这个1.55V是能保证CPU功能和可靠性的最大电压。通常不推荐加到这么高。英特尔设计要求核心真实电压值不能超过这个值,再考虑主板的误差和CPU的误差,设为1.4V以下应该安全。1.35V更加保险。看看英特尔怎么说的:
At conditions outside functional operation condition limits, but within absolute
maximum and minimum ratings, neither functionality nor long-term reliability can be
expected. If a device is returned to conditions within functional operation limits after
having been subjected to conditions outside these limits, but within the absolute
maximum and minimum ratings, the device may be functional, but with its lifetime
degraded depending on exposure to conditions exceeding the functional operation
condition limits.
