Hello guys

I have gotten a good offer on 2x4Gb Kingston HyperX beast 1600mhz ram - but I'm not sure if my mobo will work well with these. I have the Asrock z77 extreme6.

Should i stick with 1,5v ram?
 
Why ? The 1.5 v limitation relates to standard JDEC profiles, not XMP

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.1

Predefined and tested Intel XMP profiles can be loaded via BIOS or a specific tuning application through a computer’s operating system. Often the easiest way to load Intel XMP profiles is using a tuning utility, which may be available depending on the particular board manufacturer. To learn whether a tuning utility is available on your system, you should contact the board manufacturer.

Most, at least last time I looked, listed compatible i5 / i7 RAM is 1.65 .... at least according to Intel's compatibility lists

Intel's approved i7 Compatibilty List (April 2012) includes:

34 1.65 volt modules
