DDR4 RAM: A simple upgrade for compatible PCs

DDR4 RAM is still a strong value choice for many desktop PCs. It gives your system more working space, so it can handle apps, files, tabs and games with less strain. Before buying, check if your motherboard supports DDR4, as it won’t fit a DDR5 slot. You’ll also want to check the supported speed, capacity and number of memory slots.

Choosing 16GB or 32GB

16GB DDR4 RAM is a solid choice for work, study, browsing, streaming and many games. Step up to 32GB DDR4 RAM if you edit photos or videos, play newer games, stream, code or keep lots of apps open. Think of it like a bigger kitchen worktop; the more space you have, the easier it is to keep everything moving.

What affects the price?

DDR4 RAM prices can vary by brand, capacity, speed, heat spreader design and whether the kit includes RGB lighting. Higher-capacity kits tend to cost more, while plain designs can offer better value if you care more about performance than looks. Match the memory to your PC first, then compare price, delivery and warranty.

Frequently Asked Questions

Yes, DDR4 is still a good choice for many desktop PCs. It suits everyday tasks, work, study, browsing, streaming and gaming on compatible systems. You can compare more sizes and brands in our full desktop PC memory range.
No. DDR4 and DDR5 use different slots, so they are not interchangeable. If your motherboard supports DDR5, browse DDR5 desktop PC memory instead.
For most UK shoppers, 16GB is enough for daily use. It suits web browsing, video calls, office work, streaming and many games. If you often run heavy apps or keep lots open at once, 32GB may be a better fit.
32GB is worth it if you game, stream, edit videos, use design tools, code or run several demanding apps together. It gives your PC more breathing space and can help it feel ready for longer. Browse 32GB DDR4 desktop memory if that sounds like your setup.
