Memory voltage with Kaby Lake 7700K/Z270

[Fixadent]

Someone said that having memory voltage above 1.2V will greatly decrease the lifespan of your integrated memory controller.

Is this true?

The memory kit I want (G.Skill Triden-Z RBG 16GB DDR4) runs at 1.35V

Who said that? I highly doubt it, I run my memory at 1.35v, have since about a month after kaby lake came out and everything is fine. There are kits that run at 1.4v without issue, hardcore overclokers push 1.5v or more and it doesn't kill the memory controller. So I doubt 1.35v is going to "greatly decrease the lifespan of your integrated memory controller". I guess we will find out in a year or so if everybody's skylake/kaby lake memory controllers start dying out of the blue, since most kits advertised at 3000mhz+ are using 1.35v or more.

I read that the Skylake/Kaby Lake memory controllers are very robust. Is that true?

Then you are reading some contradictory things, it wouldn't be very robust if it couldn't handle 1.35v. I dont really know how robust it is, seems pretty good to me it allows for some impressive DDR4 speeds and timings. I'm am not sure how it compares to previous intel generations, never did to much memory overcloking on platforms that used DDR3 nor have I read much about it.

first off a .1 volt is not a lot of voltages. if you looked at 50 cpu bios voltage screens depending on how good the cpu chip and mb are most mb are going to be above or below the stock ram voltage by .1 the older cpu that came out on z170 mb with ddr3 ram had to run at 1.35v. intel stock speed and voltages are used mostly for oem and non gamers so that they can pick up stock parts and have a pc last for years without upgrading or replacing parts. as with ddr3 and newer ram that drops. the first chips are slow and when overclocked need higher voltage. as the ram vendor make newer rev of the ddr4 chips they going to get faster and use the same 1.2v.
