Hello,
so I bought a new Motherboard Asus P8Z77-V LX. First thing I did after booting it into the windows was updating the bios to the latest version.
Later that day I noticed that the motherboard is making a not too loud, but when it's silent in my room I can hear it very clearly, a high pitch noise coming somewhere from the area of CPU and RAM slots.
I investigated alot and found out that it is probably the VRM making the noise, because when the CPU is under load the high pitch noise dissapears.
I verified this by turning all the power saving settings like the C1E,C3 and C6 in the bios and the noise dissapeared but the cpu was very hot even when idle.
So I tried this solution, I downloaded an older version of the bios and after loading default settings of bios and reboot, no sign of that annoying high pitch noise so far.
I then updated again the bios to the latest ver. just to make sure and the noise came back with the latest version, so I reversed back to the older version and the noise is not present so far.
Could it be possible that the newer version of the bios got some "bug" that makes the motherboard make that high pitch noise? Is something like that even possible? Or is my mind just playing games with me?
Thank you
