What is safe max voltage?
Hello, the cpus architecture safe max voltage refers to the electrical limit that protects the processor from damage due to excessive voltage. It ensures the chip operates within safe parameters even under stress conditions. Your experience shows stable performance at a slightly higher voltage (1.38V) for years without overheating or issues, which supports the idea that 1.35V is the recommended safe threshold. The difference lies in how the design accounts for real-world usage and thermal management, allowing short-term operation above it without harm.
Typically "safe" voltage refers to long-term use. It changes based on the CPU model. Increased voltage often causes CPU wear and can lead to performance loss. This happens due to various intricate reasons, making it hard to reverse and requiring more extreme voltages for stability. Certain processors eventually reach a limit where higher voltages aren't feasible. Some factors include temperature, silicon properties, and atomic-level events. I remember that as temperatures drop, the safe voltage tends to rise. Those with deeper expertise can adjust settings accordingly.

The amount of current flowing through the CPU determines its failure, and voltage-current behavior changes with temperature. At 1.8V it can destroy the CPU rapidly under normal conditions, but extreme cooling like liquid nitrogen might prevent it. Still, a clock speed of 4.5GHz is quite low.
I understand these chips support 5GHz, but the real concern is the heat output. Four point five is quite moderate, though temperatures can quickly rise. I recall my 3770k handling around 4.8 volts—it would require more than 1.45 volts to maintain stability. Those temps were far beyond what I could manage at those settings.
Temperature? For Haswell it hinges on whether you're using the original paste or switching to liquid metal (delidding). 5G efforts mostly rely on liquid metal... Yet I still anticipate 4.7GHz without delidding. The issue with paste is clear, but at 22nm you'll quickly exceed 1.4V.
