What is the ppl of my msi ms7184t

Just tell us how much you have to spend now and what you want to do and we will save you the research time.

To more directly answer your question, this board is commonly from major OEMs like HP and their BIOSs generally don't let you OC anything anyway even if you know what the code is. They also don't tell you the code to further block you from even attempting it.
