Audio problem

[Melzo]

Hello,

i have a sound problem with my new assembled pc. When i play music, the audio has this crackling noise. I tried different audio drivers, but that didn't change anything. Sometimes the music plays normally, but the noise starts at some point.

Now i changed my memory voltage from 1.65 to 1.5 (1333mhz) and there's no audio problem anymore. I read that it isn't recommended to use 1.65v memory with my cpu. Can 1.65 voltage cause this problem?

Mobo: Asus P8Z77-V LX2
Memory: Kingston HyperX 2x4GB, DDR3 1600MHz (KHX1600C9D3B1K2/8GX)
CPU: i5-3570K

Most CPU's (and MoBo's) are set to only work with certain voltage RAM sticks using voltage that is too high...or even too low can potentially short the MoBo or the memory modules.
