Understanding the differences between the different RAM types is essential when you want to upgrade a computer or build a new one. RAM is like the short-term memory of a computer. Just like our brains need to access information quickly to perform tasks efficiently, the CPU (Central Processing Unit) of a computer needs fast access to data in order to execute instructions effectively. When you open a program or a file, it gets loaded into RAM, allowing the CPU to quickly access and manipulate the data.
RAM is different from the long-term storage devices like hard drives or solid-state drives (SSDs). While these storage devices store data permanently even when the computer is turned off, this Memory is volatile and loses its data when the power is cut off. This is why it is called “random access” memory, as the CPU can access any piece of data stored in this Memory directly, without having to search through the entire storage device.
When a computer runs out of RAM, it starts using a portion of the hard drive or SSD as virtual memory, which is much slower than accessing data directly from RAM. This can lead to a noticeable decrease in performance, as the CPU has to wait longer for data to be retrieved from the slower storage device. This is why having enough Memory is crucial for smooth multitasking and running resource-intensive applications like video editing software or video games.
Upgrading the RAM in a computer is often one of the most cost-effective ways to improve its performance.
Types of RAM
There are several types available in the market, each with its own unique characteristics and specifications. Let’s take a closer look at the most common types:
DDR5
DDR5 RAM, also known as Double Data Rate 5 Random Access Memory, is the latest generation of RAM technology. It is an improvement over its predecessor, DDR4, offering faster speeds and increased bandwidth.
DDR5 RAM offers faster data transfer rates, allowing for quicker access to stored information. This is especially beneficial for tasks that require high-performance computing, such as gaming, video editing, and 3D rendering.

DDR4 has significantly improved performance compared to older RAM types. It is designed to operate at higher clock speeds, allowing for faster data access and transfer. This makes DDR4 ideal for demanding applications such as gaming, video editing, and graphic design.
In addition to its speed and performance, DDR4 also offers increased memory capacity. DDR4 modules can have higher densities, allowing for larger amounts of Memory to be installed in a single system. This is particularly beneficial for users who require a large amount of memory for multitasking or running memory-intensive applications.
Furthermore, DDR4 is designed to be more energy-efficient. It operates at lower voltages compared to DDR3, resulting in reduced power consumption. This not only helps to lower energy costs but also contributes to a greener and more sustainable computing environment.
DDR3
DDR3, or Double Data Rate 3, was the standard RAM type before DDR4 was introduced. It is still widely used in older computer systems and laptops. DDR3 modules offer decent performance and are compatible with motherboards that support DDR3 technology. However, they have slower data transfer rates and higher power consumption compared to DDR4.
DDR3 is a reliable and cost-effective option for users who don’t require the latest and greatest performance. It is suitable for everyday computing tasks such as web browsing, document editing, and multimedia playback. While DDR3 may not offer the same level of performance as DDR4, it can still provide a smooth and responsive user experience.
One advantage of DDR3 is its compatibility with older systems. Many older motherboards and processors are only compatible with DDR3, making it the only viable option for upgrading the memory in these systems. Additionally, DDR3 tends to be more affordable than DDR4 , making it a budget-friendly choice for users on a tight budget.
DDR2
DDR2, or Double Data Rate 2, is an older RAM type that is rarely used in modern computer systems. It has slower data transfer rates and lower memory capacity compared to DDR3, DDR4 and DDR5. DDR2 modules are compatible with motherboards that support DDR2 technology.
DDR2 was commonly used in computers from the mid-2000s to early 2010s. It offered improved performance compared to its predecessor, DDR, but was soon replaced by DDR3 due to its limitations. While DDR2 may still be found in older systems, it is not recommended for use in modern computers due to its outdated technology and limited compatibility.
DDR
DDR, or Double Data Rate, is an even older RAM type that is now considered obsolete. It has slower data transfer rates and lower memory capacity compared to DDR2, DDR3, DDR4, and DDR5. DDR modules are compatible with motherboards that support DDR technology.
DDR was widely used in computers during the late 1990s and early 2000s. It offered significant improvements in performance compared to its predecessor, SDR (Single Data Rate). However, DDR has long been surpassed by newer and faster RAM technologies, such as DDR2, DDR3, DDR4, and DDR5.
Due to its outdated technology and limited compatibility, DDR is no longer recommended for use in modern computer systems. Users looking to upgrade their RAM should consider DDR2, DDR3, DDR4, or DDR5 options, depending on the compatibility of their motherboard and the performance requirements of their applications.
As we can see in the previous image, the different types of RAM in appearance can be very similar, but in reality there are fundamental physical differences that prevent you from making a mistake and, for example, trying to install a DDR4 memory module on a motherboard. which only supports DDR5 memory. The different standards have a small gap in the connection area of the memory module, it is designed to avoid two specific scenarios:
- Avoid installing a RAM module in an unsupported socket.
- Install the memory module in the correct position.
RAM Brands and Manufacturers
There are multiple memory companies on the market, but only a few true memory manufacturing companies. When researching different memory brands, you may run across companies that claim to be memory manufacturers, when they’re really just module assemblers. How these companies work is that they purchase pre-manufactured parts (such as DRAM chips and printed circuit board) from true memory manufacturers, and then assemble these components to “manufacture” a module with their label on it.
