I'm relatively new at overclocking, but it seems to me that if your CPU overclock is stable you should just leave it as it is. If however you want to increase your CPU OC, you should do that first. When it starts to become unstable in something like Prime95 you should start to gradually loosen the timings on your RAM. What timings are you using now? Mine is set at AUTO at 2325 1T and no overclock. Maybe someone who understands timings can explain in more detail.
