Problem is frome stock voltages on no-tasks mode, psu is fine.... in HWiNFO64 my CPU Core Voltage (SVI2 TFN) is up to 1.57v - i dont now why is so much for 3.699MHz, decision for that moment is disabled global c-states - noise gone.]]> Sat, 10 Jun 2017 05:44:37 +0000 https://forum.asrock.com/forum_posts.asp?TID=5314&PID=30810&title=electricity-noise-on-x370-taichi#30810 <![CDATA[Electricity noise on X370 Taichi : parsec wrote: andRocky wrote:Hello...]]> https://forum.asrock.com/forum_posts.asp?TID=5314&PID=30501&title=electricity-noise-on-x370-taichi#30501 Author: andRocky

After canceling is starting again. Someone have decision this problem? Ahh ya processor runs a stock frequency (in Auto).


That sounds like capacitor or inductor noise from components in the CPU's VRM stage, from CPU power saving options (Cool n Quiet, C States) being enabled, and a PSU with high DC ripple in the +12V rail.

What model of PSU are you using?

The noise is gone during stress testing because the CPU is under high loads and not in a higher C State power saving mode.

Very high frequency noise like this can be very difficult to know where it is coming from. Why are you sure the noise is coming from the area near the CPU? The PSU can make noise like that too. Is the board inside a PC case?
My PSU is Seasonic Platinum 660W (SS-660XP2). I run system without case on stand and hearing that noise is a VRM zone, not shure is CPU - maybe capacitors ya ... nothing change on bios options, try some CPU saving options disabled.
