i5 4690K Overclocking
My CPU operates at its standard 3.5 GHz, but I aim to push it to 4.2 GHz for a slight performance increase. As long as it remains stable, could you suggest the appropriate voltage settings? It seems every guide I check is outdated and gives conflicting advice. I'm using a Hyper 212 Evo with an i5 4690k.
You definitely don't wish to alter two aspects simultaneously, and applying a constant voltage is mainly intended for testing purposes. Check the CPU performance at 1.25 volts to ensure it doesn’t overheat; if it does, raise the clock speed gradually by one multiplier until it fails, then reduce back to the previous level. Prime 95 at 26.2 or lower is commonly used for testing. For maximum stability, newer Prime 95 or AIDA 64 Extreme versions are preferable, though they should be paired with effective cooling solutions. A reliable reference for Haswell chips exists. You possess a Haswell-Refresh chip, which significantly improves performance at higher frequencies, so reaching your target should be feasible.
Uncertain about how long this information would remain relevant. The highest recommended voltage for daily use is around 1.3 volts. With that, you can easily achieve 4.5Ghz, most of the time. Each CPU behaves slightly differently.
4.2Ghz is just 300Mhz above the standard boost of 3.9Ghz. You might not require a higher voltage if you're fortunate. If not, simply raise it gradually until stability is achieved. Alternatively, adjust it higher and observe instability when reducing it.

4.2Ghz is just 300Mhz higher than the standard boost of 3.9Ghz. You might not require a voltage boost to hit that, if you're fortunate. If not, simply raise it in steps until it stabilizes. Alternatively, try setting it high and observe instability when lowering it.
Sure, a solid strategy would involve using tools like CPUID and a stress tester. For stress testing, consider recommending software that simulates heavy workloads. When lowering voltage, watch for signs such as increased temperatures, unstable performance, or shutdowns.

A useful reference for Haswell chips is available online, detailing how to reach higher speeds safely.
It depends on the luck of the chip you received; everyone's results are different. My 4790K runs at 4.6 1.22 volts. I can get it to run at 4.5Ghz with 1.35 volts, but it heats up fast—up to 100°C quickly, even with water cooling, so I chose 1.29 volts at 4.3Ghz.
