The computer fails to power on following an overclock, does this mean your motherboard is faulty?
I have been using this PC setup for roughly a year and a half, but I haven’t attempted to overclock it until recently. My CPU reached 4.7 ghz (AMD FX-8350), yet I’m still new to the process, so I’m unsure if something went wrong. Although the temperatures stayed low—around 40 to 45 degrees Celsius—the voltage readings felt unusually high, exceeding 1.5 volts, and it remained unstable. Once I adjusted the voltage, my PC shut down, and it hasn’t turned back on since. I reset the CMOS several times and left the battery out for about 15 minutes, but that didn’t resolve the issue. I also checked the power supply to confirm it was functioning properly, and it worked without problems. I’ve excluded both the CPU and PSU as potential causes. Could the motherboard be failing due to excessive voltage? Or am I simply misjudging the situation with my CPU? Thank you for any advice.
Observed several points to consider.
1) 45C feels quite comfortable for Intel, but close to the throttling limit for AMD FX chips.
2) The voltage of 1.5V seems excessive and probably damaged the CPU.
3) The MOSFETs on your board have a big heatsink and are rated up to 115C before throttling and 125C before failure. It's likely your board handled it well.
I noticed a few points.

I was worried that might be the problem, but I checked the specs and it usually works up to 61 C. I feel a bit foolish because I was about to lower the voltage since 1.5V is too high for 4.7 GHz, and something seemed off. Still, I was planning to replace the CPU anyway. Thanks!
61C marks the throttling limit for the cores, while the remaining CPU components must stay below 55°C. Not every program will display the second temperature reading. For overclocking, employ AMD Overdrive to track temperatures and adjust BIOS settings. Unless your processor is extremely low-end, aiming for around 1.33-1.35V should be acceptable.
My take on Vcore on FX chips:
1.29V – pleasant and stylish. Typical when Cool N Quiet is turned off in BIOS without OC.
1.3V – pleasant and stylish. Typical when Cool N Quiet is disabled in BIOS without OC.
1.315V – a bit warmer. Normal for a chip that isn’t binned. Possibly a small OC, but not much at this level.
1.325V – a moderate increase. A fairly standard OC voltage.
1.33V – good OC.
1.35V – excellent OC.
1.375V – aggressive OC.
1.38V – be careful. Think about lowering the voltage slightly.
1.4V – what are you doing?
1.5V – no.

61C marks the throttling limit for the cores, while the rest of the CPU should stay below 55°C. Not every program will display the second temperature reading. For overclocking, use AMD Overdrive to track temperatures and adjust BIOS settings. Unless your chip is extremely low quality, you should have been okay around 1.33-1.35V.
Weberdarren97 shares his thoughts on throttling points and temperature management. He explains that while 61C is the main throttling threshold, the rest of the CPU should stay below 55°C. Not every program displays the second temperature reading. For overclocking, he recommends using AMD Overdrive to track temperatures and BIOS for adjustments. He suggests a voltage range of around 1.33-1.35V unless you're using a very low-quality FX chip, where around 1.33V should suffice.
Weber_deren97 shares his thoughts on CPU temperatures and stability. He mentions that core throttling occurs at 61C, while the rest of the CPU should stay below 55C. Not all programs display the second temperature reading. For overclocking, he recommends using AMD Overdrive to track temperatures and BIOS for adjustments. He suggests a voltage range around 1.33-1.35V unless the chip is extremely low quality, where around 1.33-1.35V should work fine.
He also provides a chart of recommended voltages for various chips:
- 1.29V: Nice and cool, normal when Cool N Quiet is off in BIOS without OC.
- 1.3V: Nice and cool, normal when Cool N Quiet is off in BIOS without OC.
- 1.315V: Slightly warmer, typical for non-binned chips; minor OC possible.
- 1.325V: Slightly warmer, a moderate OC voltage.
- 1.33V: Good OC.
- 1.35V: Excellent OC.
- 1.375V: Aggressive OC.
- 1.38V: Caution advised; consider lowering the voltage slightly.
- 1.4V: Unclear purpose, possibly a test value.
He concludes that for better stability, ensure you monitor both core and CPU temperatures correctly. He also asks about BIOS power-saving settings before overclocking and whether he used BIOS or software tools during the process.

He also provided his own observations on Vcore settings for FX chips: temperatures ranging from 1.29V to 1.38V are considered normal, with slight variations depending on whether Cool N Quiet is enabled or disabled and the absence of OC. He described a few specific voltage levels and their typical effects on performance.
Was es wirklich deinen Prozessor getötet? Ich hatte dieselbe Einheit, erreichte gestern 70°C und alles funktioniert einwandfrei, aber ich habe nicht 1,5 Volt verwendet.
