I've just begun experimenting with overclocking and managed to push my 4790k to 4.9ghz at around 1.297v. I understand warnings about exceeding 1.3 and the idea that 1.35 might be the maximum. It seems stability matters more than pushing higher, as long as the CPU stays cool. My current idle temps are between 30-35°C, gaming temps 50-55°C, and under heavy load up to 70-73°C. I don’t plan to run at full capacity often, so I’m not overly concerned about temperatures. How safe am I to go beyond 1.3 or 1.35?
Max voltages for a 4th gen i series 22nm chip are around 1.3v (4770k/4790k). Values near that range, like 1.297v, combined with electro-migration under high current and adequate heat, will significantly reduce CPU lifespan and may trigger instability over time. I recommend lowering the OC and keeping the core voltage at no more than 1.25v. The drop in FPS now is better than the future loss when the CPU fails.
The issue arises because you're seeking even greater overclocking without subjecting the CPU to intense workloads. In essence, temperature becomes a limiting factor as soon as it becomes consistent. How do you track the CPU's temperature? Consider factors such as material quality, voltage, current, and duration.
The discussion addresses the reason for seeking even greater overclocking despite not pushing the CPU under heavy stress. Temperature becomes a limiting factor once readings become inconsistent. The methods for tracking CPU temperatures include considering material properties, voltage, current, and time. Overclocking is primarily driven by performance in games like Arma 3, where it has significantly improved results. The focus now shifts to achieving maximum stability and higher temperatures. Monitoring tools such as Afterburner and CPU-Z are used for this purpose.
The discussion addresses why someone seeks even greater overclocking despite not pushing the CPU under heavy stress. It highlights that temperature becomes a limiting factor once readings become inconsistent. The methods for tracking CPU temperatures are mentioned, including Afterburner and CPU-Z. The conversation notes that Arma 3 is quite demanding on the CPU and can easily bring any four cores to their limits. RealTemp is recommended for core temperatures, with a standard threshold of 1.2 V. Going beyond this suggests a solid cooling system and monitoring tool.

I obtained mine (4790K) at 4.6ghz with 1.25v on a z87 gryphon from Asus, but beyond that it became unstable for me. Are you using a z97 motherboard? Your setup is fine, but at that voltage it will likely fail soon. I’d lower the voltage and possibly reduce the overclocking.
