Alright thanks for the clarification. So memory amount is only important because of the DAG file? As I'm sure you can tell im very new to mining. Any idea what I should do with my core clock though, clock it up or just leave it at default?
Core clock is nothing to worry about until you up the memory clock and start to get problems. I raised my memory clock to +600 and needed to raise the core clock to +100 to compensate for fluctuations.
Download GPUz and fond out what memory you have. If its hynix then you wont be able to OC much, micron is better but samsung is best.
