What Is XMP and EXPO?
For UK gamers aiming to squeeze the most FPS out of their PC build, understanding XMP (Extreme Memory Profile) and EXPO (Extended Profiles for Overclocking) is essential. These are pre-tested memory profiles built into RAM modules that allow your memory to run at its advertised speed, timings, and voltage automatically no manual tuning required for standard performance.
XMP is designed for Intel platforms. Enabling it in your BIOS instantly sets DDR4 or DDR5 RAM to its rated frequency, improving frame-time consistency and potentially increasing FPS in CPU-bound games. A solid UK option is the Corsair Vengeance RGB 32GB (2×16GB) DDR5‑6000MHz, which supports XMP for Intel builds:
