Overclocking 4770k with overclocked RAM?

Solution
No, you will have no problem unless you overclock the northbridge. If you just change the cpu multiplier and voltage you'll be fine with what you have.
So the RAM being at 1.65v won't affect the overclocking of the CPU at all? Tradesman1 told me the same thing yesterday, but I keep seeing varying information so I just wanted to double check.
 
Yeah, Tradesman1 is VERY knowledgeable when it comes to RAM. Whatever he told you is right (and I have happened to tell you the same thing). The RAM will not affect the multiplier based CPU overclocks.
