Wow, my mistake entirely. Thanks for the help.
Try updating to BIOS version F5 first, just to make sure it's not an old BIOS causing problems.
Although I do not that the CPU list has nothing over 95W on it. Some of the older AMD boards were capped at 95W and your CPU is a 125W chip. It might be capping the watts by throttling back the CPU.
I think the list is current because the 6300 is on it.
