If you bought RAM advertised above the default speed and your motherboard supports it, enabling XMP, AMD EXPO, or DOCP in the BIOS usually delivers the performance you paid for with one setting. It is most sensible for gaming and productivity PCs where the RAM kit is on the motherboard’s Qualified Vendor List. You should avoid it if stability is critical, the hardware pairing is unverified, or the system is a locked prebuilt where overclocking may affect support. Before enabling, verify compatibility, plan a way to reset BIOS if it fails to boot, and be prepared to run a stability test.
