Better check Intel's Memory Compatibility List .... > 50% of the RAM on there is 1.65 volts
I wish peeps would stop spreading this misinformation and actually go read the Intel site. The Intel 1.5 recommendation is for JDEC profiles ONLY because that is all that JDEC has approved..... when you see DDR3-1866 for example "on the package" what they are advertising is NOT the JDEC profile but the XMP profile speed and XMP Voltage. I don't know anyone who runs JDEC....every machine I have built uses the XMP profile.

Intel® Extreme Memory Profile (Intel® XMP) allows you to overclock compatible DDR3 memory to perform beyond standard specifications. It’s designed to enhance the gaming features built into Intel® technology–based PCs. If you like to overclock and squeeze as much performance from your PC as possible, then memory based on Intel XMP gives you that extra edge you need to dominate—without breaking a sweat.
Every single RAM stick on Intel's Certified Compatibility List above 2133 is 1.65 volts .... no exceptions. If you are going to have very low CAS
or very high speed, the way you get there is to use XMP profiles and more voltage. There is absolutely nothing to worry about here.

At JDEC 1333 CAS 9, 1.35 is easy..... CAS 7 will take you higher .... DDR2400 will take you higher
Many peeps go 1.8 volt and higher with narry a worry about DRAM voltage....others go to 2.0

By all means .... if you are using run of the mill memory look for the lowest voltage you can find.... but if you are sacrificing performance just to get a lower voltage when it will provide no advantage whatsoever, that is just silly. RAM, regardless of what it says in the newegg description can be run at various voltages depending on what perofrmnace level you want to obtain.
My DDR3-2400 has the following options:
JDEC #5 = DDR3-1366 @ 9-9-9-24 / 1.5 volts
JDEC #6 = DDR3-1522 @ 10-10-10-27 / 1.5 volts
JDEC #5 = DDR3-1666 @ 11-11-11-30 / 1.5 volts
XMP-2400 = DDR3-2400 @ 10-12-12-28 / 1.65 volts
Notice what a little voltage did .... it overclocked the memory "as supported
and certified by Intel" and took it from 1666 to 2400 and dropped the timing s at the same time. Use CPU-z t see what your numbers are.
I won't be in the same room with a H series cooler.....
Watch the video to see if the noise is acceptable to you

Note here that when compared with the Phanteks, when both use the same paste, the Phanteks scores a temp of 51.75
with quiet 1200 rpm fans compared with the H100's 52.5C
with noisy 2600 rpm fans
Here again the H110 scores the same temps as the cheaper Noctua DH-14
The key here is .... with so little price difference between 1600 and 2400 , why get 1600 ?n Here's a site that is a bit expensive so ya may not wanna shop there but shows a good comparison
http://www.ramexperts.com/ddr3/performance-desktop.html
DDR3-1600 (16GB) CAS 8 / 1.50V = $199.99 (5.00ns)
DDR3-1866 (16GB) CAS 9 / 1.50V = $189.99 4.82ns)
DDR3-2133 (16GB) CAS 9 / 1.65V = $209.99 (4.22ns)
DDR3-2400 (16GB) CAS 10 / 1.65V = $219.99 (4.17ns)
Given the above, .....
.... The 1866 is 4% faster than the 1600 for less money .... no brainer
.... The 2133 is 14.2% faster than the 1866 for just 10.5% more money ... not hard to justify
.... The the 2400 is a lil faster than the 2133 for just $10 more.
Keep in mind that comparing performance increase while simple is a fool's errand in the sense that ya whole system goes faster .... that last one for example should be viewed as a $20 system price increase on say a $2k build for the 2133 is a 14% performance increase for 1% more system cost.
