Elektrisch induzierte Geräusche im Abit IP35 PRO, die bei diesem Mainboard nicht nur in Einzelfällen auftreten sollen, bringen mich leider vorläufig von meinem Vorhaben, das IP35 PRO anderen Boards in der gleichen Liga vorzuziehen, ab.
Die Beschreibung des Problems findet man bei einer Google-Suche unter folgendem Stichwort:
IP35 Pro & electrical noise
Interessant ist schon der erste gefundene Link zu einer umfangreiche Diskussion des Fehlers im amerikanischen Abit-Forum:

Für einen Schnelleinstieg eignet sich dort der Beitrag Nr. 47.
Ich fasse hier besonders informative Beschreibungen des Fehlers stichpunktartig zusammen:
- high pitched whine is coming from the motherboards Foxconn keyboard/mouse port
- I am hearing the noise (high pitched whine)
- somekind of "klank" noise from the motherboard clear and loud // Schreibfehler "clank" ist gemeint.
- The only "technique" I've found to stop the whine is to apply pressure directly to the port housing itself.
- The noise (high pitch whine originating from the PS/2 port housing) occurs both at stock and overclocked speeds.
- I noticed that if I set the polling rate of my mouse (USB Logitech G9) to 1000 (the max) I could actually control the generation of the noise to some extent.
- I get this tinny noise coming from the PS/2 ports
- I can squeeze it and the noise goes away - odd!
- I am not quite sure it's the PS2 shield that is making the noise, but rather the large inductor that is right next to the PS2 port. It almost sounds like the inductor is making a very high frequency vibration and the PS2 shield is resonating because it's so close and the metal shield is pretty thin.
- Here's a picture of what the inductor near the PS2 port looks like:

- Manipulating the PS/2 port housing (e.g., via the application of pressure directly to the PS/2 port housing) on two new IP35 Pro motherboards affected the noise and specifically affected whether the noise was generated or not. I've tested this ad nauseam, other have witnessed me test this in person and at least one other person on this forum has verified this finding.
- Simply put, regardless of what roll the PS/2 port housing plays in this issue the fact of the matter is that it does play a roll.
- The noise isn't super loud. Try running OCCT, then put your ear up to the ps/2 port. You'll hear a tinny, electrical sound.
- weird noise when moving around mouse
- I have got it to stop! I gave the Foxconn box a real good squeeze and push, and voila no more noise!
EXCEPT!..............................When overclocking!
- While two noise sources (inductor and audio output) may have a related cause, quieting the inductor won't necessarily (probably won't) remove ripple current from the audio subcircuit. A sound card is the typical resolution for that
Ich möchte hier die Diskussion über diesen Fehler im deutschsprachigen Raum anregen.
Wer kann aus eigener Erfahrung berichten?
