Squeakin, whistling noise from motherboard MA78G-DS3H
Motherboard MA78G-DS3H 1 year old, about 7 months only in daily use.
Since yesterday I hear a squeaking, whistling sound with constand frequency from the motherboard. At first I was afraid the sound would announce impending harddisk death but definitely the sound does not come from any moving part like hard disk, fans, DVD-drives, power supply. What might that be, can I do anything except trying to get a warranty exchange of the whole board? I don´t feel any interest to set up the computer again after 1 year with another motherboard. The MA78G-DS3H would be still available so changing that would be the easiest trick. Franz47 |

Squeakin, whistling noise from motherboard MA78G-DS3H
I have a similar issue with a different motherboard, a Gigabyte GA-EX58;
my sound is not constant, it varies (A LOT) depending on what the system is doing. I hear chirping, whistling, various high pitched (ALMOST inaudible) tones and, occasionally .... silence. The sound is almost certainly coming from the magnetics (coils) of the switching power supply for the CPU that is on the motherboard. The ferrite cores of one or more of the coils are "vibrating" at very high frequencies (main power supplies sometimes do this also). It shouldn't happen, but those coils were not properly "potted" when they were made. In my opinion it should be covered as a warranty claim, and my board is still in warranty. The problem is, I am unwilling to be without a system for 3 weeks, not to mention the HUGE effort involved, so I'm putting up with it (not happily, however). But a manufacturer might deny it because, electrically, it works fine (and it does; it is not a risk to the operational ability of the system, it's just annoying as hell). franz47 wrote: Motherboard MA78G-DS3H 1 year old, about 7 months only in daily use.

Some motherboards have software for controlling the operation of Vcore dynamically. Perhaps removing that software, making changes to settings, might alter the noise you hear.

Squeakin, whistling noise from motherboard MA78G-DS3H - Solution
Yesterday I already thought about another possibility. When changing the booting
sequence in the BIOS I had also gone through other BIOS values and changed the temperature and fan alarms from off to on. The sound came from the little sound gadget, which nowadays replaces the case loudspeaker and is plugged onto the motherboards where you attached the case loudspeaker cable in earlier days. The AMD CPU and mobo software keeps the fans standing still when temp is low so some of these alarms, only the fan under the HDD is on all the time. This makes a perfectly quiet PC. I turned the alarms in the BIOS off and the sound was gone again. Thanks for all the input. Franz47 |

Well, unfortunately, that is not my problem.

If this noise is like that coming from a bunch of bird nests in springtime, then here's what fixed it on my board. Boot up, go into the bios del, and navigate to the Integrated Peripheral menu. Then set C1 state control and E.I.S.T. to disabled. Doing this will turn off power throttling. If you monitor your CPU Core voltage, you will see constant. -- Mark |
