That motherboard has a warning on the MSI site in nice big red letters, that it does not support 200W CPUs.
You are certainly getting VRM and power delivery throttling of your motherboard which will result in huge performance loss for your CPU. Your only real solution is to get an appropriate motherboard. If you persist with running this CPU on that motherboard, you will rapidly burn out your power delivery, and then will need a new motherboard anyway.
Your CPU cooler is also too weak, but fixing that will still leave the far more serious motherboard problem.
The MSI 970 Gaming is a great motherboard for FX 8350 or 8370. It cannot handle a FX9xxx anything.
