FX-8120 not compatible with Gigabyte motherboard?

Solution
says "The current system does not support the cpu. If wish to continue, the cpu will be under clocked to maintain stability".
Because the FX 8120 has 125W TDP, you can see the MB can support up to 95W TDP Fx series cpu, that is why you will get the message. You will need a good AMD 970 chipset MB, which has more power phase to power the 125W fx series cpu. But you are hard to find it, only can find the used one from ebay or amazon.
