Re: Which C2D??
Well heres how it works. Intel creates all of their conroes the same and trys to make them all X6800. However a lot run too hot for them to be considered the extreme version so they just downgrade them until where the heat is suitable to sell it. They disabled the cache on the 4MB becuase the extra cache makes it run a little hotter. This way they can keep good product control but still sell most of the chips they created.
And no you cannot unlock the cache.
