMM (Small Outline Dual In-line Memory Module)

The first type is most often used to complete desktop computer systems. SO-DIMM modules have more compact dimensions and are used in laptops (netbooks) and in some desktop systems (nettops and ultraportables).

Modern Standards

If you’re buying a new laptop or computer memory or building a home system from scratch, paying attention to DDR4 memory modules is best. Today, memory of this standard has the highest peak data transfer rate. At the same time, the supply voltage of DDR4 memory is 1.2 V (for the previous DDR3 standard, this figure was 1.5/1.65 V). As a result, the modules have become more economical in terms of power consumption (by 20-30%). Also, DDR4 modules allow for the installation of larger memory chips (theoretically, the maximum capacity of the module can reach up to 128 GB).

DDR3 modules have a more modest bandwidth (compared to DDR4 memory) and are mainly used to upgrade previous-generation systems (if you have a sufficiently robust motherboard and a processor that supports modules of this standard). DDR4 and DDR3 modules are hard to distinguish from each other, but their differences are significant: DDR4 memory has 288 pins, while DDR3 has 240. The modules are not interchangeable, and to prevent mistaken connections of other standards, they also differ in the location of the mounting slots.

Conclusion

Selecting the best RAM for your computer involves considering several crucial factors to ensure optimal performance and compatibility. The right amount of RAM depends on the tasks at hand, balancing performance needs with budget constraints and hardware limitations such as motherboard capabilities and power supply capacity.

Understanding the types of modules, whether DIMM or SO-DIMM, and keeping up with modern standards like DDR4 for new systems or DDR3 for upgrades is essential for maximizing efficiency and future-proofing your investment. You can confidently choose the perfect RAM configuration to enhance your computing experience by carefully evaluating these criteria.
