Overclocking CPU with XMP activated
Overclocking CPU with XMP activated
Increasing the voltage parameter does not boost the multiplier or processor speed; it's mainly for stability. To speed up the CPU, provide more power. Exceeding the voltage may cause the PC to shut down, but it won't catch fire.
During my overclocking experience, I allowed the BIOS to manage the voltage automatically. Overclocking involves gradually increasing the clock speed. After booting and running benchmarks or stress tests with CPU-Z, monitor the CPU voltage. Keep testing until stability is achieved and the system runs smoothly. Continue adjusting the clock incrementally until you find the optimal setting.

The maximum voltage the Haswell architecture supports from Intel is approximately 1.25 to 1.27V for the 4790K. This higher stock voltage applies because the turbo reaches 4.4GHz compared to 3.6GHz in the 5820K. It's reasonable to think that voltages under 1.3 are acceptable as long as thermal management is adequate. There are some reports suggesting issues begin around this threshold, with gradual performance drops at higher speeds. Extreme cases can cause instability even at standard speeds or lead to total failure. In the 1.3X range, people sharing experiences are rare, but more frequent in the 1.4X range.
What motherboard was it? If it's an ASUS X99 model, that's the reason. I need to ensure it stays under 1.25V, or else my boards and CPUs will fail. I've had three of each for less than a year. If it's not from ASUS, could you share the details? Clock speed, input voltage, and cache voltage.
