I need help with my ram sticks :( they are suppose to run at 2400mhz @ 1.65v, but when I try that there is some very annoying sound in the headset, like raindrops on a umbrella but more annoying.
and when I lower the voltage to 1.5v and the ram speed to 1600mhz then it's gone.
Also tried 1.5v 2400mhz and then the sound went all crazy and after that crashed.

It sounds like your motherboard is not be too happy with having to give the memory 1.65V. It's not really that good for the IMC in your CPU either. I would suggest trying some intermediate settings like 1866 and 2133 - it's not going to make much of a difference in performance anyway, espcially if you're able to tighten up the timings.

I guess I should return the ram sticks then since I payed extra to get 2400mhz
EDIT: but the weird thing is that my mobo supports up to 3200mhz :S

That's what I would do. The motherboard manufacturer can claim to support whatever they wish, but the reality is that CPU's memory controller is only spec'd to 1600MHz and 1.5V, so anything above that is higher than what is officially supported by the CPU. Some CPU's can handle huge memory overclocks, but some can't.

MERGED QUESTION
Question from culzone : "Compatible? or not?"

should HyperX Savage DDR3 2400MHz CL11 be compatible with:
https://pcpartpicker.com/user/culzone/saved/#view=FdKJ7P

My processor there is clocked at 4.7ghz 1.33v

been trying for many hours to reach that 2400mhz both with XMP and manually but it does not want to work. I have weird noises coming from the headset while running the 2400mhz and just after some minutes my computer crashes. 2133mhz is fine tho, but you know I want what I payed for :S
