Safe voltage for D9GMH?

[Craftyman.]

I have a pair of G.Skill GBHZ-PC6400 (almost certain they are Micron D9 :confused:) with active cooling on them, what is a recommended safe voltage? I'm currently at 2.2v

My Crucial is warranted to 2.2v. Ive read not to take them above 2.3 or 2.4, no matter what cooling you have on them because Micron chips dont like voltage. They clock well with it, but it kicks them in the nuts in terms of lifespan.

Alright thanks a lot. will just keep them where they are then :)

I have an 80mm blowing on mine with them at 2.15v. Theyre not warm to the touch, even feel cool, but Im not going to put any more voltage in them because I want to keep these for a while.
