We start by examining the concept of overclocking beyond the CPU and GPU to everything in the system, including cooling, RAM, and even peripherals. The video emphasizes the importance of a solid power supply and introduces a Seasonic prime titanium fanless unit as a baseline to minimize noise while maximizing stability. The presenters adjust the mains power configuration, observing voltage drops and how these changes impact power delivery to the system during stress testing. They walk through baseline setup steps, including updating BIOS, OS, and tuning utilities, to ensure accurate measurements before pushing components beyond factory specifications. The CPU overclock is detailed: increasing the multiplier to 51 and disabling SVID, achieving 5.1 GHz across all cores at roughly 1.275 volts, followed by a cache adjustment that unlocks additional headroom up to 4.8 GHz with a modest voltage increase. They report a measurable Cinebench gain from these core and cache changes, setting the stage for broader experimentation beyond traditional CPU tuning.

Questions answered
- What is the first step LinusTechTips takes before overclocking any component, and why is it important?
- They begin with a solid power supply and baseline measurements, including updating BIOS and OS, to ensure system stability and to verify that any gains are real and not caused by instability.
- How did the team improve CPU performance, and what were the resulting clock speeds and voltage?
- They increased the CPU multiplier to 51 and disabled SVID, achieving 5.1 GHz on all cores at about 1.275 volts, then boosted the cache to 4.8 GHz with a small voltage increase.
- What peripherals were overclocked and what were the observed outcomes?
- USB polling rates on mice were increased with firmware tools, up to 1000 Hz for some mice, providing faster input response, while monitor refresh rates were increased via custom resolutions, yielding noticeable gaming improvements when GPU power allowed.
