Dolphin crashing frequently

Hey I would really appreciate if someone helps me stop dolphin from crashing. I have an Amd a8-5550m apu with radeon tm hd graphics processor, radeon 8550g + 8750m dual graphics, with 6gb of ram. I am trying to play fire emblem path of radience but i cant play more than 5 to 10 mins without it crashing. I have look on many threads and all i get is people saying nempunk which i have never used anything with it. So I cant disable it.
=( help please!
