Something was holding my PC performance back, but it wasn't what I expected. I tried adjusting BIOS settings, tweaking XMP/EXPO profiles, and fiddling with anything that could be fiddled with. XMP was inconsistent, memory behaviour was unpredictable, and I spent far too long poking around BIOS settings trying to get things to behave properly. Update BIOS (when there’s a clear reason) BIOS updates often improve hardware compatibility, fix stability issues, and can significantly improve memory behaviour—especially on Ryzen systems.
