How much RAM is good for a Gaming PC?

If you want to build a gaming computer, you will want to consider the amount of RAM you will need.

If you plan to play games with a resolution of 1080p, you probably need 8 GB of RAM. But if you plan to play games in 4K resolution, you will need 16 GB of RAM.

There is a lot of confusion about the amount of RAM needed for a gaming PC. Some people think that 8 GB of RAM is enough while others think that 16 GB of RAM is required. The truth is that there is not a certain amount of RAM you need. It depends on what kind of game you are playing and how high you want to run the game settings.

In this article I will explain exactly how much RAM you need to buy for your gaming pc.

What is the right amount of RAM to play PC games?

The first thing we need to do is figure out what type of graphics card you want to use to determine how many GB of memory is needed. There are two types of cards: GDDR5 or DDR3. Both offer different speeds, but they also cost differently. Let’s look at both options so you can decide which one works best for you.

DDR3 vs GDDR5 graphics card

A graphic processing unit is responsible for reproducing 3-dimensional images from 2-dimensional images. This means that it takes all the information about an image and turns it into pixels. These pixels make up the last image you see when watching a movie or playing a game.

When building a new system, you may not know if you want to go with DDR3 or GDDR5. You may even ask yourself, why would anyone choose DDR3 over GDDR5? Well, here’s why …

You get more for your money with DDR3 than you do with GDDR5. With DDR3 you pay less money per. Gigabyte of memory compared to GDDR5. Let us e.g. Say you wanted to buy 1 TB of memory worth. A single stick DDR3 costs $ 100, while a single stick GDDR5 costs $ 200. So by buying only 1 TB DDR3 instead of 1 TB GDDR5, you save $ 300! It’s pretty amazing.

You do not have to use all the memories you have purchased. In fact, most systems use only half of their total capacity. However, if you have extra memory available, you can increase performance without spending too much money.

Factors besides RAM that affect gaming performance

Now that we’ve covered the basics of RAM, let’s talk about some other factors that affect gaming performance. Here are three things to keep in mind before buying components for your next gaming realm.

1. CPU speed –

CPU speed has a huge impact on overall performance. Faster CPUs allow you to load programs faster and perform tasks faster. They also help reduce delay time between actions. As such, it is important to choose a fast processor because it helps to enhance the gaming experience. If your cpu is not compatible with other parts, it will hinder your system performance.

Motherboard size –

Motherboards are available in different sizes. Smaller motherboards tend to fit better in smaller cases. Larger motherboards usually require larger cases. That is why size is important. Make sure you choose something that fits snugly inside your bag. See also our motherboard size guide to learn more.

3. Video card type –

We have already mentioned that there are two main types of graphics cards: DDR3 and GDDR5. Each offers its own benefits. If you want to build a budget-friendly computer, then DDR3 is probably what you should consider. But if you plan to upgrade later along the way, you will definitely benefit from going with GDDR5.

4. Case Style & Cooling System –

There are several styles of cases. Some are built specifically for overclocking, while others are not. The style you choose depends largely on personal preferences. It also depends on what kind of cooling system you intend to install.

5. Power supply quality –

The quality of power supplies can have a big impact on how well your system works. Cheap PSUs often produce large amounts of heat, which can damage your hardware. On top of this, they typically lack sufficient wattage power. To avoid these problems, look for a PSU that meets at least 80 Plus Bronze standards.

Single module vs multiple modules

If you were wondering when you would see more modules installed in a slot, now is as good a time as ever. Today, many manufacturers offer dual-channel kits where each module comes pre-installed. This means that you do not have to buy more slots. Instead, all you have to do is plug them in.

Cables with two channels

A dual-channel kit consists of 2 identical sticks of RAM. These are soldered together so that both channels work simultaneously. Dual-channel cables provide greater bandwidth than single-connector configurations. For example, 8GB of DDR3 will run at 1333MHz instead of 1066MHz. It may be a good idea to use dual-channel kits if you plan to run games like Battlefield 4 or Call Of Duty Black Ops 3.

Multi-Channel Kit

Multi-channel kits consist of different sizes of RAM chips. Typically, multi-channel sets include 1 × 8 GB, 1 × 16 GB and / or 1 × 32 GB. In addition, most multi-channel kits have ECC memory. This allows you to use lower latency speeds without compromising data integrity.

Number of sticks

RAM sticks are available in different numbers. Most systems today come with four sticks of RAM. However, some computers only support three sticks. Whether you get fewer or more sticks, be sure to buy compatible RAM. Otherwise, you risk damaging your motherboard by installing incompatible RAM.

Summarizes the role of RAM in gaming PCs

As we have seen above, RAM plays an important role in gaming PCs. Without it, the performance would suffer a lot. That said, not all players need 16 GB of RAM. As long as you do not exceed 32 GB, you should not encounter any problems. Just keep in mind that bigger is not always better.


In conclusion, RAM has become increasingly popular in recent years. With the right amount of RAM, you can enjoy smooth gameplay even under heavy load conditions. We hope our guide helped answer your questions about RAM!
