Hi,

I have an AMD 6000+ CPU. I have now just returned my 3rd ASUS MB Micro ATX MB in a row. Every single one made this incredibly annoying high-pitched "dog whistle" sound (like a bad capacitor) when I tried to run the computer.

What gives? I had always heard ASUS was so great and I like their BIOS, but am having zero luck. I finally broke down and bought and ECS MB thinking that maybe it was just my CPU that had gone bad, but no, it was def the MB. This ECS MB is totally silent.

I am looking to maybe upgrade to a 780G chipset and wanted to give ASUS another try, but I'm gunshy at this point.

Make suer your MB can handle the CPU. Some micro atx boards can not take the high power cpus like Phenoms or 6000+.

Make sure you have an appropriately sized power supply as well. It could be that the ASUS was being underpowered.

Hahah Gigabyte was right and they are using crappy capacitors! I've always bought ASUS though and never had problems before, I think my next motherboard shall be a gigabyte.

Was the PCI-E power connector plugged into the GPU during these tests?
What mobo was it? Did it have an additional molex power connector on it? Was that connector plugged in?
