Safe voltage for DDR4 ?

[Dicehunter]

Want to tweak my memory and was wondering if anyone knew the max safe voltage for DDR4 Micron equipped modules ? I've looked around but found a lot of contradictory information.

There are several Micron chips used in DDR4, any idea which yours is?

According to Thaiphoon it's Micron E-Die which others have said is good for daily use at 1.45 but others have said 1.40v, So much contradictory info out there.
