1- Corsair Vengeance Pro CMY8GX3M2A1866C9 1866Mhz 9-10-9-27 runs @ 1.5V

2- Corsair Vengeance Pro black, CMY8GX3M2B2133C9 2133Mhz 9-11-11-31 runs @ 1.65V

CPU: i7 4770K Heswell
MB : Asus MAXIMUS VI HERO

Both ram available locally for me and price very close I like the 2133 but I am worry from 1.65V
 
Solution
The 1.65v RAM is out of spec for the memory controller on the 4770k. Yes you can run 1.65v memory with Haswell CPU's but given the choice I would stick with 1.5v memory or less.
