The term refers to issues where a system fails to boot properly within the BIOS settings.

In recent days I experimented with overclocking my FX 6300 on a GA 78LMT USB3 rev 6 using a Hyper Evo 212 LED. Now I realize that inexpensive motherboards aren't the best choice for this task, but I had to make the most of what I have. Later in the process I pushed it to 4.4 to 4.5 at 1.4 to 1.5 volts, ran Prime95 and other benchmarks for 24 hours without issues. But when I power off or restart my PC and turn it back on, it shows "system has experienced boot failures, because of overclocking." I don't know if the clock is stable, but the results are confusing. Anyone with inside knowledge? Any advice?

Check the video link provided. It suggests you might need to adjust settings and consider your hardware differences. Higher voltage can boost power but also increases CPU wear, heat, and stress on the motherboard.
Hi, thank you for the advice. I followed the instructions closely—using 4.4 at 1.4750 volts. But I’m still confused.
Your components are different; your CPU might not handle the same overclocking as mine, or the power supply might not deliver consistently.
You should aim for a stable speed first, like 4.2GHz, and test it for a week to confirm stability.
Each 100MHz increase gives only about a 2% boost, so don’t push for the final 200MHz unless you’re sure it’s safe.
When adjusting the BIOS through Windows, the overclock might function properly. But upon restarting, the BIOS executes tests (POST or Power On Self Test) and may determine that the overclocking parameters are unsuitable. This doesn’t guarantee failure—it simply indicates the system believes the settings won’t work due to its evaluations or error logs. Long-term stress from such attempts could harm motherboard components. In any case, unless you wish to alter settings each time you restart, it’s best to keep your overclock stable.
You can attempt to mimic that approach and observe the results. Keep in mind that increasing voltage boosts power but also puts more strain on the motherboard, accelerates CPU wear, and significantly raises temperatures.

Please note that your components are not identical—your CPU's overclock potential and power delivery may vary.
Focus on finding a stable speed rather than chasing the highest possible frequency. Starting at 4.4 GHz with 1.4750 volts could work; if it functions, test it for a week to confirm stability.
Each 100MHz increase gives only about a 2% boost, so aim for 4.2GHz first and verify performance before pushing further.
Photonboy shared a video link for reference. It suggests experimenting with settings and monitoring performance. Higher voltages boost power but can stress the motherboard, reduce CPU lifespan, and raise temperatures. It’s important to identify your CPU’s stability limits rather than aiming for the highest possible frequency. Starting at 4.2GHz and testing stability over a week is recommended. Each 100MHz increase provides only about 2% improvement, so chasing the final 200MHz may not be worthwhile. The user also mentioned difficulty finding stable results even at standard voltages.
Undervolting is mainly about reducing TEMPERATURE.
Overvolting is about giving enough POWER so that a particular frequency remains stable.
In general, if your cooling is sufficient there's no reason to undervolt.
*Also, FX-6300 minimum under load is 3.5GHz and it should boost up to 4.1GHz. I guess boost for all cores is 3.6GHz based on what you said (there are different Turbo boost levels based on core load).
I'm not sure why you can't overclock more than STOCK though my top guess would be the motherboard isn't providing stable power.
But to be clear, did you try say 3.8GHz and then slowly raise the voltage until its stable?
Photonboy explains that undervolting mainly focuses on lowering temperature, while overvolting ensures enough power for stable frequency. If cooling is adequate, undervolting isn't necessary. He also mentions the FX-6300's minimum load at 3.5GHz and potential boost up to 4.1GHz, suggesting a possible 3.6GHz boost per core depending on load. He questions why overclocking beyond stock is possible, noting his motherboard might not supply stable power. He advises testing 3.8GHz and gradually increasing voltage until stability is achieved, and suggests checking the PSU capacity or considering a full rebuild if needed. He also warns that Turbo Boost is unreliable for gaming.
There shouldn't be any need to rebuild. It's unclear what the issue is, but it might be best to revert to the default settings temporarily. Your CPU or motherboard could be struggling, so testing various settings and voltages might help determine further steps.
