Should I RMA both mobo and PSU?

post #1 of 5
Thread Starter 
For the coil whine issue... just talked to MSI on the phone and was told they'd process my RMA sometime today.

The corsair people said my RMA was approved already, but they're not sure if its a PSU or mobo issue.

If the noise is coming from cpu/ram area, could it be caused by a defective PSU?

Also, for the +12v line it says +8V or +10V in hwmonitor and speedfan. Is this normal?

in bios it shows +12V as +12.03V.. but in hwmonitor it doesnt =/

no its definitely the mobo. i followed MSI's advice and took out mobo outside system and determined i need RMA cuz its coming from CPU/ram area.

turned on APS mode and the noise is gone... what does APS mode do? Is it harmful?

Ok so i took off APS and put it back to intel SVID mode

turned off C1E and left C state enabled... got rid of noise.

If I had to do those to get the whine sound to go away, does it mean my motherboard was defective?

Please guys I need help this is my first build/first problem lol
