The 1.5 (+) that Intel talks about is for DRAM running at the spec freq of 1600, I tend to stay at 1.5 sticks up through 1866, from 2133 on up 1.6-1.65 is perfectly fine (and expected as the freqs are higher and it is anticipated using these higher freq sticks you will be running an OC on the CPU, I myself like to keep the DRAM and MC voltage within about 0.60 of each other)

I am getting conflicting answers in regards to the Haswell and the 1.65v memory. Some say you will not have an issue while others say I should not go over the 1.5v? Anyone use 1.65v in their haswell processors?

I do yes. It will be fine. I have G.SKILL Sniper Series DDR3 SDRAM DDR3 2400 1.65V and it runs perfectly with my haswell (4770k). The memory you picked is RATED to run at 1.65v which means they have tested it and confirmed it runs at that (lifetime warranty).
