Read your own question again, with emphasis as shown.

In other words, pretty much zero, if you want it to operate as
advertised.

The motherboard manufacturer, BioStar, wouldn't guarantee against
damage even if I never exceeded the chip maker's maximum absolute of
2.3V, nor would they guarantee that the voltage applied to the memory
would never go above that by itself, such as because of a glitch.
