Thanks for sharing this, but please forgive me my answer: This noise will only happen to coils and electrolytic capacitor. Never had this before with tantalum electrolytic capacitors. Btw. that's what I have noticed @ work (I am a electronics technician). Sometimes this will happen, looks like this will start when the tolerances are reached.
Anyway, glue is not a solution.
I am no electronic technician, but as far as what I know from physics is: whatever tries to make sound must be moving (vibrating). And stopping such a thing by gluing it to the ground can be the answer, especially if the alternatives are to resolder unknown/unidentified pieces of electronic equipment, or start a fight with the vendor in China.. Ask my N100 how it thinks about sending me those nasty and loud 5x beeps while booting. Glue was the answer for that problem, too.
Concerning the constant questions about Bios upgrades: Why? Is there something which doesn't work? If not - don't upgrade the Bios. Even with Asus I am sure the chances to cause problems were higher than to get any real advantages during runtime.
Last comment for now: the 32 GB are stable. No crashes, nothing. Only took an additional minute during the first boot. I guess the board did some tests with the new detected RAM module.
