I don't think it'll go that high. I have a SS7 HS/fan on the GPU, and I have cut apart a 1" tall PII HS and put one on each memory modle. I have a hole in the bottom of my case with a fan mounted over it. The fan is supporting the weight and cooling memory heatsinks. I can't get it a single MHz over 185 stably. I can run windows at 195, but what good is that? I can do everything at 185 though.
Overclocking is like supercharging. It's not necessary, but it sure is fun to have the fastest in town!!
