I know, and I'm not trying to say otherwise. I even suggested that people keep it lower than their turbo (38-39) until finding their multi and then maybe mess with it. The reason I needed a little more CPU core voltage to pass stress tests with a higher uncore could be because of this increased performance. It is just a theory, but I have the data to support it above. Higher Uncore (cache) ratio does effect stress testing stability, and it could be because it is bottlenecking. I am happy with my cache ratio at 4.2 GHz and I won't push it any further. I just thought others would like to know that there is extra cache bandwidth there with the more extensive programs.
