How to Choose the Right RAM for Your Computer

Your Guide to buying the best RAM


This RAM buying guide is designed to help you select the right RAM for your computer. We will provide information on the different types of RAM, their performance, and other factors to consider. We will also provide information on how to properly install RAM and the tools needed. Ultimately, this guide will provide you with the knowledge and tools needed to make an informed purchase.

Key features

  1. Type - Computer RAM typically comes in the form of DDR3 or DDR4. DDR3 is an older, slower technology while DDR4 is faster and more efficient.
  2. Size - Computer RAM sizes range from 4GB to 64GB depending on the type of computer you’re using. Generally, more RAM will improve the performance of your computer.
  3. Speed - Speed is determined by the type of RAM you are using, with DDR3 RAM having lower speeds than DDR4 RAM. Generally, the faster the RAM, the more expensive it is.
  4. Compatibility - Make sure your RAM is compatible with your computer's motherboard, CPU, and operating system. Check the manual or manufacturer's website for compatibility information.
  5. Brand - Different RAM manufacturers can offer different levels of quality and reliability. Make sure to research the brand before purchasing.
  6. Price - Consider the cost of RAM when buying. Compare different brands and consider how much RAM you need, as this will affect the price.

Important considerations


  • Cost - RAM can be relatively inexpensive compared to other types of computer memory.
  • Speed - RAM is much faster than other types of memory, meaning that your computer will be able to process more information faster.
  • Capacity - RAM comes in a variety of sizes, so you can choose one that meets your needs.
  • Compatibility - RAM is compatible with most computer systems, so you don't have to worry about compatibility when upgrading.
  • Upgradeability - RAM is relatively easy to upgrade, so you can add more RAM as your needs change.
  • Reliability - RAM is a reliable form of memory, so you can count on it to work properly.


  • Cost: RAM can be expensive and buying more RAM increases the cost of a system.
  • Compatibility: RAM must be compatible with the motherboard and processor in order to work properly.
  • Overclocking: Overclocking RAM can damage hardware if not done correctly.
  • Frequency: Different RAM sticks may have different frequencies, making it difficult to find compatible RAM sticks.
  • Latency: RAM latency can drastically affect system performance, so it is important to choose RAM with low latency.

Best alternatives

Common questions

  1. What type of RAM should I buy?
    • When selecting RAM, it is important to choose a type that is compatible with your motherboard, as well as the type of processor in your computer. Common types of RAM include DDR3 and DDR4, with DDR4 being the newer and faster RAM option.
  2. How much RAM do I need?
    • How much RAM you need depends on the type of applications you use and the number of programs you typically run at one time. For basic tasks, such as web browsing, emailing, and word processing, 4 GB is usually sufficient. Gaming and video editing require 8 GB or more.
  3. Do I need to buy RAM in pairs?
    • Most computers come with two RAM slots, and these slots usually have to be filled in pairs. This means, in order to get the most out of your RAM, it is best to buy two RAM sticks of the same size and speed.
  4. What RAM speed should I buy?
    • The speed of RAM is usually measured in Megahertz (MHz) and typically ranges from 800 MHz to over 4,000 MHz. Higher-speed RAM is usually more expensive, but will provide faster access to data stored in RAM. If speed is not a priority, a lower-speed RAM option may be more suitable.


In the early days of RAM, Intel first released the world's first 1 kilobit DRAM chip in 1971. It was the size of a quarter and had the equivalent memory of 256 bytes, enough to store a single sentence. The chip became known as the "tear-drop" for its distinctive shape. It was a breakthrough in memory design and started a revolution in the storage industry. Today, RAM can hold billions of bytes of data and is an integral component of any computer system.
