DDR4 vs DDR5 for Gaming

DDR5 has matured significantly since its 2021 launch. With speeds starting at 4800MHz and going beyond 8000MHz, DDR5 offers higher bandwidth and better power efficiency than DDR4. However, DDR4 remains a solid choice for budget builds, with 3200MHz and 3600MHz kits offering excellent price-to-performance ratios. For new builds in 2026, DDR5 is the clear recommendation — the price premium has shrunk to just 10-15% over DDR4 equivalents.

How Much RAM Do You Need for Gaming?

For most modern games, 16GB is the sweet spot. However, some titles like Cities: Skylines 2, Star Citizen, and modded games benefit from 32GB. If you multitask while gaming (streaming, Discord, browser tabs), 32GB provides headroom. 64GB is overkill for pure gaming but useful for content creators who game.

The Corsair Vengeance DDR5-6000 (2x16GB) offers an excellent balance of speed and compatibility at around £65-75. For AMD Ryzen 7000/9000 builds, DDR5-6000 hits the FCLK sweet spot for optimal performance.

XMP and EXPO Profiles

After installing new RAM, you must enable XMP (Intel) or EXPO (AMD) in your BIOS to run the memory at its rated speed. Without enabling these profiles, your DDR5-6000 kit will run at the default JEDEC speed of 4800MHz, leaving significant performance on the table. Access your BIOS by pressing DEL or F2 during boot, navigate to the memory settings, and enable the appropriate profile.
