Yes I get the high-pitch noise problem, I posted the problem on this forum 2 weeks ago, but nobody commented on it. Is this a really rare problem with the motherboard, or are most people deaf?
What power supply you use?
Do you have another power supply to try? - perhaps the noise disappears...
Try disabling CPU Enhanced Halt (C1E) in BIOS - it probably will reduce the noise, but CPU's energy consumption will increase in system's idle tasks.
Please write here if you solve the problem, or that either will change or not.
It is possible that the described problems may arise for many people with a whole new line of motherboards X58A (GA-X58A-UD3R, GA-X58A-UD5, GA-X58A-UD7...)
I'd like to hear reviews of all the owners of these boards if they have or not any such problems
