What it means
Your RAM ships running slower than the speed printed on the box. XMP is the BIOS switch that turns on the speed you already paid for.
More detail
Intel boards call it XMP; AMD calls it EXPO; some ASUS boards say DOCP — same idea, one toggle. It gives real gains in CPU-heavy games and steadier 1% lows. If the PC won't boot after enabling it, clearing CMOS puts everything back to default.
