[SOLVED] Audio suddently crackling with XMP settings

[clovitox]

[FONT=&quot]Hello, I recently bought a new Corsair Vengeance 2x8gb DDR4 3000Mhz RAM (about a month ago), and a few days after I enabled the XMP profile and it worked very good. I also updated my BIOS like 2 days ago and had no problems.[/FONT]
[FONT=&quot]However, today I was using my PC for gaming and turned it off as i went to lunch, but when I turned it back on later, i noticed there are audio crackling sounds and they are extremely annoying. I went online and find out to disable the XMP profile which I did and now the audio problems are gone. Another solution was to change the PCH Voltage from Auto to 1.1V, that also proved to remove the audio problems, but i dont know if its safe to have it at 1.1 since the default is 1V (but using this value causes audio crackle) so I put it back on auto)[/FONT]
[FONT=&quot]Why did this happen suddently and how can I fix it permanently? Sorry for my english it is not my native language.[/FONT]

Fixed it by lowering the VCCIO and VCCSA voltages. While using the XMP profile and ´´auto´´ voltages, they were too high.

Hey clovitox, you may be my hero!

I have not made out the cause of my audio issues for a long time. Nearly was giving up, trying everything with drivers, different soundcards and so on.. But yesterday I found out there could be a issue with xmp and see there... I changed my ram half a year ago and never thought about this to be the reason for the crackling. Had a corsair dominator before and changed to the corsair vengeance rgb.

So can you tell me at what voltages you set your vccio and vccsa due I have a i7-6700k and this should be near to your settings?
