Discover our range of RAM

Upgrading your RAM (computer memory) is a great way to boost your system’s performance. Whether you're looking for laptop RAM or desktop RAM, adding more memory can help speed up everything from everyday tasks to intensive applications. 

More RAM gives you the freedom to run large programs and multiple applications at once without sacrificing performance. So, if your device is feeling sluggish, an upgrade to your PC memory could be just what it needs!

How much RAM do you need?

The amount of RAM you need depends on how you use your device. For general use like web browsing and office applications, 8GB of RAM is usually enough. But if you frequently run multiple programs at once, or do complex tasks like photo or video editing, 16GB RAM is a better fit. For gamers, content creators, and professionals working with large files or advanced software, 32GB or even 64GB will make sure your system performs smoothly without bottlenecks.
Choosing the right amount of RAM comes down to balancing performance and budget. You don’t need to go overboard if you don’t need it, but having extra memory can help keep your device future-proof for years to come.

DDR4 or DDR5?

We currently offer two main types of laptop and desktop computer memory - DDR4 and DDR5. The main difference here is speed - DDR5 significantly increases data transfer speeds, starting at 4800 MT/s and scaling up to 8800 MT/s, while DDR4's maximum standard speed is 3200 MT/s. DDR5 also uses 64-gigabit memory chips, while DDR4 uses 16-gigabit chips, leading to higher capacity sticks. Meanwhile, DDR5 has less power consumption by operating at a lower voltage (1.1V) than DDR4 (1.2V). As a result, DDR5 has the potential for higher frame rates and improved latency especially in demanding games.

RAM for gaming

When it comes to gaming, the amount of RAM you have can directly impact those high scores and lap times. For most modern games, 8GB of RAM should be enough to get you started. But if you want a more seamless experience, 16GB of RAM can handle demanding games with lots of things going on behind the scenes.

16GB vs 32GB RAM? If you're a serious gamer or want to future-proof your setup for the next generation of games, stepping up to 32GB can offer smoother gameplay and faster load times. On the other hand, 64GB of RAM is usually more than enough for gaming alone, but it might be helpful if you're also streaming or running other heavy programs while gaming.

Is DDR4 RAM backward compatible with DDR3 motherboards?

No, DDR4 RAM isn't backward compatible with DDR3 motherboards. RAM and motherboards are designed to work together with specific technologies and standards. DDR3 RAM and DDR4 RAM have different connectors, voltages, and speeds. So, if your motherboard supports DDR3 RAM, you'll need to stick with DDR3 unless you upgrade the motherboard as well.
