All DDR4 and DDR5 RAM runs at base JEDEC speed by default — typically DDR4-2133 or DDR5-4800. To reach the advertised speed, enable an overclocking profile in BIOS. This is completely safe and intended by manufacturers.
XMP vs EXPO

Intel XMP and AMD EXPO are one-click overclocking profiles stored on your RAM. Enter BIOS, find XMP/EXPO, enable it, and your RAM runs at its rated speed. No manual tuning required.
Manual RAM Tuning
For enthusiasts, manual overclocking squeezes 5-15% more performance. Key timings: CAS Latency (CL), tRCD, tRP, tRAS. Start with primary timings, stress test with MemTest86, keep voltage under 1.4V DDR5 / 1.45V DDR4.
