The -UD3P is a great motherboard if you want to OC your FX-8350. I've got a Rev2 that works just dandy.
The board technically shouldn't be running 125w CPU's it really can't handle them , thermally or power wise.
That would be incorrect. The FX-8350 is qualified for that motherboard.
It will Turbo. It will run 8 cores @ 4GHz 100% load. When stressing at 100% over an extended period, it will run 6 cores @ 4GHz and down-clock 2 cores to 1400GHz while dropping the volts.
There is a setting in the BIOS (*APM*) that allows you disable the core-throttling if yee wants to take yer chances ... not advisable for the "long-term"
