Hey, I'm doing my first computer build and I have everything selected except the RAM. I'm planning to use an MSI Mpower Max and an Intel i7 4770k with a Noctua NH-D14 CPU cooler. Now the issue lies in the voltage of the RAM. I wanted to get some G Skill Ares Series 2400MHz because it was cheap, fast, and low profile enough to fit under the gigantic DH14, however after reading online I keep finding people crowing about how 1.65v RAM will void the warranty on my i7 and shorten the processor's life. After reading many accounts of people running 1.65v RAM with an i7 I'm sure this wouldn't burn it up but I do NOT want to void my warranty on day 1. (Even though I can't imagine how Intel would know I was using 1.65v RAM) So hopefully someone can clear this up for me. Right now I can't even find any 2400 MHz ram that runs at less than 1.65v and is low enough to fit under my CPU cooler so I'm in a bit of a jam. Thanks in advance for the help and if someone could link me to the part of the Intel warranty that actually says higher than 1.5MHz RAM will void it, I would really appreciate that.

Intel i7 4770k
MSI MPower Max
Asus Radeon r9 280x
Corsair HX-750

Edit: I see this is a common question. I'm mostly interested in the rumor that it would void your warranty.

People argue all day over this with regards to Haswell. However, the general consensus is the highest speeds are only really noticeable on benchmarks. So I'd say you'd be fine to get those 1866 sticks.

No one can tell what voltage you've run your RAM at, if you don't tell them, they'll never know. A lot of high end RAM runs at 1.65v and is perfectly safe for CPU longevity, so if that's the stuff you want, buy it.

Well I did some more reading and I wound up finding a really good deal on two 4GB sticks of Ripjaw X Series 1866MHz 1.5v so I ordered those. Will there be a noticeable difference between the 1866 and the 2400? The cas latency on the Ripjaws is 9 where the Ares is 11 I believe.

Edit: I plan to use this computer for gaming, CAD, and some rendering.
