Understanding RAM: All You Need to Know Before You Buy Computer Memory

What is Computer Memory?

Imagine you’re a world-class chef in a high-end restaurant. Your brain is the computer, and your hands are the CPU, executing all actions. But what about the counter space where you temporarily place all the ingredients you’re using? That’s the computer memory, or more specifically, the RAM. When you’re looking to buy computer memory, there are a couple of things you must keep in mind. In this post, we will delve into many aspects of computer memory and how wisely you should purchase your computer memory depending on your requirements.

RAM: The Computer’s Short-Term Memory

RAM, or Random Access Memory, is a type of computer memory that allows data to be read and written almost simultaneously, regardless of where the data is located. It acts as a temporary storage space for data that is being used actively. The more RAM your computer has, the more “counter space” there is for your programs to work on, and the smoother your computer operates.

Types of Computer Memory

Though RAM is one of the most well-known types of memory, there are others. There’s ROM (Read-Only Memory), which contains data that can only be read and not modified, and there’s also the hard drive, which stores data long term. However, for the purpose of this article, we’ll focus on RAM as it is the type of memory typically bought and upgraded by consumers.

Why is Computer Memory Crucial?

Memory and Performance

The amount of RAM your computer has can dramatically impact performance. Just like a chef with more counter space can cook more efficiently, a computer with more RAM can run more applications simultaneously and smoothly.

Memory and Multitasking

More RAM allows for effective multitasking. It can store data from multiple applications, letting you quickly switch between them without any significant performance drops.

RAM Specifications: What Do They Mean?

DDR Types

When you’re looking to buy computer memory, you’ll encounter terms like DDR3 or DDR4. These refer to the generation of RAM and its speed. Later generations are faster and more efficient but may not be compatible with all motherboards.

Memory Speed

The speed of the memory, that is measured in MHz, tells you how quickly the memory can transfer data. Faster is typically better, but the real-world performance difference may not always be significant.

Memory Size

RAM size, measured in GB, indicates how much data can be held in the memory at any given time. More GBs means your computer can handle more tasks at once.

Where to Buy Computer Memory?

Online Marketplaces

Many prefer to purchase computer memory from online marketplaces due to the wide variety, competitive pricing, and the convenience of home delivery. Websites like Direct Macro are popular online. 

How to Choose the Right Computer Memory


Not all memory is compatible with all computers. Before you buy, check your motherboard’s specifications to ensure the RAM you’re buying is compatible.

Requirements and Usage

Consider what you use your computer for. Light users might get by with 8GB, while heavy users and gamers might want 16GB, 32GB, or more.

Brand and Pricing

While brand isn’t everything, reputable brands tend to offer higher-quality, reliable products. Also, remember that the cheapest option isn’t always the best. Consider reviews and ratings available on Direct Macro’s website before making a decision.

Installing New Memory

Installing new RAM is generally a straightforward process, but it can vary depending on your computer. Always refer to your motherboard’s manual for installation instructions, or consider hiring a professional if you’re unsure.


What happens if I install more RAM than my computer can handle? 

If you install more RAM than your motherboard or operating system can support, the excess RAM will not be recognized and used.

Can I mix different brands or types of RAM? 

It’s usually best not to, as different brands and types can have different speeds and timings, which can cause instability.

Is more RAM or faster RAM a better choice? 

Both are important, but if you frequently multitask or use memory-intensive applications, having more RAM may be more beneficial.

Can I install RAM myself?

 Yes, installing RAM is usually a simple process. However, always consult your motherboard’s manual or a professional if you’re unsure.

Where can I buy computer memory? 

RAM can be bought online from various marketplaces like Direct Macro. .

In a nutshell

Understanding RAM and its importance can make a significant difference in your computer’s performance. Whether you’re a casual user or a diehard gamer, picking the right memory for your needs is crucial. Take into consideration the compatibility, your usage, and the reputation of the brand. Remember, a smooth-performing computer is often a result of a well-informed decision on memory.
