Update safely

Download BIOS from your exact motherboard model page.
Use a UPS or stable power; avoid updating during storms.
Reset to defaults after flashing; then reapply settings.

Memory profiles first

Enable XMP/EXPO for rated RAM speed and timings.
If unstable, drop one step (e.g., 6000 → 5600) or add minor SOC/IMC voltage per vendor guidance.

Power and thermal limits

Set reasonable limits (e.g., Intel PL1/PL2 to cooler capability; AMD PPT/TDC/EDC per board guidance).
Disable Multi-Core Enhancement/Performance Boost Overdrive if temps are excessive; re-enable after cooling is improved.
Fan curves: keep VRM/CPU under 85°C with a smooth ramp.

Stability checks

Run a short memory test (e.g., Windows Memory Diagnostic or MemTest pass) after XMP/EXPO.
Use a 10–15 minute CPU stress (Cinebench / y-cruncher) to confirm thermals and limits.
Game test for 20–30 minutes; watch 1% lows for stutter.

Once stable, you can pursue OC/UV. If you’d rather skip tweaking, pick a balanced prebuilt from our Best Gaming Computers guide.
