Haswell RAM Voltage?

The G.Skill Trident X Series 8GB (2 x 4GB) DDR3-2400 Memory operating voltage of 1.65V exceeds the Intel Haswell Refresh CPU recommended maximum of 1.5V+5% (1.575V). This memory module may run at a reduced clock rate to meet the 1.5V voltage recommendation, or may require running at a voltage greater than the Intel recommended maximum.

Anyways, someone commented on a different thread that this meant that by running the ram mentioned above, I could possibly damage my CPU. However, through a few searches, I've found some information.

One piece of information said that I need to overclock my CPU in order to balance the memory controller.

A different one said that I need not do anything at all and the only reason Intel set this at 1.5 is to keep people from running RAM at crazy high voltages.

Any insight?

Additional information: The board I plan to use it on (Asus Maximus VII Hero) supports 2400mhz RAM if overclocked (which basically just means changing the motherboard default to the 2400mhz clock), so it's really just an issue of whether or not I should run it at that speed/voltage.

1.65 is perfectly fine (Intel even certifies numerous 1.65 sets...I stick with 1.5 up through 1866 as there's simply no need for higher voltage with those sets and it can be indicative of weak memory ICs...unless they are very high performance. N, you aren't going to damage the CPU. At 2400, yes there is a possibility of needing a slight OC to run full 2400, that depends on the individual CPU you end up with (silicon lottery) as many say 4690k or 4790K are stronger than others and then too some are weaker than say the 'norm'1.5 comes from the JEDEC standard for 1600 SRAM

Well I will be running the i7 4790k and the only reason I got the 2400mhz is because it only cost 86.99 and I needed some RAM for my system since I'm building a different lower-end system for a family member and I'd rather give them the old 1333mhz RAM I have now.

You'll be fine w/ the 2400, if anything comes up, give me a shout, been running those stick for over 2 years now, have had then on I don't know how many mobos ;)

Pretty much figured that, but this is technically my first build (or rather replacing parts from my first build using the same case) so I'm still cautious.
