Maybe a late response but i have the same motherboard and CPU as you and i was also screwing with it for 2 days.
Here is the FIX:
Enter the Bios from your motherboard.
Go to Jumpfree/CPU config > DISABLE "AMD TURBO CORE"
Do this fix and it will work! I think many people with processors that have AMD Turbo Core have the same issue, and i think this needs to be set in the Niresh Install Guide
