Even most Venice 3000+s can reach 2.5 GHz, while good ones can do 2.7+. If your winnie only does 2.2, then it's a pretty bad chip. Sell it to someone not interested in OCing and pick up a new or used Venice (that is proven to OC well) if you want to see a slight increase in performance. Otherwise, wait until the X2s fall in price and get one of those when the time comes.
