What Type of Desktop RAM Do You Need?

There are several different types of PC RAM available and the right RAM for your PC will depend on your performance needs. You'll want to consider whether you need DDR4 or DDR5 RAM, the RAM capacity and speed.

What's the difference between DDR4 vs DDR5?

DDR4 and DDR5 are the most common RAM types for modern PCs. Both will be compatible with a wide range of builds, but their performance features vary considerably.

How Much RAM Should a PC Have?

How much RAM capacity your PC needs, will depend on what you mainly use your PC for. Here are our recommendations:

8GB - 16GB: 8GB would be considered the absolute minimum RAM capacity for a modern PC build and only suitable for basic, everyday tasks like web browsing, HD video streaming, emails or word processing. 16GB will give you more power and is great for those working on larger files or presentations, whilst still keeping costs low. Check out the Crucial 16GB DDR4 3200MHz RAM for a budget-friendly buy.
32GB - 64GB: This mid-range capacity is great for those looking for a balance between performance and price. 32GB is perfect for gamers, whilst 64GB is best for advanced content creators using creative software like Adobe Creative Suite or higher-end production tools. Computer RAM in this capacity range will give you smoother performance perfect for multitasking. Check out the CORSAIR VENGEANCE 32GB DDR5 6000MHz RAM for our recommended best buy.
64GB+: This would be considered the higher-end PC RAM capacity, recommended for those seeking ultra-high performance builds and top-tier performance across 4K monitors. Great for professional content creators, AI enthusiasts or developers working with 3D models. Check out the Kingston FURY Renegade 96GB DDR5 6000MHz RAM for an ultra-high-performance choice.

What speed RAM is best for a PC?

RAM speed, also known as the clock speed, is measured in MHz. This is how fast the RAM can transfer data - with a higher speed indicating higher system performance and efficiency.

With DDR4 RAM, we recommend looking for a clock speed of at least 2666 MHz for casual, everyday tasks and up to 3200 MHz for multitasking, gaming and streaming.
DDR5 RAM boasts significantly higher clock speeds, which is why it's recommended for high-performance users, with around 6000 MHz being the sweet spot for gaming and creative applications.

If you're a gamer, you may want to consider the overclocking capabilities, known as the boost clock speed, which will allow you to push your system to its limits without sacrificing performance.
