Can someone recommend a good overclock device for my situation?
There is no such thing as an overclock device, and you definitely don't need one, you need to
underclock to get your current CPU to work properly with your existing board. You're best off trying to underclock through changing your BIOS settings. There is software like AMD Overdrive that you could maybe use, but it tends not to offer a lot of options and may not work all that well. If you're really not comfortable doing any of this, then you're going to have to take your computer to a technician to have him replace the board with something more suitable, or downgrade your CPU to something that has a lower TDP and won't throttle on your existing board.
