The Comprehensive Guide to Buying Computer Memory

Understanding the Basics of Computer Memory

The world of computer memory can seem like a dense forest to tread through, especially for those new to the realm of computing. But fear not, for this ultimate guide will help you navigate through all the intricacies of buying computer memory, whether for personal or professional use; a desktop or a laptop.

The Difference between RAM and Storage

Before diving into the buying aspects, it’s crucial to understand two terminologies often used interchangeably – RAM and Storage. Both are part of a computer’s memory, but perform different functions. RAM, or Random Access Memory, is a temporary storage that your computer uses to run applications and data currently in use. On the other hand, storage is the computer’s long-term memory that stores your data permanently.

Types of Computer Memory

When you’re out to buy computer memory, it helps to know the types available in the market. Here are some of the most common ones:


One of the popular choices in today’s memory market is DDR4. DDR4 RAM stands for Double Data Rate Fourth Generation Random Access Memory. It’s faster and consumes less power than its predecessor, DDR3. If you’re looking for a balance between performance and cost, DDR4 is a safe bet.


An older model but still in use is the DDR3 RAM. If you have a legacy system and want to squeeze a few more years out of it without spending much, DDR3 might be the way to go.

Solid State Drives (SSD)

SSDs are a type of storage memory, increasingly replacing hard drives. With no moving parts, an SSD is more durable and quicker, making it an excellent choice if your work involves heavy data reading and writing tasks.

Factors to Consider when Buying Computer Memory

Understanding how to buy computer memory involves more than its type. Here are some factors to bear in mind:

Size of the Memory

The amount of memory you need is predominantly dictated by what you plan to do with your computer. Generally, the rule of thumb is, the more memory, the better. For heavy users, such as gamers and professionals running high-end software, 16GB or more is recommended. For casual users, a 4GB RAM can suffice.

Memory Speed

Memory speed, or clock speed, can impact how fast data is transferred. While it may not dramatically boost performance, it does matter when there’s a need for speed, such as gaming or video editing.


Before buying, ensure your computer’s motherboard can support the memory type and size. You can find compatibility data in the motherboard’s manual or the manufacturer’s website.

Value for Money

Expensive isn’t always better. You need to find a balance between your computing needs and budget.

Where to Buy Computer Memory

There are several reliable places to buy computer memory. Some of the best online platforms include Amazon, Best Buy, and Newegg. Ensure you buy from a reputable seller to avoid counterfeit products.

Concluding Thoughts

The world of computer memory can be intricate but armed with the right knowledge, buying computer memory can be a walk in the park. Making an informed decision can ensure you get the most out of your purchase.

Whether you are a high-end desktop user, gamer, or a casual PC user, knowing what suits your tasks can extend the life span of your computer, enhance its speed, and make your computing experience as smooth as possible. That’s the power of understanding how to buy computer memory.
