I don't think thats accurate as all the Sandy Bridge CPU's will have it's clock tied to a fixed value. Can't remember the reson on this but it's a fact. In that case none support overclocking unless it's an unlocked multiplier CPU, those are the ones ending with a K.
I don't think chipset plays any role on that. I might be wrong tho.
