Best memory (2*512) for Epox 9NPA+ Ultra

I Have problems with my new setup see sign! The only thing that I kept was my Crucial BallistiX from my old setup (s754), but They wont work i DUAL CHANNEL, tested one by one, then they worked like a charm, but in dual channel I got ERRORS after 10min and in SuperP1 32mb after 5 min! So now I need a very OC frendly ddr for my setup! Please help me to find them!
