Desktop RAM (DDR4 / DDR5)

Memory is one of the simplest upgrades you can make, and one of the easiest to get wrong. If you are buying DDR5 RAM in the UK, the first rule is to check what your motherboard supports: DDR4 and DDR5 are physically different and not interchangeable. For gaming desktops in 2026, 16GB is the workable minimum and 32GB is the comfortable choice, especially if you keep browsers, Discord and background apps open while you play. Speed and latency both matter, but capacity comes first: 32GB of mid-speed DDR5 beats 16GB of the fastest kit on the shelf. Buy memory in matched kits rather than mixing sticks, and check your motherboard's QVL list if you plan to run high frequencies. Taller heatspreaders look great but can clash with large air coolers, so measure before you commit. Rig & Revive supplies desktop memory to UK customers from Swansea, South Wales, with kits to suit everything from budget builds to high-end rigs. Unsure how much RAM your system needs or whether your board takes DDR4 or DDR5? Ask our team, or spec the memory as part of a balanced build in our PC builder and we will make sure it is right.
