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.

• DDR4 RAM has long been the standard RAM type for most computer systems, although it is now slightly outdated by the new DDR5. If you're an everyday PC user, a light gamer or a professional primarily using word processing and web browsing, DDR4 computer RAM is perfect. It offers a balance of good performance for a lower price point.
• DDR5 RAM is the newer generation of computer RAM. It delivers exceptional performance and efficiency and is perfect for reducing lag time on games and intense creative workflows. If you're a professional gamer, content creator and anyone using resource-intensive applications - DDR5 PC RAM should be your go-to.

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.

Computer RAM Compatibility

Before purchasing any PC RAM it's important to check that your new RAM is compatible with both your motherboard and other PC components. If your RAM is incompatible, you could damage your computer system.

Form Factor

DIMM RAM modules are the type of RAM used in PC desktops. They are larger and built to be compatible with larger PC motherboards. These differ from smaller form-factor SO-DIMM RAM modules, which are designed specifically for use in laptops only.

Motherboard Support & BIOS Updates

Check your motherboard's specifications carefully to ensure that your chosen RAM type, chipset, speed and capacity are all compatible and that you have enough slots on your motherboard available. You can also use a system scanner tool to identify any issues. Before purchasing it's also a good idea to run the latest BIOS update on your PC. This can improve compatibility with newer types of RAM and will ensure it's running at its designated speed.

RAM for Gaming PCs

For gamers seeking peak performance, choosing the right RAM is essential. Look for DDR4 or DDR5 modules with low latency and high speeds.

• Latency: CL16 or lower latency for DDR4 and CL30 or lower for DDR5
• Speed: 3200MHz+ for DDR4 and 5600MHz+ for DDR5

For added visual flair, RGB lighting features can add an aesthetic touch for custom builds. We could also recommend looking for Intel XMP or AMD EXPO support, which can ensure easy overclocking.

RAM for Creative Workstations

When working with 4K video editing, 3D rendering or large datasets - adequate memory capacity and stability are critical. Opt for at least 32GB+, ideally in a dual-channel configuration. ECC RAM may be beneficial for professional-grade workstations, though most content creators will benefit from non-ECC high-capacity DDR4 or DDR5.

Check out the Crucial 64GB DDR5 4800MHz RAM for creative rig setups.

Budget RAM for Everyday Builds

For general everyday use PCs look for DDR4 2400MHz-3200MHz modules that offer good stability at lower prices. Check out the Kingston ValueRam 8GB DDR4 3200MHz RAM for a budget choice.

FAQs on Desktop PC RAM

Can I mix different brands or speeds of PC RAM?

It is not generally recommended to mix speeds or different brands of computer RAM. Mixing modules can cause system instability, prevent dual-channel operation and default your memory to the slowest module's speed and highest latency. For guaranteed performance, match RAM sticks across brand, speed, latency and capacity.

How much PC RAM do I need for gaming?

The amount of RAM you need depends on the types of games you play and whether you're multitasking or not. 8GB would be the absolute minimum and is only just sufficient for older titles or esports. 16GB is usually the sweet spot for most gamers, allowing a balance of price and good performance across most AAA titles at medium settings. If you want high performance or to future proof, we recommend at least 32GB. Having more RAM won't always increase FPS, but it will improve system responsiveness and future compatibility.

Will DDR5 RAM work in any PC?

No, DDR5 RAM is only compatible with motherboards that support it. DDR4 and DDR5 use different connectors, voltages and memory controllers. To use DDR5, you'll need a DDR5-compatible motherboard (typically Intel 12th Gen or newer, or AMD AM5 platforms) and a CPU that supports DDR5, like Intel Alder Lake or AMD Ryzen 7000 series.
