So I increased my i7 920 to 185x20: 3.7ghz. Increased the vcore to 1.35V and vtt to 1.34V. The cpu is still running surprisingly nice and cool. My question is: how much more % performance would I get from 3.7ghz to 4ghz? I've not changed anything to do with my ram, is my ram now also fully overclocked thanks to the fsb increase? The ram voltage is still on auto, should I change that? Ram is 6gb 1600mhz 8-8-8-24 Lastly what do the ram multipliers mean? I tried 12.0x and 10.0x. It didn't like that, so currently have it on 6.0x. Any help is greatly appreciated.