True memory manufacturing involves a much higher level of technical expertise and quality control, and involves everything from selecting choice silicone to functional module testing. Memory manufacturers design, produce, and test components and modules at all stages of production. Memory modules consist of two pieces: DRAM semiconductor chips that store data, and printed circuit board (PCB), which connects the memory chips to the rest of the computer.
Technically, there are only a handful of semiconductor manufacturers with the capability to produce DRAM chips, and they are Micron (Crucial), Samsung, and Hynix. The companies that actually sell RAM take these modules and place them in their own PCB sticks.
That being said, there are several well-known brands that sell RAM. Each has its own distinct look, performance, price and compatibility with different types of motherboards. Here are all those major brands.
RAM Samsung
Samsung is one of the few companies that actually produce RAM, but that doesn’t make it the go-to brand for RAM. The company hasn’t really broken into the performance RAM market, and you would be hard-pressed to find a stick available. You could certainly find some laptop RAM, but that won’t be compatible with your desktop motherboard.
If you’re looking to upgrade an old laptop, then Samsung is a great option. The desktop sticks they have available are also good choices for server solutions.
RAM Micron
While they are good solutions for basic desktops or server solutions, this isn’t what you would want to put in a gaming PC. Micron memory doesn’t support XMP profiles (XMP is short for Extreme Memory Profiles. Essentially, RAM that supports that profiles can easily have the speed adjusted by switching to a different profile in the BIOS, which makes overclocking fast and simple), and it also lacks a lot of the heat spreaders found in gaming RAM products. Spreading heat is especially important in a gaming PC since most of the components will be pushed to their limits, creating a lot of heat.
Unless you’re upgrading a laptop or building some type of server, you will be better served by a different brand than Micron.
RAM Adata
ADATA has been around for a long time and is a staple budget brand for several PC components. The company offers regular RAM sticks that are great for standard desktops or servers, but the company also has an XPG line of gaming memory. XPG has the angular design for the heat spreader you would expect for a gaming product.
There are some compatibility issues with certain motherboards. Make sure you do your research to see if this product works with your board before buying.
RAM Crucial
Crucial is another budget brand for PC components, and the company also has RAM sticks available for sale. Crucial is owned by Micron, so it gets the benefit of having rigorous testing for and a direct line to its RAM modules. It’s also pretty affordable. There have also been reports of compatibility issues with certain MSI boards.

There is, of course, XMP support, so you can overclock these sticks and make your PC flashy in the process. The biggest drawback to Silicon Power is the out-of-box performance. Users have reported clock speeds that are lower than advertised, and they had to adjust settings in the BIOS to get those reported speeds. The good news is the RAM does perform as advertised, you just have to get it there yourself, which is less than ideal.
Patriot
Patriot makes some of the best RAM products around, and you can often find them in roundup lists when you search for the best RAM. Produced in the U.S., it also has great customer service support.
Patriot a significantly pricier option, but you’re getting a premium product at that price. You’re getting snappy speeds, excellent XMP performance, and RGB goodness in the package.
However, users have reported some issues with Patriot products. While customer service is great, customers have had their products arrive mislabeled, and sometimes they don’t work at all. Customer service is quick to replace these, but it does make it a hassle and a bit of an unnecessary annoyance to deal with.
Corsair
Corsair is one of the top names in PC accessories, and it makes a lot of peripherals including keyboards and gaming mice. Corsair is also the undisputed leader in gaming RAM. The Vengence line of RAM offers best-in-class performance, and Corsair undoubtedly has the best-looking products on the market.
Since Corsair is so popular it’s widely compatible with basically every motherboard brand. The components also include XMP 3.0 support with custom profiles also makes for a simple and powerful overlocking experience. Corsair provides the best RAM brand on the market.
Choosing the Right RAM
When it comes to choosing the right RAM for your computer, there are a few factors to consider:
1. Compatibility
First and foremost, ensure that the RAM you choose is compatible with your computer motherboard. Check the motherboard’s specifications to determine the type and maximum capacity of Memory it supports. Installing incompatible Memory can lead to system instability and performance issues.
2. Capacity
The capacity of RAM determines how much data your computer can store and access at any given time. If you use resource-intensive applications or multitask heavily, consider opting for higher capacity Memory modules. However, keep in mind that the operating system and software you use also have their own memory requirements.
3. Speed
The speed of RAM, measured in megahertz (MHz), determines how quickly data can be transferred to and from the memory. Higher Memory speed modules offer better performance, especially when running memory-intensive applications or gaming. However, the benefits of higher speed may not be noticeable in everyday tasks especially those that do not require too much memory or speed.
4. Budget
Lastly, consider your budget when choosing RAM. Higher capacity and faster Memory speed modules tend to be more expensive. Evaluate your needs and prioritize accordingly.
Additionally, it is worth mentioning that the type of RAM you choose can also affect its performance. There are different types of Memory available in the market, such as DDR3, DDR4, and DDR5. DDR4 is currently the most common and widely used type of RAM. It offers faster speeds and lower power consumption compared to DDR3.
Another factor to consider is the number of RAM slots available on your motherboard. Some motherboards have only two slots, while others may have four or more. If you have limited slots, it may be more cost-effective to purchase higher capacity RAM modules to maximize your available memory. On the other hand, if you have more slots, you can opt for lower capacity modules and add more RAM in the future if needed. Lastly, it is important to note that installing Memory is relatively easy and can be done by most computer users.
