Modern PC hardware often has more interlinked elements than the average user can keep track of. Sure, seasoned gamers may know about XMP/EXPO, Resizable BAR, and GPU power limits, but the majority of users are unaware of these settings. I want to highlight some other PC settings that directly impact your gaming performance, thermals, noise levels, stability, and security. You may not know these settings exist, or even if you do, you may not consider them worth the hassle. Some users are also overly cautious about fiddling with the firmware, BIOS settings, and voltage/frequency settings out of fear of lasting damage. Thankfully, the settings on this list are perfectly safe to tweak, and will almost always deliver positive results for your system. The default settings might work, but you’re unknowingly leaving performance on the table.
