and keep it under
Average is hard to say, but 4.7 under 1.3 is decent, over 1.4 is not. No one knows what is safe, there is no evidence of measurable Ivy degradation by just normal everyday use at a high voltage like 1.5.
We know degradation always happens and the electromigration is hastened by voltage and heat. The higher your voltage the better your temps need to be. Ivy chips are less stable at higher temps also, so I like to keep my max Prime95 testing temps at 80c or below.
You should be safe in the low 1.4 range if temps are good. In the 1.50s you are taking a risk but no one knows how much risk. If you want the chip to not have noticeable degradation for 5 years that is a different situation than upgrading in two years.
