Issues with boosting an Intel I5 4690k to 4.5 Ghz
So I purchased the I5 4690k about a month ago, intending to overclock it to around 4.5 or 4.6 ghz. I followed some guides on CPU overclocking and thought I could reach 4.5 ghz with 1.3 V. However, when I accessed the BIOS and set it up for 4.5 ghz, my PC wouldn’t even start—just constant restarts lasting about 10 to 15 seconds each. As a beginner in overclocking, I’m wondering where I went wrong. The default BIOS settings worked fine, but others suggested my PSU might be insufficient (550w FSP Raider). My opinion is still unclear, as mixed opinions exist.
A top-notch PSU is crucial for successful overclocking, ensuring a consistent and clean power source. Your current unit is quite basic. Additionally, there are no assurances when it comes to overclocking; some components perform exceptionally well while others struggle significantly. It's advisable to gradually increase the speed by 0.1 Ghz at each stage and conduct stress tests after each adjustment.
When I had my 4690k, the only thing stable was 4.5 ghz. Even then I reduced the multiplier to 43 to lower voltage and manage temperatures. You might want to try similar adjustments, starting at 40 and gradually increasing until it stops booting, then reduce the multiplier back by one. Personally, I prefer keeping below 1.3V, ideally around 1.25V maximum.
